FIELD
Disclosed are methods for treating Vascular Leak Syndrome. Further disclosed are methods for treating vascular leakage due to inflammatory diseases, inter alia, sepsis, lupus, irritable bowel disease. Also disclosed are methods for treating vascular leakage due to the presence of pathogens. Yet further disclosed are methods for treating metastatic renal cell carcinoma and metastatic melanoma.
BACKGROUND
Vascular leak is characterized by hypotension, peripheral edema, and hypoalbuminemia. Vascular leak can occur as a side effect of illness especially illnesses due to pathogens, inter alia, viruses and bacteria. Vascular leak complicates the healing process and can itself be a direct result of certain therapies. For example, patients suffering from malignant renal carcinoma are given Interleukin-2 to help boost their immune system; however, this treatment must be withdrawn in many patients due to the onset of severe vascular leak well before the full course of treatment can be administered. Therefore, the cancer treatment is withdrawn earlier than desired and usually before the therapy is maximally effective. VLS restricts the doses of IL-2 which can be administered to humans and, in some cases, necessitates the cessation of therapy.
VLS is characterized by an increase in vascular permeability accompanied by extravasation of fluids and proteins resulting in interstitial edema and organ failure.
Manifestations of VLS include fluid retention, increase in body weight, peripheral edema, pleural and pericardial effusions, ascites, anasarca and, in severe form, signs of pulmonary and cardiovascular failure. Symptoms are highly variable among patients and the causes are

During the course of antiviral and antibacterial infections, patients can develop vascular leak that is induced as result of the initial infection. There is now a long felt need for a method of preventing vascular leak due to viral or bacterial infection, and therefore provide a method of increasing the survival of humans or other mammals infected with one or more pathogens. In addition, there is a long felt need for a method of preventing vascular leakage due to certain anticancer drugs or other anticancer therapies such that the administration of anticancer drugs or anticancer therapies can be given to humans or other mammals for a longer course of treatment or therapy.
SUMMARY
Disclosed herein are compounds that inhibit the intracellular catalytic site of protein tyrosine phosphatase beta (ΡΤΡ-β) molecule. ΡΤΡ-β is known only to be expressed in vascular endothelial cells. Inhibition of ΡΤΡ-β reduces the rate of dephosphorylaiion of the Tie-2 receptor tyrosine kinase. This inhibition results in amplification of the Angiopoietin 1 (Ang-1) signal through Tie-2, and effectively counters the inhibitory effects of Angiopoietin 2 (Ang-2) on Tie-2. Because Tie-2 is critical to maintaining vascular endothelial integrity, the disclosed ΡΤΡ-β inhibitors provide a method for providing vascular stabilization in humans and mammals. As such, the disclosed ΡΤΡ-β inhibitors provide Tie-2 signal amplification. One important manifestation of vascular de-stabilization is vascular leak syndrome (VLS) which has many causes, for example, infection of a human or mammal by a pathogen. Another common cause of vascular leak syndrome is the use of certain chemotherapeutic agents, inter alia, IL-2 which is used in treating certain forms of cancer.
Disclosed herein are methods for stabilizing human and mammalian vasculature. The stabilization of vasculature in patients compromised with an infection due to the presence of pathogens, inter alia, bacteria, vimses, yeasts, and fungi, provide a method for preventing complications due to infection such as sepsis, pulmonary edema, and the like, Subjects suffering from or diagnosed with certain cancers are given chemotherapeutic agents that result in vascular leak syndrome as a primary side effect causing cessation of treatment, before the desired full course has been achieved. For weakened humans and mammals, the onset of vascular leak syndrome due to one or more compromising events can be avoided by the disclosed methods for

Ranges may 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,
A weight percent 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.
By “effective amount” as used herein means “an amount of one or more of the disclosed Tie-2 signal amplifiers,: effective at dosages and for periods of time necessary to achieve the desired or therapeutic result.” An effective amount may vary according to factors known in the art, such as the disease state, age, sex, and weight of the human or animal being treated.
Although particular dosage regimes may be described in examples herein, a person skilled in. the art would appreciated that the dosage regime may be altered to provide optimum therapeutic response. For example, several divided doses may be administered daily or the dose may be proportionally reduced as indicated by the exigencies of the therapeutic situation. In addition, the compositions of this disclosure can be administered as frequently as necessary to achieve a therapeutic amount.
“Admixture” or “blend” is generally used herein means a physical combination of two or more different components “Excipient” is used herein to include any other compound that may be contained in or combined with one or more of the disclosed inhibitors that is not a therapeutically or biologically active compound. As such, an excipient should be pharmaceutically or biologically acceptable or relevant (for example, an excipient should generally be non-toxic to the subject). “Excipient” includes a single such compound and is also intended to include a plurality of excipients.
As used herein, by a “subject” is meant an individual. Thus, the “subject” can include domesticated animals (e.g., cats, dogs, etc.), livestock (e.g., cattle, horses, pigs, sheep, goats, etc.), laboratory animals (e.g., mouse, rabbit, rat, guinea pig, etc.), and birds. “Subject” can also include a mammal, such as a primate or a human.
By “reduce” or other forms of the word, such as “reducing” or “reduction,” is meant lowering of an event or characteristic (e.g., vascular leakage). It is understood that this is

2016203254 18 May 2016 typically in relation to some standard or expected value, in other words it is relative, but that it is not always necessary for the standard or relative value to he referred to.
By “prevent” or other forms of the word, such as “preventing” or “prevention,” is meant to stop a particular event or characteristic, to stabilize or delay the development or progression of a particular event or characteristic, or to minimize the chances that a particular event or characteristic will occur. Prevent does not require comparison to a control as it is typically more absolute than, for example, reduce. As used herein, something could be reduced but not prevented, but something that is reduced could also be prevented. Likewise, something could be prevented but not reduced, but something that is prevented could also be reduced. It is understood that where reduce or prevent are used, unless specifically indicated otherwise, the use of the other word is also expressly disclosed.
By “treat” or other forms of the word, such as “treated” or “treatment,” is meant to administer a composition or to perform a method in order to reduce, prevent, inhibit, breakdown, or eliminate a particular characteristic or event (e.g., vascular leakge). The disclosed compounds affect vascular leakage by inhibiting ΡΤΡ-β (and the rodent equivalent, VE-PTP) which enhances or amplifies Tie-2 signaling.
By “chemotherapeutic agent” is meant any drug, pharmaceutical or otherwise, that can be given to a subject as part of a combination therapy.

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 when a value is disclosed, then “less than or equal to” the value, “greater than or equal to the value,” and possible ranges between values are also disclosed, as appropriately understood by the skilled artisan. For example, if the value “10” is disclosed, then “less than or equal to 10” as well as “greater than or equal to 10” is also disclosed. It is also understood that throughout the application data are provided in a number of different formats and that this data represent endpoints and starting points and ranges for any combination of the data points. For example, if a particular data point “10” and a particular data point “15” are disclosed, it is understood that greater than, greater than or equal to, less than, less than or equal to, and equal to 10 and 15 are considered disclosed as well as between 10 and 15. 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.
The following chemical hierarchy is used throughout the specification to describe and enable the scope of the present disclosure and to particularly point out and distinctly claim the units which comprise the compounds of the present disclosure, however, unless otherwise specifically defined, the terms used herein are the same as those of the artisan of ordinary skill. The term “hydrocarbyl” stands for any carbon atom-based unit (organic molecule), said units optionally containing one or more organic functional group, including inorganic atom comprising salts, inter alia, carboxylate salts, quaternary ammonium salts. Within the broad meaning of the term “hydrocarbyl” are the classes “acyclic hydrocarbyl” and “cyclic hydrocarbyl” which terms are used to divide hydrocarbyl units into cyclic and non-cyclic classes.
As it relates to the following definitions, “cyclic hydrocarbyl” units can comprise only carbon atoms in the ring (i.e.. carbocyclic and aryl rings) or can comprise one or more

The vessel is filled with and the vessel is shaken under 40 psi H2 for -40 hr. The vessel is evacuated and the atmosphere is purged with N2 (5 x 20 psi). An aliquot is filtered and analyzed by HPLC to insure complete conversion. The suspension is filtered through a pad of celite to remove the catalyst, and the homogeneous yellow filtrate is concentrated by rotary evaporation to afford 16.06 g (95% yield) of the desired product as a tan solid, which is used without further purification.
Preparation of4-((IS)-2-((5)-2-(methoxycarbonyl)-3-phenylpropanamido)-2-(2ethylthiazol-4-yl) ethyljphenylsulfamic acid (13): A 100 mL RBF is charged with {1-(2-(5)-(4(5)-aminophenyl)-l -(2-ethylthiazol-4-yl)ethyl-carbamoyl]-2-phenylethyl}-carbamic acid methyl ester, 12a, (10.36 g, 22.9 mmol, 1.0 eq.) prepared in the step described herein above.
Acetonitrile (50 mL, 5 mL/g) is added and the yellow suspension is stirred at room temperature. A second 3-necked 500 mL RBF is charged with SO3· pyr (5.13 g, 32,2 mmol, 1.4 eq.) and acetonitrile (50 mL 5 mL/g) and the white suspension is stirred at room temperature. Both suspensions are gently heated until the reaction solution containing {1-(2-(5)-(4-(5)aminophenyl)-l~(2~ethylthiazol-4-yl)ethy!-earbamoyl]-2-phenylethyl)-carbamic acid methyl ester becomes red-orange in color (typically for this example about 44 °C), This substrate containing solution is poured in one portion into the stirring suspension of SOy pyr at 35 °C.
The resulting opaque mixture (39 °C) is stirred vigorously while allowed to slowly cool to room temperature. After stirring for 45 min, the reaction is determined to be complete by HPLC. H2O (200 mL, 20 mL/g) is added to the orange suspension to provide a yellow-orange homogeneous solution having a pH of approximately 2,4, Concentrated H3PO4 is added slowly over 12 minutes to lower the pH to approximately 1.4. During this pH adjustment, an off-white precipitate is formed and the solution is stirred at room temperature for 1 hr. The suspension is filtered and the filter cake is washed with the filtrate. The filter cake is air-dried on the filter overnight to afford 10.89 g (89 % yield) of the desired product as a fan solid.

EXAMPLE 7 [ I -(S)-(P heny ] thiazoI-2-y I)~2~(4~su tins minopheny I)ethyl ] eartmmie acid tert-butyl ester (19)
Preparation of [2-(4-nitrophenyl)-l-(5)-(4-phenylthiazol-2-yl)ethyl]-carbamic acid tertbutyl ester (18): A mixture of [2-(4-nitrophenyl)-l-(5)-thiocarbamoyiethylj-carbamic acid tertbutyl ester, 2, (0.343 g, 1.05 mmol), 2-bromoacetophenone (0.231 g, 1.15 mmol), in CH3CN (5 mL) is refluxed 1.5 hour. The solvent is removed under reduced pressure and the residue redissolved in CHjCh then pyridine (0.24 mL, 3.0 mmol) and Boe?O (0.24 mL, 1.1 mmol) are added. The reaction is stirred for 2 hours and diethyl ether is added to the solution and the precipitate which forms is removed by filtration. The organic layer is dried (NazSO^), filtered, and concentrated to a residue which is purified over silica to afford 0.176 g (39%) of the desired product ESI+ MS 426 (M+l).
Preparation of [l-(S)-(phenylthiazol-2-yl)-2-(4-suIfoaminophenyl)ethyi]carbamic acid tert-butyl ester (19): [2-(4-nitrophenyl)-l-(S)-(4-phenyithiazol-2-yi)ethyi]carbamic acid tert-butyl ester, 18, (0.176 g, 0.41 mmol) is dissolved in MeOH (4 mL). A catalytic amount of Pd/C (10% w/w) is added and the mixture is stirred under a hydrogen atmosphere 12 hours. The reaction mixture is filtered through a bed of CELITE™ and the solvent is removed under reduced pressure. The crude product is dissolved in pyridine (12 mL) and treated with SOj-pyridine (0.195 g, 1.23 mmol). The reaction is stirred at room temperature for 5 minutes after which a 7% solution of NH4OH (10 mL) is added. The mixture is then concentrated and the resulting residue is purified by reverse phase chromatography to afford 0.080 g of the desired product as the ammonium salt, 3H NMR (300 MHz, MeOH-iL) 8 7.93 (d,

Preparation of Ά7~[ 1 -(4-ethylthiazol-2-yl)-2-(4-nitrophenyi)ethyl]-2-phenyl-acetamide (20): To a solution of l-(S)-(4-ethy1thiazol-2-yI)-2-(4-nitrophenyl)ethyl amine hydrobromide, 3, (0.393 g, 1.1 mmol), phenylacetic acid (0.190 g, 1.4 mmol) and 1-hydroxybenzotriazole (HOBt) (0.094 g, 0.70 mmol) in DMF ( 10 mL) at 0°, is added l-(3-dimethylaminopropyl)-3ethylcarbodiimide (EDCI) (0.268g, 1.4 mmol) followed by triethylamine (0.60 mL, 4.2mmol·). The mixture is stirred at 0 °C for 30 minutes then at room temperature overnight. The reaction mixture is diluted with water and extracted with EtOAc. The combined organic phase is washed with 1 N aqueous HCI, 5 % aqueous NaHCOj, water and brine, and dried over NajSCri. The solvent is removed in vacuo to afford 0.260 g (60 % yield) of the desired product which is used without further purification. ES1+ MS 396 (M+l).
Preparation of {4-[2-(5)-(4-ethyithiazol-2-yl)-2-(2-phenylacetylamido)ethyl]phenyljsulfamic acid (21): Ar~[l-(4-ethylthiazol-2-yi)-2-(4-nitrophenyl)ethyl]-2-phenylacetamide, 20, (0.260 g) is dissolved in MeOH (4 mL). A catalytic amount of Pd/C (10% w/w) is added and the mixture is stirred under a hydrogen atmosphere 18 hours. The reaction mixture is filtered through a bed of CELITE™ and the solvent is removed under reduced pressure. The crude product is dissolved in pyridine (12 mL.) and treated with SO3-pyridine (0.177 g, 1.23).
The reaction is stirred at room temperature for 5 minutes after which a 7% solution of NH4OH (10 mL) is added. The mixture is then concentrated and the resulting residue is purified by reverse phase chromatography to afford 0.136 g of the desired product as the ammonium salt.

METHODS
The vascular endothelium lines the inside of all blood vessels, forming a nonthrombogenic surface that controls the entry and exit of plasma and white blood cells to and from the bloodstream. The quiescent endothelium has turnover rates of months to years, and proliferates only following angiogenic activation. The loss of endothelial quiescence is a common feature of conditions such as inflammation, atherosclerosis, restenosis, angiogenesis and various types of vasculopathies,
Vasculogenesis and angiogenesis are down-regulated in the healthy adult and are, except for the organs of the female reproductive system, almost exclusively associated with pathology when angiogenesis is induced by microenvironmental factors such as hypoxia or inflammation. These pathological processes associated with, or induced by, angiogenesis include diseases as diverse as cancer, psoriasis, macular degeneration, diabetic retinopathy, thrombosis, and inflammatory disorders including arthritis and athrerosclerosis. However, in certain instances insufficient angiogenesis can lead to diseaeses such as ischemic heart disease and pre-eclampsia.
The quiescent vascular endothelium forms a tight barrier that controls the passage of plasma and cells from the bloodstream to the underlying tissues, Endothellial cells adhere to each other through junctional transmembrane proteins that are linked to specific intracelllar structural and signaling complexes. The endothelial layer can undergo a transition from the resting state to the active state wherein activation of the endothelium results in the expression of adhesion molecules. This endothelium activation is a prerequisite for initiating angtogensesis, inflammation and inflammation associated diseases,
Tie-2, a receptor-like tyrosine kinase exclusively expressed in endothelial cells that controls endothelial differentiation. Tie-2 binds and is activated by the stimulatory ligand angiopoeitin-1 (Ang-1) which promotes autophosphorylation of the Tie-2 receptor leading to a cascade of events that results in stabilization of vascular structures by promoting endothelial cell

2016203254 18 May 2016 viability and preventing basement membrane dissolution. As such, Tie-2 activation is a method for attenuating leaking vasculature by maintaining a quiescent, intact vascular endothelium.
Tie-2 activation is inhibited by Ang-2, which exhibits Ang-1 antagonism by competitively binding fo Tie-2 and thus blocking phosphorylation of Tie-2. Elevated levels of Ang-2 have been found to be associated with infiammatoiy diseases, inter alia, sepsis, lupus, irritable bowel disease and metastatic diseases such as cancer,
During periods of high Ang-2 levels, fissures or breaks in the endothelium form which results in vascular leak syndrome. Vascular leak syndrome results in life-threatening effects such as tissue and pulmonary edema. For many disease states elevated Ang-2 levels are clear markers that a disease state or condition exists. Once a disease state has been resolved, the Angl/Ang-2 balance returns and the vascular endothelium is stabilized.
Amplification of Tie-2 Signaling
In conditions wherein the normal balance between Ang-1 and Ang-2 has been disrupted, the disclosed compounds have been found to amplify Tie-2 signaling by inhibiting dephosphorylation of phosphorylated Tie-2 via inhibition of Human Protein Tyrosine Phosphatase-β (ΗΡΤΡ-β). In addition, the disclosed compounds can be used in varying amounts to increase the Tie-2 signaling in a very controlled manner, and to therefore titrate the level of Tie-2 amplification,
IL-2 Induced Vascular Leak: Treatment of Metastatic Cancers
Immunotherapy is one method of treating cancer. Up-regulation of the body’s own immune system is one aspect of immunotherapy. Among the many immune system signaling molecules is interleukin-2 (IL-2) which is instrumental in the body’s natural response fo microbial infection and in discriminating between foreign (non-self) and self. High-dose interleukin-2 (HDIL-2) is an FDA approved treatment for patients with metastatic renal cell carcinoma (RCC) and metastatic melanoma. Although it has been reported that only 23% of those subjects given this therapy show a tumor response, the duration of this response can exceed 10 years (Elias L. et al., “ A literature analysis of prognostic factors for response and quality of response of patients with renal cell carcinoma to interleukin-2-based therapy.” Oncology (2001); 61: pp. 91-101). As such, IL-2 therapy is the only available treatment that offers the potential for cure.

Gallagher (Gallagher, D.C. et al.f “Angiopoietin 2 Is a Potential Mediator of High-Dose Interleukin 2-Induced Vascular Leak” Clin Cancer Res (2007):13(7) 2115-2120) reports that elevated levels of angiopoietin-2 are found in patients treated with high doses of IL-2 and suggests that overcoming Ang-2 blockade of Tie-2 signaling might be curative for vascular leak syndrome which is a side effect of this therapy. As many as 65% of patients receiving this IL-2 therapy will necessarily interrupt or discontinue treatment due to VLS. VLS is typicallycharacterized by 2 or more of the following 3 symptoms (hypotension, edema, hypoalfaummemia), although other manifestations include prerenal azotemia, metabolic acidosis, pleural effusions, and non-cardiogenic pulmonary edema.
IL-2 is known to cause endothelial cell activation, however, with loss of proper barrier function. Amplification of Tic-2 signaling during High Dose IL-2 immunotherapy would lead to attenuation of vascular leakage since Tie-2 stimulation promotes endothelial cell stability. As such, by administering an agent that can amplify Tie-2 signaling, vascular stability can be increased and, hence, the side effects of high IL-2 dosing mitigated. The disclosed compounds can amplify Tie-2 signaling under the conditions of low angiopoietin-1 concentrations or when high concentrations of angiopoietin-2 are present as in IL-2 treated patients.
By amplifying Tie-2 signaling without affecting Ang-2 levels, the use of elevated levels of Ang-2 as a potential pathology marker is retained. For example, a patient suffering from an inflammatory disease such as sepsis will normally have an elevated Ang-2 level that acts to suppress Ang~l stimulation of Tie-2. This elevated Ang-2 results in edema which is a symptom of vascular leakage. The present methods, by amplifying Tie-2 signaling without affecting the Ang-2 level, provide a method for alleviating the symptoms that are associated with vascular leak while retaining the ability to use Ang-2 levels as a measure of disease progress and resolution.
Reduction of Vascular Leak Caused by an Anticancer Therapy
The following demonstrates the effectiveness of the disclosed compounds on Tie-2 signal amplification, and thus, the alleviation of vascular leakage due to administration of high doses of an anticancer treatment that induces vascular leak syndrome, i.e., IL-2.
Twenty-five mice were used for the following experiment. Five are selected as the control and received no treatment. The remaining twenty mice were divided into four groups of five mice each and dosed as follows over a period of 5 days:

was used as the Tie-2 signal amplifier. As depicted in Figure 1 the blood pressure of the animals treated with a high dose of IL-2 went to 0 mm Hg (death), whereas the animals treated with4-{(S)-2-[(5)-2-(methoxycarbonylamino)-3-phenyl-propanamido)-2-(2-(thiophen.-2yl)thiazoi-4-yl]ethyI}phenylsuifamic acid ammonium salt showed little effect on blood pressure even in the case of those animals treated with the high dose of IL-2.
As depicted in Figure 2, of the animals receiving high doses of IL-2, 60% showed clinical symptoms of shock, whereas the animals receiving high doses of IL-2 and the Tie-2 signal amplifier 4-{(S)-2-[(iS)-2-(methoxycarbonylamino)-3-phenyl-propanamido]-2-[2~ (thiophen-2-yl)thiazol-4-yl]ethyl)phenylsulfamic acid ammonium salt showed no signs of shock.
As depicted in Figure 3, of the animals receiving high doses of IL-2, 40% died, whereas the animals receiving high doses of IL-2 and the Tie-2 signal amplifier 4-((5)-2-((5)-2(methoxycarbonylamino)-3-phenyl-propanamido]-2-[2-(thiophen-2-yl)thiazol-4yl]ethyl}phenylsulfamic acid ammonium salt survived.

Tumor growth is often a multi-step process that starts with the loss of control of cell proliferation. The cancerous cell then begins to divide rapidly, resulting in a microscopically small, spheroid tumor: an in situ carcinoma. As the tumor mass grows, the cells will find themselves further and further away from the nearest capillary. Finally the tumor stops growing and reaches a steady state, in which the number of proliferating cells counterbalances the number of dying cells. The restriction in size is caused by the lack of nutrients and oxygen. In tissues, the oxygen diffusion limit corresponds to a distance of 100 pm between the capillary and the cells, which is in the range of 3-5 lines of cells around a single vessel. In situ carcinomas may remain dormant and undetected for many years and metastases are rarely associated with these small (2 to 3 mm2), avascular tumors.
When a tumor’s growth is stopped due to a lack of nutrients and/or oxygen, this reduction In tumor vasculature also limits the ability of anti-tumor drugs to be delivered to the malignant cells. Moreover, if there is a slight increase in tumor vasculature, this will allow delivery of antitumor therapies to the malignant cells without initiating metastasis. As such, the disclosed compounds when used to slightly amplify Tie-2 signaling can be used to increase blood flow to the tumor cells without setting off metastasis or uncontrolled tumor cell proliferation while providing a method for delivering anti-cancer drugs to malignant cells.

Alternatively, the level of Ang-2 can be determined for an individual suffering from a disease state, for example, severe sepsis and the level of Ang-2 can be monitored until the amount of Ang~2 in the subject’s serum drop to a level that is nearer the normal range. In this case, the co-administration of a drug can be continued or discontinued. Therefore, disclosed herein, is a method for stabilizing the vasculature of a subject during a course of treatment, comprising:
a) co-administering to a subject an effective amount of one or more of the disclosed compounds and one or more drugs as a treatment;
b) monitoring the level of angiopoietin-2 present in the subject; and
c) discontinuing the administration of the one or more drugs and selecting one or more other drags for use as a treatment if the level of serum angiopoetin-2 does not decrease.
The disclosed compounds, while stabilizing the vasculature of a patient such that a course of treatment against a pathogen can be sustained, can also be used to stabilize a subject during a period wherein an effective treatment against a pathogen is being determined. That is, the disclosed compounds by themselves can have a beneficial effect on the outcome of diseases caused by pathogens by reducing vascular leak and its complications,
Liposacehnride Induced Vascular Leak Model
The following liposaccharide induced vascular leakage model can be used to confirm the ability of the disclosed compounds to decrease the effects of vascular leak syndrome caused by pathogens. In the following example acute kidney injury (AKI) was studied to show the effect of D91 as a successful strategy that can preserve renal endothelial Tie2 phosphorylation in septic AKI.
Acute kidney injury is a frequent and serious problem in hospitalized patients, and is frequently a consequence of sepsis. The renal endothelium plays a key role in sepsis induced AKI. Activated Tie2, expressed mainly in endothelial cell surfaces, has many effects which are expected to be protective in sepsis-induced AKI, such as downregulation of adhesion molecule expression, inhibition of apoptosis, preservation of barrier function, and angiogenesis.
Male C57BL6 mice, 9 to 10 weeks old, were injected i.p. with 0.2 mg E, Coii lipopolysaccharide per 25 g body weight at time 0. Mice were injected with D91 at 50 mg/kg, 50

2016203254 18 May 2016 μΕ versus vehicle (50 μΕ) at the time 0, 8, and 16 hours.. Mice were sacrificed at 24 hours after
LPS injection. Vehicle control (saline) injected mice were studied in parallel as controls. Serum samples were analyzed for blood urea nitrogen (BUN) as a marker of kidney function.
As shown in Figure 7, the level of blood urine nitrogen (BUN) in the animals receiving only LPS (ri) was approximately 150 mg/dL at 24 hours, whereas animals treated with 50 mg/kg of D91(«) had a blood urine nitrogen level of less than 80 mg/dL. These data show that D91is capable of protecting mice against AKI in this model.
Tissue samples from the animals were analyzed by high powered field microscopy to determine the number of polymorphonuclear leukocytes present. As shown in Figure 8, the number of PMN cells present in the LPS/vehicle animals was on average 26 whereas the number of PMN cells present in animals receiving D91 was on average 12. As such, this model demonstrates the effectiveness of D91 in preventing acute kidney injury due to pathogens, i.e., E. coli.
Phosphatase inhibition by the disclosed ΡΤΡ-β inhibitors reduces LPS-induced renal vascular leak. Mice were injected with LPS at time 0 and D91 or vehicle at 1,6, and 16h. Two minutes prior to sacrifice at 24 hours 70kDa. fluorescent fixable dextrans were administered by intravenous catheter. Frozen sections showed extrusion of dye beyond the small peritubular capillaries was induced by LPS, but is reduced by D91. Figure 10a is a micrograph of the control sample for the 70 kDa sample wherein the Letter “G” represents glomerular capillaries where the dye should normally be contained. Figure 10b represents a renal section taken from an LPS treated animal and Figure 10c represents a renal section taken from an animal treated with LPS and D91.
The following are non-limiting examples of virsus, bacteria, and other pathogens where virulence can be controlled by mitigating the degree of vascular leak that is induced by the organism. The following describe tests and assays that can be used to determine the effectiveness of the disclosed compounds, either alone, or a combination therapy,
ANTHRAX
Anthrax, the disease caused by Bacillus anthracis, was once a disease commonly spread among animals, but there is now a concern that this disease will be used as a part of bioterrorism. Inhalation anthrax is a deadly disease for which there is currently no effective treatment.
Anthrax toxin, a major virulence factor of this organism, consists of three polypeptides:

2016203254 18 May 2016 protective antigen (PA), lethal factor (LF), and edema factor (EF). PA is required for binding and translocation of EF and LF into target cells (Collier R, J, el al., (2003) Anthrax toxin, Arant. Rev. Cell Dev. Biol. 19:45-70). As such, lethal factor metalloproteinase is an integral component of the tripartite anthrax lethal toxin that is essential for the onset and progression of anthrax. The injection of lethal toxin (LT is LF plus PA) into animals is sufficient to induce some symptoms of anthrax infection, including pleural effusions indicative of vascular leak and lethality (Beall F. A. el al. (1966) The pathogenesis of the lethal effect of anthrax toxin in the rat. J. Infect. Dis.
116:377-389; Beall F. A. etal., (1962) Rapid lethal effect in rats of a third component found upon fractionating the toxin of Bacillus anthracis. J. Bact&riol. 83:1274-1280; Cui X. et al., (2004) Lethality during continuous anthrax lethal toxin infusion is associated with circulatory shock but not inflammatory cytokine or nitric oxide release in rats. Am. J, Physiol, Regul. Integr. Comp. Physiol. 286:R699-R709; Fish D. C, etal., (1968) Pathophysiological changes in the rat associated with anthrax toxin, J. Infect, Dis. 118:114-124; Klein F. et al., (1962) Anthrax toxin: causative agent in the death of rhesus monkeys. Science 138:1331-1333; Klein, F. el al., (1966) Pathophysiology of anthrax.,/. Infect. Dis. 116:123-138; and Moayeri M. et al,, (2003) Bacillus anthracis lethal toxin induces TNF-α-independent hypoxia-mediated toxicity in mice. J. Clin. Investig. 02:670-682), Early studies of anthrax suggested that lethal toxin kills animals by inducing nonspecific shock-like manifestations, and recent studies with mice and rats have confirmed an LT-mediated cytokine-independent vascular collapse. It has been reported that humans and primates exposed to spores via aerosol, present pleural effusions as the most common symptom of disease. Histopathological analyses of human subjects with inhalational anthrax infections display hemorrhaging in various organs resulting from destruction of both large and small vessels. Clearly, LT is an important virulence factor and contributes to some but not all the pathology observed with spore infection.
Recently, LT-mediated endothelial cell killing has been proposed to contribute to the vascular pathology observed during the course of anthrax (Kirby, J. E, (2004) Anthrax lethal toxin induces human endothelial ceil apoptosis, Infect, hnmim. 72:430-439). Since this LTinduced endothelial cytotoxicity occurs gradually (over 72 hours) and death from LT-mediated vascular collapse can occur in as little as 45 min (Ezzell J. W, et al., (1984)

In Vivo Vascular Leak
The Miles assay (Mites, A. A., and E. M, Mites (1952) Vascular reactions to histamine, histamine-liberator and leukotaxine in the skin of guinea-pigs. J. Physiol. 118:228-257 incorporated herein by reference in its entirety) can be used to directly investigate and quantify lethal toxin, as well as edema toxin (ET [PA plus EF])-mediated vascular leakage in the mouse model. The following is a modified Miles assay as described by Gozes Y, et al., Anthrax Lethal Toxin Induces Ketotifen-Sensitive Intradermal Vascular Leakage in Certain Inbred Mice Infect Immun. 2006 February; 74(2): 1266-1272 incorporated herein by reference in its entirety, that can be used to evaluate the disclosed compounds for their ability to prevent vascular leakage in humans and animals exposed to anthrax.
Highly pure PA, LF, and mutant LF E687C are purified as previously described (Varughese M, et aL, (1998) Internalization of a Bacillus anthracis protective antigen-c~Myc fusion protein mediated by cell surface anti-c-Myc antibodies. Mol. Med. 4:87-95 Included herein by reference in its entirety). Doses of ET or LT refer to the amount of each component (i.e,, 100 pg LT is 100 pg PA plus 100 pg of LF). All drugs except for azelastine can be purchased from Sigma Aldrich (St. Louis, MO); azelastine can be purchased from LKT Laboratories (St. Paul, MN),

BALB/c nude, C57BL/6J nude, and C3H hairless (Ci .Qg/TifBomTac~hf) mice can be purchased from Laconic Farms (Germantown, NY). C3H nude mice can be purchased from The National Cancer Institute Animal Production Area (Frederick, MD). Mice are used when they are 8 to 12 weeks old. Except for C3H hairless and nude animals, all mice are shaved 24 hours prior to intradermal (i.d.) injections. In order to assess the susceptibility to systemic LT. mice are injected intraperitoneally (i.p.) with 100 pg LT and observed over 5 days for signs of malaise or death. Fischer 344 rats can be purchased from Taconic Farms (Germantown, NY) and used at weights of 150 to 180 g. Rats are injected intravenously (i.v.) in the tail vein with 12

Miles Assay.
'The Miles assay uses i.v. injection of Evans blue dye (which binds to endogenous serum albumin) as a tracer to assay macromolecular leakage from peripheral vessels after i.d. injection of test substances. Nude mice and normal shaved mice are injected i.v, with 200 μΐ of 0.1% Evans blue dye (Sigma Chemical Co., St. Louis, MO). After 10 min, 30 μΐ of test toxin or control samples (PA only, LF only, EF only, or phosphate-buffered saline) are injected i.d. in both left and right flanks, as well as at single or dual dorsal sites. To quantify the extents of leakage, equally sized (1.0- to 1.5-cm diameter) skin regions surrounding i.d. injection sites are removed 60 min after injection and placed in formamide (1 ml) at 4FC for 48 h, allowing for dye extraction. The of samples is read, and the extent of leakage is calculated by comparison with phosphate-buffered saline-, PA-, or LF-treated controls.
In experiments wherein the effectiveness of the disclosed compounds are tested for LTmediated leakage, mice are injected i.v. with Evans blue as described above, and the test compound introduced systemically through i.p. injection 10 min after dye injection, LT was introduced by i.d. injection 30 min after the injection of Evans blue. In another embodiment, the compound to be tested can be introduced locally by i.d. injection and LT injected in the same site after 10 min.
Cytotoxicity eExperiments.
MC/9 mast cells can be obtained from ATCC (Manassas, VA) and grown In Dulbecco’s modified Eagle's medium supplemented with 1-glutamine (2 mM), 2-mercaptoethanol (0.05 mM), Rat T-STIM (BD Biosciences-Discovery Labware, Bedford, MA) (10%), and fetal bovine serum (FBS, 10% final concentration; Invitrogen-GIBCO BRL, Gaithersburg, MD). Cells are then seeded at a density of lQ4/weil in 96-weIl plates prior fo treatment with various LT concentrations or PA-only controls. After 6, 12, and 24 hours, viability is assessed using Promega's CellTiter 96 AQueous One Solution cell proliferation assay (Promega, Madison, Wl) per the manufacturer's protocol. Alternatively, toxicity assays can be performed in medium provided with all supplements except FBS (serum-free medium). In other embodiments, pooled human umbilical vein endothelial cells (HUVECs) at third to fifth passage can be obtained from Cambrex Corp, (Cambrex, Walkersville, MD) and grown in an EGM-MV Bulletkit (Cambrex,

Walkersville, MD) in flasks pretreated with endothelial cell attachment factor (Sigma, St. Louis, MO). For cytotoxicity experiments, cells are typically seeded in 96-well plates in an EGM-MV Bulletkit. On the day of assays, this medium is then replaced with Ml 99 medium (Sigma, St. Louis, MO) supplemented with 10% FBS or human serum (Sigma, St. Louis, MO), and cells are reseeded in 96-well plates at a density of 2 χ 1,070.1 ml/well and treated with various concentrations of LT in triplicate. Cell viability is typically assessed as for MG9 cells at 24, 48, and 72 hour time points.
HUVEC Permeability Assay
HUVEC monolayers can be effectively cultured on Transwell-Clear cell culture inserts (6.5-mm diameter, 0.4~pm pore size; Corning-Costar, Acton, MA) in 24-weli plates, creating a two-chamber culturing system consisting of a luminal compartment (inside the insert) and a subluminal compartment (the tissue culture plate well). Prior to seeding cells, the inserts are coated with endothelial cell attachment factor (Sigma, St. Louis, MO). Prewarmed CS-C medium (Sigma, St. Louis, MO) containing 10% iron-supplemented calf serum and 1% endothelial cell growth factor (Sigma, St. Louis, MO) is added to wells prior to insert placement. A HUVEC cell suspension (200 pL of 5 A·. 10s cells/ml) is then added to each insert. Ceils are cultured at 37 *C in 5% CO;, for up to 21 days to ensure proper formation of a monolayer. For testing barrier function, medium can be changed to RPMI supplemented with 10% FBS or to RPMI without serum. To assess barrier function, horseradish peroxidase enzyme (Sigma, St. Louis, MO) is added to the inserts (10 pg/well). LT (1 gg/mL) or control treatments of PA alone (1 pg/mL) or LF alone (1 pg/mL) are added to duplicate wells, and every hour (for 12 hours), a sample of 10 pL was taken from the subtuminal compartment and tested for the enzymatic activity of horseradish peroxidase by adding 100 pL substrate [2',2'-azino-bis(3-ethylbenzthizoHn 6sulfonic acid)] (A-3219; Sigma, St. Louis, MO) and reading at 405 nm.
Anthrax Combination Therapy
Increased stabilization of vascular tissue c an increase the effectiveness of known antimicrobials against anthrax infection. As such, the disclosed compounds can be evaluated as a combination therapy for the treatment of anthrax. The following describes a series of assays that can be used to determine the effectiveness of the disclosed compounds as one part of a combination therapy useful for treating anthrax infections.

LF has been found to cleave mitogen-activated protein kinase kinases (MAPKK), disrupts signal transduction, and leads to macrophage lysis. As such, in addition to the Miles
Assay, the following cell-based and peptide cleavage assay can be used to confirm the potency of the disclosed compounds to inhibit the effect of LT activity. For the following assay,
MAPKKide can be purchased from List Biological Laboratories (Campbell, CA. Fluorinated peptide substrate is available from Anaspec (San Jose, CA).
In Vivo Assays
One week before beginning an evaluation of a combination course of treatment for anthrax, test compounds (200 mg each) are dissolved in 800 pL of DMSO and stored at -20 °C. Immediately before injection, each compound is diluted in PBS, resulting in a final concentration of 0.5 rtig/mL in 2% DMSO. Test animal are challenged on day 0 with 2x10' spores per mouse in PBS through i.p. injection. Treatment was started 24 hours after challenge. One example of a suitable treatment regiment is the combination of ciprofloxacin (50 mg/kg) and one or more of the disclosed compounds (5 mg/kg), A control sample of untreated animals, ciprofloxacin alone, a disclosed compound alone, and ciprofloxacin in combination with a disclosed compound are given to the animals and they are monitored twice per day until day 14 after injection.
Ciprofloxacin and the compound to be tested can be conveniently administered through parenteral injection with a volume of 200 gL for each once per day for 10 days. All surviving animals are sacrificed on day 14. Sick animals that appear moribund (i.e., exhibiting a severely reduced or absent activity or locomotion level, an unresponsiveness to external stimuli, or an inability to obtain readily available food or water, along with any of the following accompanying signs: ruffled haircoat, hunched posture, inability to maintain normal body temperature, signs of hypothermia, respiratory distress, or other severely debilitating condition) should be sacrifice on the same day these symptoms are manifested.
Modulation of Bacterium-Induced Vascular Leak
Pathogenic bacteria are known to cause vascular leak. This induced vascular leakage inhibits the ability of antimicrobials and other pharmaceuticals from targeting the invading microorganism. As such, the disclosed compounds can be used alone or in combination with other pharmaceutical ingredients to boost the host immune system by preventing excess vascular leakage that occurs as a result of a bacterial infection.

Staphylococcus aureus is a major pathogen of gram-positive septic shock and is associated with consumption of plasma kininogen. The effect of the disclosed compounds on S'.
aureus induced vascular leakage activity can be determined by measuring the activity of these compounds with respect to two cysteine proteinases that are secreted by S. aureus.
Proteolytically active staphopain A (ScpA) induces vascular leakage in a bradykinin (BK) B2receptor-dependent manner in guinea pig skin. This effect is augmented by staphopain B (SspB), which, by itself, had no vascular leakage activity. ScpA also produces vascular leakage activity from human plasma.
An important pathophysiologic mechanism of septic shock is hypovolemic hypotension that is caused by plasma leakage into the extravascular space. It has been found that ScpA induced vascular leakage at a concentration as low as 20 nM within 5 minute after in jection, into the guinea pig skin—-with the reaction being augmented by coexisting SspB indicating that vascular leakage induction by these proteinases occurs efficiently in vivo (Imamura T. et al., Induction of vascular leakage through release of bradykinin and a novel kinin by cysteine proteinases from Staphylococcus aureus (2005) J. Experimental Medicine 201:10, 1669-1676).
Staphopains also can act on LK--whose plasma molar concentration has been found to be threefold greater than HK—they also have more opportunity to interactwith substrate than proteinases that generate BK only from HK. Taken together, these results indicate that vascular leakage induction by staphopains is a mechanism of septic shock induction in severe S. aureus infection that provides an assay for determining the effectiveness of compounds to modulate vascular leakage.
Vascular Leakage Assay,
Animals can be evaluated for vascular leakage using the following procedure, 100 pL of a 1% solution of Evans blue dye (Sigma Aldrich) in saline is injected into the tail vein. Thirty minutes later, mice are sacrificed and perfused with saline via the right ventricle to remove intravascular Evans blue. Lungs are excised and extracted in 1 mL of formamide at 55 °C overnight. Evans blue content is determined as ODea minus ODjoo of the fonnamide extract. INFLUENZA
During the years following World War I, it is estimated that more that 50 million people were killed by a world-wide influenza pandemic. Recently, the spread of highly pathogenic avian influenza A (H5N1) viruses from Asia also poses a threat of becoming another influenza

2016203254 18 May 2016 pandemic. If is thought that highly pathogenic (HP) influenza strains stimulate a stronger immune response than seasonal strains, causing severe vascular leakage and lung edema, and eventual death, A study of mouse immune cell responses following exposure to mouse-adapted influenza viruses that mimic either a seasonal flu or a HP flu strain (Aldridge J.R. et al., ( 2009). TNF/tNOS-producing dendritic cells are the necessary evil of lethal influenza virus infection, Proc Nail Acad Sci USA 106: 5306- 5311),
The compounds disclosed herein can be used as a single pharmaceutical therapy to prevent the severity of influenza by mediating the effects of vascular leak caused by viruses, and hence, allowing the body’s own immune system to affect greater resistance to these pathogens. The following assays can be used to determine the effect of the disclosed compounds to inhibit viral severity because of improved vascular integrity.
The disclosed assays can utilize inhibition of viral plaques, viral cytopathic effect (CPE), and viral hemagglutitin.
Proteolytic Sensitivity Assay
The disclosed compounds can be determined to bind to hemagglutinin and thereby destabilize the protein assembly. The following procedure can be used to determine the increase in destabilization and therefore the increased sensitivity of hemagglutinin to proteolytic attack caused by the disclosed compounds, At the fusion conformation, HA becomes more sensitive to protease digestion. This property can be used to verify if a fusion inhibitor interacts with HA (Luo G. et al. “Molecular mechanism underlying the action of a novel fusion inhibitor of influenza A virus.” J Virol (1997); 71(5):4062-70). Thus, the disclosed compounds, due to the control of vascular leakage, can be evaluated for their ability to indirectly effect HA digestion by enhancing the body’s immune response.
The purified trimer of hemagglutinin ectodomain is incubated with the compound to be tested at a concentration of 5 μΜ. The irimers are subjected to trypsin digestion at pH 7,0 and pH 5.0 with controls of untreated HA and HA treated with DMSO which is the solvent used to dissolve the test compound. For the pH 5.0 sample, the HA trimers are treated with a pH 5.0 buffer for 15 minutes and neutralized to pH 7.0. Trypsin (20 ng) is added to the sample in 10 gland the digestion allowed to proceed for 1 hour at 37 °C, The amount of HA present is assessed by a western blot gel electrophoresis using anti-HA (H3) antisera. Samples containing effective inhibitors will provide an increase in digestion of HA by trypsin.

In addition, combination therapies can provide a method for treating influenza by providing an antiviral medication together with a compound that prevents the severity of vascular leakage due to influenza viruses.
An antiviral compound, for example, oseltamivir, can be used for an in vivo evaluation of the disclosed combination therapy and to evaluate the effectiveness of the disclosed compounds. The drag combination is administered in a single dose to mice infected with the influenza A/NWS/ (HIN1) virus, In some instances, infection of the animals will include multiple passage of the virus through their lungs. One convenient protocol involves administering 20 mg/kg per day twice daily for 5 days beginning 4 hours prior to virus exposure. The animals are then challenged with different concentrations of virus, ranging 10-fold from 10'2 ¢105,75 cell culture 50 % infectious doses (CCID50) per mL). Four mice in each group are sacrificed on day 6 and their lungs removed, assigned a consolidation score ranging from 0 (normal) to 4 (maximal plum coloration), weighted, homogenized, the homogenates centrifuged at 2000 x g for 10 minutes, and varying 10-fold dilutions of the supemata assayed for vims titer in MDCK cells using CPE produced after a 96-bour incubation at 37 ”C as endpoint.
The serum taken from mice on day 6 is assayed for a·.-AG using single radial immunodiffusion kites. Eight additional mice in each group are continually observed daily for death for 21 days, and their arterial oxygen saturation (SaOj) values determined by pulse oximetery (Sidwell R. et al., (1992) Utilization of pulse oximetry for the study of the inhibitory effects of antiviral agents on influenza virus in mice. Antimicrob. Agents Chemother. 36,473476) on day 3, when SaO:, decline usually begins to occur, through day 11, when the values are seen to decline to the maximum degree of the animals otherwise die.
Vasogenic Edema adult male Sprague-Dawley rats purchased from Charles River, Germany and weighing 250-330 g were used for the experiment. Animals were housed at a standard temperature (22 ± PC) and in a light-controlled environment (lights on from 7 am to 8 pm) with ad libitum access to food and water.
Animals were grouped as follows:
Group A: 15 rats treated with Vehicle (2 mL/kg, t.i.d., s.c.) starting 1 hour after stroke onset Group B: 15 rats treated with AKB-9778-AS (15 mg/kg, t.i.d., s.c.) stalling 1 hour after stroke onset

2016203254 18 May 2016 tMCAO
Transient focal cerebral ischemia was produced by MCA occlusion in male SpragueDawley rats according to Koizumi with modifications (Koizumi et al, Jprt. J. Stroke 8:1-8,
1986), The rats were anesthetized with isoflurane in 70% N?O and 30% Cb; flow 300 mL/min. 2-3 min anesthesia induction with 5% isoflurane after which 1-2% isoflurane. The rectal temperature was maintained above 36.0 “C with a homeothermic blanket system. After a midlinc skin incision, the right common carotid artery (CCA) was exposed, and the external carotid artery (EGA) was ligated distal from the carotid bifurcation, A 0.25-mm diameter monofilament nylon thread, with tip blunted, was inserted 22-23 mm into the internal carotid artery (ICA) up to the origin of MCA. The wound was temporarily closed and the rats were allowed to recover. After 60 min of ischemia, the rats were re-anesthetized and MCA blood flow was restored by removal of the thread. The wounds were dosed, disinfected, and the animals were allowed to recover from anesthesia. The rats were carefully monitored for possible post-surgical complications after the tMCAO. The rats were fed with standard laboratory diet suspended in tap water.
D91 or vehicle was administered s.c. three times a day. Treatment was given 1,8, 16, 23, 32, 40 and 47 h after the onset of occlusion. Administration volume was 2 ml/kg and the vehicle is sterile saline. The body weight of each animal is measured daily.
MRJ at 24 and 48 hours: Absolute T2 and Spin Density for Vasogenic Edema and Infarct Volume
T2-MRI was performed at 24 and 48 hours post-ischemia in a horizontal 7T magnet with bore size 160 mm (Magnex Scientific Ltd., Oxford, UK) equipped with Magnex gradient set (max. gradient strength 400 mT/m, bore 100 mm) interfaced to a Varian DirectDrive console (Varian, Inc.. Palo Alio, CA) using a volume coil for transmission and surface phased array coil for receiving (Rapid Biomedical GmbH, Rimpar, Germany). Isoflurane -anesthetized (1% in 30/70 O2/N2) rats were fixed to a head holder and positioned in the magnet bore in a standard orientation relative to gradient coils. All MRI data were analyzed using ίη-house written Matlab software. Region of interest analysis was performed for ipsilateral hemisphere, lesion core and perifocal area. Values from contralateral hemisphere were used as a reference.
Tissue viability and vasogenic edema was determined using absolute T2 MRI, Multi-echo multi-slice sequence was used with following parameters; TR - 3 s, 6 different echo times (12,

24, 36, 48, 60, 72 ms) and 4 averages. Seventeen (17) coronal slices of thickness 1 mm were acquired using field-of-view 30x30 mm2 and 256x128 imaging matrix (zero-filled to 256x256).
In addition to absolute T2, spin density (amount of MR! visible protons, indicator of vasogenic edema) ratio of ipsi and contralateral ROFs was determined by extrapolating signal intensity at
TE~0 from multiple TE data (intercept of T2 fitting).
For the determination of infarct volume, the same acquired T2-weighted images were analyzed using in-house written Matlab based software for morphometric measurement. The infarct volume analysis was done by an observer blinded to the treatment groups.
Dav for Cytotoxic Edema
Cytotoxic edema (and its time course) was evaluated also at 24 and 48 hours as a control measure using diffusion MRI; the data for calculation of 1/3 of the trace of the diffusion tensor (which is an orientation independent measure of apparent water difftision) were acquired using a diffusion weighted Fast Spin-Echo sequence. Following parameters were used: TR *=* 1.5 s, ETL/TEeff:::4/26 ms, b-values 0, 1000 xl0-3 s/mm2, NT® 4, Imaging resolution, slice thickness and slice positioning were kept identical to absolute T2 MR! acquisition above. 5 slices were acquired and these were selected from absolute T2 images to best correspond to the center of lesion in antero-posterior direction.

At 48 hours post-operation, Gadolinium based contrast enhanced Tl-weighted MRI was applied to detect blood-brain barrier leakage. Femoral vein was cannuialed before the rat was placed into the MRI. Contrast agent was injected as an i.v. bolus (0.5 M Gd-DTPA 0,4 ml/kg i.v. bolus). Pre- and post-contrast agent Tl-weighted images were acquired with 15 min delay to allow proper uptake of the contrast agent, MRI was performed with conventional Tl-weighted gradient echo sequence with identical imaging resolution and slice positioning and with following parameters; TR ;; 0,16 s, TE = 5 ms, 70 degree flip and NT::: 32. Subtraction images (deltaR, post-Gd minus pre-Gd) were produced to highlight and quantify BBB leakage. Gd-based contrast agents affect the T2 relaxation, thus this MRI component was performed at the very end of the MRI session.
