Description

MACROLIDE-NOX4 CONJUGATES AND USES THEREOF CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This Application claims the benefit of U.S. Application No.63/535,218, filed on August 29, 2023, the contents of which are incorporated herein by reference in their entirety. STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH [0002] This invention was made with government support under grant number W81XWH-17-1- 0443 awarded by the Department of Defense. The government has certain rights in the invention. BACKGROUND [0003] The regulation of redox homeostasis is crucial for the maintenance of normal cellular growth, metabolism, and survival. Oxidative stress is defined as the imbalance between the production of reactive oxygen species (ROS) and the capability of the cell to elicit an effective antioxidant response. Several sources of ROS in cells and tissue have been identified, including mitochondrial electron transfer chain (Liu et al. (2002) J. Neurochem.80(5): 780-787) and NADPH oxidase (NOX) enzymes (Bedhard and Krause (2007) Physiol. Rev.87(1): 245-313). NOX-derived ROS have been identified as the main source of oxidative stress, which promotes key events in the development of fibrotic diseases (such as skin fibrosis (Babalola et al. (2014) Arch. Dermatol. Res.306(4): 313-330), idiopathic pulmonary fibrosis (IPF) (Hecker et al. (2012) Cell Mol. Life Sci.69(14): 2365-2371), liver fibrosis (Minicis and Brenner (2007) Arch. Biochem. Biophys.462(2): 266-272), and kidney fibrosis (Holterman et al. (2015) Clin. Sci. (Lond.) 128(8): 465-481), and acute respiratory distress syndrome (ARDS) (Kellner et al. (2017) Pulmonary Vasculature Redox Signaling in Health and Disease 967: 105-137), as well as the initiation and progression of cancer (Roy et al. (2015) Clinical Sci. (Lond.) 128(12): 863-875). [0004] Fibrosis is a complex disease characterized by excessive synthesis and accumulation of extracellular matrices that occur as a result of activation and proliferation of fibroblasts and myofibroblasts. Notably, nearly 45% of all naturally-occurring deaths in the western world are attributed to some form of fibrotic disease (Bitterman and Henke (1991) Chest 99(3 Suppl): 81s- 84s). Briefly, the presence of ROS is believed to activate transforming growth factor beta (TGF- β) signaling pathways, then induces elevated production of NOX4-generated ROS (Chen et al. (2013) Biochem. Biophys. Res. Commun.430(3): 918-925). The presence of NOX4-generated ROS, in turn, activates various pathways that ultimately lead to fibrosis. Indeed, NOX4 mRNA expression has been found to be upregulated in both pulmonary fibroblasts isolated from IPF patients (Amara et al. (2010) Thorax 65(8): 733-738) and skin fibroblasts from scleroderma patients (Spadoni et al. (2015) Arthritis Rheumatol.67(6): 1611-1622), as well as in a number of in vivo fibrosis models, including liver fibrosis (Aoyama et al. (2012) Hepatology (Baltimore Md.) 56(6): 2316-2327), pulmonary fibrosis (Jarman et al. (2014) Am. J. Respir. Cell Mol. Biol. 50(1): 158-169; Hecker et al. (2009) Nat. Med.15 (9): 1077-1081), and diabetic neuropathy (kidney fibrosis associated with diabetes mellitus) (Sedeek et al. (2010) Am. J. Physiol. – Renal Physiol.299(6): F1348-F1358). In view of such research, suppression of NOX4 activity (by, for example, a NOX4 inhibitor) has been investigated as a possible route for treating fibrotic disorders. See, e.g., U.S. Patent No.10,654,802. [0005] High expression of NOX4 has also been detected in several cancer types including gliomas (Shono et al. (2008) Int. J. Cancer 123(4): 787-792), melanoma (Yamaura et al. (2009) Cancer Res.69(6): 2647-2654), breast cancer (Graham et al. (2010) Cancer Biol. Ther.10(3): 223-231), ovarian cancer (Graham et al. (2010) Cancer Biol. Ther.10(3): 223-231), and pancreatic cancer (Hiraga et al. (2013) Anticancer Res.33(10): 4431-4438). In cancer cell lines, elevated levels of NOX4 are associated with PI3K/Akt-regulated cell proliferation and invasion (Zhang et al. (2014) Oncotarget 5(12): 4392-4405), TGF-β/SMAD3-driven EMT and cell migration (Boudreau et al. (2012) Free Radic. Biol. Med.53(7): 1489-1499), as well as Tks5- dependent invadopodia formation (Diaz et al. (2009) Sci. Signal.2(88): ra53). Depletion of NOX4 with siRNA treatment significantly reduced tumor growth in the in vivo models of bladder cancer (Shimada et al. (2011) BMC Urol.11(1): 1-12), renal cancer (Gregg et al. (2014) Cancer Res.74(13): 3501-3511), and glioblastoma (Hsieh et al. (2011) PLoS One 6(9): e23945). Without wishing to be bound by theory, these results suggest that NOX4 is a potential target for pharmacological intervention for cancer treatment. [0006] ARDS is a critical syndrome caused by heterogeneous pathologic factors and characterized by acute development of respiratory failure, bilateral diffuse lung infiltrations, and severe hypoxemia. See, e.g., Kellner et al. (2017) Pulmonary Vasculature Redox Signaling in Health and Disease 967: 105-137. The severity of ARDS is associated with poor prognosis and higher mortality. Id. Moreover, the recent global COVID-19 pandemic has attenuated the urgent need to address ARDS, as this syndrome is the leading cause of death among COVI-19 patients (Wu C, et al. (2020) JAMA Intern Med.180(7):934-943). Critical pathological features of ARDS (e.g., loss of lung endothelial barrier integrity and inflammatory injury) are strongly associated with increased oxidative stress; however, clinical trials using antioxidant treatments have failed to reduce mortality in ARDS patients. [0007] Importantly, no cure for most of these diseases has yet been identified. Current approaches to treating fibrotic diseases, for example, have thus far remained limited to attempts at slowing down disease progression (e.g., via administration of pirfenidone for pulmonary fibrosis). For cancer, there are several treatment options, including chemotherapy, surgery, radiation, immunotherapy, and others. Although cures can be achieved in some cases (e.g., by early diagnosis), resistance and recurrence are common. Moreover, current treatment options remain plagued by the risk of off-target toxicities resulting from systemic exposure. Thus, new treatments are desired, and, ideally, those that are enriched or that preferentially accumulate at disease sites to elicit targeted inhibition of NOX4. Accordingly, there exists a need for targeted NOX4 inhibitors for use in the treatment of fibrotic disorders, ARDS, and cancer.

Accordingly, where a method claim does not specifically state in the claims or description that the steps are to be limited to a specific order, it is no way intended that an order be inferred, in any respect. This holds for any possible non-express basis for interpretation, including matters of logic with respect to arrangement of steps or operational flow, plain meaning derived from grammatical organization or punctuation, or the number or type of aspects described in the specification. [0041] Throughout this application, various publications are referenced. The disclosures of these publications in their entireties are hereby incorporated by reference into this application in order to more fully describe the state of the art to which this pertains. The references disclosed are also individually and specifically incorporated by reference herein for the material contained in them that is discussed in the sentence in which the reference is relied upon. Nothing herein is to be construed as an admission that the present application is not entitled to antedate such publication by virtue of prior invention. Further, stated publication dates may be different from actual publication dates, which can require independent confirmation. A. DEFINITIONS [0042] As used in the specification and the appended claims, the singular forms “a,” “an” and “the” include plural referents unless the context clearly dictates otherwise. Thus, for example, reference to “a functional group,” “an alkyl,” or “a residue” includes mixtures of two or more such functional groups, alkyls, or residues, and the like. [0043] As used in the specification and in the claims, the term “comprising” can include the aspects “consisting of” and “consisting essentially of.” [0044] Ranges can be expressed herein as from “about” one particular value, and/or to “about” another particular value. When such a range is expressed, another aspect includes from the one particular value and/or to the other particular value. Similarly, when values are expressed as approximations, by use of the antecedent “about,” it will be understood that the particular value forms another aspect. It will be further understood that the endpoints of each of the ranges are significant both in relation to the other endpoint, and independently of the other endpoint. It is also understood that there are a number of values disclosed herein, and that each value is also herein disclosed as “about” that particular value in addition to the value itself. For example, if the value “10” is disclosed, then “about 10” is also disclosed. It is also understood that each unit between two particular units are also disclosed. For example, if 10 and 15 are disclosed, then 11, 12, 13, and 14 are also disclosed. [0045] As used herein, the terms “about” and “at or about” mean that the amount or value in question can be the value designated some other value approximately or about the same. It is generally understood, as used herein, that it is the nominal value indicated ±10% variation unless otherwise indicated or inferred. The term is intended to convey that similar values promote equivalent results or effects recited in the claims. That is, it is understood that amounts, sizes, formulations, parameters, and other quantities and characteristics are not and need not be exact, but can be approximate and/or larger or smaller, as desired, reflecting tolerances, conversion factors, rounding off, measurement error and the like, and other factors known to those of skill in the art. In general, an amount, size, formulation, parameter or other quantity or characteristic is “about” or “approximate” whether or not expressly stated to be such. It is understood that where “about” is used before a quantitative value, the parameter also includes the specific quantitative value itself, unless specifically stated otherwise. [0046] References in the specification and concluding claims to parts by weight of a particular element or component in a composition denotes the weight relationship between the element or component and any other elements or components in the composition or article for which a part by weight is expressed. Thus, in a compound containing 2 parts by weight of component X and 5 parts by weight component Y, X and Y are present at a weight ratio of 2:5, and are present in such ratio regardless of whether additional components are contained in the compound. [0047] A weight percent (wt. %) of a component, unless specifically stated to the contrary, is based on the total weight of the formulation or composition in which the component is included. [0048] As used herein, the terms “optional” or “optionally” means that the subsequently described event or circumstance can or cannot occur, and that the description includes instances where said event or circumstance occurs and instances where it does not. [0049] As used herein, the term “subject” can be a vertebrate, such as a mammal, a fish, a bird, a reptile, or an amphibian. Thus, the subject of the herein disclosed methods can be a human, non- human primate, horse, pig, rabbit, dog, sheep, goat, cow, cat, guinea pig, or rodent. The term does not denote a particular age or sex. Thus, adult and newborn subjects, as well as fetuses, whether male or female, are intended to be covered. In one aspect, the subject is a mammal. A patient refers to a subject afflicted with a disease or disorder. The term “patient” includes human and veterinary subjects. [0050] As used herein, the term “treatment” refers to the medical management of a patient with the intent to cure, ameliorate, stabilize, or prevent a disease, pathological condition, or disorder. This term includes active treatment, that is, treatment directed specifically toward the improvement of a disease, pathological condition, or disorder, and also includes causal treatment, that is, treatment directed toward removal of the cause of the associated disease, pathological condition, or disorder. In addition, this term includes palliative treatment, that is, treatment designed for the relief of symptoms rather than the curing of the disease, pathological condition, or disorder; preventative treatment, that is, treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder; and supportive treatment, that is, treatment employed to supplement another specific therapy directed toward the improvement of the associated disease, pathological condition, or disorder. In various aspects, the term covers any treatment of a subject, including a mammal (e.g., a human), and includes: (i) preventing the disease from occurring in a subject that can be predisposed to the disease but has not yet been diagnosed as having it; (ii) inhibiting the disease, i.e., arresting its development; or (iii) relieving the disease, i.e., causing regression of the disease. In one aspect, the subject is a mammal such as a primate, and, in a further aspect, the subject is a human. The term “subject” also includes domesticated animals (e.g., cats, dogs, etc.), livestock (e.g., cattle, horses, pigs, sheep, goats, etc.), and laboratory animals (e.g., mouse, rabbit, rat, guinea pig, fruit fly, etc.). [0051] As used herein, the term “prevent” or “preventing” refers to precluding, averting, obviating, forestalling, stopping, or hindering something from happening, especially by advance action. It is understood that where reduce, inhibit or prevent are used herein, unless specifically indicated otherwise, the use of the other two words is also expressly disclosed. [0052] As used herein, the term “diagnosed” means having been subjected to a physical examination by a person of skill, for example, a physician, and found to have a condition that can be diagnosed or treated by the compounds, compositions, or methods disclosed herein. [0053] As used herein, the terms “administering” and “administration” refer to any method of providing a pharmaceutical preparation to a subject. Such methods are well known to those skilled in the art and include, but are not limited to, oral administration, transdermal administration, administration by inhalation, nasal administration, topical administration, intravaginal administration, ophthalmic administration, intraaural administration, intracerebral administration, rectal administration, sublingual administration, buccal administration, and parenteral administration, including injectable such as intravenous administration, intra-arterial administration, intramuscular administration, and subcutaneous administration. Administration can be continuous or intermittent. In various aspects, a preparation can be administered therapeutically; that is, administered to treat an existing disease or condition. In further various aspects, a preparation can be administered prophylactically; that is, administered for prevention of a disease or condition. [0054] As used herein, the terms “effective amount” and “amount effective” refer to an amount that is sufficient to achieve the desired result or to have an effect on an undesired condition. For example, a “therapeutically effective amount” refers to an amount that is sufficient to achieve the desired therapeutic result or to have an effect on undesired symptoms, but is generally insufficient to cause adverse side effects. The specific therapeutically effective dose level for any particular patient will depend upon a variety of factors including the disorder being treated and the severity of the disorder; the specific composition employed; the age, body weight, general health, sex and diet of the patient; the time of administration; the route of administration; the rate of excretion of the specific compound employed; the duration of the treatment; drugs used in combination or coincidental with the specific compound employed and like factors well known in the medical arts. For example, it is well within the skill of the art to start doses of a compound at levels lower than those required to achieve the desired therapeutic effect and to gradually increase the dosage until the desired effect is achieved. If desired, the effective daily dose can be divided into multiple doses for purposes of administration. Consequently, single dose compositions can contain such amounts or submultiples thereof to make up the daily dose. The dosage can be adjusted by the individual physician in the event of any contraindications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products. In further various aspects, a preparation can be administered in a “prophylactically effective amount”; that is, an amount effective for prevention of a disease or condition. [0055] As used herein, “dosage form” means a pharmacologically active material in a medium, carrier, vehicle, or device suitable for administration to a subject. A dosage form can comprise a disclosed compound, a product of a disclosed method of making, or a salt, solvate, or polymorph thereof, in combination with a pharmaceutically acceptable excipient, such as a preservative, buffer, saline, or phosphate buffered saline. Dosage forms can be made using conventional pharmaceutical manufacturing and compounding techniques. Dosage forms can comprise inorganic or organic buffers (e.g., sodium or potassium salts of phosphate, carbonate, acetate, or citrate) and pH adjustment agents (e.g., hydrochloric acid, sodium or potassium hydroxide, salts of citrate or acetate, amino acids and their salts) antioxidants (e.g., ascorbic acid, alpha- tocopherol), surfactants (e.g., polysorbate 20, polysorbate 80, polyoxyethylene9-10 nonyl phenol, sodium desoxycholate), solution and/or cryo/lyo stabilizers (e.g., sucrose, lactose, mannitol, trehalose), osmotic adjustment agents (e.g., salts or sugars), antibacterial agents (e.g., benzoic acid, phenol, gentamicin), antifoaming agents (e.g., polydimethylsilozone), preservatives (e.g., thimerosal, 2-phenoxyethanol, EDTA), polymeric stabilizers and viscosity-adjustment agents (e.g., polyvinylpyrrolidone, poloxamer 488, carboxymethylcellulose) and co-solvents (e.g., glycerol, polyethylene glycol, ethanol). A dosage form formulated for injectable use can have a disclosed compound, a product of a disclosed method of making, or a salt, solvate, or polymorph thereof, suspended in sterile saline solution for injection together with a preservative. [0056] As used herein, “kit” means a collection of at least two components constituting the kit. Together, the components constitute a functional unit for a given purpose. Individual member components may be physically packaged together or separately. For example, a kit comprising an instruction for using the kit may or may not physically include the instruction with other individual member components. Instead, the instruction can be supplied as a separate member component, either in a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation. [0057] As used herein, “instruction(s)” means documents describing relevant materials or methodologies pertaining to a kit. These materials may include any combination of the following: background information, list of components and their availability information (purchase information, etc.), brief or detailed protocols for using the kit, trouble-shooting, references, technical support, and any other related documents. Instructions can be supplied with the kit or as a separate member component, either as a paper form or an electronic form which may be supplied on computer readable memory device or downloaded from an internet website, or as recorded presentation. Instructions can comprise one or multiple documents, and are meant to include future updates. [0058] As used herein, the terms “therapeutic agent” include any synthetic or naturally occurring biologically active compound or composition of matter which, when administered to an organism (human or nonhuman animal), induces a desired pharmacologic, immunogenic, and/or physiologic effect by local and/or systemic action. The term therefore encompasses those compounds or chemicals traditionally regarded as drugs, vaccines, and biopharmaceuticals including molecules such as proteins, peptides, hormones, nucleic acids, gene constructs and the like. Examples of therapeutic agents are described in well-known literature references such as the Merck Index (14th edition), the Physicians' Desk Reference (64th edition), and The Pharmacological Basis of Therapeutics (12th edition) , and they include, without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of a disease or illness; substances that affect the structure or function of the body, or pro-drugs, which become biologically active or more active after they have been placed in a physiological environment. For example, the term “therapeutic agent” includes compounds or compositions for use in all of the major therapeutic areas including, but not limited to, adjuvants; anti-infectives such as antibiotics and antiviral agents; analgesics and analgesic combinations, anorexics, anti-inflammatory agents, anti-epileptics, local and general anesthetics, hypnotics, sedatives, antipsychotic agents, neuroleptic agents, antidepressants, anxiolytics, antagonists, neuron blocking agents, anticholinergic and cholinomimetic agents, antimuscarinic and muscarinic agents, antiadrenergics, antiarrhythmics, antihypertensive agents, hormones, and nutrients, antiarthritics, antiasthmatic agents, anticonvulsants, antihistamines, antinauseants, antineoplastics, antipruritics, antipyretics; antispasmodics, cardiovascular preparations (including calcium channel blockers, beta-blockers, beta-agonists and antiarrythmics), antihypertensives, diuretics, vasodilators; central nervous system stimulants; cough and cold preparations; decongestants; diagnostics; hormones; bone growth stimulants and bone resorption inhibitors; immunosuppressives; muscle relaxants; psychostimulants; sedatives; tranquilizers; proteins, peptides, and fragments thereof (whether naturally occurring, chemically synthesized or recombinantly produced); and nucleic acid molecules (polymeric forms of two or more nucleotides, either ribonucleotides (RNA) or deoxyribonucleotides (DNA) including both double- and single-stranded molecules, gene constructs, expression vectors, antisense molecules and the like), small molecules (e.g., doxorubicin) and other biologically active macromolecules such as, for example, proteins and enzymes. The agent may be a biologically active agent used in medical, including veterinary, applications and in agriculture, such as with plants, as well as other areas. The term "therapeutic agent" also includes without limitation, medicaments; vitamins; mineral supplements; substances used for the treatment, prevention, diagnosis, cure or mitigation of disease or illness; or substances which affect the structure or function of the body; or pro- drugs, which become biologically active or more active after they have been placed in a predetermined physiological environment. [0059] The term “pharmaceutically acceptable” describes a material that is not biologically or otherwise undesirable, i.e., without causing an unacceptable level of undesirable biological effects or interacting in a deleterious manner. [0060] As used herein, the term “derivative” refers to a compound having a structure derived from the structure of a parent compound (e.g., a compound disclosed herein) and whose structure is sufficiently similar to those disclosed herein and based upon that similarity, would be expected by one skilled in the art to exhibit the same or similar activities and utilities as the claimed compounds, or to induce, as a precursor, the same or similar activities and utilities as the claimed compounds. Exemplary derivatives include salts, esters, amides, salts of esters or amides, and N-oxides of a parent compound. [0061] As used herein, the term “pharmaceutically acceptable carrier” refers to sterile aqueous or nonaqueous solutions, dispersions, suspensions or emulsions, as well as sterile powders for reconstitution into sterile injectable solutions or dispersions just prior to use. Examples of suitable aqueous and nonaqueous carriers, diluents, solvents or vehicles include water, ethanol, polyols (such as glycerol, propylene glycol, polyethylene glycol and the like), carboxymethylcellulose and suitable mixtures thereof, vegetable oils (such as olive oil) and injectable organic esters such as ethyl oleate. Proper fluidity can be maintained, for example, by the use of coating materials such as lecithin, by the maintenance of the required particle size in the case of dispersions and by the use of surfactants. These compositions can also contain adjuvants such as preservatives, wetting agents, emulsifying agents and dispersing agents. Prevention of the action of microorganisms can be ensured by the inclusion of various antibacterial and antifungal agents such as paraben, chlorobutanol, phenol, sorbic acid and the like. It can also be desirable to include isotonic agents such as sugars, sodium chloride and the like. Prolonged absorption of the injectable pharmaceutical form can be brought about by the inclusion of agents, such as aluminum monostearate and gelatin, which delay absorption. Injectable depot forms are made by forming microencapsule matrices of the drug in biodegradable polymers such as polylactide-polyglycolide, poly(orthoesters) and poly(anhydrides). Depending upon the ratio of drug to polymer and the nature of the particular polymer employed, the rate of drug release can be controlled. Depot injectable formulations are also prepared by entrapping the drug in liposomes or microemulsions which are compatible with body tissues. The injectable formulations can be sterilized, for example, by filtration through a bacterial-retaining filter or by incorporating sterilizing agents in the form of sterile solid compositions which can be dissolved or dispersed in sterile water or other sterile injectable media just prior to use. Suitable inert carriers can include sugars such as lactose. Desirably, at least 95% by weight of the particles of the active ingredient have an effective particle size in the range of 0.01 to 10 micrometers. [0062] A residue of a chemical species, as used in the specification and concluding claims, refers to the moiety that is the resulting product of the chemical species in a particular reaction scheme or subsequent formulation or chemical product, regardless of whether the moiety is actually obtained from the chemical species. Thus, an ethylene glycol residue in a polyester refers to one or more -OCH2CH2O- units in the polyester, regardless of whether ethylene glycol was used to prepare the polyester. Similarly, a sebacic acid residue in a polyester refers to one or more - CO(CH2)8CO- moieties in the polyester, regardless of whether the residue is obtained by reacting sebacic acid or an ester thereof to obtain the polyester. [0063] As used herein, the term “substituted” is contemplated to include all permissible substituents of organic compounds. In a broad aspect, the permissible substituents include acyclic and cyclic, branched and unbranched, carbocyclic and heterocyclic, and aromatic and nonaromatic substituents of organic compounds. Illustrative substituents include, for example, those described below. The permissible substituents can be one or more and the same or different for appropriate organic compounds. For purposes of this disclosure, the heteroatoms, such as nitrogen, can have hydrogen substituents and/or any permissible substituents of organic compounds described herein which satisfy the valences of the heteroatoms. This disclosure is not intended to be limited in any manner by the permissible substituents of organic compounds. Also, the terms “substitution” or “substituted with” include the implicit proviso that such substitution is in accordance with permitted valence of the substituted atom and the substituent, and that the substitution results in a stable compound, e.g., a compound that does not spontaneously undergo transformation such as by rearrangement, cyclization, elimination, etc. It is also contemplated that, in certain aspects, unless expressly indicated to the contrary, individual substituents can be further optionally substituted (i.e., further substituted or unsubstituted). [0064] In defining various terms, “A1,” “A2,” “A3,” and “A4” are used herein as generic symbols to represent various specific substituents. These symbols can be any substituent, not limited to those disclosed herein, and when they are defined to be certain substituents in one instance, they can, in another instance, be defined as some other substituents. [0065] The term “aliphatic” or “aliphatic group,” as used herein, denotes a hydrocarbon moiety that may be straight-chain (i.e., unbranched), branched, or cyclic (including fused, bridging, and spirofused polycyclic) and may be completely saturated or may contain one or more units of unsaturation, but which is not aromatic. Unless otherwise specified, aliphatic groups contain 1- 20 carbon atoms. Aliphatic groups include, but are not limited to, linear or branched, alkyl, alkenyl, and alkynyl groups, and hybrids thereof such as (cycloalkyl)alkyl, (cycloalkenyl)alkyl or (cycloalkyl)alkenyl. [0066] The term “alkyl” as used herein is a branched or unbranched saturated hydrocarbon group of 1 to 24 carbon atoms, such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, s-butyl, t- butyl, n-pentyl, isopentyl, s-pentyl, neopentyl, hexyl, heptyl, octyl, nonyl, decyl, dodecyl, tetradecyl, hexadecyl, eicosyl, tetracosyl, and the like. The alkyl group can be cyclic or acyclic. The alkyl group can be branched or unbranched. The alkyl group can also be substituted or unsubstituted. For example, the alkyl group can be substituted with one or more groups including, but not limited to, cycloalkyl, alkoxy, amino, ether, halide, hydroxy, nitro, silyl, sulfo- oxo, or thiol, as described herein. A “lower alkyl” group is an alkyl group containing from one to six (e.g., from one to four) carbon atoms. The term alkyl group can also be a C1 alkyl, C1-C2 alkyl, C1-C3 alkyl, C1-C4 alkyl, C1-C5 alkyl, C1-C6 alkyl, C1-C7 alkyl, C1-C8 alkyl, C1-C9 alkyl, C1-C10 alkyl, and the like up to and including a C1-C24 alkyl. [0067] Throughout the specification “alkyl” is generally used to refer to both unsubstituted alkyl groups and substituted alkyl groups; however, substituted alkyl groups are also specifically referred to herein by identifying the specific substituent(s) on the alkyl group. For example, the term “halogenated alkyl” or “haloalkyl” specifically refers to an alkyl group that is substituted with one or more halide, e.g., fluorine, chlorine, bromine, or iodine. Alternatively, the term “monohaloalkyl” specifically refers to an alkyl group that is substituted with a single halide, e.g. fluorine, chlorine, bromine, or iodine. The term “polyhaloalkyl” specifically refers to an alkyl group that is independently substituted with two or more halides, i.e. each halide substituent need not be the same halide as another halide substituent, nor do the multiple instances of a halide substituent need to be on the same carbon. The term “alkoxyalkyl” specifically refers to an alkyl group that is substituted with one or more alkoxy groups, as described below. The term “aminoalkyl” specifically refers to an alkyl group that is substituted with one or more amino groups. The term “hydroxyalkyl” specifically refers to an alkyl group that is substituted with one or more hydroxy groups. When “alkyl” is used in one instance and a specific term such as “hydroxyalkyl” is used in another, it is not meant to imply that the term “alkyl” does not also refer to specific terms such as “hydroxyalkyl” and the like. [0068] This practice is also used for other groups described herein. That is, while a term such as “cycloalkyl” refers to both unsubstituted and substituted cycloalkyl moieties, the substituted moieties can, in addition, be specifically identified herein; for example, a particular substituted cycloalkyl can be referred to as, e.g., an “alkylcycloalkyl.” Similarly, a substituted alkoxy can be specifically referred to as, e.g., a “halogenated alkoxy,” a particular substituted alkenyl can be, e.g., an “alkenylalcohol,” and the like. Again, the practice of using a general term, such as “cycloalkyl,” and a specific term, such as “alkylcycloalkyl,” is not meant to imply that the general term does not also include the specific term. [0069] The term “cycloalkyl” as used herein is a non-aromatic carbon-based ring composed of at least three carbon atoms. Examples of cycloalkyl groups include, but are not limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, norbornyl, and the like. The term “heterocycloalkyl” is a type of cycloalkyl group as defined above, and is included within the meaning of the term “cycloalkyl,” where at least one of the carbon atoms of the ring is replaced with a heteroatom such as, but not limited to, nitrogen, oxygen, sulfur, or phosphorus. The cycloalkyl group and heterocycloalkyl group can be substituted or unsubstituted. For example, the cycloalkyl group and heterocycloalkyl group can be substituted with 0, 1, 2, 3, or 4 groups independently selected from C1-C4 alkyl, C3-C7 cycloalkyl, C1-C4 alkoxy, −NH2, (C1-C4) alkylamino, (C1-C4)(C1-C4) dialkylamino, ether, halogen, −OH, C1-C4 hydroxyalkyl, −NO2, silyl, sulfo-oxo, −SH, and C1-C4 thioalkyl, as described herein. [0070] The term “polyalkylene group” as used herein is a group having two or more CH2 groups linked to one another. The polyalkylene group can be represented by the formula —(CH2)a—, where “a” is an integer of from 2 to 500. [0071] The terms “alkoxy” and “alkoxyl” as used herein to refer to an alkyl or cycloalkyl group bonded through an ether linkage; that is, an “alkoxy” group can be defined as —OA1 where A1 is alkyl or cycloalkyl as defined above. “Alkoxy” also includes polymers of alkoxy groups as just described; that is, an alkoxy can be a polyether such as —OA1—OA2 or —OA1—(OA2)a—OA3, where “a” is an integer of from 1 to 200 and A1, A2, and A3 are alkyl and/or cycloalkyl groups. [0072] The term “alkenyl” as used herein is a hydrocarbon group of from 2 to 24 carbon atoms with a structural formula containing at least one carbon-carbon double bond. Asymmetric structures such as (A1A2)C=C(A3A4) are intended to include both the E and Z isomers. This can be presumed in structural formulae herein wherein an asymmetric alkene is present, or it can be explicitly indicated by the bond symbol C=C. The alkenyl group can be substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl, aldehyde, amino, carboxylic acid, ester, ether, halide, hydroxy, ketone, azide, nitro, silyl, sulfo-oxo, or thiol, as described herein. [0073] The term “cycloalkenyl” as used herein is a non-aromatic carbon-based ring composed of at least three carbon atoms and containing at least one carbon-carbon double bound, i.e., C=C. Examples of cycloalkenyl groups include, but are not limited to, cyclopropenyl, cyclobutenyl, cyclopentenyl, cyclopentadienyl, cyclohexenyl, cyclohexadienyl, norbornenyl, and the like. The term “heterocycloalkenyl” is a type of cycloalkenyl group as defined above, and is included within the meaning of the term “cycloalkenyl,” where at least one of the carbon atoms of the ring is replaced with a heteroatom such as, but not limited to, nitrogen, oxygen, sulfur, or phosphorus. The cycloalkenyl group and heterocycloalkenyl group can be substituted or unsubstituted. For example, the cycloalkenyl group and heterocycloalkenyl group can be substituted with 0, 1, 2, 3, or 4 groups independently selected from C1-C4 alkyl, C3-C7 cycloalkyl, C1-C4 alkoxy, C2-C4 alkenyl, C3-C6 cycloalkenyl, C2-C4 alkynyl, aryl, heteroaryl, aldehyde, −NH2, (C1-C4) alkylamino, (C1-C4)(C1-C4) dialkylamino, carboxylic acid, ester, ether, halogen, −OH, C1-C4 hydroxyalkyl, ketone, azide, −NO2, silyl, sulfo-oxo, −SH, and C1-C4 thioalkyl, as described herein. [0074] The term “alkynyl” as used herein is a hydrocarbon group of 2 to 24 carbon atoms with a structural formula containing at least one carbon-carbon triple bond. The alkynyl group can be unsubstituted or substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl, aldehyde, amino, carboxylic acid, ester, ether, halide, hydroxy, ketone, azide, nitro, silyl, sulfo-oxo, or thiol, as described herein. [0075] The term “cycloalkynyl” as used herein is a non-aromatic carbon-based ring composed of at least seven carbon atoms and containing at least one carbon-carbon triple bound. Examples of cycloalkynyl groups include, but are not limited to, cycloheptynyl, cyclooctynyl, cyclononynyl, and the like. The term “heterocycloalkynyl” is a type of cycloalkenyl group as defined above, and is included within the meaning of the term “cycloalkynyl,” where at least one of the carbon atoms of the ring is replaced with a heteroatom such as, but not limited to, nitrogen, oxygen, sulfur, or phosphorus. The cycloalkynyl group and heterocycloalkynyl group can be substituted or unsubstituted. The cycloalkynyl group and heterocycloalkynyl group can be substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl, aldehyde, amino, carboxylic acid, ester, ether, halide, hydroxy, ketone, azide, nitro, silyl, sulfo-oxo, or thiol as described herein. [0076] The term “aromatic group” as used herein refers to a ring structure having cyclic clouds of delocalized π electrons above and below the plane of the molecule, where the π clouds contain (4n+2) π electrons. A further discussion of aromaticity is found in Morrison and Boyd, Organic Chemistry, (5th Ed., 1987), Chapter 13, entitled “Aromaticity,” pages 477-497, incorporated herein by reference. The term “aromatic group” is inclusive of both aryl and heteroaryl groups. [0077] The term “aryl” as used herein is a group that contains any carbon-based aromatic group including, but not limited to, benzene, naphthalene, phenyl, biphenyl, anthracene, and the like. The aryl group can be substituted or unsubstituted. The aryl group can be substituted with one or more groups including, but not limited to, alkyl, cycloalkyl, alkoxy, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, heteroaryl, aldehyde, ─NH2, carboxylic acid, ester, ether, halide, hydroxy, ketone, azide, nitro, silyl, sulfo-oxo, or thiol as described herein. The term “biaryl” is a specific type of aryl group and is included in the definition of “aryl.” In addition, the aryl group can be a single ring structure or comprise multiple ring structures that are either fused ring structures or attached via one or more bridging groups such as a carbon-carbon bond. For example, biaryl can be two aryl groups that are bound together via a fused ring structure, as in naphthalene, or are attached via one or more carbon-carbon bonds, as in biphenyl. [0078] The term “aldehyde” as used herein is represented by the formula —C(O)H. Throughout this specification “C(O)” or “CO” is a short hand notation for a carbonyl group, i.e., C=O. [0079] The terms “amine” or “amino” as used herein are represented by the formula —NA1A2, where A1 and A2 can be, independently, hydrogen or alkyl, cycloalkyl, alkenyl, cycloalkenyl, alkynyl, cycloalkynyl, aryl, or heteroaryl group as described herein.

For example, if R1 is a straight chain alkyl group, one of the hydrogen atoms of the alkyl group can optionally be substituted with a hydroxyl group, an alkoxy group, an alkyl group, a halide, and the like. Depending upon the groups that are selected, a first group can be incorporated within second group or, alternatively, the first group can be pendant (i.e., attached) to the second group. For example, with the phrase “an alkyl group comprising an amino group,” the amino group can be incorporated within the backbone of the alkyl group. Alternatively, the amino group can be attached to the backbone of the alkyl group. The nature of the group(s) that is (are) selected will determine if the first group is embedded or attached to the second group. [00101] As described herein, compounds of the invention may contain “optionally substituted” moieties. In general, the term “substituted,” whether preceded by the term “optionally” or not, means that one or more hydrogen of the designated moiety are replaced with a suitable substituent. Unless otherwise indicated, an “optionally substituted” group may have a suitable substituent at each substitutable position of the group, and when more than one position in any given structure may be substituted with more than one substituent selected from a specified group, the substituent may be either the same or different at every position. Combinations of substituents envisioned by this invention are those that result in the formation of stable or chemically feasible compounds. In is also contemplated that, in certain aspects, unless expressly indicated to the contrary, individual substituents can be further optionally substituted (i.e., further substituted or unsubstituted). [00102] The term “stable,” as used herein, refers to compounds that are not substantially altered when subjected to conditions to allow for their production, detection, and, in certain aspects, their recovery, purification, and use for one or more of the purposes disclosed herein.

Examples of suitable leaving groups include halides and sulfonate esters, including, but not limited to, triflate, mesylate, tosylate, and brosylate. [00110] The terms “hydrolysable group” and “hydrolysable moiety” refer to a functional group capable of undergoing hydrolysis, e.g., under basic or acidic conditions. Examples of hydrolysable residues include, without limitation, acid halides, activated carboxylic acids, and various protecting groups known in the art (see, for example, “Protective Groups in Organic Synthesis,” T. W. Greene, P. G. M. Wuts, Wiley-Interscience, 1999). [00111] The term “organic residue” defines a carbon containing residue, i.e., a residue comprising at least one carbon atom, and includes but is not limited to the carbon-containing groups, residues, or radicals defined hereinabove. Organic residues can contain various heteroatoms, or be bonded to another molecule through a heteroatom, including oxygen, nitrogen, sulfur, phosphorus, or the like. Examples of organic residues include but are not limited alkyl or substituted alkyls, alkoxy or substituted alkoxy, mono or di-substituted amino, amide groups, etc. Organic residues can preferably comprise 1 to 18 carbon atoms, 1 to 15, carbon atoms, 1 to 12 carbon atoms, 1 to 8 carbon atoms, 1 to 6 carbon atoms, or 1 to 4 carbon atoms. In a further aspect, an organic residue can comprise 2 to 18 carbon atoms, 2 to 15, carbon atoms, 2 to 12 carbon atoms, 2 to 8 carbon atoms, 2 to 4 carbon atoms, or 2 to 4 carbon atoms. [00112] A very close synonym of the term “residue” is the term “radical,” which as used in the specification and concluding claims, refers to a fragment, group, or substructure of a molecule described herein, regardless of how the molecule is prepared. For example, a 2,4- thiazolidinedione radical in a particular compound has the structure: , regardless of whether thiazolidinedione is used to prepare the compound. In some embodiments the radical (for example an alkyl) can be further modified (i.e., substituted alkyl) by having bonded thereto one or more “substituent radicals.” The number of atoms in a given radical is not critical to the present invention unless it is indicated to the contrary elsewhere herein. [00113] “Organic radicals,” as the term is defined and used herein, contain one or more carbon atoms. An organic radical can have, for example, 1-26 carbon atoms, 1-18 carbon atoms, 1-12 carbon atoms, 1-8 carbon atoms, 1-6 carbon atoms, or 1-4 carbon atoms. In a further aspect, an organic radical can have 2-26 carbon atoms, 2-18 carbon atoms, 2-12 carbon atoms, 2- 8 carbon atoms, 2-6 carbon atoms, or 2-4 carbon atoms. Organic radicals often have hydrogen bound to at least some of the carbon atoms of the organic radical. One example, of an organic radical that comprises no inorganic atoms is a 5, 6, 7, 8-tetrahydro-2-naphthyl radical. In some embodiments, an organic radical can contain 1-10 inorganic heteroatoms bound thereto or therein, including halogens, oxygen, sulfur, nitrogen, phosphorus, and the like. Examples of organic radicals include but are not limited to an alkyl, substituted alkyl, cycloalkyl, substituted cycloalkyl, mono-substituted amino, di-substituted amino, acyloxy, cyano, carboxy, carboalkoxy, alkylcarboxamide, substituted alkylcarboxamide, dialkylcarboxamide, substituted dialkylcarboxamide, alkylsulfonyl, alkylsulfinyl, thioalkyl, thiohaloalkyl, alkoxy, substituted alkoxy, haloalkyl, haloalkoxy, aryl, substituted aryl, heteroaryl, heterocyclic, or substituted heterocyclic radicals, wherein the terms are defined elsewhere herein. A few non-limiting examples of organic radicals that include heteroatoms include alkoxy radicals, trifluoromethoxy radicals, acetoxy radicals, dimethylamino radicals and the like. [00114] “Inorganic radicals,” as the term is defined and used herein, contain no carbon atoms and therefore comprise only atoms other than carbon. Inorganic radicals comprise bonded combinations of atoms selected from hydrogen, nitrogen, oxygen, silicon, phosphorus, sulfur, selenium, and halogens such as fluorine, chlorine, bromine, and iodine, which can be present individually or bonded together in their chemically stable combinations. Inorganic radicals have 10 or fewer, or preferably one to six or one to four inorganic atoms as listed above bonded together. Examples of inorganic radicals include, but not limited to, amino, hydroxy, halogens, nitro, thiol, sulfate, phosphate, and like commonly known inorganic radicals. The inorganic radicals do not have bonded therein the metallic elements of the periodic table (such as the alkali metals, alkaline earth metals, transition metals, lanthanide metals, or actinide metals), although such metal ions can sometimes serve as a pharmaceutically acceptable cation for anionic inorganic radicals such as a sulfate, phosphate, or like anionic inorganic radical. Inorganic radicals do not comprise metalloids elements such as boron, aluminum, gallium, germanium, arsenic, tin, lead, or tellurium, or the noble gas elements, unless otherwise specifically indicated elsewhere herein. [00115] Compounds described herein can contain one or more double bonds and, thus, potentially give rise to cis/trans (E/Z) isomers, as well as other conformational isomers. Unless stated to the contrary, the invention includes all such possible isomers, as well as mixtures of such isomers. [00116] Unless stated to the contrary, a formula with chemical bonds shown only as solid lines and not as wedges or dashed lines contemplates each possible isomer, e.g., each enantiomer and diastereomer, and a mixture of isomers, such as a racemic or scalemic mixture. Compounds described herein can contain one or more asymmetric centers and, thus, potentially give rise to diastereomers and optical isomers. Unless stated to the contrary, the present invention includes all such possible diastereomers as well as their racemic mixtures, their substantially pure resolved enantiomers, all possible geometric isomers, and pharmaceutically acceptable salts thereof. Mixtures of stereoisomers, as well as isolated specific stereoisomers, are also included. During the course of the synthetic procedures used to prepare such compounds, or in using racemization or epimerization procedures known to those skilled in the art, the products of such procedures can be a mixture of stereoisomers. [00117] Many organic compounds exist in optically active forms having the ability to rotate the plane of plane-polarized light. In describing an optically active compound, the prefixes D and L or R and S are used to denote the absolute configuration of the molecule about its chiral center(s). The prefixes d and l or (+) and (-) are employed to designate the sign of rotation of plane-polarized light by the compound, with (-) or meaning that the compound is levorotatory. A compound prefixed with (+) or d is dextrorotatory. For a given chemical structure, these compounds, called stereoisomers, are identical except that they are non- superimposable mirror images of one another. A specific stereoisomer can also be referred to as an enantiomer, and a mixture of such isomers is often called an enantiomeric mixture. A 50:50 mixture of enantiomers is referred to as a racemic mixture. Many of the compounds described herein can have one or more chiral centers and therefore can exist in different enantiomeric forms. If desired, a chiral carbon can be designated with an asterisk (*). When bonds to the chiral carbon are depicted as straight lines in the disclosed formulas, it is understood that both the (R) and (S) configurations of the chiral carbon, and hence both enantiomers and mixtures thereof, are embraced within the formula. As is used in the art, when it is desired to specify the absolute configuration about a chiral carbon, one of the bonds to the chiral carbon can be depicted as a wedge (bonds to atoms above the plane) and the other can be depicted as a series or wedge of short parallel lines is (bonds to atoms below the plane). The Cahn-Ingold-Prelog system can be used to assign the (R) or (S) configuration to a chiral carbon. [00118] Compounds described herein comprise atoms in both their natural isotopic abundance and in non-natural abundance. The disclosed compounds can be isotopically-labeled or isotopically-substituted compounds identical to those described, but for the fact that one or more atoms are replaced by an atom having an atomic mass or mass number different from the atomic mass or mass number typically found in nature. Examples of isotopes that can be incorporated into compounds of the invention include isotopes of hydrogen, carbon, nitrogen, oxygen, phosphorous, fluorine and chlorine, such as 2 H, 3 H, 13 C, 14 C, 15 N, 18 O, 17 O, 35 S, 18 F and 36 Cl, respectively. Compounds further comprise prodrugs thereof, and pharmaceutically acceptable salts of said compounds or of said prodrugs which contain the aforementioned isotopes and/or other isotopes of other atoms are within the scope of this invention. Certain isotopically-labeled compounds of the present invention, for example those into which radioactive isotopes such as 3 H and 14 C are incorporated, are useful in drug and/or substrate tissue distribution assays. Tritiated, i.e., 3 H, and carbon-14, i.e., 14 C, isotopes are particularly preferred for their ease of preparation and detectability. Further, substitution with heavier isotopes such as deuterium, i.e., 2 H, can afford certain therapeutic advantages resulting from greater metabolic stability, for example increased in vivo half-life or reduced dosage requirements and, hence, may be preferred in some circumstances. Isotopically labeled compounds of the present invention and prodrugs thereof can generally be prepared by carrying out the procedures below, by substituting a readily available isotopically labeled reagent for a non- isotopically labeled reagent. [00119] The compounds described in the invention can be present as a solvate. In some cases, the solvent used to prepare the solvate is an aqueous solution, and the solvate is then often referred to as a hydrate. The compounds can be present as a hydrate, which can be obtained, for example, by crystallization from a solvent or from aqueous solution. In this connection, one, two, three or any arbitrary number of solvent or water molecules can combine with the compounds according to the invention to form solvates and hydrates. Unless stated to the contrary, the invention includes all such possible solvates. [00120] The term “co-crystal” means a physical association of two or more molecules which owe their stability through non-covalent interaction. One or more components of this molecular complex provide a stable framework in the crystalline lattice. In certain instances, the guest molecules are incorporated in the crystalline lattice as anhydrates or solvates, see e.g. “Crystal Engineering of the Composition of Pharmaceutical Phases. Do Pharmaceutical Co- crystals Represent a New Path to Improved Medicines?” Almarasson, O., et. al., The Royal Society of Chemistry, 1889-1896, 2004. Examples of co-crystals include p-toluenesulfonic acid and benzenesulfonic acid. [00121] It is also appreciated that certain compounds described herein can be present as an equilibrium of tautomers. For example, ketones with an α-hydrogen can exist in an equilibrium of the keto form and the enol form. [00122] Likewise, amides with an N-hydrogen can exist in an equilibrium of the amide form and the imidic acid form. As another example, pyrazoles can exist in two tautomeric forms, N1-unsubstituted, 3-A3 and N1-unsubstituted, 5-A3 as shown below. [00123] Unless stated to the contrary, the invention includes all such possible tautomers. [00124] It is known that chemical substances form solids which are present in different states of order which are termed polymorphic forms or modifications. The different modifications of a polymorphic substance can differ greatly in their physical properties. The compounds according to the invention can be present in different polymorphic forms, with it being possible for particular modifications to be metastable. Unless stated to the contrary, the invention includes all such possible polymorphic forms. [00125] In some aspects, a structure of a compound can be represented by a formula: , which is understood to be equivalent to a formula: , wherein n is typically an integer. That is, Rn is understood to represent five independent substituents, Rn(a), Rn(b), Rn(c), Rn(d), Rn(e). By “independent substituents,” it is meant that each R substituent can be independently defined. For example, if in one instance Rn(a) is halogen, then Rn(b) is not necessarily halogen in that instance.

METHODS OF TREATING ACUTE RESPIRATORY DISTRESS SYNDROME (ARDS) IN A SUBJECT [00314] In one aspect, disclosed are methods treating acute respiratory distress syndrome (ARDS) in a subject in need thereof, the method comprising administering to the subject an effective amount of a disclosed compound, or a pharmaceutically acceptable salt thereof. Oxidative stress has been implicated as a major contributor to the pathogenesis of ARDS. In addition, aged mice with severe ARDS exhibited sustained upregulation of Nox4 and elevated ROS levels. As such, strategies that block the source of ROS production are more specific and effective in comparison to antioxidant strategies because the damage from highly reactive ROS molecules occur rapidly. [00315] Pulmonary endothelial cells (ECs) line the surface of the lung vasculature and are a critical regulator of vascular homeostasis. Located at the interface between the bloodstream and lung tissue, the endothelium serves as a barrier that regulates the influx of inflammatory cells and fluid into the interstitial space. A key pathological feature of ARDS is EC barrier disruption, which results in increased vascular permeability and inflammatory influx. The accumulation of inflammatory cells and protein-rich fluid into the alveolar space can result in alveolar filling, hypoxemia, and ultimately respiratory failure. Autopsy reports from COVID-19 patients revealed severe injury to lung ECs accompanied by significant inflammatory cell influx, and transcriptomics are consistent with EC dysregulation. Thus, it is theorized that a successful treatment for ARDS and COVID-19-associated ARDS would combat EC barrier dysfunction and inflammatory injury to circumvent pulmonary edema and reduce the risk of respiratory failure and death. [00316] Further, as noted above, a substantial body of evidence has implicated oxidative stress as a major contributor to the pathogenesis of ARDS. Numerous studies have demonstrated high levels of ROS in the lungs following acute lung injury (ALI) in animal models and in ARDS patients. Excessive ROS production has been shown to promote EC barrier dysfunction and increased vascular permeability, which amplifies tissue damage, capillary leak, and pulmonary edema. Elevated ROS levels in ARDS patients have also been linked to increased oxidatively modified proteins, which perpetuate barrier dysfunction and inflammation leading to lung injury. ARDS patients with greater levels of oxidative molecular damage have increased mortality rates; thus, minimizing oxidative stress is a promising approach to mitigate lung damage and improve survival. Unfortunately, despite the well-recognized role of oxidative stress in ARDS pathogenesis, the mechanisms that drive ARDS-associated redox imbalance are largely unknown. Thus, the ability to precisely target key mediators of this process has proved challenging. Moreover, although studies evaluating the effectiveness of antioxidants in animal models of ALI have been promising, clinical trials with antioxidant therapies have failed to reduce ARDS mortality. One potential explanation is that while antioxidants function to scavenge existing ROS (that has already been produced), they do not block the source of ROS production. Oxidants are highly reactive molecules, and once generated, can rapidly induce damage to cells and surrounding tissues and induce inflammatory responses. Thus, strategies that directly block the source of ROS production are likely to be more specific and effective in comparison to antioxidant strategies because the damage from highly reactive ROS molecules may occur rapidly. The proposed treatment method seeks to develop a novel therapeutic, which targets the critical pathological features of ARDS: excessive ROS production, barrier dysfunction, and inflammatory injury. [00317] As life expectancy continues to increase, there is a demographic shift toward a growing elderly population, including the U.S. elderly veteran population. ARDS disproportionately affects the elderly population; higher incidence and mortality are associated with advancing age. ARDS incidence is 16/100,000 persons for adolescents (15-19 years) vs. 306/100,000 among the elderly (75-84 years). ARDS mortality increases with age; 24% in adolescents vs.60% in elderly. ARDS mortality is 2-fold higher in patients >70 years vs. under 70, and elderly survivors have more difficulties recovering. Older age is also a significant risk factor for COVID-19-associated hospitalization, including the development of ARDS and progression from ARDS to death; 75% of hospitalized COVID-19 patients were ≥50 years. Of those who required intensive care, mechanical ventilation, or died, the median age was 63. COVID-19 mortality rate is also highly correlated to older age: 42% (80-89 years), 32% (70-79), 8% (60-69), and 2% (50-59). Importantly, the key pathologic features of ARDS (oxidative stress, barrier dysfunction, and inflammation – discussed above) are increased in elderly patients. Despite overwhelming epidemiologic studies that increased susceptibility and poor outcomes among the elderly, therapeutic targeting of age-dependent pathological mechanisms has yet to be explored in the development of ARDS treatments. This may explain the lack of successful treatment options for ARDS, which primarily afflicts the elderly. Data herein suggests that targeting age-dependent pathological mechanisms may be the key to improving survival outcomes for elderly ARDS patients. The proposed treatment method seeks to develop a novel therapeutic strategy to correct age-dependent dysfunction associated with severe ARDS in the elderly.

For any agents used in the methods described herein, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC50 (that is, the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Exemplary dosage amounts of a differentiation agent are at least from about 0.01 to 3000 mg per day, e.g., at least about 0.00001, 0.0001, 0.001, 0.01, 0.1, 1, 2, 5, 10, 25, 50, 100, 200, 500, 1000, 2000, or 3000 mg per kg per day, or more. [00379] The formulations and routes of administration can be tailored to the disease or disorder being treated, and for the specific human being treated. For example, a subject can receive a dose of the agent once or twice or more daily for one week, one month, six months, one year, or more. The treatment can continue indefinitely, such as throughout the lifetime of the human. Treatment can be administered at regular or irregular intervals (once every other day or twice per week), and the dosage and timing of the administration can be adjusted throughout the course of the treatment. The dosage can remain constant over the course of the treatment regimen, or it can be decreased or increased over the course of the treatment. [00380] In various aspects, the dosage facilitates an intended purpose for both prophylaxis and treatment without undesirable side effects, such as toxicity, irritation or allergic response. Although individual needs may vary, the determination of optimal ranges for effective amounts of formulations is within the skill of the art. Human doses can readily be extrapolated from animal studies (Katocs et al., (1990) Chapter 27 in Remington's Pharmaceutical Sciences, 18th Ed., Gennaro, ed., Mack Publishing Co., Easton, PA). In general, the dosage required to provide an effective amount of a formulation, which can be adjusted by one skilled in the art, will vary depending on several factors, including the age, health, physical condition, weight, type and extent of the disease or disorder of the recipient, frequency of treatment, the nature of concurrent therapy, if required, and the nature and scope of the desired effect(s) (Nies et al., (1996) Chapter 3, In: Goodman & Gilman's The Pharmacological Basis of Therapeutics, 9th Ed., Hardman et al., eds., McGraw-Hill, New York, NY). b. ROUTES OF ADMINISTRATION [00381] Also provided are routes of administering the disclosed compounds and compositions. The compounds and compositions of the present invention can be administered by direct therapy using systemic administration and/or local administration. In various aspects, the route of administration can be determined by a patient's health care provider or clinician, for example following an evaluation of the patient. In various aspects, an individual patient's therapy may be customized, e.g., the type of agent used, the routes of administration, and the frequency of administration can be personalized. Alternatively, therapy may be performed using a standard course of treatment, e.g., using pre-selected agents and pre-selected routes of administration and frequency of administration. [00382] Systemic routes of administration can include, but are not limited to, parenteral routes of administration, e.g., intravenous injection, intramuscular injection, and intraperitoneal injection; enteral routes of administration e.g., administration by the oral route, lozenges, compressed tablets, pills, tablets, capsules, drops (e.g., ear drops), syrups, suspensions and emulsions; rectal administration, e.g., a rectal suppository or enema; a vaginal suppository; a urethral suppository; transdermal routes of administration; and inhalation (e.g., nasal sprays). [00383] In various aspects, the modes of administration described above may be combined in any order. J.

3. DEVELOPMENT OF ARDS THERAPEUTIC STRATEGIES [00422] A Novel 2-Hit Pre-Clinical Aging Murine Model of Severe ARDS Better Reccapitulates the Clinical Features of ARDS in Elderly Patients. Pre-clinical animal models that more accurately reproduce the clinical features of ARDS are critical to better understanding pathogenesis and developing therapeutic interventions. A key limitation is the overwhelming utilization of young animals to evaluate the pathogenesis and therapeutic interventions of this age-related disease. A novel 2-hit pre-clinical aging murine model of severe ARDS was developed previously (Palumbo et al. (2017) American Journal of Physiology-Lung Cellular and Molecular Physiology 312.3: L297-L308). In this model, aged (18 month) mice are subjected to combined exposure to both LPS and VILI (FIG.1A). It was shown that, compared to young (2m) cohorts, only aged mice develop severe ARDS; demonstrated by significantly increased: lung injury score (FIG.1B), vascular permeability (bronchoalveolar lavage protein, cellular, neutrophil, and albumin influx), oxidative damage, and mortality. These findings support the concept that synergistic lung inflammatory and injury responses are acquired with advanced age. Overall, this 2-hit pre-clinical aging model of severe ARDS more accurately recapitulates the clinical features of ARDS in elderly patients (regardless of etiology). This model is in line with elderly patients at risk for ARDS and provides the ability to implement more clinically relevant therapeutic testing protocols. [00423] Senescent ECs Exhibit Defective Barrier-Regulatory Responses. The increased presence of senescent cells at sites of age-associated pathologies supports a role for senescence in the pathogenesis (Vasile E, et al. (2001) FASEB 15(2):458-66). The impact of senescence in EC barrier-regulatory responses was evaluated using an in vitro cellular model of replicative senescence using characterized human ECs characterized. In response to insult, senescent cells exhibit significantly increased permeability (FIG.2B), as compared to control “young” ECs (FIG.2A). Without wishing to be bound by theory, these studies indicate that EC senescence leads to impaired barrier function. [00424] Nox4: An ROS-Generating Enzyme that Mediates EC Permeability. Numerous studies have demonstrated that excessive ROS production plays a major role in EC barrier dysfunction resulting in pulmonary edema. It has been demonstrated that although both young and senescent ECs generate ROS in response to insult, senescent ECs with defective barrier- regulatory responses generated significantly greater ROS levels compared to young ECs (FIG. 3A) (Palumbo et al. (2017) American Journal of Physiology-Lung Cellular and Molecular Physiology 312.3: L297-L308). [00425] The NADPH oxidase (Nox) enzymes are an evolutionarily conserved gene family linked to host defense mechanisms. The only known role of Nox enzymes is the production of ROS, which is important for cellular homeostasis and stress-induced repair-responses. NADPH oxidase-4 (Nox4) is a constitutively active enzyme, which specifically generates H2O2, a relatively stable oxidant compared to other ROS types. Nox4 is the most abundantly expressed Nox isoform in ECs, and Nox4 is the primary enzymatic source of ROS in ECs. It has been demonstrated that Nox4-dependent ROS mediates EC permeability. Importantly, in response to insult, expression levels of other Nox isoforms remained unchanged (only Nox4 was increased). These findings have been validated further confirming the Nox4-specific role in mediating EC permeability (ruling out the role of other Nox isoforms). Further, a number of stimuli (ex. LPS and P. aeruginosa) have been shown to induce Nox4-dependent ROS, which mediates increased permeability responses in various types of ECs and promotes pro-inflammatory responses. It has been demonstrated that in response to insult, senescent ECs generate excessive ROS levels due to persistently elevated Nox4 expression (FIG.3A and FIG.3B), whereas control ECs exhibit rapid and transient expression of Nox4 with lower ROS levels (FIG.3A and FIG.3B). It has been demonstrated that targeting Nox4 in senescent ECs attenuated ROS production and restored barrier function. Nox4 has also been shown to mediate senescence; Nox4 overexpression increased ROS production and induced EC senescence, whereas Nox4 knockdown inhibited the induction of EC senescence. Overall, Nox4-dependent ROS plays a critical in mediating EC barrier regulatory responses, and aberrant/sustained upregulation of Nox4 in senescent ECs promotes persistently elevated ROS levels resulting in exacerbated permeability and inflammatory responses. [00426] Aged Mice with Severe ARDS Exhibit Sustained Upregulation of Nox4 and Elevated ROS. It was previously demonstrated that aged mice with severe ARDS (FIG.1B) exhibited significantly elevated Nox4 protein levels in the lungs, which corresponded with increased ROS levels in lung BAL (FIG.4) (Palumbo et al. (2017) American Journal of Physiology-Lung Cellular and Molecular Physiology 312.3: L297-L308). In contrast, young/injured mice that demonstrated mild injury exhibited only a modest increase in Nox4 and had significantly lower BAL/ROS levels than aged/injured mice (FIG.4). These results demonstrate an age-dependent divergent induction of Nox4 in the lungs following ALI. [00427] Novel Age-Dependent Mechanism of Nox4 Dysregulation. Although Nox4 is primarily known to be regulated at the transcriptional level, It has been demonstrated that Nox4 expression can be rapidly induced (within 5 min) in both young control ECs and senescent ECs. A novel post-translational mechanism has been established by which expression of Nox4 can be rapidly altered in ECs (via the proteasome-ubiquitin system). Importantly, in young ECs (with intact permeability responses) this rapid increase in Nox4 expression returned to baseline levels within 1h. In contrast, senescent ECs exhibit deficient ubiquitination of Nox4, which promotes its sustained expression and excessive ROS production. Without wishing to be bound by theory, these studies provide novel mechanistic insight that may in part explain the persistent upregulation of Nox4 following acute insult/injury in the context of aging, and further validate the rationale to develop ARDS therapeutic strategies that aim to correct age-dependent Nox4 dysfunction. [00428] Selective Nox4 Inhibitors Have Not Been Successfully Developed. There are no commercially available Nox4 inhibitors. Nox4 drug development has proven challenging for several reasons. The crystal structure of Nox4 is unknown, which precludes traditional rational drug design approaches. Screening methods for Nox inhibitors typically utilize ROS detection- based screening assays that have limited specificity. Thus, it may be difficult to discern whether a putative inhibitor is acting directly on Nox versus regulation of upstream signaling pathway(s). Accordingly, one study reported that of >350 “Nox inhibitors” described, a majority of these did not directly block Nox enzymatic activity, but rather showed interference with upstream signaling pathways or demonstrated antioxidant activity. An additional challenge to the field is reports of putative “Nox inhibitors,” which have been subsequently challenged and disproven. [00429] The most well-studied putative “Nox1/4 inhibitor” is Setanaxib (also known as GKT137831), originally developed by Genkyotex (Geneva, Switzerland) and now being developed by Calliditas Therapeutics. However, a recent in-depth evaluation of putative Nox inhibitors demonstrated that “GKT136901 is inactive as Nox inhibitor, but rather interferes with peroxidase-dependent assays” (Augsburger et. al. (2019) Redox Biol 26:101272). Setanaxib showed significant inhibitory activity in the presence of H2O2 alone using a cell-free assay system (Augsburger et. al. (2019) Redox Biol 26:101272), suggesting it acts as an anti-oxidant rather than via direct Nox4 inhibition. Recent data further validate these findings: in a cell-free assay with exogenous H2O2, Setanaxib showed 63% inhibition at 10mM (Fig.5A), and 100% inhibition at higher concentrations >30mM. Although Setanaxib remains marketed as a Nox1/4 inhibitor, it has been definitively shown that its mechanism of action is not via direct Nox inhibition. [00430] APX-115 is a “putative Nox1,2,4 inhibitor” (Aptabio Therapeutics Inc) that is currently in a clinical trial for Type 2 diabetic nephropathy. Although this candidate has been evaluated in pre-clinical efficacy studies with animal models, it is important to note that its characterization as a “Nox inhibitor” is limited to only one published report. Further, the rigor of published characterization studies with APX-115 is below currently accepted standards. Shortcomings of APX-115 characterization include: (1) Lucigenin was used for ROS detection, which detects O2 (not H2O2, the primary ROS produced by Nox4). Further, NADPH + lucigenin generates a bioluminescent signal, which is not Nox dependent; caution is advised for the use of lucigenin for ROS detection. (2) False-positive screening for H2O2 scavenger activity also utilized Lucigenin (which only detects O2). Further, 1 mM H2O2 was evaluated in this assay; this concentration is likely to denature the system such that results are not reliable (5-10 µM H2O2 is appropriate for such assays). (3) ROS generation was evaluated by dichlorodihydrofluorescein (DCF); however, DCF is photoactivated and known to be artifact prone. (4) The Drosophila membrane assay utilized lacks validation; no data is provided to confirm Nox expression and no controls were used. (5) Studies lack the addition of subunits for Nox1 and Nox2, which are essential to have a functional ROS generating Nox1 and 2 membrane assays. In summary, although APX-115 and Setanaxib might be interesting non-toxic pharmacological agents, their Nox inhibitory activity has either been disproven (Setanaxib) or is not convincing (APX-115). Current data demonstrate that APX-115 is an antioxidant: in a cell-free assay with exogenous H2O2, APX- 115 showed 56% inhibition at 10 μM, and 100% inhibition at higher concentrations >30 μM (FIG.5A). [00431] GLX351322: is a putative Nox inhibitor developed by Glucox Biotech, which was initially identified via a high-throughput approach using a Nox4 overexpressing cell line and an Amplex Red assay (similar to our primary screening assay). This candidate is still in pre-clinical development and has not reached clinical trials. Pre-clinical studies have evaluated GLX351322 as a therapeutic strategy for type 2 diabetes. However, similar to APX-115, published studies are primarily focused on its therapeutic effects and rigorous validation studies for its potency and selectivity for Nox4 are lacking. Data indicates that GLX351322 has toxic effects; treatment 10mM led to 66% cell death, as compared to vehicle (Fig.5B). This calls into question the validity of this candidate, as decreased cell number resulting from cell death is a false-positive result in the primary screen. [00432] Diphenylene iodonium (DPI) remains the only well-validated pan-Nox inhibitor; however, drawbacks including lack of specificity individual, off-target inhibition of other ROS- producing systems, irreversible binding and toxicity in vivo have prevented its therapeutic development of this non-drug-like molecule. Nonetheless DPI remains a powerful tool for Nox therapeutic development programs and will be used as a positive control in our proposed studies. [00433] In summary, no bona fide Nox inhibitors are clinically available. Importantly, Setanaxib, APX-115, and GLX351322 did not pass the false-positive screening at the earliest stage of our screening pipeline, which is required for any of our candidates to advance. Although APX-115 and Setanaxib might be interesting non-toxic pharmacological agents (both currently in clinical trials), their Nox inhibitory activity has either been disproven or is not convincing. The observed protective effects of these candidates reported in pre-clinical in vivo studies do not stem from direct inhibition of Nox, but rather from a non-specific redox mechanism and/or downstream effects on Nox4 activity. A bona fide Nox4 inhibitor needs to fulfill several criteria: limited antioxidant activity, lack of effect on other sources of ROS upstream of Nox4 signaling, demonstrated direct inhibition of Nox4 activity, and high selectivity for Nox4. The development of novel biochemical assays and progress in other therapeutic Nox programs will be monitored in order to maintain the highest standards of rigor and reproducibility. [00434] Other putative Nox inhibitors failed the screening pipeline. Referring to FIG.5A and FIG.5B, APX-115, Setanaxib, and GLX exemplified the failed false-positive screening of the putative Nox4 inhibitors. FIG.5A shows compounds at (10mM), Vehicle (DMSO), or Catalase (750U/mL; positive control for antioxidant activity) were incubated with H2O2 (5µM) for 1h. H2O2 was assessed by ROS-Glo Amplex Red (HRP-dependent assay); these data demonstrate that other putative Nox inhibitors act as antioxidants. FIG.5B shows data of HEK cells stably transfected to overexpress Nox4 (HEK-Nox4 cells) were treated with compounds (10µM), vehicle control (DMSO), or digitonin (positive control cell death) and incubated for 1h. Cellular viability was evaluated by CellTiter-Glo® Assay. These data demonstrate that GLX treatment leads to significant cell death. 4. PRELIMINARY STUDIES a. NOX4 TARGET VALIDATION [00435] Previous studies have demonstrated that Nox4 mediates EC barrier responses, and that Nox4 is upregulated in senescent ECs. Microarray data further corroborated these findings at the transcriptional level (Table 2). Importantly, no other Nox isoforms are upregulated. Overall, these data further support a Nox4-specific role in mediating EC permeability. TABLE 2. b. AGED EC-TARGETED NOX4 KO MICE DEMONSTRATE STRIKING PROTECTION FROM ALI [00436] Although several studies have demonstrated in vivo proof-of-concept for systemic targeting of Nox4-mediated barrier dysfunction, evidence for selective targeting of Nox4 specifically in ECs in vivo has not been performed previously due to the lack of available research tools. Further, genetic targeting of Nox4 in age-dependent severe pre-clinical ARDS has not been evaluated previously. In a mouse model of brain ischemia, EC-targeted genetic ablation of Nox4 led to significant protection from blood-brain barrier breakdown, supporting an EC- specific role for Nox4 in mediating permeability responses in vivo. Another study demonstrated that EC-specific targeting of Nox activation (via PECAM-conjugated liposome containing MJ33, an indirect inhibitor of Nox activity) resulted in greater protection from ALI, as compared to systemic delivery. In order to more specifically evaluate the role of EC-Nox4 in ALI in vivo, particularly in the context of aging, endothelial targeted Nox4 knockout (Nox4-eKO) mice were developed (FIG.6A), and mice were aged to 18m. To confirm EC-Nox4 knockdown in vivo, ECs were isolated from wild-type (WT) and Nox4-eKO mice via FACS. Indeed, ECs isolated from Nox4-eKO mice demonstrated significant knockdown of Nox4, as compared to WT isolated ECs (FIG.6B). Young (2m) and aged (18m) WT and Nox4-eKO mice were then subjected to ALI (LPS via IT delivery). Although preliminary data suggested that young Nox4- eKO mice exhibit some protection from ALI, only aged Nox4-eKO mice exhibited striking protection from ALI, as demonstrated by decreased lung BAL cells (FIG.6C), decreased BAL ROS levels (FIG.6D), decreased BAL protein (FIG.6E), and decreased lung albumin (FIG. 6F). Overall, these studies support the concept that specifically targeting mechanisms that become defective in aging (ex. persistently elevated Nox4/ROS) offers the most significant therapeutic benefit, and may be the key to improving outcomes for elderly ARDS patients. [00437] Referring to FIG.6A-F, validates that aged Nox4-eKO mice demonstrate striking protection from ALI. FIG.6A shows Nox4-eKO mice were generated by crossing Nox4 floxed mouse (gift from Dr. Sadoshima, Rutgers University) with EC specific promoter-driven Cre (EC- targeted Cre) mouse (Jackson Laboratory); confirmed by genotyping. FIG.6B shows data of lung ECs from WT and Nox4-eKO mice were isolated via FACS and evaluated for Nox4 expression via WB. FIG.6C-F show young and aged mice were subjected to intratracheal instillation of LPS (0.2mg/kg) via IT delivery for 24h. Severity of ALI assessed by total BAL cells (FIG.6C), BAL H2O2 (FIG.6D), BAL protein (FIG.6E), and BAL albumin (FIG.6F). Values shown are injured mice compared to respective uninjured control.

IDENTIFICATION OF NOVEL NOX4 SMALL-MOLECULE INHIBITOR CANDIDATES FOR FIBROSIS INDICATIONS VIA ORAL DELIVERY [00438] Previous studies demonstrated feasibility of successful pre-clinical development of Nox4 inhibitors. A high-throughput screening (HTS) approach was employed to screen for Nox4 inhibitor candidates, utilizing HEK293 cells that stably over-express Nox4 (HEK/Nox4 cells) which generate high levels of Nox4-dependent H2O2.30,000 compounds were screened, which led to the identification of “hits” which were subjected to false-positive screening; those that passed served as a starting point for medicinal chemistry efforts. A putative lead candidate (UANOX48) emerged. See Table 1. [00439] UANOX48 has a low molecular weight (384.4 g/mole) and a relatively high solid-to-liquid melting phase transition (Tonset 89.72˚C, Tpeak 92.3°C), indicating high stability at both room and body temperatures (32-37°C); this is important from a pharmaceutical standpoint, as these data indicate high stability at drug manufacturing/processing and delivery temperatures. UANOX48 passed false-positive screening: demonstrated no scavenger activity (does not act as an antioxidant) (FIG.7A and FIG.7B), does not interfere with assay reagents (FIG.7A), and has no effect on cellular viability (FIG.7C). Predicted docking/binding simulations were also performed on the two enantiomers of UANOX48 using Autodock Vina (J Comput Chem.2010, 31(2):455-61. doi: 10.1002/jcc.21334. PMID: 19499576). For this docking study, a homology model of Nox4 was used with the binding orientation of UANOX048 as a reference. It was observed that R- and S-enantiomers of UANOX48 adopt identical docked poses having the same dock score (-9.0 kcal/mol), with their methyl moiety oriented in opposite directions in regions where they form no interaction with the active site residues. This in silico observation strongly indicates direct binding with high binding affinity and a lack of preference for either enantiomer. [00440] UANOX48 demonstrated high selectivity for Nox4 over Nox2 or xanthine oxidase (Nox-independent ROS generation) (FIG.7D). In vitro absorption, distribution, metabolism, and excretion (ADME) indicate an acceptable profile, with low lipophilicity (calculated logD = 3.85) and high Caco-2 permeability no efflux pump susceptibility (54.6 ×10cm/sec). The inducibility of Nox4-dependent H2O2 by TGF-β1 is a highly specific and unique function of Nox4. This unique feature of Nox4 was exploited in the screening cascade. In human lung fibroblasts, treatment with UANOX048 inhibited TGF-β1-induced H2O2 production, which blocked induction of pro-fibrotic myofibroblast phenotypes, including myofibroblast differentiation and collagen production. [00441] Referring to FIG.7A-D, shows assays associated with identification of a novel Nox4 inhibitor. FIG.7A-C show results for false-positive screening: UANOX48 (10 µM), Vehicle (DMSO), or Catalase (750U/mL; positive control for scavenger activity) were incubated with H2O2 (5 µM) for 1h. Scavenger activity of H2O2 was assessed by ROS-Glo (HRP- independent assay) (FIG.7A) and Amplex Red (HRP-dependent assay) (FIG.7B). FIG.7C shows HEK cells stably transfected to overexpress Nox4 (HEK-Nox4 cells) were treated with UANOX48 (10 µM), vehicle control (DMSO), or digitonin (positive control cell death) and incubated for 1h. Cellular viability was evaluated by CellTiter-Glo® Assay. FIG.7D shows selectivity assay data: IC50 evaluation was performed in cell-based assays. Nox4: HEK-Nox4 cells were treated with varying concentrations of UANOX48 or vehicle (DMSO) and incubated for 1h. H2O2 production was evaluated by Amplex Red assay. Nox2: RAW 264.7 cells were stimulated with PMA to induce Nox2 activity. Xanthine oxidase (XO): XO was evaluated by XO activity assay. All values represent means ± SEM (n=3-6); *p<0.05; ***p<0.001; using students t-test or one-way ANOVA multiple comparisons with a Tukey’s post-test. [00442] In lung myofibroblasts isolated from IPF patients, treatment with UANOX48 promoted the reversal of established pro-fibrotic myofibroblast phenotypes: inhibited H2O2 production (IC5025.7 nM) (FIG.8A), and collagen production (FIG.8B). Importantly, in vivo efficacy was evaluated in an aging model of persistent lung fibrosis; treatment with UANOX48 promotes the reversal of age-dependent established fibrosis, which resulted in improved lung function. In vivo efficacy was demonstrated for UANOX48 for inhibiting cardiac fibrosis, which led to improvement in cardiac function. [00443] Referring to FIG.8A and FIG.8B, Nox4 inhibition reverses established pro- fibrotic phenotypes in human IPF lung myofibroblasts. FIG.8A shows myofibroblasts isolated from the lungs of IPF patients treated with UANOX48 (10 µM or as indicated) or vehicle (DMSO). H2O2 levels were evaluated at 24h by Amplex Red assay. FIG.8B shows collagen levels determined by quantitative Sircol assay (n=3-6); *p<0.05;**p<0.01; using one-way ANOVA multiple comparisons with a Tukey’s post-test or Student’s two-tailed t-test to compare the means between two groups. d. TARGETING NOX4-DEPENDENT REDOX IMBALANCE AS A THERAPEUTIC APPROACH FOR ARDS [00444] UANOX48 was utilized to demonstrate proof-of-concept for targeting Nox4 in an animal model of ARDS. Treatment with UANOX48 led to reduced ROS levels in senescent ECs (FIG.9A) and increased proliferation of non-senescent ECs (FIG.9B). [00445] The PK profile and lung distribution of UANOX048 via IV delivery was evaluated in mice; half-life (t1/2) 3h (plasma), and 2.9h (lung). The efficacy of UANOX048 was evaluated in a murine model of ALI. Mice were pre-treated with inhibitor or vehicle via IV administration and subjected to ALI. Mice treated with UANOX48 demonstrated reduced blood ROS levels (FIG.9C) and significant protection from ALI including significantly reduced lung albumin (FIG.9D) and inflammation inflammatory (specifically decreased neutrophil influx) (FIG.9E-G)). These results demonstrate efficacy and provide rationale for the continued development of Nox4 inhibitors for ARDS. [00446] Referring to FIG.9A-G, Nox4 inhibitors protect from pre-clinical ARDS. FIG. 9A shows senescent ECs were treated with Nox4 inhibitor (20 µM), vehicle (DMSO), or DPI (10 µM) for 2h; H2O2 was assesed by Amplex Red. FIG.9B shows ECs were treated with Nox4 inhibitor (0.1 nM) or DMSO and incubated for 5 days. Proliferation was evaluated by Cell Viability Assay. (n = 3-5; *p < 0.05, ****p < 0.0001) FIG.9C-G show young (2m) C57BL/6 mice were treated with UANOX48 (50 mg/kg) or vehicle via IV followed by IT instillation of LPS (0.2 mg/kg). (FIG.9C) 4h post-injury and plasma H2O2 was evaluated by Amplex red. Severity of ALI was assessed at 24h post-injury by lung albumin (FIG.9D), total BAL cells (FIG.9E), neutrophil influx (FIG.9F), and histopathology (FIG.9G). (n = 3-6 mice/group; *p<0.05, **p<0.01, ***p<0.001, ns = not statistically significant). e. NOVEL NOX4 INHIBITOR CANDIDATES IDENTIFIED FOR IV DELIVERY [00447] The studies with UANOX48 showcase the development of Nox4 small molecule inhibitors and the performance of pre-clinical efficacy studies, which inform and strongly support the experimental plan detailed herein. Although these studies provide proof-of-concept for the continued pre-clinical development of Nox4 inhibitors for ARDS, UANOX48 is not an ideal candidate for IV delivery; it has relatively low water solubility (high solubility is a key metric for IV delivered drugs) and higher clearance (Clint >200 µL/min/mg) in human and mouse liver microsomes as well as oral or IV dosing in rodents. The ideal Nox4 inhibitor should meet optimal physicochemical selection criteria for IV delivery leads: cLogP = 3-4, polar surface area (PSA) = 45-70, water solubility at pH 7.4 = >10 µM, mol weight <500, non-ionic molecule, and potency similar to UANOX48. Two representative candidates are shown in FIG.10. [00448] These combined efforts led to the identification of Nox4 inhibitor candidates (APV235197A, APV235973A, UANOX108, UANOX107; FIG.10 – two of these are shown) that meet optimal physiochemical criteria for IV delivery and are predicted to have highly favorable profiles for IV delivery in humans. Without wishing to be bound by theory, these candidates will be the starting point for medicinal chemistry efforts proposed to further optimize and expand the chemical space around these candidates. f. DEVELOPMENT OF NOVEL LUNG-TARGETING NOX4 INHIBITORS FOR ENHANCED LUNG DISTRIBUTION [00449] Macrolides are a class of antibiotics, which commonly used to treat various respiratory conditions. Their use in respiratory indications is advantageous due to a unique property of macrolide-based compounds: they have a high affinity for the lung and are able to effectively penetrate lung tissue. Significant distribution of macrolides in the lung occurs within 2h of IV delivery, and sustained lung levels are detectable for up to 8.5 days. Pre-clinical and clinical data have demonstrated that 24h after systemic administration, concentrations of macrolides are 400-800 times greater in the alveolar compared to serum levels. Treatment with macrolide antibiotics, specifically azithromycin, is associated with improved outcomes in the ALI/ARDS arena. In patients with ALI, treatment with azithromycin led to increased survival and decreased time to successful discontinuation of mechanical ventilation. Further, a retrospective cohort evaluation of hospitalized patients with sepsis-associated ARDS assessed the impact of azithromycin on clinical outcomes; azithromycin treatment was associated with decreased mortality and ventilator dependency in patients with sepsis-associated ARDS. [00450] A macrocycle is a molecule that contains a cyclic framework of >12 atoms that can encapsulate drugs, thereby being used as a drug delivery vehicle, particularly to exploit a key property of macrolides: lung-targeting. It has been shown that the tissue accumulation property of macrocycle is tolerant of changes to their key moieties, resulting in compounds and nano- conjugates, which accumulate in the lung. This class of bioconjugate serves as an effective platform for intracellular drug delivery in the context of pulmonary disease and is highly amenable to IV delivery (vs. other delivery routes). A significant number of macrocycle-based IV drugs are currently on the market, as they are well-tolerated, with no serious adverse events reported in clinical trials. Treprostinil and Macitentan are two examples of FDA-approved macrocycle drugs specifically utilized for pulmonary indications (pulmonary hypertension). [00451] A Lung-Targeting Nox4 inhibitor (LT-Nox4i) series was developed in an effort to improve distribution and concentration of candidate inhibitors within the lung. We utilized a structure-based design tool to develop several macrocycle-based Nox4 inhibitors and evaluate docking simulations in silico (FIG.11A and FIG.11B). Docking simulations predicted that compared to parent Nox4 inhibitors, LT-Nox4i’s designed demonstrated either similar binding affinity to Nox4 (-8.6--9 kcal/mol) and some LT-Nox4i’s demonstrated significantly increased binding affinity for Nox4 (up to -9.7--10.4 kcal/mol) vs parent inhibitor alone; these data suggest that the medicinal chemistry features of LT-Nox4i’s may exhibit improved binding to Nox4. Artificial intelligence (AI) platform was utilized to perform blinded screening of two LT-Nox4i structures; as compared to 50 of our top parent Nox4 inhibitors, LT-Nox4i’s were predicted to have up to ~30-fold increased distribution within the lungs, as compared to parent Nox4 inhibitors alone (Table 3). TABLE 3. [00452] Further, docking simulations predicted significantly increased binding affinity for Nox4 for macrocycle-Nox4 inhibitors (up to -10.4 kcal/mol) vs parent inhibitor alone (-8.6 kcal/mol) (Table 4). Macrocycles are an ideal vehicle to develop lung-targeted Nox4 inhibitors intended for IV delivery. Without being bound by theory, this directed approach will increase availability of Nox4 inhibitor within the lungs and will increase efficacy at significantly lower concentrations while reducing the toxicity risk. TABLE 4. [00453] Based on promising in silico and AI predictive data, additional macrocycle-based LT-Nox4i for continued screening were prepared. Given that azithromycin treatment alone has already demonstrated positive outcomes in ALI/ARDS patients, azithromycin was selected as the macrolide-based linker to attach to Nox4 inhibitors. Importantly, azithromycin alone showed no potency for inhibiting Nox4-dependent ROS, while Compound 7 LT-Nox4i-1 (Nox4 inhibitor attached to azithromycin) showed nearly identical potency for Nox4/ROS inhibition compared to parent Nox4 inhibitors compounds 1 and 2 (FIG.12A). The efficacy of LT-Nox4i analogs were also evaluated for inhibiting Nox4-dependent ROS in senescent ECs; LT-Nox4i’s also showed similar potency to parent Nox4i’s for inhibiting ROS in senescent ECs (FIG.12B). [00454] Referring to FIG.12A and FIG.12B, comparisons of IC50 evaluation of LT- Nox4i vs parent Nox4 inhibitors or macrolide (azithromycin) alone are shown. FIG.12A shows stable Nox4 overexpressing HEK (HEK-Nox4) cells were treated with varying concentrations of azithromycin (macrolide alone), parent Nox4 inhibitors (shown as compounds 1 and 2), or Lung- Targeting-Nox4 inhibitor (LT-Nox4i-1; shown as compound 7 in graph). and incubated for 1h in HEK-Nox4 cells. H2O2 production was evaluated by Amplex Red assay. Values = means ±SEM (n=3). Lung-Targeting-Nox4 inhibitors (LT-Nox4i-1; shown as compound 7 or LT- Nox4i-7; shown as compound 13 in graph) vs parent Nox inhibitors (compounds 3 and 6). These data demonstrate that adding the linker does not interfere with Nox4 inhibitory activity. [00455] Lung-targeting approach in vivo, was to be evaluated by performing PK studies with parent Nox4 inhibitor versus LT-Nox4i. The LT-Nox4i demonstrated significantly increased maximal concentrations (Cmax) within the lung (up to ~65-fold higher than parent) which remain elevated in the lungs even at 24h post-administration (vs. parent which drop to zero within the lung within ~1h pos-administration (FIG.13A-C). This is likely also due to the fact that LT-Nox4i demonstrated significantly decreased clearance within the lung vs. parent Nox4 inhibitors (FIG.13B). The area under the curve (AUC) gives insight into the extent of drug exposure and its clearance rate. Importantly, compared to parent Nox4 inhibitors the LT-Nox4i demonstrated significantly increased AUC levels in the lung (up to ~1,000-fold increased; FIG. 13B) and significantly decreased plasma AUC levels (FIG.13A); these data indicate that LT- Nox4i exhibits a tremendous improvement in lung exposure accompanied by reduced systemic exposure in vivo. [00456] Referring to FIG.13A-C, Lung-targeting Nox4 inhibitor demonstrated significantly elevated concentrations within the lung in vivo vs. parent Nox4 inhibitor. C57/Bl6 male mice (2m) were administered Lung-targeting Nox4 inhibitor (LT-Nox4i-1) or parent Nox4 inhibitors via IV delivery (1mg/kg). Plasma and lung tissues were harvested at various time points following administration and assessed by LC-MS/MS. Analysis was performed using Pksolver 2.0 and one-compartment model. Blood plasma PK (FIG.13A) and lung PK (FIG.13B and FIG.13C) parameters are shown. [00457] LPS (1mg/kg) was administered to mice followed by treatment vehicle, parent Nox4i, or LT-Nox4i-1 (5.7mg/kg;days 0-3) and endpoints were assessed 4 days post-injury. Treatment with LT-Nox4i-1 significantly reduced lung BAL cells (FIG.15). In contrast, parent Nox4i showed no efficacy. To evaluate this lung-targeting approach in vivo, we performed PK studies with IV delivery of LT-Nox4i-1 vs. parent Nox4 inhibitor (UANOX48) via IV and inhaled delivery. The area under the curve (AUC) is used to assess the extent of drug exposure (AUC accounts for Cmax, t1/2, and clearance rate). Importantly, compared to parent Nox4i at the same dose (1mg/kg), IV delivery of LT-Nox4i-1 resulted in 40-fold increased AUC levels in the lung (this represents a 4,000% increase) (FIG.16B and Table 6). Even when compared to inhaled delivery of parent Nox4i at 10x the dose (10mg/kg), IV delivery of LT-Nox4i-1 (1mg/kg) resulted in 11-fold increased lung AUC levels (FIG.16B and Table 6). Further, LT-Nox4i-1 drug concentration remained elevated in the lungs 24 hours post administration, whereas concentrations of parent Nox4i (via both IV and inhaled delivery) were negligible within 1h post administration (FIG.16A and Table 5). Finally, compared to parent Nox4i, LT-Nox4i-1 resulted in a 50% decrease in plasma AUC levels (FIG.16A and Table 5), indicating significantly reduced systemic exposure and decreased toxicity risk. In summary, this directed approach dramatically improves drug exposure within the lungs and simultaneously decrease systemic exposure, which reduce the potential for off-target effects and/or toxicity. TABLE 5. TABLE 6. [00458] Referring to FIG.17A-D, FIG.17A demonstrates that LT-Nox4i-1 inhibits ROS production in a stable cell line overexpressing Nox4. FIG.17B demonstrates that LT-Nox4i-1 does not induce cell death in a viability assay (Digitonin is a positive control for cell death). FIG.17C demonstrates that LT-Nox4i-1 does not inhibit Nox-independent ROS production (via xanthine oxidase). FIG.17D demonstrates that LT-Nox4i-1 shows no antioxidant activity in a cell-free assay with exogenous ROS (catalase is a positive control for antioxidant activity). [00459] Overall, these data suggest that macrocycles are an ideal vehicle to develop lung- targeted Nox4 inhibitors intended for IV delivery. The proposed studies will exploit a well- known property of macrocycles: they “home” to the lung following systemic delivery. This directed approach will increase availability of Nox4 inhibitor within the lungs and will increase efficacy at significantly lower concentrations while reducing the toxicity risk. Without wishing to be bound by theory, these linkers can be attached to a variety of different Nox4 inhibitors as further described herein. 5. LINKING EXCESSIVE NOX4-DERIVED ROS AND AGE-RELATED DISEASE [00460] The only known physiologic role of Nox4 is ROS production; importantly, redox- signaling events depend on spatially confined and tightly regulated Nox4-dependent ROS production. In contrast, persistent expression of Nox4 and sustained ROS production leads to oxidative stress (that is no longer compartmentalized) and detrimental effects. Preliminary data and a growing body of evidence supports a link between excessive Nox4-derived ROS and numerous age-related diseases. Nox4 represents an “antagonistically pleiotropic” enzyme – it confers a reproductive advantage early in life but can have detrimental effects in late life (during post-reproductive age). This makes Nox4 an attractive target from a drug targeting perspective. Further, it is important to note that Nox4 knockout mice are viable with no appreciable phenotype in the unstressed (uninjured) state; suggesting lower risk for toxicity or off-target effects from Nox4 inhibition in unaffected tissues. [00461] Extensive epidemiological data demonstrates that susceptibility, severity, hospitalization, and mortality from ARDS is significantly higher in the elderly population. It is therefore hypothesized that therapeutic strategies targeting age-associated pathologic mechanisms offer the greatest potential for developing successful ARDS treatments; targeting the persistent upregulation of Nox4 (a major source of excessive oxidant generation) represents one plausible strategy. Published studies have identified novel age-dependent mechanisms of Nox4 dysregulation, leading to excessive ROS production and increased severity and mortality of ARDS in aging. Collectively, these studies suggest that targeting Nox4 in aging provides the greatest therapeutic benefit. It is important to note that Nox inhibitors are not clinically available, but substantial progress has been made recently in developing Nox4 inhibitors for oral delivery. However, ARDS patients often require mechanical ventilation for life support, where oral delivery is not optimal. As IV administration is the ideal delivery route for critically ill patients, a key objective is to optimize Nox4 inhibitors for IV delivery as a novel therapy to reduce susceptibility and mortality from age-dependent severe ARDS. 6. RESEARCH DESIGN AND METHODS a. DIRECTED MEDICINAL CHEMISTRY TO EXPAND LUNG-TARGETING NOX4 INHIBITOR SERIES AND SCREEN FOR NOX4 INHIBITION [00462] UANOX48 was used to demonstrate proof-of-concept for targeting Nox4 in an animal model of ARDS. However, UANOX48 is not ideally suited for subsequent clinical development for ARDS primarily due to poor bioavailability within the lung; this is largely attributed to poor metabolic stability (high liver microsomal clearance, 349 μL/min/mg) and relatively high logD (4.05). [00463] To overcome this major liability, lung-targeting Nox4-inhibitors (LT-Nox4is) were developed using a macrocycle-based approach; proof-of-concept that for the development of LT-Nox4is using a macrocycle-based approach was demonstrated (FIG.13A-C). The initial data demonstrate that compared to parent Nox4 inhibitor alone, this approach results in significantly increased drug exposure (>1,000-fold) within the lung, with significantly reduced systemic exposure. This directed approach dramatically boosts bioavailability of Nox4 inhibitor within the lung while reducing the risk of systemic toxicity. During proof-of-concept studies, several synthesized LT-Nox4i candidates were prepared. It was found that some lung-targeting Nox4-inhibitors have identical or somewhat improved potency as compared to parent Nox4 inhibitor alone (FIG.12A and FIG.12B). Without wishing to be bound by theory, this data helps to inform SAR of Nox4 inhibitors and understanding the optimal locations to attach the macrolide-based lung linker to Nox4 inhibitors without altering potency. Additionally, preliminary data (see above) suggests that attachment of the macrolide-lung linker may also alter predicted binding to Nox4, some indicating enhanced binding as compared to parent alone. i. DESIGN OF NOVEL LT-NOX4I SERIES [00464] LT-Nox4i candidates will be designed by integrating novel macrocycle lung- targeted linkers into the molecular architecture of previously identified top Nox4 inhibitor candidates. Candidates will be evaluated via in silico docking/binding simulations. ii. DEVELOP A LUNG-TARGETING NOX4 INHIBITOR SERIES AIMED TO ENHANCE DISTRIBUTION AND CONCENTRATION IN THE LUNG. [00465] Preliminary data suggests that macrocycle-based Nox4 inhibitors could significantly improve binding to Nox4 and selective distribution to the lung. If successfully validated, this will significantly advance the goal of improved Nox4 inhibitor distribution and bioavailability within the lung, which could potentially reduce toxicity risk. The ultimate goal of this study is to develop candidates that would increase drug efficacy in the lung, and mitigate potential systemic toxic effects. [00466] In order to validate a lung-targeting Nox4 inhibitor approach, macrolide-based Nox4 inhibitors will be designed and synthesized, integrating novel “lung-targeted linker” into the molecular architecture of top IV candidates. Previously identified top candidates (FIG.10) and/or top candidates developed as detailed above will be used as the starting point for these medicinal chemistry efforts. To date, a series of >50 lung-targeting Nox4 inhibitors have been developed around the UANOX048 series (FIG.11A and FIG.11B; representative example is shown); similar approaches will be employed under this study focusing on top candidates identified for IV delivery. iii. SCREENING CASCADE [00467] Compounds will be assessed as described below. Controls for all studies: DPI (pan-Nox inhibitor) will be used as a positive control for Nox inhibition; GKT136901 will be used as a positive control for scavenger activity; APX-115 (a putative competitor Nox inhibitor) will also be evaluated in parallel to compare performance. iv. POTENCY FOR NOX4 AND FALSE-POSITIVE SCREENING: [00468] Potency for Nox4. Synthesized analogs will be subjected to IC50 evaluation in a 96-well format with HEK/Nox4 cells, which generate high levels of H2O2. Efficacy for inhibition of H2O2 will be measured by Amplex red fluorescence assay. [00469] Cytotoxicity Assay. Ensuring that Nox4 inhibitors are not cytotoxic is a key parameter that requires assessment. Cell Titer Glo assay is an industry-standard that measures cellular ATP levels. Analogs will be evaluated in this assay relative to vehicle control. Digitonin (200 µg/ml) will be used as a positive control for cell death. [00470] Antioxidant Activity. Analogs will be incubated in 96-well-plates containing exogenous H2O2 (5 µM) and Amplex Red (a HRP-dependent assay mechanism to detect H2O2). Compounds that inhibit H2O2 in the absence of cells will be considered scavengers and will be eliminated. Catalase (750 U/ml) will also be used as a positive control for scavenger activity. [00471] Assay Interference. Analogs will be incubated in 96-well-plates containing exogenous H2O2 (5 µM) and ROS-GLO (an HRP-independent H2O2 detection system) to rule out false positives from potential compound interference with HRP. Catalase (750 U/ml) will be used as a positive control for scavenger activity. [00472] Xanthine Oxidase (XO) Assay. XO generates superoxide and H2O2 independent of Nox activity. This assay will be used to eliminate non-specific ROS scavengers. [00473] Potency for Nox2. A screening assay using RAW264.7 cells was utilized, which exhibit high Nox2-dependent H2O2 production upon stimulation with PMA (1 μM); H2O2 production will be measured by Amplex red assay. v. FUNCTIONAL SCREENING FOR IN VITRO EFFICACY [00474] Proliferation. ECs will be evaluated for BrdU incorporation (by ELISA). [00475] Inflammatory Responses. Senescent EC supernatant will be evaluated to assess changes in inflammatory cytokines using a Multiplex kit (Human Magnetic 65-Plex, ThermoFisher). [00476] Permeability. Senescent ECs will be plated in a confluent monolayer in electric cell-substrate impedance sensing (ECIS) array plates coated with 0.1% gelatin. Cells will be treated with Nox4 inhibitor and stimulated with LPS. Trans-endothelial electrical resistance (TEER) will be evaluated using an electrical cell substrate impedance sensing system (Applied Biophysics): b. EVALUATE IN VITRO ADME AND IN VIVO PK/PD OF LUNG-TARGETING NOX4 INHIBITORS [00477] Functional screening will be performed to confirm that placement/attachment of the linker to Nox4 inhibitors does not detrimentally impact in vitro efficacy. i. IN VITRO ADME (ABSORBTION, DISTRIBUTION, METABOLISM, EXCRETION) [00478] Determination of aqueous stability. As an IV route of administration for acute conditions is being targeted, assessment of compounds in aqueous media is an important factor to consider in identifying a lead. [00479] Kinetic and thermodynamic solubility. Adequate aqueous solubility is a pre- requisite for a drug designed for IV route of administration, to this end, it is important to track and optimize solubility, in order to develop a successful candidate. Goals will be to achieve thermodynamic solubility >200 µM at physiological pH in 0.5% aqueous DMSO, and aqueous solubility >10 µM at physiological pH. [00480] LogD. LogD is a measure of compound lipophilicity. The distribution coefficient is determined between octanol and an aqueous phase buffered to physiological pH. The value is an important metric and most typically marketed small molecule drug molecules have a LogD between 1-3. [00481] PPB (Plasma Protein Binding). Binding of compounds to human serum albumin will be measured. This assay will provide the information required to determine that bioavailability of free compound for interaction with Nox4 to elicit inhibitory effect. Compounds that are highly protein bound, have little or no free fraction to elicit a response and this often requires optimization. [00482] Polar Surface Area. Polar surface area will be calculated. [00483] Cytochrome P450 (CYP) Inhibition. The potential for a compound to inhibit CYP oxidative enzymes is indicative of the potential for undesirable drug-drug interactions. Compounds will be tested against selected CYP isoforms. These studies will also identify metabolism products, including reactive metabolites. ii. IN VIVO PK AND TISSUE DISTRIBUTION [00484] Scale-up: Scale-up of selected lead analogs to gram quantities will be required for in vivo studies. Successful and reproducible scale-up of analogs from 200 mg to 8 g quantities has been previously demonstrated. Analogs will be tailored to 3-4 step synthesis protocols using commercially available materials. This approach will allow synthesis of molecules at grams quantities with minimal or no batch-to-batch variations. [00485] C57BL/6 male mice will be administered candidates in a single dose (1 mg/kg) via IV administration. Mice will be sacrificed by CO2 inhalation at various time points (0, 30m, 1, 2, 4, 6, 8, 24h) following drug administration. Blood plasma will be isolated, and tissues (lung, heart, liver, kidney, and spleen) will be harvested and snap frozen in liquid nitrogen. Tissues will be then homogenized in 300 ul of acetonitrile with a mechanical homogenizer, centrifuged, and supernatant will be used for analyses. Plasma and tissue concentration over time will be determined by liquid chromatography/mass spectroscopy (LC/MS). [00486] It is recognized that gender-dependent differences in metabolism are known to exist, which may lead to PK profiles that are different between males and females. However, industry standard at this stage of pre-clinical development is to perform PK profiling in one gender; at this stage of development the priority is to evaluate the greatest number of analogs. ARDS is more prevalent in males (>60% of ARDS patients are male), and COVID-19-ARDS mortality is 2.4 times greater in males compared to females. Thus, initial efforts will utilize male mice only. However, the top 2 candidates will also be evaluated for their PK profile in female mice. [00487] Specific Measured Endpoints. Standard PK parameters of clearance, drug half- life (T1/2), Tmax, Cmax, Cmin, drug elimination constant (ke), drug absorption constant (ka), and area under the curve (AUC), bioavailability, and lung/plasma ratio will be calculated. c. DETERMINATION OF THE THERAPEUTIC INDEX OF TOP CANDIDATE AS A NOVEL TREATMENT FOR AGE-ASSOCIATED ARDS [00488] The top candidates (as determined above) will be advanced to determine the Therapeutic Index (TI), the window of safe and effective dosing, which must be established for IND-enabling studies will be established for the compounds. TI is calculated as TD50/ED50 (TD = toxic dose; ED = effective dose) within the same species. TD and ED will be evaluated. i. EVALUATE EFFICACY OF OPTIMIZED LEAD CANDIDATE FORMULATIONS VIA IV DELIVERY IN 2 MURINE MODELS OF PRE- CLINICAL ARDS [00489] Important target identification and validation data implicating Nox4 as a viable target for age-associated severe ARDS has been shown in various studies.2 murine models that have previously validated Nox4 upregulation following injury will be utilized. Genetic targeting of Nox4 in a CLP model led to reduced lung ROS levels and improved survival, whereas knockdown of Nox1, Nox2 or p47phox had no effects. Preliminary studies with a novel eNox4 KO mouse model demonstrate that selective genetic ablation of endothelial Nox4 leads to striking protection in aged mice (when Nox4 is persistently expressed), as compared to modest protection in young cohorts (FIG.6). The significantly elevated Nox4/ROS in this aging model offers a larger therapeutic window to evaluate the extent of Nox4 inhibitor efficacy and to identify the most promising candidates that can reduce Nox4-dependent pathological effects to the greatest extent. Evaluation of the efficacy of the top 2 most promising candidates using 2 murine model of pre-clinical ARDS will be performed; the ED50 of the top two candidates will be determined in each model. [00490] Candidates will be assessed using the murine models described below. For all studies, candidates will be administered via IV delivery through tail vein injection at 4h post- initial injury (for both models), 5 different dose concentrations will be used for each candidate to determine ED curves, and mice will be sacrificed at 24h after initial injury by exsanguination and bilateral thoracotomy for endpoint analyses. [00491] Cecal Ligation Puncture (CLP) model: C57BL/6 mice (2m) will be anesthetized with isoflurane. Skin will be disinfected and a 1 cm incision will be made in the middle of the abdomen, allowing the cecum to be exposed. A braided silk suture will be passed through the midpoint between the colon root and cecum terminal to ligate the cecum. A 21-gauge needle will be inserted into the ligated cecum and a small drop of the intestinal content will be squeezed out to induce infection. The cecum will then be repositioned, and the incision closed. [00492] 2-hit aging model of severe ARDS: Aged (20m) C57BL/6 mice will be anesthetized by intraperitoneal (IP) injection of ketamine (80 mg/kg; anesthetic) and xylazine (5 mg/kg; analgesic) and subjected to LPS (0.2mg/kg in PBS in 50μl) via IT administration. At 20h post-LPS, anesthetized mice will be subjected to VILI by high tidal volume ventilation for 4h (room air, 20 ml/kg tidal volume, 85 breaths/min; Inspira rodent ventilator, Harvard Apparatus). [00493] Specific Measured Endpoints: [00494] Lung injury (barrier dysfunction and inflammatory responses): i) Total BAL cells: evaluated by Coulter counter, ii) Total BAL protein: evaluated by BCA assay. iii) Neutrophil influx: cytospin preparations of cellular BAL fraction will be stained with Hema 3 solution, and % neutrophils will be quantified. iv) Albumin influx: non-cellular BAL fraction will be evaluated by albumin assay kit, v) Lung permeability: Mice will be given Evans Blue dye via tail vein injection and lung tissue evaluated by extravasation assay. vi) Pro-inflammatory mediators: assessed by Multiplex kit (Mouse Magnetic 65-Plex, ThermoFisher). vii) Lung injury score: H&E lung sections will be blindly evaluated and scored (HistoWiz) using a previously defined scoring system. [00495] Oxidative stress: Lung BAL will be evaluated for ROS (Amplex Red assay). [00496] Physiological assessments: i) lung compliance will be evaluated by FlexiVent. ii) Lung weight, iii) body weight, and iv) survival will be monitored/recorded. ii. EVALUATE DOSE TOLERABILITY AND SAFETY IN A RODENT MODEL [00497] The information obtained will establish the safety/tolerance of the top two candidates in healthy mice, as a precursor to IND-enabling studies. Without wishing to be bound by theory, one objective is to identify the Maximum Tolerated Dose (MTD) and the no- observed-adverse-effect level (NOAEL), the highest dose with no detected effects. [00498] Assess the acute repeated-dose tolerance in healthy mice: Candidates will be evaluated in rising dose tolerance studies conducted in healthy aged (24m) mice. Preliminary data with the parent compound from various studies (at 50mg/kg) will be used as the starting point, the “safety margin” above that dose will be further interrogated in an increasing repeat dose study (dose will increase each day until side-effects are observed). The safety margin is the difference between the NOAEL dose in non-clinical species and the starting clinical dose, aiming at approximately 3-10-fold above the proposed clinical dose. Mice will be dosed daily via IV delivery with increasing concentrations of candidates until evidence of toxicity; vehicle will be administered as a control group. The resulting toxicity dose-response curves will be used to calculate TD50, which will be used (along with ED50) for deriving the TI. [00499] Specific Measured Endpoints: Animals will be assessed for clinical signs of tolerance, body weight, gross pathology, hematology, clinical chemistry and by histopathology to assign the NOAEL for both acute and repeated dosing. Body weight will be measured prior to test article dosing, at necropsy and at any interval where clinical signs of toxicity are observed. Food consumption will be monitored. Detailed clinical observations will be conducted according to standard operating procedure (SOP) with special attention paid to signs associated with the respiratory tract. These include but are not limited to apnea, labored breathing, malaise, marked nasal discharge, etc. Gross pathology will consist of a complete external and internal examination including body orifices (ears, nostrils, mouth, anus, etc.) and cranial, thoracic, and abdominal organs and tissues. All gross findings will be recorded, including size, shape, color, and consistency. Organs with lesions will be fixed for histopathologic evaluation. Blood will be collected at regular intervals during treatment to correlate drug levels with toxicity results. Hematology will be conducted by an Advia 120 Series Hematology System. Clinical chemistry will be performed to quantify endpoints (e.g. albumin, calcium, chloride, creatinine, glucose, potassium, protein, triglycerides). Blood and lung tissue will be collected at terminal necropsy for quantification of drug and correlation to biological finding of tolerance. TD will be determined by clinical observations, chiefly the side effects can range from mild effects such as reduced weight gain, moderate effects such as weight loss up to 20% or substantial effects such as unresponsiveness. d. SCIENTIFIC RIGOR AND STATISTICAL ANALYSES [00500] Statistical significance will be analyzed using Prism 7 (GraphPad Software) and p < 0.05 will be considered significant. Student’s t-tests will be used when comparing two groups. When comparing 3 or more groups, 2-way analysis of variance (ANOVA) with Bonferroni post- test will be performed. p<0.05 will be considered significant. A power analysis was performed to calculate the number of mice needed per experimental arm. The minimal number of rodents to obtain reliable scientific results will be used; the numbers in each group were estimated based on a power analysis using α=0.05. To control potential bias, all murine studies proposed will be randomized into the groups and assessors will be blinded to treatment groups. 7. EVALUATION OF NOX4 INHIBITORS HAVING A LUNG-TARGETED LINKER a. BIOLOGICAL ASSAYS [00501] Potency for Nox4. Analogs were subjected to IC50 evaluation in a 96-well format with HEK/Nox4 cells, which generate high levels of H2O2. Efficacy for inhibition of H2O2 will be measured by Amplex red fluorescence assay. [00502] Cytotoxic Assay. Ensuring that Nox4 inhibitors are not cytotoxic is a key parameter that requires assessment. Cell Titer Glo assay is an industry-standard that measures cellular ATP levels. Analogs were evaluated in this assay relative to vehicle control. Digitonin (200 µg/ml) was used as a positive control for cell death. [00503] Antioxidant Activity. Analogs were incubated in 96-well-plates containing exogenous H2O2 (5 µM) and Amplex Red (a HRP-dependent assay mechanism to detect H2O2). Compounds that inhibit H2O2 in the absence of cells were considered scavengers and eliminated. Catalase (750 U/ml) was also be used as a positive control for scavenger activity. [00504] Assay Interference. Analogs were incubated in 96-well-plates containing exogenous H2O2 (5 µM) and ROS-GLO (an HRP-independent H2O2 detection system) to rule out false positives from potential compound interference with HRP. Catalase (750 U/ml) were used as a positive control for scavenger activity. [00505] Xanthine Oxidase (XO) Assay. XO generates superoxide and H2O2 independent of Nox activity. This assay will be used to eliminate non-specific ROS scavengers. [00506] Potency for Nox2. A screening assay using RAW264.7 cells, which exhibit high Nox2-dependent H2O2 production upon stimulation with PMA (1 μM), was employed. H2O2 production was measured by Amplex red assay. b. EVALUATION OF MACROLIDE-NOX4 CONJUGATES [00507] Exemplary macrolide-Nox4 conjugates as shown in Table 1 were evaluated using the assays detailed above, and the results are shown in Table 7 below.
