The invention further relates to compositions comprising the compounds and to methods of treating atherosclerosis, obesity, and related diseases and/or conditions with the compounds.

Background Of The Invention Microsomal triglyceride transfer protein (MTP) catalyzes the transport of triglyceride, cholesteryl ester, and phospholipids. It has been implicated as a probable agent in the assembly of Apo B-containing lipoproteins, biomolecules which contribute to the formation of atherosclerotic lesions. See European Patent application publication no. 0 643 057 Al, European Patent application publication no. 0 584 446 A2, and *oo Wetterau et al., Science, 258, 999-1001, (1992). Compounds which inhibit MTP and/or otherwise inhibit Apo B secretion are accordingly useful in the treatment of atherosclerosis. Such compounds are also useful in the treatment of other diseases 20 or conditions in which, by inhibiting MTP and/or Apo B secretion, serum cholesterol and triglyceride levels can be reduced. Such conditions include hypercholesterolemia, hypertriglyceridemia, pancreatitis, and obesity; and hypercholesterolemia, hypertriglyceridemia, and hyperlipidemia associated with pancreatitis, obesity, and diabetes.

A test compound is considered to be active if it is active in any of the following screens.

The activity of a compound according to the invention can be assessed by measuring inhibition of apo B secretion in HepG2 cells.

HepG2 cells are grown in Dulbecco's Modified Eagles Medium olus 10% fetai bovine serum (growth medium; Gibco) in 96-well culture plates in a humidified atmosphere containing 5% carbon dioxide until they are approximately 70% confluent.

Test compounds are dissolved at 10-20 mM in dimethyl sulfoxide which is then diluted to 1 pM in growth medium. Serial 1:1 dilutions of this stock are made in growth medium and 100 p1 of each are added to separate wells of a 96-well culture plates 20 containing HepG2 cells. Twenty four hours later, growth medium is collected and assayed by specific EUSA for apoB and, as a control, apoAl concentrations. Inhibitors are identified as compounds that decrease apoB secretion into the medium without affecting the secretion of apoAl. The ELSA for apoB is performed as follows.

:ooo Monoclonal antibody against human apoB (Chemicon) is diluted to 5 pg/ml in 25 phosphate buffered saline/azide (PBS 0.02% Na azide) and 100 pl are added to each well of a. 96-well plate (NUNC Maxisorb). After an ovemight incubation at room 'e temperature, the antibody solution is removed and wells are washed 3 times with *oP' PBS/azide. Non-specific sites on the plastic are blocked by incubating wells for 1-3 hours in a solution of 1% bovine serum albumin (BSA) made in PBS/azide. 100 30 pl of various dilutions of growth medium from the HepG2 cells or apoB standards (made in 0.004% Tween 20/1% BSA in PBS/azide) are added to each well and incubated for 18 hours. Wells are aspirated and washed 3 times Tween 20 in PBS) prior to adding 100 p/ of a 1/1000 dilution of the secondary antibody, goat antihuman apoB (Chemicon). After a 3 hr incubation at room temperature, this solution is aspirated and the wells are again washed 3 times as above. 100 p1 of a 1:1600 dilution (in PBS/1% BSA/2mM MgCI 2 of rabbit anti-goat IgG conjugated to alkaline phosphatase (Sigma) are then added to each well and incubated for 1 hr at room temperature. After aspirating, the wells are washed 4 times as above and 100 pl of 1 mg/ml p-nitrophenylphosphate (pNPP; Sigma) in 25 mM sodium (bi)carbonate/2 mM MgC 2 pH 9.5, are added to each well and incubated for 20-30 minutes and then the reaction is terminated by the addition of 50 pl of 0.2N NaOH. Absorbance of each well is read at 405 nm and the background at 650 nm is subtracted. ApoB concentration is calculated from a standard curve constructed from purified LDL standards that are run in parallel in the same assay. ApoAl is measured in an analogous manner except that antibodies for apoAl (Chemicon) are used in place of the antibodies for apoB and antigen incubation is at 370 instead of room temperature.

Activity can also be confirmed if a test compound inhibits MTP activity directly.

Inhibition of MTP activity by a compound can be quantitated by observing the inhibition of transfer of radiolabeled triglyceride from donor vesicles to acceptor vesicles in the presence of soluble human MTP. The procedure for preparing MTP is based on the method of Wetterau and Zilversmit (Biochem. Biophys. Acta (1986) 875:610).

Briefly, human liver chunks, frozen at -80 0 C, are thawed on ice, minced, and rinsed 20 several times with ice cold 0.25 M sucrose. All subsequent steps are performed on ice.

A 50% homogenate in 0.25 M sucrose is prepared using a Potter-Elvehjem Teflon pestle. The homogenate is diluted 1:1 with 0.25 M sucrose and centrifuged at 10,000 x g for 20 min at 4°C. The pellet is resuspended in sucrose and recentrifuged at *o 10,000 x g for 20 min. The supematants are combined and the microsomes pelleted 25 by centrifugation at 105,000 x g for 75 min. The supematant is discarded and the microsomal pellet is suspended in a minimal volume of 0.25 M sucrose, diluted to 3 ml per gm starting liver weight with 0.15 M Tris-HCI pH 8.0. This suspension is divided into 12 fractions, and centrifuged at 105,000 x g for 75 min. The supematants are discarded and the microsomal pellets are stored frozen at -800C until needed. For 30 preparation of MTP prior to performing the assay, a thawed pellet is suspended in 12 ml of cold 50 mM Tris-HCI, 50 mM KCI, 5 mM MgCI, pH 7.4 and 1.2 ml of a 0.54% deoxycholate (pH 7.4) solution is added slowly with mixing to disrupt the microsomal membrane. After a 30 min incubation on ice with gentle mixing, the suspension is -31centrifuged at 105,000 x g for 75 min. The supematant, containing the soluble MTP protein, is dialyzed for 2-3 days with 4 changes of assay buffer (150 mM Tris-HCI, mM NaCI, 1 mM EDTA, 0.02% NaN3, pH The human liver MTP is stored at 4°C and diluted 1:5 with assay buffer just before use. MTP preparations show no notable loss of transfer activity with storage up to 30 days.

Uposomes are prepared under nitrogen by room temperature, bath sonication of a dispersion of 400 pM egg phosphatidylcholine 75 /M bovine heart cardiolipin, and 0.82 pM [14C]-triolein (110 Ci/mol) in assay buffer. The lipids in chloroform are added in the proper amounts and dried under a nitrogen stream before hydrating with assay buffer. Acceptor liposomes are prepared under nitrogen by room temperature bath sonication of a dispersion of 1.2 mM PC, 2.3 pM triolein and 30 pM [3H]-PC Ci/mol) in assay buffer. The donor and acceptor liposomes are centrifuged at 160,000 x g for 2 hrs at 7°C. The top 80% of the supematant, containing small unilamellar liposomes, are carefully removed and stored at 4°C until used for transfer assays.

MTP activity is measured using a transfer assay which is initiated by mixing donor and acceptor vesicles together with the soluble MTP and test compound. To 100 p1 of either a 5% BSA (control) or 5% BSA containing the test compound, are added 500 pI assay buffer, 100 p1 donor liposomes, 200 p1 acceptor liposomes and 100 pl of diluted MTP protein. After incubation at 370C for 45 min., triglyceride transfer is 20 terminated by adding 500 p1 of a 50% DEAE cellulose suspension in assay buffer.

Following 4 min of agitation, the donor liposomes, bound to the DEAE cellulose, are selectively sedimented by low speed centrifugation. An aliquot of the supernatant containing the acceptor liposomes is counted and the 3H and 14C counts are used to calculate the percent recovery of acceptor liposomes and the percent triglyceride transfer using first order kinetics. Inhibition of triglyceride transfer by test compound is manifest as a decrease in 14C radioactivity compared to controls where no test compound is present.

Activity of test compounds as MTP inhibitors can also be measured in vivo 3 according to the following test.

30 Male mice (20-30g.; various strains) are dosed by oral gavage (0.25 ml/25 g.

body weight) with test compound suspended in an aqueous 0.5% methyl cellulose solution. Compound solutions are dosed either multiple times over several days or, alternatively, once 90 minutes before mice are euthanized and blood is collected for -32preparation of serum. The serum is assayed for triglyceride concentration by a commercial enzymatic assay (Triglyceride G: Wako Fine Chemicals). MTP inhibitors are identified by their ability to lower serum triglycerides as compared to control mice dosed with vehicle.

The present invention is illustrated by the following Examples. However, it should be understood that the invention is not limited to the specific details of these examples.

The mixture was stirred for hours, basified to pH 12 with 10N sodium hydroxide solution and extracted three times with 3 liters of dichloromethane. The combined organic layers were washed with 1 liter of saturated sodium chloride solution, dried over anhydrous sodium sulfate, 30 filtered and concentrated to an oil. The oil was dissolved in 2.5 liters of methanol and saturated with anhydrous HCI gas. The resulting solution was concentrated to one liter volume and 1 liter of diethyl ether was added. The resulting precipitate was filtered, washed with diethyl ether and air dried to yield 219 g of a solid.

The reaction was then cooled to ambient temperature and extracted three times with 1 liter of dichloromethane. The combined organic layers were washed with 1 liter of saturated sodium chloride solution, dried over anhydrous sodium sulfate and concentrated to yield 173 g of an oil.
