Description
DIACYLGLYCEROL ACYLTRANSFERASE INHIBITORS
The invention relates to inhibitors of diacylglycerol acyltransferase. The inhibitors are useful for the treatment of diseases such as obesity, type II diabetes mellitus, dyslipidemia and metabolic syndrome.
Triglycerides or triacylglycerols are the major form of energy storage in eukaryotic organisms. In mammals, these compounds are primarily synthesized in three tissues: the small intestine, liver, and adipocytes. Triglycerides or triacylglycerols support the major functions of dietary fat absorption, packaging of newly synthesized fatty acids and storage in fat tissue (see Subauste and Burant, Current Drug Targets - Immune, Endocrine & Metabolic Disorders (2003) 3, 263-270).
Diacylglycerol 0-acyltransferase, also known as diglyceride acyltransferase or DGAT, is a key enzyme in triglyceride synthesis. DGAT catalyzes the final and rate-limiting step in triacylglycerol synthesis from 1,2-diacylglycerol (DAG) and long chain fatty acyl CoA
as substrates. Thus, DGAT plays an essential role in the metabolism of cellular diacylglycerol and is critically important for triglyceride production and energy storage homeostasis (see Mayorek et al, European Journal of Biochemistry (1989) 182, 395-400).
DGAT has a specificity for sn-1,2 diacylglycerols and will accept a wide variety of fatty acyl chain lengths (see Farese et al, Current Opinions in Lipidology (2000) 11, 229-234).
DGAT activity levels increase in fat cells as they differentiate in vitro and recent evidence suggests that DGAT may be regulated in adipose tissue post-transcriptionally (see Coleman et al, Journal of Molecular Biology (1978) 253, 7256-7261 and Yu et al, Journal of Molecular Biology (2002) 277, 50876-50884). DGAT activity is primarily expressed in the endoplasmic reticulum (see Colman, Methods in Enzymology (1992) 209, 98-104). In hepatocytes, DGAT activity has been shown to be expressed on both the

DGAT activity is primarily expressed in the endoplasmic reticulum (see Colman, Methods in Enzymology (1992) 209, 98-104). In hepatocytes, DGAT activity has been shown to be expressed on both the
-2-cytosolic and luminal surfaces of the endoplasmic reticular membrane (see Owen et al, Biochemical Journal (1997) 323 (pt 1), 17-21 and Waterman et al, Journal of Lipid Research (2002) 43, 1555-156). In the liver, the regulation of triglyceride synthesis and partitioning, between retention as cytosolic droplets and secretion, is of primary importance in determining the rate of VLDL production (see Shelness and Sellers, Current Opinions in Lipidology (2001) 12, 151-157 and Owen et al, Biochemical Journal (1997) 323 (pt 1), 17-21).
Two forms of DGAT have been cloned and are designated DGATl and DGAT2 (see lo Cases et al, Proceedings of the National Academy of Science, USA (1998) 95, 13023, Lardizabal et al, Journal of Biological Chemistry (2001) 276, 38862-38869 and Cases et al, Journal of Biological Chemistry (2001) 276, 38870-38876).
Although both enzymes utilize the same substrates, there is no homology between DGATl and DGAT2.
Both enzymes are widely expressed however some differences do exist in the relative abundance of expression in various tissues.
The gene encoding mouse DGATl has been used to create DGAT knock-out. These mice, although unable to express a functional DGAT enzyme (Dgat-/- mice), are viable and continue to synthesize triglycerides (see Smith et al, Nature Genetics (2000) 25, 87-90). This would suggest that multiple catalytic mechanisms contribute to triglyceride synthesis, such as DGAT2. An alternative pathway has also been shown to form triglycerides from two diacylglycerols by the action of diacylglycerol transacylase (see Lehner and Kuksis, Progress in Lipid Research (1996) 35, 169-210).
Dgat-/- mice are resistant to diet-induced obesity and remain lean. When fed a high fat diet, Dgat-/- mice maintain weights comparable to mice fed a diet with regular fat content. Dgat-/- mice have lower tissue triglyceride levels. The resistance to weight gain seen in the knockout mice, which have a slightly higher food intake, is due to an increased energy expenditure and increased sensitivity to insulin and leptin (see Smith et 3o al, Nature Genetics (2000) 25, 87-90, Chen and Farese, Trends in Cardiovascular Medicine (2000) 10, 188-192, Chen and Farese, Current Opinions in Clinical Nutrition and Metabolic Care (2002) 5, 359-363 and Chen et al, Journal of Clinical Investigation (2002) 109, 1049-1055). Dgat-/- mice have reduced rates of triglyceride absorption, improved triglyceride metabolism, and improved glucose metabolism, with lower glucose and insulin levels following a glucose load, in comparison to wild-type mice (see
Two forms of DGAT have been cloned and are designated DGATl and DGAT2 (see lo Cases et al, Proceedings of the National Academy of Science, USA (1998) 95, 13023, Lardizabal et al, Journal of Biological Chemistry (2001) 276, 38862-38869 and Cases et al, Journal of Biological Chemistry (2001) 276, 38870-38876).
Although both enzymes utilize the same substrates, there is no homology between DGATl and DGAT2.
Both enzymes are widely expressed however some differences do exist in the relative abundance of expression in various tissues.
The gene encoding mouse DGATl has been used to create DGAT knock-out. These mice, although unable to express a functional DGAT enzyme (Dgat-/- mice), are viable and continue to synthesize triglycerides (see Smith et al, Nature Genetics (2000) 25, 87-90).

Disorders or imbalances in triglyceride metabolism, both absorption as well as de novo synthesis, have been implicated in the pathogenesis of a variety of disease risks. These include obesity, insulin resistance syndrome, type II diabetes, dyslipidemia, metabolic syndrome (syndrome X) and coronary heart disease (see Kahn, Nature Genetics (2000) 25, 6-7, Yanovski and Yanovski, New England Journal of Medicine (2002) 346, 602, Lewis et al, Endocrine Reviews (2002) 23, 201, Brazil, Nature Reviews Drug lo Discovery (2002) 1, 408, Malloy and Kane, Advances in Internal Medicine (2001) 47, 111, Subauste and Burant, Current Drug Targets - Immune, Endocrine & Metabolic Disorders (2003) 3, 263-270 and Yu and Ginsberg, Annals of Medicine (2004) 36, 261). Compounds that can decrease the synthesis of triglycerides from diacylglycerol by inhibiting or lowering the activity of the DGAT enzyme would be of value as therapeutic agents for the treatment diseases associated with abnormal metabolism of triglycerides.

The nitrogen that links spacer Q and the tert-butyloxycarbonyl group can be part of the ring (e.g. compound v) or outside of the ring (e.g. compound vii). The tert-butyloxycarbonyl group in the coupling product can be cleaved under acidic condition to generate the corresponding amine xviii.
In addition, heterocyclic carboxylic acid xvi can also be coupled with amine ix, xi and xiii under the same amide formation conditions. The esters of the amide coupling product can further be hydrolyzed to generate the corresponding carboxylic acids.

-30-The key intermediate xviii in Scheme 3 can be functionalized to form various amides, carbamates and ureas. As shown in Scheme 4, compound xviii can be treated with acyl chloride or carboxylic acid to form amide xix (R' can be cyclic or acyclic alkyl group).
For the formation of urea xx, compound xviii can be treated with isocyanate or alkylaminocarbonyl chloride. Finally, the reaction of xviii with alkoxycarbonyl chloride will generate carbamate xxi.
To prepare amides with terminal carboxylic acids, xviii can be treated with anhydride xxiii (E can be cyclic or acyclic alkyl group) to form carboxylic acid xxiv.
In case when xxiii is not readily available, the direct coupling of xviii with dicarboxylic acid xxii using coupling reagents can also lead to xxiv.
Alternatively, the dicarboxylic acid in xxii can be transformed to a mono-ester mono-carboxylic acid which can be coupled with xviii, and the cleavage of the resulting ester will generate compound xxiv.
For compound xxii, when spacer E is cyclic, the dicarboxylic acid can be in cis or trans-conformation. For cases where spacer E has stereogenic centers, single enantiomers of compound xxiv can be prepared through chiral separation.

LCMS calcd for C26H25F6N505 (m/e) 601.5, obsd 601.9 (M+H).
To a flask containing (S)-3-(5-{[2-(2-trifluoromethoxy-phenyl)-5-trifluoromethyl-oxazole-4-carbonyl]-amino}-pyridin-2-ylamino)-pyrrolidine-l-carboxylic acid tert-butyl ester (150 mg, 0.249 mmol) was added trifluoroacetic acid (5 mL). When all the starting material was consumed, as indicated by TLC, the reaction mixture was concentrated to dryness. The residue was dissolved in dichloromethane (10 mL) and then cooled to 0 C.
Ethyl chloroformate (24 L, 0.249 mmol) and triethylamine (75.5 mg, 0.747 mmol) were
-117-added dropwise, and the reaction mixture was stirred for 2 h at room temperature and then concentrated. The crude product was purified by flash chromatography (Merck silica gel 60, 230-400 mesh, gradient elution with 0%-100% ethyl acetate in hexane) to give (S)-3-(5-{[2-(2-trifluoromethoxy-phenyl)-5-trifluoromethyl-oxazole-4-carbonyl]-amino}-pyridin-2-ylamino)-pyrrolidine-l-carboxylic acid ethyl ester (61 mg, 42.7%

and DGAT pellet, with a protein concentration of 9.85 mg/ml.
Aqueous buffers were prepared or purchased as follows: The coating buffer (CB) was purchased from PerkinElmer, catalog number SMP900A; the reaction buffer (RB) was 50 mM Tris-HC1, pH 7.5, 100 mM NaC1, 0.01 % BSA in water; the washing buffer (WB) to is 50 mM Tris-HC1, pH 7.5, 100 mM NaC1, 0.05 % deoxycholic acid sodium salt in water; the dilution buffer (DB) was 50 mM Tris-HC1, pH 7.5, 100 mM NaC1, 1 mM
EDTA, 0.2 % Triton X-100 in water.
1,2-Dioleoyl-sn-glycerol (DAG, 10 mmoles) was diluted to 500 M with coating buffer (CB). The diluted DAG solution was then added to 384-well PL-FlashPlates at 60 l per well, and incubated at room temperature for 2 days. The coated plates were then washed twice with washing buffer (WB) before use. Test compounds were serial diluted to 2000, 666.7, 222.2, 74.1, 24.7, 8.2, 2.7 and 0.9 M in 100 % DMSO. Diluted compound were further diluted 10 fold with reaction buffer (RB). 14C-Pal-CoA was diluted to 8.3 M
with RB. The DGAT pellet was diluted to 0.13 mg protein/ml with dilution buffer (DB) immediately before it was added to the PL-FlashPlates to start the reaction.
20 1 of the RB-diluted compounds (or 10% DMSO in RB for Total and Blank), 15 l of RB
diluted 14C-Pal-CoA and 15 l of DB diluted DGAT pellet (DB without DGAT for Blanks) were transferred to each well of the PL-FlashPlates. The reaction mixtures were incubated at 37 C for 1 hour. The reactions were stopped by washing 3 times with WB.
Plates were sealed with Top-seal and read on a Topcount instrument.
Calculation of ICSO_: The IC50 values for each compound were generated using an Excel template. The Topcount rpm readings of Total and Blank were used as 0 % and 100 %
inhibition. The percent inhibition values of reactions in the presence of compounds were calculated, and plotted against compound concentrations. All data were fitted into a Dose Response One Site model (4 parameter logistic model) as the following:
