Description:
TRYPTOPHAN HYDROXYLASE INHIBITORS FOR USE IN THE TREATMENT

OF LIVER DISEASES

FIELD OF THE INVENTION

The present invention is directed to the treatment or prevention of liver diseases such as non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and hepatocellular carcinoma, using compounds which are inhibitors of tryptophan hydroxylase 1 (TPH1), or prodrugs thereof.

BACKGROUND OF THE INVENTION

Liver diseases such as non-alcoholic fatty liver disease (NAFLD) is characterized by the presence of hepatic steatosis, with or without inflammation and fibrosis, in the absence of alcohol history. NAFLD includes non-alcoholic fatty liver (NAFL) and non-alcoholic steatohepatitis (NASH). NASH affects about 2 to 5 percent of Americans according to the National Heath Instistute. NASH can occur in people who drink little or no alcohol and is usually a silient disease with few or no symptoms. NASH can be characterized by having fat in the liver, which is not normal, as well as having inflammation and damage. Although some people with NASH may feel normal, NASH can become severe and lead to fibrosis and cirrhosis, where the liver is permanently damaged and scarred. Diseased or damaged liver tissue caused, for example, from NASH-related cirrhosis can eventually lead to hepatocellular carcinoma.

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter that modulates central and peripheral functions by acting on neurons, smooth muscle, and other cell types. 5-HT is involved in the control and modulation of multiple physiological and psychological processes. Dysregulation of the peripheral 5-HT signaling system has been reported to be involved in the etiology of several conditions such as inflammatory (e.g. Margolis, K. G. et al. Pharmacological Reduction of Mucosal but Not Neuronal Serotonin Opposes Inflammation In Mouse Intestine. Gut doi: 10.1136/gutjnl-2013-304901 (2013); Duerschmied, D. et al. Platelet Serotonin Promotes The Recruitment Of Neutrophils To Sites Of Acute Inflammation In Mice. Blood 121, 1008-15 (2013); Li, N. et al. Serotonin Activates Dendritic Cell Function In The Context Of Gut

Inflammation. The American Journal of Pathology 178, 662-71 (2011)), and liver diseases or disorders (e.g. Ebrahimkhani, M. R. et al. Stimulating Healthy Tissue Regeneration By Targeting The 5-HT2B Receptor In Chronic Liver Disease. Nature Medicine 17, 1668-73 (2011)). See also, Nocito, A. et al. Gastroenterology 2007, 133, pp 608-618; Watanabe, H. et al.

Two vertebrate isoforms of tryptophan hydrolase (TPH), namely TPHl and TPH2, have been identified. TPHl is primarily expressed in the pineal gland and non-neuronal tissues, such as enterochromaffin (EC) cells located in the gastrointestinal (GI) tract. TPH2 (the dominant form in the brain) is expressed exclusively in neuronal cells, such as dorsal raphe or myenteric plexus cells. The peripheral and central systems involved in 5-HT biosynthesis are isolated, with 5-HT being unable to cross the blood-brain barrier. Therefore, the pharmacological effects of 5- HT can be modulated by agents affecting TPH in the periphery, mainly TPHl in the gut.

Increased 5-HT has been proposed to impact the pathophysiology of the liver through multiple mechanisms. For example, accumulation of lipids can sensitize the liver to

pathophysiology associated with NASH; hepatic oxidation of 5-HT can generate lipid peroxide and ROS leading to mitochondrial dysfunction; and pro-fibrotic and mitogenic activity mediated through 5-HT receptor binding and TGFP signaling leads to fibrosis.

There is a need for new therapies to treat liver diseases such as NAFLD, NASH, and hepatocellular carcinoma. The methods described herein employing TPHl inhibiors are intended to address this need.

It is appreciated that certain features of the invention, which are, for clarity, described in the context of separate embodiments, can also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, can also be provided separately or in any suitable subcombination. The term "substituted" means that an atom or group of atoms formally replaces hydrogen as a "substituent" attached to another group. The hydrogen atom is formally removed and replaced by a substituent. A single divalent substituent, e.g., oxo, can replace two hydrogen atoms. The term "optionally substituted" means unsubstituted or substituted. The substituents are independently selected, and substitution may be at any chemically accessible position. It is to be understood that substitution at a given atom is limited by valency. Throughout the definitions, the term "Ci-j" indicates a range which includes the endpoints, wherein i and j are integers and indicate the number of carbons. Examples include C1-4, Ci-6, and the like.

The term "n- member ed" where n is an integer typically describes the number of ring- forming atoms in a moiety where the number of ring-forming atoms is n. For example, piper idinyl is an example of a 6-membered heterocycloalkyl ring, pyrazolyl is an example of a 5- membered heteroaryl ring, pyridyl is an example of a 6-membered heteroaryl ring, and 1, 2, 3, 4- tetrahydro -naphthalene is an example of a 10-membered cycloalkyl group.

At various places in the present specification various aryl, heteroaryl, cycloalkyl, and heterocycloalkyl rings are described. Unless otherwise specified, these rings can be attached to the rest of the molecule at any ring member as permitted by valency. For example, the term "a pyridine ring" or "pyridinyl" may refer to a pyridin-2-yl, pyridin-3-yl, or pyridin-4-yl ring.

For compounds of the invention in which a variable appears more than once, each variable can be a different moiety independently selected from the group defining the variable. For example, where a structure is described having two R groups that are simultaneously present on the same compound, the two R groups can represent different moieties independently selected from the group defined for R.

Step 1: To a solution of (R)-l-(2-bromo-4-chlorophenyl)-2,2,2-trifluoroethanol (Intermediate 43, see U.S. Pub. No. 2015/0080393 paragraph [0463]) (400 mg, 1.4 mmol) in dioxane (25 mL) was added 4,6-dichloropyrimidin-2-amine (1.1 g, 7 mmol) and CS2CO3 (1.3 g, 4 mmol). The mixture was heated for 24 h at 80 °C. The reaction was then cooled to RT and filtered. The solvent was removed in vacuo, then CH2CI2 and heptane was added. The solvent volume was reduced until a solid precipitated out. The solid was filtered and the procedure repeated several times to provide (R)-4-(l-(2-bromo-4-chlorophenyl)-2,2,2-trifluoroethoxy)-6-c hloropyrimidin-2-amine as a white solid.

The reaction was then cooled to RT and filtered. Purification by normal phase silica gel column (EtO Ac/heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-l-(2-bromo-4- chlorophenyl)-2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diaz aspiro[4.5]decane-2,3-dicarboxylate as a white solid.

Step 3: To a solution of (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-l-(2-bromo-4-chlorophenyl)- 2,2,2-trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]dec ane-2,3-dicarboxylate (100 mg, 0.13 mmol) in 10: 1 dioxane:water (5 mL) was phenyl boronic acid (33 mg, 0.27 mmol), KHCO3 (27 mg, 0.3 mmol), and PdC^dppfj-CEbCb. (6 mg, 0.007 mmol). The reaction was heated to 100 °C for 15 h, cooled to RT, and concentrated in vacuo. The residue was diluted with water, and extracted with EtO Ac. The combined organic layers were dried over Na 2 S04, filtered, and concentrated in vacuo. Purification by normal phase silica gel column (EtO Ac/heptane) provided (S)-2-benzyl 3-ethyl 8-(2-amino-6-((R)-l-(5-chloro-[l,r-biphenyl]-2-yl)-2,2,2- trifluoroethoxy)pyrimidin-4-yl)-2,8-diazaspiro[4.5]decane-2, 3-dicarboxylate as an off-white solid.

Example A. Murine Model of NASH C57bl6 Mice on a Methionine-Choline Deficient (MCD) Diet

This study is designed to study the effect of the compounds of the present disclosure on a murine model of NASH C57bl6 mice on a MCD diet. An oral dose of the Compound 63 i (also known as the compound of Example 63 i) at 200 mg/kg elicited a positive effect on plasma and liver lipids as well as liver function enzymes in a murine model of NASH. The NASH model was induced by placing C57bL6 mice on a MCD diet which impairs VLDL assembly resulting in disruption of hepatic triglyceride secretion and subsequent fat accumulation within the liver (Rizki G, et al., J Lipid Res. 2006;2280-2290). MCD-fed mice were orally administered 200 mg/kg Compound 63 i once daily for 4 weeks. Treatment with Compound 63 i significantly reversed the effects of MCD feeding on serum lipids and liver triglycerides, bringing

concentrations back toward those observed in untreated, chow-fed control mice. Compound 63 i also significantly decreased alanine aminotransferase (ALT) and aspartate aminotransferase

(AST) serum concentrations, suggesting that TPHl inhibition improved liver function compared to MCD-fed vehicle controls.

The chemicals used in this study were: triton X-100 (Sigma - Cat #X100), cholesterol assay kit (Wako Diagnostics - Cat #439-17501), triglyceride assay kit (Wako Diagnostics - Cat #461-08992 and Cat #461-09092), triglyceride standard (Wako Diagnostics - Cat #464-01601), alanine aminotransferase (ALT) assay (Cayman Chemical - Cat #700260), aspartate

aminotransferase (AST) assay (Sigma - Cat #MAK055), phosphate buffered saline (Sigma - Cat#P3813), sucrose (Sigma - Cat #S7903), gum Arabic (Sigma - Cat #G9752), oil red O in 0.5% propylene glycol (Polyscientific - Cat #sl 848), and OCT Compound (Tissue Tek - Cat #4583).

The control diet was an irradiated rodent diet 18% protein (Envigo #2918). The challenge diet was a MCD diet (Envigo #TD90262).

Oral doses of 200 mg/kg Compound 63 i (as a free base) were prepared in a 0.5% methyl cellulose vehicle prepared in water. Vehicle was added to the compound on the day of dosing and the mixture was briefly sonnicated then mixed for -20 minutes until a homogenous suspension was achieved. Doses were administered by oral gavage at 10 mL/kg of body weight.

The animals used for the study are described below.

Male mice (n=10 per group) arrived at the facility at 28-30 g and were housed 5 per cage on corncob bedding. The animals were acclimated to handling for 7-10 days prior to the start of the study. Mice were administered a single oral dose of vehicle (0.5% methyl cellulose in water) or 200 mg/kg Compound 63 i once daily for 4 weeks prior to the start of the dark cycle. During the dosing period, vehicle and Compound 63i-treated mice were fed either a normal chow diet or a MCD diet. On week 4, blood samples were collected from fed mice for measurement of cholesterol, triglycerides, alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in isolated serum. Following whole body perfusion in situ with 10 rriL of PBS, the central lobe of the liver was removed and fixed in 4% paraformaldehyde for histological measurements. An additional liver sample (100 mg) was snap frozen in liquid nitrogen for measurement of liver triglycerides. Blood Collection

On week 4, mice were anesthetized with isofluorane administered 2% in oxygen continuous via inhalation. Whole blood samples (800 μΐ.) were obtained via cardiac puncture and allowed to clot at room temperature for 30 minutes. Serum was isolated by centrifugation at 7000 rpm for 20 minutes and stored at -80 °C for measurement of cholesterol, triglycerides, alanine aminotransferase and aspartate aminotransferase.

Serum Cholesterol

Cholesterol concentrations were measured in serum using a colorimetric assay (Wako Diagnostics) according to kit instructions. Briefly, 3 μΐ. of each standard or sample was added to the wells of a 96-well clear bottom plate. Standards were prepared by diluting a 200 mg/dL stock solution in water. The reaction was accomplished by adding 300 μΐ. of the assay reagent and incubating at 37 °C for 5 minutes. The absorbance was read on a spectrophotometer at 600 nm. Serum Triglycerides

Triglyceride concentrations were measured in serum using a colorimetric assay (Wako Diagnostics) according to kit instructions. Briefly, 4 μΐ. of each standard or sample was added to the wells of a 96-well clear bottom plate. Standards were prepared by diluting a 98 mg/dL stock solution in water. The reaction was accomplished by adding 180 μL of the first assay reagent and incubating at 37 °C for 5 minutes. The reaction continued by adding 60 μL of the second assay reagent and incubating at 37 °C for an additional 5 minutes. The absorbance was read on a spectrophotometer at 600 nm.

Serum Alanine Aminotransferase

Serum was isolated as described in above and liver function was assessed by measuring alanine aminotransferase (ALT) concentrations in serum using a colorimetric assay according to kit instructions. Briefly, 20 μL of serum samples or standards were added to a clear bottom 96- well plate with 150 μL of substrate and 20 μL co-factor. After the samples were incubated at 37 °C for 15 minutes, the reaction was initiated by adding 20 μL of an ALT initiator. The absorbance was immediately read on a spectrophotometer at 340 nm every minute for 5 minutes. Change in absorbance (ΔΑ340/ min) was determined by calculating the change in absorbance at 2 points over the linear portion of the curve (a), and ALT activity (U/mL) was calculated using the equation in (b):

(a) (A340 Time 1 - A340 Time 2) b) (ΔΑ340/ min x 0.21 mL)

Time 2 (min) - Time 1 (min) (4.11mM "1 * 0.02mL)

Serum Aspartate Aminotransferase

Serum was isolated as described in above and liver function was assessed by measuring aspartate aminotransferase (AST) concentrations in serum using a colorimetric assay according to kit instructions. Briefly, 5 μL of serum samples or standards were added to a clear bottom 96- well plate with 45μL of AST assay buffer. Standards were prepared by diluting a 1 mM glutamate stock in AST assay buffer. The reaction was accomplished by adding 100 μL of a reaction mix containing 80 μL of buffer + 2μL enzyme + 8μL developer + 10μL substrate and incubating at 37 °C for 3 minutes. The initial absorbance [AST]initiai was read on a

spectrophotometer at 450 nm. Sample incubation continued at 37 °C and absorbance was read every 5 minutes at 450nm. The reaction was complete [AST]fi ra i when the most active sample had a value greater than the highest standard. For each sample, the concentration of glutamate generated (nmoL), or A[AST], was determined as:

[AST]final - [AST]initial

AST activity (nmoL/min/mL), or the concentration of enzyme that will generate 1 μηκΛ of glutamate per minute at 37 °C was calculated as: A[AST] x Sample Dilution Factor

(Reaction Time) x V

where,

Reaction Time (min) = Tfmai - 1 initial

V (rriL) = Volume added to well

Liver Collection

Following blood collection, mice were euthanized by exsanguination under anesthesia according to regulations in the Guide for the Care and Use of Laboratory Animals and whole body perfusion was accomplished with 10 mL of PBS. A liver sample was snap frozen in liquid N 2 and stored at -80 °C until processed for triglyceride measurements. The central lobe of the liver was removed and fixed in 4% paraformaldehyde for 24 hours prior to processing for histological measurements. Liver Triglycerides

Frozen liver samples (50 mg) were transferred to tubes containing 1 mm high impact zirconium beads (Benchmark Scientific) and 500 μL of 5% Triton X-100 in phosphate buffered saline. The samples were homogenized for 2 minutes on a Bead Bug microtube homogenator (Benchmark Scientific) until completely solubilized and centrifuged at 13,000 rpm for 5 minutes at 4 °C. Prior to assay, the samples were further diluted 1 :4 in 5% Triton X-100. Liver triglyceride concentrations were measured using a colorimetric assay (Wako Diagnostics) according to kit instructions. Briefly, 4 μL of sample or standards were added to the wells of a clear bottom 96-well plate. Standards were prepared by diluting a 98 mg/dL stock solution in 5% Triton X-100. The reaction was accomplished by adding 180 μL of the first assay reagent and incubating at 37 °C for 5 minutes. The reaction continued by adding 60 μL of the second assay reagent and incubating at 37 °C for an additional 5 minutes. The absorbance was read on a spectrophotometer at 600 nm.

Hepatic Lipid Deposition

A randomly chosen subset of formalin fixed liver tissue samples was infiltrated with a

30% sucrose + 1% gum arabic solution at 4 °C for 24-48 hours prior to being embedded in OCT compound within a cryostat chamber at -18 °C. Liver samples were cryo-sectioned at 10 μΜ and stained with Oil red O in 0.5% propylene glycol for evaluation of lipid deposition. Statistical Analysis

Analysis of variance (ANOVA) was used to test for significant differences between groups. Post-hoc Bonferroni multiple comparison test analysis was used to determine significant differences among means. All statistical analysis was accomplished using Graph Pad Prism 5 software.

The results are summarized in below. Table Al. Effect of Compound 63i on Serum Cholesterol and Triglycerides in Male C57bL6 Mice Fed a MCD Diet for 4 weeks

Example B. Murine Model of NASH ApoE Knockout Mice on a High Fat Diet

This study is designed to study the effect of the compounds of the present disclosure on a murine model of NASH ApoE knockout mice on a high fat diet. An oral dose of Compound 63 i (also referred to as the compound of Example 63 i) at 200 mg/kg elicited a positive effect on liver pathophysiology in a murine model of NASH. The NASH model was induced by placing ApoE knockout mice on a high fat diet. High fat fed mice were orally administered 200 mg/kg Compound 63 i once daily for 8 weeks. Treatment with Compound 63 i significantly reversed the effects of high fat feeding on hepatic lipid deposits and liver architecture compared to high fat fed vehicle controls. A significant decrease in serum serotonin with no effect on serum cholesterol, triglycerides or glucose was observed in mice treated with Compound 63 i.

The control diet was an irradiated rodent diet 18% protein (Envigo #2918). The challenge diet was a high fat diet with 1.25% cholesterol and 21% fat from coconut oil (Research Diets #D15100301).

The test compound was the compound of Example 63 i (also referred to as Compound

63 i). It is used as a free base. Oral doses of 200 mg/kg Compound 63i were prepared in a 0.5% methyl cellulose vehicle prepared in water. Vehicle was added to the compound on the day of dosing and the mixture was briefly sonnicated then mixed for -20 minutes until a homogenous suspension was achieved. Doses were administered by oral gavage at 10 mL/kg of body weight. The animals used in the study are described in the table below.

Male mice (n=10 per group) arrived at the facility at 28-3 Og and were housed 4 per cage on corncob bedding. The animals were acclimated to handling for 7-10 days prior to the start of the study. Mice were administered a single oral dose of vehicle (0.5% methyl cellulose in water) or 200 mg/kg Compound 63 i once daily for 8 weeks prior to the start of the dark cycle. During the dosing period, vehicle and Compound 63 i treated mice were fed either a normal chow diet or a high fat diet containing 1.25% cholesterol and 21% fat from coconut oil. On week 8, blood samples were collected from fed mice for measurement of serotonin, cholesterol, triglycerides and glucose in isolated serum. Following whole body perfusion in situ with 10 mL of PBS, the central lobe of the liver was removed and fixed in 4% paraformaldehyde for histological measurements.

Blood Collection

On week 8, mice were anesthetized with isofluorane administered 2% in oxygen continuous via inhalation. Whole blood samples (800 μΐ.) were obtained via cardiac puncture and allowed to clot at room temperature for 30 minutes. Serum was isolated by centrifugation at 7000 rpm for 20 minutes and stored at -80 °C for measurement of serotonin, cholesterol, triglycerides and glucose.

Serum Serotonin Measurement

Serum samples were extracted in a trichloroacetic acid (TCA) homogenization buffer. Briefly, 100 μΙ_, of TCA buffer was added to 50 μΙ_, of serum in a 1.5 mL micro fuge tube. The sample was vortexed in the buffer and centrifuged at 13,000 rpm for 30 minutes at 4 °C. The supernate was carefully removed and transferred to a glass tube for measurement of serotonin with fluorometric detection using the conditions described above.

High Performance Liquid Chromatography (HPLC) Conditions

HPLC homogenization buffer was prepared as follows:

HPLC measurements were made using a Perkin Elmer Flexar HPLC system equipped with a fluorescent detector and a Brownlee validated aqueous CI 8 column (3 μιτι, 50 x 2.1 mm; Perkin Elmer). Mobile phase used was 100 mM sodium acetate, pH 3.5. Detection was achieved at an excitation wavelength of 280 nm and an emission wavelength of 330 nm.

Serum Cholesterol

Cholesterol concentrations were measured in serum using a colorimetric assay (Wako Diagnostics) according to kit instructions. Briefly, 3 μΕ of each standard or sample was added to the wells of a 96-well clear bottom plate. Standards were prepared by diluting a 200 mg/dL stock solution in water. The reaction was accomplished by adding 300 μΕ of the assay reagent and incubating at 37 °C for 5 minutes. The absorbance was read on a spectrophotometer at 600 nm.

Serum Triglycerides

Triglyceride concentrations were measured in serum using a colorimetric assay (Wako Diagnostics) according to kit instructions. Briefly, 4 μΕ of each standard or sample was added to the wells of a 96-well clear bottom plate. Standards were prepared by diluting a 98 mg/dL stock solution in water. The reaction was accomplished by adding 180 μΕ of the first assay reagent and incubating at 37 °C for 5 minutes. The reaction continued by adding 60 μΕ of the second assay reagent and incubating at 37 °C for an additional 5 minutes. The absorbance was read on a spectrophotometer at 600 nm. Serum Glucose

Glucose oxidase concentrations were measured in serum using a colorimetric assay (Cayman) according to kit instructions. Briefly, 15 μΐ. of each standard or sample was added to the wells of a 96- well clear bottom plate each containing 85 μΐ. of an assay buffer provided by the vendor. Standards were prepared by diluting a 100 mg/dL stock solution in assay buffer. The reaction was accomplished by adding 100 μΐ. of enzyme reagent and incubating at 37 °C for 10 minutes. The absorbance was read on a spectrophotometer at 500-520 nm. Liver Collection

Following blood collection, mice were euthanized by exsanguination under anesthesia according to regulations in the Guide for the Care and Use of Laboratory Animals and whole body perfusion was accomplished with 10 mL of PBS. The central lobe of the liver was removed and fixed in 4% paraformaldehyde for 24 hours prior to processing for histological measurements.

Histological Analysis

A randomly chosen subset of formalin fixed liver tissue samples was infiltrated with a 30% sucrose + 1% gum arabic solution at 4 °C for 24-48 hours prior to being embedded in OCT compound within a cryostat chamber at -18 °C. Liver samples were cryo-sectioned at 10 μηι and stained with Oil red O in 0.5% propylene glycol for evaluation of lipid deposition.

A portion of the liver was processed, embedded in paraffin and sectioned at 5 μηι for staining of Mallory Bodies and structural changes with chromotrophe-analine blue. Statistical Analysis

Analysis of variance (ANOVA) was used to test for significant differences between groups. Post-hoc Bonferroni multiple comparison test analysis was used to determine significant differences among means. All statistical analysis was accomplished using Graph Pad Prism 5 software.

The results are summarized below. Table Bl. Effect of Compound 63i on Serum Serotonin in Male ApoE Knockout Mice Fed Either a High Fat or Chow Diet for 8 Weeks

Serum was isolated from blood samples collected from ApoE Knockout mice following weeks of oral dosing with 200 mg/kg Compound 63 i while fed either a high fat or chow diet. Serotonin (5-HT) was measured by high performance liquid chromatography. A significant decrease in serum 5-HT was observed in Compound 63i treated mice on both the chow and fat diet. ****p<0.0001 and††††p<0.0001 significance relative to high fat or chow fed vehicle controls, respectively. Table B2. Effect of Compound 63 i on Serum Cholesterol, Triglycerides and Glucose in Male ApoE Knockout Mice Fed Either a High Fat or Chow Diet for 8 Weeks

Serum was isolated from blood samples collected from ApoE knockout mice following 8 weeks of oral dosing with 200 mg/kg Compound 63 i while fed either a high fat or chow diet. Cholesterol, triglyceride and glucose concentrations were measured by a colorimetric assay. No significant changes in cholesterol, triglycerides, or glucose were observed regardless of diet.

Lipid deposition was evaluated in liver tissue collected from high fat fed ApoE Knockout mice following oral administration of 200 mg/kg Compound 63 i for 8 weeks. Lipid deposits were indicated by dark red Oil red O staining which demonstrates a qualitative decrease in lipid deposition in fat fed mice treated with Compound 63 i as compared to vehicle treated mice.

Improvement in liver architecture was observed in liver tissue collected from high fat fed ApoE Knockout mice following oral administration of 200 mg/kg Compound 63i for 8 weeks. An increase in appearance of vacuoles around major vessels and a breakdown of structural integrity was demonstrated by chromatrophe 2B-analine blue staining in mice treated with vehicle compared to those treated with 200 mg/kg Compound 63 i.

Example C. Murine Model of NASH LDLr Knockout Mice on a Methionine Choline Deficient (MCD) or High Fat Diet

This study is designed to study the effect of the compounds of the present disclosure on a murine model of NASH LDLr knockout mice on a MCD or high fat diet. An oral dose of Compound 63 i (also referred to as the compound of Example 63 i) at 200 mg/kg elicited a positive effect on liver pathophysiology in two murine models of NASH. In the first, the NASH model was induced by placing LDLr knockout mice on a MCD diet which impairs VLDL assembly resulting in disruption of hepatic triglyceride secretion and subsequent fat

accumulation within the liver (Rizki G., et al., J Lipid Res. 2006;2280-2290). In the second, the NASH model was induced by placing LDLr knockout mice on a high fat diet containing 1.25% cholesterol and 21% fat from coconut oil. MCD or fat fed mice were orally administered 200 mg/kg Compound 63 i once daily for 3 and 8 weeks, respectively. Treatment with Compound 63 i significantly reversed the effects of high fat feeding on hepatic lipid deposits and liver architecture compared to high fat fed vehicle controls. A significant decrease in serum serotonin with no effect on serum cholesterol, triglycerides or glucose was observed in mice treated with Compound 63 i.

The control diet was an irradiated rodent diet 18% protein (Envigo #2918). The challenge diets were a MCD diet (Envigo #TD90262) and high fat diet with 1.25% cholesterol and 21% fat from coconut oil (Research Diets #D15100301).

Oral doses of 200 mg/kg Compound 63 i (free base) were prepared in a 0.5% methyl cellulose vehicle prepared in water. Vehicle was added to the compound on the day of dosing and the mixture was briefly sonnicated then mixed for -20 minutes until a homogenous suspension was achieved. Doses were administered by oral gavage at 10 mL/kg of body weight.

The animals used in the study are described in the table below.

Male mice (n=10 per group) arrived at the facility at 28-30 g and were housed 4 per cage on corncob bedding. The animals were acclimated to handling for 7-10 days prior to the start of the study. Mice were fed either a MCD diet or a high fat diet containing 1.25% cholesterol and 21% fat from coconut oil for 3 and 8 weeks, respectively. While on diet, mice were administered a single oral dose of vehicle (0.5% methyl cellulose in water) or 200 mg/kg Compound 63 i once daily prior to the start of the dark cycle. At the end of the dosing period, blood samples were collected from fed mice for in-house measurement of serum serotonin and measurement of serum cholesterol, triglycerides, glucose, alanine aminotransferase (ALT) or aspartate aminotransferase (AST) by an outside contractor. Following whole body perfusion in situ with 10 rriL of PBS, the central lobe of the liver was removed and fixed in 4% paraformaldehyde for histological measurements. Gut mucosa samples were collected for measurement of serotonin by high performance liquid chromatography. Blood Collection

At the end of the dosing period, mice were anesthetized with isofluorane administered 2% in oxygen continuous via inhalation. Whole blood samples (1 mL) were obtained via cardiac puncture and allowed to clot at room temperature for 30 minutes. Serum was isolated by centrifugation at 6000 rpm for 20 minutes and a 50 μΐ. sample was stored at -80° C for measurement of serotonin. The remaining serum was shipped to Charles River (Shrewsbury,

Mass) for measurements of serum cholesterol, triglycerides, glucose, and liver function enzymes (ALT and AST).

Serum Serotonin Measurement

Serum samples were extracted in a trichloroacetic acid (TCA) homogenization buffer.

Briefly, 100 μL of TCA buffer was added to 50 μL of serum in a 1.5 mL micro fuge tube. The sample was vortexed in the buffer and centrifuged at 13,000 rpm for 30 minutes at 4 °C. The supernate was carefully removed and transferred to a glass tube for measurement of serotonin with fluorometric detection using the conditions described above. High Performance Liquid Chromatography (HPLC) Conditions

HPLC homogenization buffer were prepared according to the table below.

HPLC measurements were made using a Perkin Elmer Flexar HPLC system equipped with a fluorescent detector and a Brownlee validated aqueous CI 8 column (3 μπι, 50 x 2.1 mm; Perkin Elmer). Mobile phase used was 100 mM sodium acetate, pH 3.5. Detection was achieved at an excitation wavelength of 280 nm and an emission wavelength of 330 nm. Gut Mucosa Collection

Following blood collection, mice were euthanized by exsanguination under anesthesia according to regulations in the Guide for the Care and Use of Laboratory Animals and whole body perfusion was accomplished with 10 mL PBS. The stomach was located and

approximately 6-8 cm of intestine beginning at the pyloric sphincter (duodenum) and the adjacent 6-8cm (jejunum) were removed. The duodenum was discarded and the intestinal contents of the jejunum were flushed out using a dosing needle attached to a 10 cc syringe filled with PBS. A longitudinal cut was then made along one side of the segment which was opened flat on a glass microscope slide. The gut mucosa was scraped away from the luminal surface using a second microscope slide and collected in 2mL flat bottom microfuge tubes.

Approximately 50mg of each sample was transferred to a second 2mL flat bottom microfuge tube for extraction and serotonin measurement.

Gut Mucosal Serotonin Measurement

Gut mucosa samples were extracted in a trichloroacetic acid (TCA) homogenization buffer. Briefly, 300 μΕ of TCA buffer was added to 50-75 mg of tissue in a 2 mL flat bottom microfuge tube. The tissue was homogenized in the buffer and centrifuged at 13,000 rpm for 30 minutes at 4 °C. The supernate was carefully removed and transferred to a glass tube for measurement of serotonin with fluorometric detection using the conditions described above. After completely removing any residual supernate from the tissue pellets, 1200 μΐ. of 5% sodium dodecyl sulfate buffer (SDS) prepared in 0.1 N sodium hydroxide (NaOH) was added to each microfuge tube and the samples were solubilized in a 37 °C oven overnight prior to protein measurement.

Gut Mucosal Protein

Gut mucosal protein concentration was measured in digested mucosa tissue pellets using a colorimetric assay (Pierce BCA Protein, Fisher) according to kit instructions. Briefly, 5 μΐ. of sample was diluted in a clear bottom 96-well plate with 20 μΐ. of 5% SDS buffer prepared in 0. IN NaOH. Standards were prepared by diluting a 2 mg/mL stock albumen solution in 5% SDS buffer. The reaction was accomplished by adding 200 μΐ. of the BCA protein reagent and incubating at 37 °C for 30 minutes. The absorbance was read on a spectrophotometer at 562 nm.

Liver Collection

Following blood collection, mice were euthanized by exsanguination under anesthesia according to regulations in the Guide for the Care and Use of Laboratory Animals and whole body perfusion was accomplished with 10 mL of PBS. The central lobe of the liver was removed and fixed in 4% paraformaldehyde for 24 hours prior to processing for histological measurements.
