Description Respiratory viral infections, including upper and lower respiratory tract viral infections, are a leading cause of death of millions of people each year. Upper respiratory tract viral infections involve the nose, sinuses, pharynx and/or larynx. Lower respiratory tract viral infections involve the respiratory system below the vocal cords, including the trachea, primary bronchi and lungs. Human respiratory syncytial virus (RSV) is a common cause of respiratory tract infections. Up to 60% of human infants are infected with RSV within their first year of life. Children and adults are also infected with RSV, where it is often manifesting as a lower respiratory tract infection with possible complications of bronchiolitis. RSV infections can be particularly severe in infants and elderly patients. RSV is a negative-sense, single-stranded RNA virus classified within the Paramyxoviridae family, which also includes viruses that cause Newcastle disease, parainfluenza, mumps, measles, and canine distemper.

BRIEF DESCRIPTION OF THE DRAWINGS Figure 1 illustrates examples of additional agents.
DETAILED DESCRIPTION Paramyxoviridae family is a family of single stranded RNA viruses.
Several genera of the paramyxoviridae family include henipavirus, morbillivirus, respirovirus, rubulavirus, pneumovirus and metapneumovirus. These viruses can be transmitted person to person via direct or close contact with contaminated respiratory droplets or fomites. Species of henipavirus include hendravirus and nipahvirus. A species of morbillivirus is measles. Species of respirovirus include sendai virus and human parainfluenza viruses 1 and 3; and species of rubulavirus include mumps virus and human parainfluenza viruses 2 and 4. A species of metapneumovirus is human metapneumovirus.
Human Respiratory Syncytial Virus (RSV), a species of pneumovirus, can cause respiratory infections, and can be associated with bronchiolitis and pneumonia.
Symptoms of an RSV infection include coughing, sneezing, runny nose, fever, decrease in appetite, and wheezing. RSV is the most common cause of bronchiolitis and pneumonia in children under one year of age in the world, and can be the cause of tracheobronchitis in older children and adults. In the United States, between 75,000 and 125,000 infants are hospitalized each year with RSV. Among adults older than 65 years of age, an estimated 14,000 deaths and 177,000 hospitalizations have been attributed to RSV.
Treatment options for people infected with RSV are currently limited.
Antibiotics, usually prescribed to treat bacterial infections, and over-the-counter medication are not effective in treating RSV. In severe cases, a nebulized bronchodilator, such as albuterol, may be prescribed to relieve some of the symptoms, such as wheezing.
RespiGram® (RSV-IGIV, MedImmune, approved for high risk children younger than 24 months of age), Synagis® (palivizumab, MedImmune, approved for high risk children younger than 24 months of age), and Virzole® (ribavirin by aerosol, ICN pharmaceuticals) have been approved for treatment of RSV.
Symptoms of the measles include fever, cough, runny nose, red eyes and a generalized rash. Some individuals with measles can develop pneumonia, ear infections and bronchitis. Mumps leads to swelling of the salivary glands. Symptoms of mumps include fever, loss of appetite and fatigue. Individuals are often immunized against measles and mumps via a three-part MMR vaccine (measles, mumps, and rubella). Human parainfluenza virus includes four serotypes types, and can cause upper and lower respiratory tract infections. Human parainfluenza virus 1 (HPIV-1) can be associated with croup; human parainfluenza virus 3 (HPIV-3) can be associated with bronchiolitis and pneumonia.
According to the Centers of Disease Control and Prevention (CDC), there are no vaccines against human parainfluenza virus.
Definitions Unless defined otherwise, all technical and scientific terms used herein have the same meaning as is commonly understood by one of ordinary skill in the art. All patents, applications, published applications and other publications referenced herein are incorporated by reference in their entirety unless stated otherwise.

That is, the alkyl, alkenyl, alkynyl, ring(s) of the cycloalkyl, ring(s) of the cycloalkenyl, ring(s) of the aryl, ring(s) of the heteroaryl or ring(s) of the heteroalicyclyl can contain from "a" to "b", inclusive, carbon atoms. Thus, for example, a "C to C alkyl" group refers to all alkyl groups having from 1 to 4 carbons, that is, CH -, CH CH -, CH CH CH -, (CH ) CH-, 3 3 2 3 2 2 3 2 CH CH CH CH -, CH CH CH(CH )- and (CH ) C-. If no "a" and "b" are designated with 3 2 2 2 3 2 3 3 3 regard to an alkyl, alkenyl, alkynyl, cycloalkyl cycloalkenyl, aryl, heteroaryl or heteroalicyclyl group, the broadest range described in these definitions is to be assumed.
As used herein, "alkyl" refers to a straight or branched hydrocarbon chain that comprises a fully saturated (no double or triple bonds) hydrocarbon group. The alkyl group may have 1 to 20 carbon atoms (whenever it appears herein, a numerical range such as "1 to 20" refers to each integer in the given range; e.g., "1 to 20 carbon atoms" means that the alkyl group may consist of 1 carbon atom, 2 carbon atoms, 3 carbon atoms, etc., up to and including 20 carbon atoms, although the present definition also covers the occurrence of the term "alkyl" where no numerical range is designated). The alkyl group may also be a medium size alkyl having 1 to 10 carbon atoms. The alkyl group could also be a lower alkyl having 1 to 6 carbon atoms. The alkyl group of the compounds may be designated as "C -C alkyl" or similar designations. By way of example only, "C -C alkyl" indicates that there are one to four carbon atoms in the alkyl chain, i.e., the alkyl chain is selected from methyl, ethyl, propyl, iso-propyl, n-butyl, iso-butyl, sec-butyl, and t-butyl.

A cycloalkyl group may be unsubstituted or substituted. Typical cycloalkyl groups include, but are in no way limited to, cyclopropyl, cyclobutyl, cyclopentyl, cyclohexyl, cycloheptyl and cyclooctyl.
As used herein, "cycloalkenyl" refers to a mono- or multi- cyclic hydrocarbon ring system that contains one or more double bonds in at least one ring; although, if there is more than one, the double bonds cannot form a fully delocalized pi- electron system throughout all the rings (otherwise the group would be "aryl," as defined herein). Cycloalkenyl groups can contain 3 to 10 atoms in the ring(s) or 3 to 8 atoms in the ring(s). When composed of two or more rings, the rings may be connected together in a fused fashion. A cycloalkenyl group may be unsubstituted or substituted.
As used herein, "aryl" refers to a carbocyclic (all carbon) monocyclic or multicyclic aromatic ring system (including fused ring systems where two carbocyclic rings share a chemical bond) that has a fully delocalized pi-electron system throughout all the rings. The number of carbon atoms in an aryl group can vary. For example, the aryl group can be a C -C aryl group, a C -C aryl group, or a C aryl group. Examples of aryl groups 6 14 6 10 6 include, but are not limited to, benzene, naphthalene and azulene. An aryl group may be substituted or unsubstituted.

The number of atoms in the ring(s) of a heteroaryl group can vary. For example, the heteroaryl group can contain 4 to 14 atoms in the ring(s), 5 to 10 atoms in the ring(s) or 5 to 6 atoms in the ring(s). Furthermore, the term "heteroaryl" includes fused ring systems where two rings, such as at least one aryl ring and at least one heteroaryl ring, or at least two heteroaryl rings, share at least one chemical bond. Examples of heteroaryl rings include, but are not limited to, those described herein and the following: furan, furazan, thiophene, benzothiophene, phthalazine, pyrrole, oxazole, benzoxazole, 1,2,3- oxadiazole, 1,2,4-oxadiazole, thiazole, 1,2,3-thiadiazole, 1,2,4-thiadiazole, benzothiazole, imidazole, benzimidazole, indole, indazole, pyrazole, benzopyrazole, isoxazole, benzoisoxazole, isothiazole, triazole, benzotriazole, thiadiazole, tetrazole, pyridine, pyridazine, pyrimidine, pyrazine, purine, pteridine, quinoline, isoquinoline, quinazoline, quinoxaline, cinnoline and triazine.

A heterocycle may optionally contain one or more unsaturated bonds situated in such a way, however, that a fully delocalized pi-electron system does not occur throughout all the rings. The heteroatom(s) is an element other than carbon including, but not limited to, oxygen, sulfur, and nitrogen. A heterocycle may further contain one or more carbonyl or thiocarbonyl functionalities, so as to make the definition include oxo-systems and thio- systems such as lactams, lactones, cyclic imides, cyclic thioimides and cyclic carbamates.
When composed of two or more rings, the rings may be joined together in a fused fashion.
Additionally, any nitrogens in a heterocyclyl may be quaternized. Heterocyclyl or heteroalicyclic groups may be unsubstituted or substituted.

Pharmaceutical Compositions Some embodiments described herein relate to a pharmaceutical composition, that can include an effective amount of one or more compounds described herein (e.g., a compound of Formula (I), or a pharmaceutically acceptable salt thereof) and a pharmaceutically acceptable carrier, diluent, excipient or combination thereof.
The term "pharmaceutical composition" refers to a mixture of one or more compounds disclosed herein with other chemical components, such as diluents or carriers.
The pharmaceutical composition facilitates administration of the compound to an organism.
Pharmaceutical compositions can also be obtained by reacting compounds with inorganic or organic acids such as hydrochloric acid, hydrobromic acid, sulfuric acid, nitric acid, phosphoric acid, methanesulfonic acid, ethanesulfonic acid, p-toluenesulfonic acid, and salicylic acid. Pharmaceutical compositions will generally be tailored to the specific intended route of administration.
The term "physiologically acceptable" defines a carrier, diluent or excipient that does not abrogate the biological activity and properties of the compound nor cause appreciable damage or injury to an animal to which delivery of the composition is intended.
As used herein, a "carrier" refers to a compound that facilitates the incorporation of a compound into cells or tissues. For example, without limitation, dimethyl sulfoxide (DMSO) is a commonly utilized carrier that facilitates the uptake of many organic compounds into cells or tissues of a subject.
As used herein, a "diluent" refers to an ingredient in a pharmaceutical composition that lacks appreciable pharmacological activity but may be pharmaceutically necessary or desirable. For example, a diluent may be used to increase the bulk of a potent drug whose mass is too small for manufacture and/or administration. It may also be a liquid for the dissolution of a drug to be administered by injection, ingestion or inhalation. A common form of diluent in the art is a buffered aqueous solution such as, without limitation, phosphate buffered saline that mimics the pH and isotonicity of human blood.
As used herein, an "excipient" refers to an essentially inert substance that is added to a pharmaceutical composition to provide, without limitation, bulk, consistency, stability, binding ability, lubrication, disintegrating ability etc., to the composition. A "diluent" is a type of excipient.
The pharmaceutical compositions described herein can be administered to a human patient per se, or in pharmaceutical compositions where they are mixed with other active ingredients, as in combination therapy, or carriers, diluents, excipients or combinations thereof. Proper formulation is dependent upon the route of administration chosen.
Techniques for formulation and administration of the compounds described herein are known to those skilled in the art.
The pharmaceutical compositions disclosed herein may be manufactured in a manner that is itself known, e.g., by means of conventional mixing, dissolving, granulating, dragee-making, levigating, emulsifying, encapsulating, entrapping or tableting processes. Additionally, the active ingredients are contained in an amount effective to achieve its intended purpose. Many of the compounds used in the pharmaceutical combinations disclosed herein may be provided as salts with pharmaceutically compatible counterions.
Multiple techniques of administering a compound exist in the art including, but not limited to, oral, rectal, pulmonary, topical, aerosol, injection and parenteral delivery, including intramuscular, subcutaneous, intravenous, intramedullary injections, intrathecal, direct intraventricular, intraperitoneal, intranasal and intraocular injections.
One may also administer the compound in a local rather than systemic manner, for example, via injection or implantation of the compound directly into the affected area, often in a depot or sustained release formulation. Furthermore, one may administer the compound in a targeted drug delivery system, for example, in a liposome coated with a tissue-specific antibody. The liposomes will be targeted to and taken up selectively by the organ. For example, intranasal or pulmonary delivery to target a respiratory infection may be desirable.
The compositions may, if desired, be presented in a pack or dispenser device which may contain one or more unit dosage forms containing the active ingredient.
The pack may for example comprise metal or plastic foil, such as a blister pack. The pack or dispenser device may be accompanied by instructions for administration. The pack or dispenser may also be accompanied with a notice associated with the container in form prescribed by a governmental agency regulating the manufacture, use, or sale of pharmaceuticals, which notice is reflective of approval by the agency of the form of the drug for human or veterinary administration. Such notice, for example, may be the labeling approved by the U.S. Food and Drug Administration for prescription drugs, or the approved product insert. Compositions that can include a compound described herein formulated in a compatible pharmaceutical carrier may also be prepared, placed in an appropriate container, and labeled for treatment of an indicated condition.

As used herein, a "subject" refers to an animal that is the object of treatment, observation or experiment. "Animal" includes cold- and warm-blooded vertebrates and invertebrates such as fish, shellfish, reptiles and, in particular, mammals.
"Mammal" includes, without limitation, mice, rats, rabbits, guinea pigs, dogs, cats, sheep, goats, cows, horses, primates, such as monkeys, chimpanzees, and apes, and, in particular, humans. In some embodiments, the subject is human.
As used herein, the terms "prevent" and "preventing," mean lowering the efficiency of viral replication and/or inhibiting viral replication to a greater degree in a subject who receives the compound compared to a subject who does not receive the compound. Examples of forms of prevention include prophylactic administration to a subject who has been or may be exposed to an infectious agent, such as a paramyxovirus (e.g., RSV).
As used herein, the terms "treat," "treating," "treatment," "therapeutic," and "therapy" do not necessarily mean total cure or abolition of the disease or condition. Any alleviation of any undesired signs or symptoms of a disease or condition, to any extent can be considered treatment and/or therapy. Furthermore, treatment may include acts that may worsen the subject’s overall feeling of well-being or appearance, and may positively affect one or more symptoms or aspects of the disease while having effects on other aspects of the disease or on unrelated systems that may be considered undesireable.
The terms "therapeutically effective amount" and "effective amount" are used to indicate an amount of an active compound, or pharmaceutical agent, that elicits the biological or medicinal response indicated. For example, a therapeutically effective amount of compound can be the amount needed to prevent, treat, alleviate or ameliorate one or more symptoms or conditions of disease or prolong the survival of the subject being treated This response may occur in a tissue, system, animal or human and includes alleviation of the signs or symptoms of the disease being treated. Determination of an effective amount is well within the capability of those skilled in the art, in view of the disclosure provided herein. The therapeutically effective amount of the compounds disclosed herein required as a dose will depend on the route of administration, the type of animal, including human, being treated, and the physical characteristics of the specific animal under consideration. The dose can be tailored to achieve a desired effect, but will depend on such factors as weight, diet, concurrent medication and other factors which those skilled in the medical arts will recognize.
Various indicators for determining the effectiveness of a method for treating a viral infection, such as a paramyxovirus, are known to those skilled in the art.
Example of suitable indicators include, but are not limited to, a reduction in viral load, a reduction in viral replication, a reduction in viral RNA, a reduction in time to seroconversion (virus undetectable in patient serum), a reduction of morbidity or mortality in clinical outcomes, and/or other indicator of disease response.
In some embodiments, an effective amount of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, is an amount that is effective to reduce viral titers to essentially undetectable or very low levels, for example, to less than 1.7 log plaque forming units equivalents (PFUe)/mL, or less than 0.3 log plaque forming units equivalents (PFUe)/mL. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can reduce the viral load compared to the viral load before administration of the combination (for example, 60 hours after receiving the initial dosage of the combination). In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, described herein can reduce the viral load to lower than 1.7 log (PFUe)/mL, or lower than 0.3 log (PFUe)/mL. In some embodiments, a combination of compounds described herein can achieve a reduction in viral titer in the serum of the subject in the range of about 1.5-log to about a 2.5-log reduction, about a 3-log to about a 4-log reduction, or a greater than about 5-log reduction compared to the viral load before administration of the combination. For example, the viral load is measure before administration of the combination, and several hours after receiving the initial dosage of the combination (for example, 60 hours after receiving the initial dosage of the combination).
In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in at least a 1, 2, 3, 4, 5, 10, 15, 20, 25, 50, 75, 100-fold or more reduction in the replication of a paramyxovirus relative to pre-treatment levels in a subject, as determined several hours after receiving the initial dosage of the combination (for example, 60 hours after receiving the initial dosage of the combination). In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, described herein can result in a reduction of the replication of a paramyxovirus relative to pre-treatment levels in the range of about 2 to about 5 fold, about 10 to about 20 fold, about to about 40 fold, or about 50 to about 100 fold. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can result in a reduction of a paramyxovirus replication in the range of 1 to 1.5 log, 1.5 log to 2 log, 2 log to 2.5 log, 2.5 to 3 log, 3 log to 3.5 log or 3.5 to 4 log more reduction of a paramyxovirus replication compared to the reduction of a paramyxovirus reduction achieved by ribavirin (Virazole®), or may achieve the same reduction as that of ribavirin (Virazole®) therapy in a shorter period of time, for example, in one day, two days, three days, four days, or five days, as compared to the reduction achieved after 5 days of ribavirin (Virazole®) therapy.
After a period of time, infectious agents can develop resistance to one or more therapeutic agents. The term "resistance" as used herein refers to a viral strain displaying a delayed, lessened and/or null response to a therapeutic agent(s). For example, after treatment with an antiviral agent, the viral load of a subject infected with a resistant virus may be reduced to a lesser degree compared to the amount in viral load reduction exhibited by a subject infected with a non-resistant strain. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered to a subject infected with RSV that is resistant to one or more different anti-RSV agents (for example, ribavirin). In some embodiments, development of resistant RSV strains is delayed when subjects are treated with a compound of Formula (I), or a pharmaceutically acceptable salt thereof, compared to the development of RSV strains resistant to other RSV drugs.
In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can decrease the percentage of subjects that experience complications from a RSV viral infection compared to the percentage of subjects that experience complication being treated with ribavirin. For example, the percentage of subjects being treated with a compound of Formula (I), or a pharmaceutically acceptable salt thereof, that experience complications can be 10% , 25%, 40%, 50%, 60%, 70%, 80% and 90% less compared to subjects being treated with ribavirin.
In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, or a pharmaceutical composition that includes a compound described herein, can be used in combination with one or more additional agent(s). In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be used in combination with one or more agents currently used in a conventional standard of care for treating RSV. For example, the additional agent can be ribavirin, palivizumab, and RSV-IGIV. For the treatment of RSV, additional anti-RSV agents include but are not limited to an anti-RSV antibody, a fusion protein inhibitor, an N-protein inhibitor, a RSV polymerase inhibitor, an IMPDH inhibitor, an interferon and an other compound that inhibits the RSV virus, or a pharmaceutically acceptable salt of any of the foregoing. A non-limiting list of examples of additional agents is provided herein.

The order of administration of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, with one or more additional agent(s) can vary. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered prior to all additional agents. In other embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered prior to at least one additional agent. In still other embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered concomitantly with one or more additional agent(s). In yet still other embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered subsequent to the administration of at least one additional agent. In some embodiments, a compound of Formula (I), or a pharmaceutically acceptable salt thereof, can be administered subsequent to the administration of all additional agents.
A potential advantage of utilizing a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table), including pharmaceutically acceptable salts and prodrugs thereof, may be a reduction in the required amount(s) of one or more compounds of paragraphs [0198]-[0199] (including the table) (including pharmaceutically acceptable salts and prodrugs thereof) that is effective in treating a disease condition disclosed herein (for example, RSV), as compared to the amount required to achieve same therapeutic result when one or more compounds described in paragraphs -[0199] (including the table), including pharmaceutically acceptable salts thereof, are administered without a compound of Formula (I), or a pharmaceutically acceptable salt thereof. For example, the amount of a compound described in paragraphs [0198]-[0199] (including the table), including a pharmaceutically acceptable salt and prodrug thereof, can be less compared to the amount of the compound described in paragraphs [0198]-[0199] (including the table), including a pharmaceutically acceptable salt and prodrug thereof, needed to achieve the same viral load reduction when administered as a monotherapy.
Another potential advantage of utilizing a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table), including pharmaceutically acceptable salts and prodrugs thereof, is that the use of two or more compounds having different mechanism of actions can create a higher barrier to the development of resistant viral strains compared to the barrier when a compound is administered as monotherapy.
Additional advantages of utilizing a compound of Formula (I), or a pharmaceutically acceptable salt thereof, in combination with one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table), including pharmaceutically acceptable salts and prodrugs thereof, may include little to no cross resistance between a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table) (including pharmaceutically acceptable salts and prodrugs thereof); different routes for elimination of a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table) (including pharmaceutically acceptable salts and prodrugs thereof); little to no overlapping toxicities between a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table) (including pharmaceutically acceptable salts and prodrugs thereof); little to no significant effects on cytochrome P450; and/or little to no pharmacokinetic interactions between a compound of Formula (I), or a pharmaceutically acceptable salt thereof, and one or more additional agent(s) described in paragraphs [0198]-[0199] (including the table), including pharmaceutically acceptable salts and prodrugs thereof).
As will be readily apparent to one skilled in the art, the useful in vivo dosage to be administered and the particular mode of administration will vary depending upon the age, weight, the severity of the affliction, and mammalian species treated, the particular compounds employed, and the specific use for which these compounds are employed. The determination of effective dosage levels, that is the dosage levels necessary to achieve the desired result, can be accomplished by one skilled in the art using routine methods, for example, human clinical trials and in vitro studies.
The dosage may range broadly, depending upon the desired effects and the therapeutic indication. Alternatively dosages may be based and calculated upon the surface area of the patient, as understood by those of skill in the art. Although the exact dosage will be determined on a drug-by-drug basis, in most cases, some generalizations regarding the dosage can be made. The daily dosage regimen for an adult human patient may be, for example, an oral dose of between 0.01 mg and 3000 mg of each active ingredient, preferably between 1 mg and 700 mg, e.g. 5 to 200 mg. The dosage may be a single one or a series of two or more given in the course of one or more days, as is needed by the subject. In some embodiments, the compounds will be administered for a period of continuous therapy, for example for a week or more, or for months or years.
In instances where human dosages for compounds have been established for at least some condition, those same dosages may be used, or dosages that are between about 0.1% and 500%, more preferably between about 25% and 250% of the established human dosage. Where no human dosage is established, as will be the case for newly- discovered pharmaceutical compositions, a suitable human dosage can be inferred from ED or ID values, or other appropriate values derived from in vitro or in vivo studies, as qualified by toxicity studies and efficacy studies in animals.
In cases of administration of a pharmaceutically acceptable salt, dosages may be calculated as the free base. As will be understood by those of skill in the art, in certain situations it may be necessary to administer the compounds disclosed herein in amounts that exceed, or even far exceed, the above-stated, preferred dosage range in order to effectively and aggressively treat particularly aggressive diseases or infections.
Dosage amount and interval may be adjusted individually to provide plasma levels of the active moiety which are sufficient to maintain the modulating effects, or minimal effective concentration (MEC). The MEC will vary for each compound but can be estimated from in vitro data. Dosages necessary to achieve the MEC will depend on individual characteristics and route of administration. However, HPLC assays or bioassays can be used to determine plasma concentrations. Dosage intervals can also be determined using MEC value. Compositions should be administered using a regimen which maintains plasma levels above the MEC for 10-90% of the time, preferably between 30-90% and most preferably between 50-90%. In cases of local administration or selective uptake, the effective local concentration of the drug may not be related to plasma concentration.
It should be noted that the attending physician would know how to and when to terminate, interrupt, or adjust administration due to toxicity or organ dysfunctions.
Conversely, the attending physician would also know to adjust treatment to higher levels if the clinical response were not adequate (precluding toxicity). The magnitude of an administrated dose in the management of the disorder of interest will vary with the severity of the condition to be treated and to the route of administration. The severity of the condition may, for example, be evaluated, in part, by standard prognostic evaluation methods. Further, the dose and perhaps dose frequency, will also vary according to the age, body weight, and response of the individual patient. A program comparable to that discussed above may be used in veterinary medicine.
Compounds disclosed herein can be evaluated for efficacy and toxicity using known methods. For example, the toxicology of a particular compound, or of a subset of the compounds, sharing certain chemical moieties, may be established by determining in vitro toxicity towards a cell line, such as a mammalian, and preferably human, cell line. The results of such studies are often predictive of toxicity in animals, such as mammals, or more specifically, humans. Alternatively, the toxicity of particular compounds in an animal model, such as mice, rats, rabbits, or monkeys, may be determined using known methods. The efficacy of a particular compound may be established using several recognized methods, such as in vitro methods, animal models, or human clinical trials. When selecting a model to determine efficacy, the skilled artisan can be guided by the state of the art to choose an appropriate model, dose, route of administration and/or regime.
Synthesis Compounds of Formula (I), and those described herein may be prepared in various ways. Some compounds of Formula (I) can be obtained commercially and/or prepared utilizing known synthetic procedures. General synthetic routes to the compounds of Formula (I), and some examples of starting materials used to synthesize the compounds of Formula (I) are shown and described herein. The routes shown and described herein are illustrative only and are not intended, nor are they to be construed, to limit the scope of the claims in any manner whatsoever.

Microbiol. (1971) 22(5):797–801 with slight modifications. HEp-2 cells (ATCC#, CCL-23) are seeded at a density of 1,500 cells/30 µl/well into the 384-well cell plate(s) (Corning#3701) one day prior to the assay. Compounds are added into 384-well cell plates by Labcyte POD 810 Plate Assembler system. Each of the test compounds is provided to duplicate wells of a 384-well cell plate at final concentrations starting from 100 µM or 1 µM using 1/3 stepwise dilutions for 9 points. Quick-thaw Respiratory Syncytial Virus (RSV) long strain (ATCC#VR-26) stock in a 37C water bath. Place on ice until ready to use.
Viruses are diluted to the concentration of 100 TCID /30 µL with medium and 30 µl diluted RSV are added into related wells of 384-well cell plates. For each plate, sixteen wells are set aside as uninfected, untreated cell controls (CC), and nine wells per test plate receive virus only as a control for virus replication (VC). The final DMSO concentration of all wells is 1%. Place the plates at 37C, 5% CO for 5 days.
After 5 days incubation, observe the CPE of cells in all wells. Cell controls should be natural and have no cell fusion; Cells in the virus control wells should exhibit signs of virus cytopathology (giant cell formation, syncytia). Six µl of cell counting kit-8 reagent (CCK-8, Dojindo Molecular Technologies Inc., CK04-20) are added to each well, which allows colorimetric assays to determine the number of viable cells through the dehydrogenase activity detection. After 3-4 hour incubation, the absorbance of each well is measured with a spectrophotometric plate reader at 450 nm wavelength, using a 630 nm filter as background according to manufacturer’s instruction. The 50% effective concentration (EC ) is calculated by using regression analysis, based on the mean O.D. at each concentration of compound.

Standard reactions were incubated in 96-well plate format for 2 h at 30 °C, in the presence of increasing concentration of inhibitor. The reaction was stopped with 90 µL of 0.1M EDTA, and the reaction product was transferred to a "reading" 96-well plate.
After washing of the plate, radiolabeled RNA products were detected according to standard procedures with a Trilux Topcount scintillation counter. The compound concentration at which the enzyme-catalyzed rate was reduced by 50% (IC ) was calculated by fitting the data to a non-linear regression (sigmoidal). The IC values were derived from the mean of several independent experiments and are shown in Tables E and F.

To generate subgenomic RSV replicon, three glycoprotein genes, those for SH, G, and F, from a full-length recombinant GFP-expressing (rg) RSV antigenomic cDNA were deleted. In their place, a blasticidin S deaminase (bsd) gene was inserted. Through multiple steps, the RSV replicon was established in HeLa cells (395 Hela) or BHK cells (APC126). Both 395 HeLa and APC126 cells were cultured in Dulbecco’s Modified Eagle Medium (DMEM) containing 4500 mg/L D-glucose, L-glutamine, and 110 mg/L sodium pyruvate (Invitrogen, Cat. #11995-040). The medium was further supplemented with 10% (v/v) fetal bovine serum (FBS) (Mediatech, Cat. #35CV), 1% (v/v) penicillin/streptomycin (Mediatech, Cat. #30CI), and 10 μg/mL of Blasticidin (BSD) (Invivogen, Cat. code ant-bl-1). Cells were maintained at 37 C in a humidified 5% CO atmosphere.
Determination of 50% inhibitory concentration (EC ), 90% inhibitory concentration (EC ) and 50% cytotoxic concentration (CC ) in RSV replicon cells were 90 50 performed by the following procedure. On the first day, 5000 RSV replicon cells per well were plated in a 96-well plate. On the following day, compounds to be tested were solubilized in 100% DMSO to 100X the desired final testing concentration. Each compound was serially diluted (1:3) up to 9 distinct concentrations. Compounds in 100% DMSO were reduced to 10% (v/v) DMSO by diluting 1:10 in cell culture media. A 10 μL sample of the compounds diluted to 10% (v/v) DMSO with cell culture media was used to treat the RSV replicon cells in 96-well format. The final DMSO concentration was 1% (v/v). Cells were incubated with compounds for 7 days (for 395Hela) or 3 days (for APC126) at 37 C in a 5% CO2 atmosphere. In each assay, positive control that was previously characterized in the RSV replicon assay was included.
The Renilla Luciferase Assay System (Promega, Cat. #E2820) was used to measure anti-RSV replicon activity. Assay plates were set up as stated above.
Luminescence was recorded using a Perkin Elmer multilabel counter Victor3V. EC , the concentration of the drug required for reducing RSV replicon RNA by 50% in relation to the untreated cell control value, was calculated from the plot of percentage reductions of the optical density (OD) value against the drug concentrations using the Microsoft Excel forecast function. 395 HeLa or APC126 cell proliferation assay (Promega; CellTiter-Glo Luminescent Cell Viability Assay, Cat. #G7572) was used to measure cell viability. The CellTiter-Glo Luminescent Cell Viability Assay is a homogeneous method to determine the number of viable cells in culture based on quantitation of the ATP present, which signals the presence of metabolically active cells. Assay plates were set up in the same format as noted above for the replicon assay. CellTiter-Glo reagent (100 μL) was added to each well and incubated at room temperature for 8 minutes. Luminescence was recorded using a Perkin Elmer multilabel counter Victor3V. The CC , the concentration of the drug required for reducing viable cells by 50% in relation to the untreated cell control value, was calculated from the plot of percentage reductions of the luminescence value against the drug concentrations using the Microsoft Excel forecast function.

Martin Moore of Emory University, Atlanta, GA, USA. The in vitro viral kinetics of A2-RL- line19F is similar to that of wild type RSV (See Hotard, A.L., Virology (2012) 434(1):129– 136).
Host cell HEp-2 was purchased from ATCC (Cat. #CCL-23) and cells were cultured in DMEM/Ham’s F-12 50/50 1× containing L-glutamine and 15 mM HEPES (Mediatech, Cat. #10CM). The medium was further supplemented with 5% (v/v) FBS (Mediatech, Cat. #35CV) and 1% (v/v) penicillin/streptomycin (Mediatech, Cat. #30CI). HEp-2 cells were maintained at 37 °C in a humidified 5% CO atmosphere.
Drug Treatment and Viral Dosing To determine the effect of a combination of compounds, the following procedure was followed. On the first day, 20,000 HEp-2 cells were plated per well in a 96- well plate. On the following day, test articles were solubilized in 100% DMSO (for chemicals) or 1 x PBS (for biologics) to 200x the desired final testing concentration.
Subsequently, Compound (A), or a pharmaceutically acceptable salt thereof, was serially diluted (1:3) to 9 distinct concentrations "horizontally" in a 96-well plate, and Compound (B), or a pharmaceutically acceptable salt thereof, was serially diluted (1:3) to 7 distinct concentrations "vertically" in 96-well plate. The serially diluted 200x test articles were then diluted 1:10 into cell culture media to generate 20x test articles. A 5 μL aliquot of the 20x test articles was added in a checkerboard fashion to the cells with 90 L existing media.
Space was also allotted for titrations of each of the compounds alone to be used as reference controls. After 12 hour pre-incubation of test articles, A2-RL-line19F at an MOI of 0.5 was added to the plate and further incubated for 2 days at 37 °C in a 5% CO .
Determination of Anti-RSV Activity The Renilla Luciferase Assay System (Promega, Cat. # E2820) was used to measure anti-RSV replicon activity. Assay plates were set up as stated above.
Luminescence was recorded using a Perkin Elmer multilabel counter Victor3V.
Cell Viability Assay Promega CellTiter-Glo Luminescent Cell Viability Assay, Cat. #G7572) was used to measure cell viability. The CellTiter-Glo Luminescent Cell Viability Assay is a homogeneous method to determine the number of viable cells in culture based on quantitation of the adenosine triphosphate (ATP) present, which signals the presence of metabolically active cells. Assay plates were set up in the same format the anti-RSV assay, except that no virus was added to the cell viability assay. A 100-μL aliquot of CellTiter-Glo reagent was added to each well and incubated at room temperature for 8 minutes.
Luminescence was recorded using a Perkin Elmer multilabel counter Victor3V.
Data Analysis Each experiment was performed at N=5 for both anti-RSV activity and cell viability. Mean percent inhibition of the replicon values from the 5 experiments was generated and for anti-RSV activity, it was analyzed using two drug interaction analysis models, Isobologram Analysis and/or Prichard’s Model.
Isobologram Analysis The effects of drug-drug combinations were evaluated by the Loewe additivity model in which the experimental data were analyzed using CalcuSyn (Biosoft, Ferguson, MO), a computer program based on the method of Chou and Talalay. The combination index (CI) value and the isobologram for each experimental combination were calculated. CI values of <1, 1, and >1 indicate synergy, additive effect, and antagonism, respectively. Under the synergy category, CI<0.1 is considered very strong synergism; CI 0.1-0.3 strong synergism; CI 0.3-0.7 synergism and CI 0.7-0.85 moderate synergism. The isobologram analysis, which graphically represents additive, synergistic, and antagonistic drug effects, was also used to model the interaction of antiviral activities. In this representation, an effective concentration (EC) value of one drug is plotted on one axis and corresponding EC value of a second drug is plotted on the second axis; the line connecting these two points represents the amount of each drug in a combination that would be required to reach the equivalent EC value, given that their effects are additive.
Prichard’s Model (MacSynergy II) MacSynergy II software was kindly provided by Dr. M. Prichard (University of Michigan). This program allows the three-dimensional examination of drug interactions of all data points generated from the checkerboard combination of two inhibitors with Bliss-Independence model. Confidence bounds are determined from replicate data. If the 95% confidence limits (CL) do not overlap the theoretic additive surface, then the interaction between the two drugs differs significantly from additive. The volumes of synergy or antagonism can be determined and graphically depicted in three dimensions and represent the relative quantity of synergism or antagonism per change in the two drug concentrations. Synergy and antagonism volumes are based on the Bliss independence model, which assumes that both compounds act independently on different targets. A set of predicted fractional responses faAB under the Bliss independence model is calculated as faAB = faA + faB - faA• faB with faA and faB representing the fraction of possible responses, e.g. % inhibition, of compounds A and B at amounts dA and dB, respectively, and describes the % inhibition of a combination of compounds A and B at amount (dA+dB). If faAB > faA + faB - faA• faB then we have Bliss synergy; if faAB < faA + faB - faA• faB then we have Bliss antagonism. The 95% synergy/antagonism volumes are the summation of the differences between the observed inhibition and the 95% confidence limit on the prediction of faAB under the Bliss independence model. MacSynergy II was used for data analysis.
MacSynergy II Volume Descriptions: <25 M % = Additive; 25-50 2 2 2 M % = Minor synergism; 50-100 M % = Significant synergism; and >100 M % = Strong synergism. For the combination of 574 and BMS-433771 (a fusion protein inhibitor) had a synergy volume of 24.9 M % (additive/minor synergism).
EXAMPLE F Parainfluenza virus-3 (PIV-3) Plaque Assay MA-104 cells are grown in 24-well plates to a confluency of 90% in the presence of minimal essential medium (MEM) supplemented with 10% fetal bovine serum and antibiotics (C-EMEM). The cells are then washed twice with non-complete minimal essential medium (NC-EMEM). Test articles are dissolved in DMSO to a stock concentration of 10 mM.
An aliquot of 0.5 mL of the test article at various concentrations are then inoculated in triplicate wells and are incubated for 60 mins at 37 °C with 5% CO for the diffusion of test article into MA-104 cells. After the incubation period, a stock of human PIV type 3 are thawed and diluted with NC-EMEM to achieve a viral concentration of 10 pfu/mL. An aliquot of 0.1 mL are then inoculated into all the wells except for the negative and test article toxicity control wells. Upon infection, the plates are incubated for 72 h at 37 °C at 5% CO . After incubation, the plates are examined under microscopy to record cytotoxicity. The supernatants are collected for viral quantification using a standard plaque assay using MA-104 cells as the indicator cells.
To perform the plaques assay, MA-104 cells are grown to confluence in 24-well plates. The cells are washed with serum-free medium prior to inoculation of duplicate wells with serial 10-fold dilutions of supernatant sample. After 1 h incubation at 37 °C, the samples are aspirated and 1.0 mL of methyl cellulose overlay media are added to each well. After 6 days of culture, the cells are fixed and stained with 0.06% crystal violet in 1% glutaraldehyde and viral plaques are enumerated. The data are analyzed with Prism software with EC defined as drug concentration that reduced the viral load 50% from the viral control (VC).
EXAMPLE G Human metapneumovirus (hMPV) TCID Assay LLC-MK2 cells are grown in 24-well plates to a confluency of 90% in the presence of minimal essential medium (MEM) supplemented with 10% fetal bovine serum and antibiotics (C-EMEM). The cells are then washed twice with non-complete minimal essential medium (NC-EMEM). Test articles are dissolved in DMSO to a stock concentration of 10 mM.
An aliquot of 0.5 mL of the test article at various concentrations are then inoculated in triplicate wells and are incubated for 60 mins at 37 °C with 5% CO for the diffusion of test article into LLC-MK2 cells. After the incubation period, a stock of human metapneumovirus are thawed and diluted with NC-EMEM to achieve a viral concentration of pfu/mL. An aliquot of 0.1 mL are then inoculated into all the wells except for the negative and test article toxicity control wells. Upon infection, the plates are incubated for 7 days at 37 °C at 5% CO . After incubation, the plates are examined under microscopy to record cytotoxicity. The supernatants are collected for viral quantification using a standard TCID assay using LLC-MK2 cells as the indicator cells. The data are analyzed with Prism software with EC defined as drug concentration that reduced the viral load 50% from the viral control (VC).
