CONFORMATIONALLY RESTRICTED AROMATIC INHIBITORS OF MICROSOMAL TRIGLYCERIDE TRANSFER PROTEIN AND METHOD

Field of the Invention This invention relates to novel conformationally restricted aromatic compounds which inhibit microsomal triglyceride transfer protein, and to methods for decreasing serum lipids and treating atherosclerosis employing such compounds.

Background of the Invention The microsomal triglyceride transfer protein (MTP) catalyzes the transport of triglyceride (TG) , cholesteryl ester (CE) , and phosphatidylcholine (PC) between small unilamellar vesicles (SUV) . etterau & Zilversmit, Che . Phvs. Lioids 3j3, 205-22 (1985) . When transfer rates are expressed as the percent of the donor lipid transferred per time, MTP expresses a distinct preference for neutral lipid transport (TG and CE) , relative to phospholipid transport. The protein from bovine liver has been isolated and characterized. Wetterau & Zilversmit, Che . Phvs. Li ^p ids .38, 205-22 (1985) . Polyacrylamide gel electrophoresis (PAGE) analysis of the purified protein suggests that the transfer protein is a complex of two subunits of apparent molecular weights 58,000 and 88,000, since a single band was present when purified MTP was electrophoresed under nondenaturing condition, while two bands of apparent molecular weights 58,000 and 88,000 were

identified when electrophoresis was performed in the presence of sodium dodecyl sulfate (SDS) . These two polypeptides are hereinafter referred to as 58 kDa and 88 kDa, respectively, or the 58 kDa and the 88 kDa component of MTP, respectively, or the low molecular weight subunit and the high molecular weight subunit of MTP, respectively.

Characterization of the 58,000 molecular weight component of bovine MTP indicates that it is the previously characterized multifunctional protein, protein disulfide isomerase (PDI) . Wetterau et al.. J. Biol. Chem. 265, 9800-7 (1990) . The presence of PDI in the transfer protein is supported by evidence showing that (1) the amino terminal 25 amino acids of the bovine 58,000 kDa component of MTP is identical to that of bovine PDI, and (2) disulfide isomerase activity was expressed by bovine MTP following the dissociation of the 58 kDa - 88 kDa protein complex. In addition, antibodies raised against bovine PDI, a protein which by itself has no TG transfer activity, were able to immunoprecipitate bovine TG transfer activity from a solution containing purified bovine MTP. PDI normally plays a role in the folding and assembly of newly synthesized disulfide bonded proteins within the lumen of the endoplasmic reticulum. Bulleid & Freedman, Nature 335, 649-51 (1988) . It catalyzes the proper pairing of cysteine residues into disulfide bonds, thus catalyzing the proper folding of disulfide bonded proteins. In addition, PDI has been reported to be identical to the beta subunit of human prolyl 4- hydroxylase. Koivu et al.. J. Biol. Chem. 262, 6447-9 (1987) . The role of PDI in the bovine transfer protein is not clear. It does appear to be an essential component of the transfer protein

as dissociation of PDI from the 88 kDa component of bovine MTP by either low concentrations of a denaturant (guanidine HCl) , a chaotropic agent (sodium perchlorate) , or a nondenaturing detergent (octyl glucoside) results in a loss of transfer activity. Wetterau et al. , Biochemistry 10., 9728- 35 (1991) . Isolated bovine PDI has no apparent lipid transfer activity, suggesting that either the 88 kDa polypeptide is the transfer protein or that it confers transfer activity to the protein complex.

The tissue and subcellular distribution of MTP activity in rats has been investigated. Wetterau & Zilversmit, Biochem. Biophvs. Acta 875, 610-7 (1986) . Lipid transfer activity was found in liver and intestine. Little or no transfer activity was found in plasma, brain, heart, or kidney. Within the liver, MTP was a soluble protein located within the lumen of the microsomal fraction. Approximately equal concentrations were found in the smooth and rough microsomes.

Abetalipoproteinemia is an autoso al recessive disease characterized by a virtual absence of plasma lipoproteins which contain apolipoprotein B (apoB) . Kane & Havel in The Metabolic Basis of Inherited Disease, Sixth edition, 1139-64 (1989) . Plasma TG levels may be as low as a few mg/dL, and they fail to rise after fat ingestion. Plasma cholesterol levels are often only 20-45 mg/dL. These abnormalities are the result of a genetic defect in the assembly and/or secretion of very low density lipoproteins (VLDL) in the liver and chylomicrons in the intestine. The molecular basis for this defect has not been previously determined. In subjects examined, triglyceride, phospholipid, and cholesterol synthesis appear normal. At autopsy, subjects are

free of atherosclerosis. Schaefer et al.. Clin. Chem. 34, B9-12 (1988) . A link between the apoB gene and abetalipoproteinemia has been excluded in several families. Talmud et al. , J. Clin. Invest. 82, 1803-6 (1988) and Huang et al.. Am. J. Hum. Genet. 46, 1141-8 (1990) .

Subjects with abetalipoproteinemia are afflicted with numerous maladies. Kane __ Havel, supra. Subjects have fat malabsorption and TG accumulation in their enterocytes and hepatocytes. Due to the absence of TG-rich plasma lipoproteins, there is a defect in the transport of fat-soluble vitamins such as vitamin E. This results in acanthocytosis of erythrocytes, spinocerebellar ataxia with degeneration of the fasciculus cuneatus and gracilis, peripheral neuropathy, degenerative pigmentary retinopathy, and ceroid myopathy. Treatment of abetalipoproteinemic subjects includes dietary restriction of fat intake and dietary supplementation with vitamins A, E and K.

In vitro, MTP catalyzes the transport of lipid molecules between phospholipid membranes. Presumably, it plays a similar role in vivo, and thus plays some role in lipid metabolism. The subcellular (lumen of the microsomal fraction) and tissue distribution (liver and intestine) of MTP have led to speculation that it plays a role in the assembly of plasma lipoproteins, as these are the sites of plasma lipoprotein assembly. Wetterau & Zilversmit, Biochem. Biophvs. Acta 875, 610-7 (1986) . The ability of MTP to catalyze the transport of TG between membranes is consistent with this hypothesis, and suggests that MTP may catalyze the transport of TG from its site of synthesis in the endoplasmic reticulum (ER) membrane to nascent lipoprotein particles within the lumen of the ER.

Olofsson and colleagues have studied lipoprotein assembly in HepG2 cells. Bostrom et al.. J. Biol. Chem. 263, 4434-42 (1988) . Their results suggest small precursor lipoproteins become larger with time. This would be consistent with the addition or transfer of lipid molecules to nascent lipoproteins as they are assembled. MTP may play a role in this process. In support of this hypothesis, Howell and Palade, J. Cell Biol. 32 _. , 833-45 (1982) , isolated nascent lipoproteins from the hepatic Golgi fraction of rat liver. There was a spectrum of sizes of particles present with varying lipid and protein compositions. Particles of high density lipoprotein (HDL) density, yet containing apoB, were found. Higgins and Hutson, J. Lipid Res. 25, 1295-1305 (1984), reported lipoproteins isolated from Golgi were consistently larger than those from the endoplasmic reticulum, again suggesting the assembly of lipoproteins is a progressive event. However, there is no direct evidence in the prior art demonstrating that MTP plays a role in lipid metabolism or the assembly of plasma lipoprotein. Recent reports (Science, Vol. 258, page 999, 1992; D. Sharp et al, Nature, Vol. 365, page 65, 1993) demonstrate that the defect causing abetalipoproteinemia is in the MTP gene, and as a result, the MTP protein. Individuals with abetalipoproteinemia have no MTP activity, as a result of mutations in the MTP gene, some of which have been characterized. These results indicate that MTP is required for the synthesis of apoB containing lipoproteins, such as VLDL, the precursor to LDL. It therefore follows that inhibitors of MTP would inhibit the synthesis of VLDL and LDL, thereby lowering VLDL levels, LDL

levels, cholesterol levels, and triglyceride levels in animals and man.

This provides further support for the proposal that an MTP inhibitor would lower apoB containing lipoprotein and lipid levels in vivo.

The compounds of the invention may be employed in preventing, stabilizing or causing regression of atherosclerosis in a mammalian species by administering a therapeutically effective amount of a compound to decrease the activity of MTP.

The compounds of the invention can be tested for MTP inhibitory activity employing the procedures set out in U.S. application Serial No. 117,362 filed September 3, 1993, employing MTP isolated from one of the following sources: (1) bovine liver microsomes, (2) HepG ₂ cells (human hepatoma cells) or

(3) recombinant human MTP expressed in baculovirus. The compounds of the invention may also be employed in lowering serum lipid levels, such as cholesterol or triglyceride (TG) levels, in a mammalian species, by administering a therapeutic¬ ally effective amount of a compound to decrease the activity of MTP.

The compounds of the invention may be employed in the treatment of various other conditions or diseases using agents which decrease activity of MTP. For example, compounds of the invention decrease the amount or activity of MTP and therefore decrease serum cholesterol and TG levels, and TG, fatty acid and cholesterol absorption and thus are useful in treating hypercholesterolemia, hypertriglyceridemia, hyperlipidemia, pancreatitis, hyperglycemia and obesity.

The compounds of the present invention are agents that decrease the activity of MTP and can be administered to various mammalian species, such as monkeys, dogs, cats, rats, humans, etc. , in need of such treatment. These agents can be administered systemically, such as orally or parenterally.

The agents that decrease the activity or amount of MTP can be incorporated in a conventional systemic dosage form, such as a tablet, capsule, elixir or injectable formulation. The above dosage forms will also include the necessary physiologically acceptable carrier material, excipient, lubricant, buffer, antibacterial, bulking agent (such as mannitol) , anti-oxidants (ascorbic acid or sodium bisulfite) or the like. Oral dosage forms are preferred, although parenteral forms are quite satisfactory as well. The dose administered must be carefully adjusted according to the age, weight, and condition of the patient, as well as the route of administration, dosage form and regimen, and the desired result. In general, the dosage forms described above may be administered in amounts of from about 5 to about 500 mg per day in single or divided doses of one to four times daily.

The following Examples represent preferred embodiments of the .invention. All temperatures are in °C unless indicated otherwise.

9- (3-Phenylpropyl) -N- (3-hydroxy)propyl-9H-xanthene- 9-carboxamide

A. 9- (3-Phenylpropyl)-9H-xanthene-9- carboxylic acid

To a solution of 10 g (44 mmol, 1 eq) of 9- xanthenylcarboxylic acid in 200 mL of THF at 0°C was added 37.2 mL (93 mmol, 2.1 eq) of a 2.5 M solution of n-butyllithium in hexanes dropwise over 15 min. (First equivalent resulted in precipitation of Li salt of the carboxylate; solution became homogeneous as dianion formed. ) The resulting orange solution of dianion was stirred at 0°C for 10 min and 9.4 mL (62 mmol, 1.4 eq) of 1-bromo-3-phenyIpropane was added quickly over 3 min. The reaction was stirred at 0°C and allowed to warm to RT as the ice bath melted.

After 16 h, the basic reaction mixture (pH -14) was extracted with water (3 x 100 mL) . The combined aqueous layers were acidified (to pH -1) with 6 N HCl and extracted with ether (3 x 100 mL) . The combined ether solutions were dried (MgS0 ₄ ) , filtered and concentrated to afford 17.04 g of a viscous golden oil. The oil was dissolved in hot hexanes using a small amount of CH ₂ C1 ₂ to effect complete dissolution. Concentration of this solution resulted in a yellow solid which was recrystallized from ether/hexanes to afford 13.3 g

(88%) of title compound as a white crystalline solid, m.p. 137-138°C.

B. 9- (3-Phenylpropyl)-9H-xanthene-9- carboxylic acid, 4-nitrophenvl ester

To a solution of 10 g (29.0 mmol, 1 eq) of Part A compound in 100 mL of CH ₂ CI ₂ was added 100 μL of DMF. The solution was cooled to 0°C and 22.0 mL (43.6 mmol, 1.5 eq) of a 2.0 M oxalyl chloride solution in CH ₂ C1 ₂ was added over 5 min. The resulting bubbling solution was stirred at 0°C for 1.5 h (until bubbling had ceased) . The solution was concentrated and the residual oil was taken up in 50 mL of CH ₂ CI ₂ and reconcentrated. The resulting oil was dissolved in 150 mL of CH ₂ C1 ₂ and 188 mg (1.52 mmol, 0.05 eq) of 4-dimethylamino- pyridine was added. The solution was cooled to 0°C and 4.9 mL (34.8 mmol, 1.2 eq) of triethylamine was added. To the resulting dark brown cloudy solution was added 12.1 g (87.1 mmol, 3 eq) of p-nitrophenol as a solid. Upon addition the reaction quickly became clear and the resulting clear reaction

mixture was allowed to warm to RT as the ice bath melted. (TLC indicated the reaction was essentially complete after 40 min.) After 15 h, the reaction was washed with 100 mL of ice-cold 1 N HCl. The organic solution was filtered through cotton and concentrated to afford 24.22 g of a viscous golden-brown oil which was chromatographed on silica gel (200 g) eluted with 25% hexanes in CH ₂ C1 ₂ to afford 13.45 g of a viscous golden oil. The product was cystallized by concentrating down a ether/hexane solution and the crude solid was then recrystallized from ether/hexanes to afford 11.8 g (87%) of title compound as an off-white crystalline solid, m.p. 93-94°C.

(PS)= 1 % Divinylbenzene cross-linked polystyrene resin, 100-200 mesh

To a magnetically stirred suspension of 4.8 g (120 mmol, 10 eq) of sodium hydride (60% mineral oil dispersion) in 30 mL of dimethylformamide (DMF) at 0 °C was added a solution of 18.2 g (120 mmol, 10 eq) of 4-hydroxy-2-methoxybenzaldehyde in 50 mL of DMF dropwise over 75 min. The reaction was allowed to warm to room temperature (RT) and stirred for an additional 75 min. The stirbar was removed and 10 g (12 mmol, 1 eq) of Merrifield resin (loading of 1.2 mmol/g, Advanced Chemtech) was added. The flask was placed in a heating mantel mounted on a vortex mixer and heated at 70"C (internal temperature) while vortexing for 26 h. The contents of the reaction vessel were transferred to a large filter funnel with a scintered-glass frit (porosity C) and rinsed sequentially with DMF (3 x 100 mL) , 1:1 DMF:water (3 x 100 mL) , water (2 x 100 mL) and MeOH (5 x 100 mL) . The resin was dried under high vacuum (0.1 mm Hg) for 72 h to afford 11.16 g (98% of expected weight) of title product as a tacky non-freeflowing tan resin. The resin was characterized by gel- phase ¹³ C-NMR and elemental analysis (chlorine and oxygen) .

Elemental Analysis:

Chlorine: Expected 0% Cl for 100% loading; found 0.21%. Starting Cl content of resin was 4.26%. Residual Cl consistent with 95% resin loading. Oxygen: Expected 5.76% for 100% loading; found 6.21%.

The reaction was allowed to warm to room temperature (RT) and stirred for an additional 75 min. The stirbar was removed and 10 g (12 mmol, 1 eq) of Merrifield resin (with a loading of 1.2 mmol/g (Advanced Chemtech) ) was added. The flask was placed in a heating mantel mounted on a vortex mixer and heated at 70'C (internal temper-ature) while vortexing for 26 h. The contents of the reaction vessel were transferred to a large filter funnel with a scintered-glass frit (porosity C) and rinsed

sequentially with DMF (3 x 100 mL) , 1:1 DMF:water (3 x 100 mL) , water (2 x 100 mL) and MeOH (5 x 100 mL) . The resin was dried under high vacuum (0.1 mm Hg) for 72 h to afford 11.16 g (98% of expected weight) of title compound as a tacky non- freeflowing tan resin. The resin was characterized by gel-phase ¹³ C-NMR and elemental analysis (chlorine and oxygen) .

Elemental Analysis:

Chlorine: Expected 0% Cl for 100% loading; found

0.21%. Starting Cl content of resin was 4.26%.

Residual Cl consistent with 95% resin loading.

Oxygen: Expected 5.76% for 100% loading; found 6.21%.
