Abstract: The present invention relates to A compound of formula (I) wherein A, U, V, X, Z, R<1>, Y, R<2> and R<3> are defined in the description or a physiologically acceptable salt, solvate or derivative thereof, to compositions and processes for making said compounds and their use in treating conditions ameliorated by an apoB-100 and/or MTP inhibitor.

Description: BIOISOSTERIC BENZAMIDE DERIVATIVES AND THEIR USE AS APoB-100 SECRETION INHIBITORS This invention relates to the use of compounds to inhibit hepatic production of apoprotein B-100 (apoB-100) and intestinal production of chylomicrons or apoprotein B-48 (apoB-48) and MTP. ApoB-100 is the main protein component of low density lipoprotein-cholesterol (LDL-c). High LDL-c plasmatic levels are a major risk factor for atherosclerosis and coronary artery diseases. ApoB-48 is the main protein component of chylomicrons. The microsomal triglyceride transfer protein (MTP) catalyses the transfer of triglycerides, cholesteryl esters and phosphatidylcholine between small unilamellar vesicles. MTP is expressed in liver and intestine, both organs which produce lipoproteins. MTP is able to lipidate neosynthesized apoB-100 within the liver, and neosynthesized apoB-48 within the intestine, therefore leading to the production of triglyceride-rich lipoparticles such as VLDL and chylomicrons respectively. Thus, MTP inhibitors have the potential to decrease LDL-c and triglyceride plasmatic levels, and also intestinal lipid absorption. MTP inhibitors may be used in the treatment of non-insulin dependent diabetes mellitus, coronary heart disease, pancreatitis, hypercholesterolemia, hypertriglyceridemia, hyperlipemia, mixed dyslipidemia, post-prandial hyperlipemia, atherosclerosis and obesity. Compounds having apoB-100 and MTP inhibition properties have been described in WO96/40640.

Such derivatives are clear to those skilled in the art, without undue experimentation, and with reference to the teaching of Burger's Medicinal Chemistry And Drug Discovery, 5th Edition, Vol 1 : Principles And Practice, which is incorporated herein by reference. The compounds of the invention are inhibitors of hepatic production of apoB- 100 and MTP and are thus of use in the treatment of conditions ameliorated by an apoB-100 and / or MTP inhibitor. The ability of the compounds of this invention to inhibit human MTP activity is measured by an in vitro assay where MTP tranfers 3H-triolein between phosphatidylcholine liposomes. The specificity of the compounds of the invention is established by comparing the effects on apoB-100 and apoprotein A-1 production. A specificity of at least 100 is preferred. The in vivo profile of the compounds is determined by acute oral administration of the compounds of the invention to DBA/2 mice and Wistar rats. Potency of the active compounds is evaluated by measuring plasmatic lipids (total cholesterol, triglyceride, LDL cholesterol and HDL cholesterol) and apoproteins (apoB-100, apoB-48 and apoA-1). - ~ ~ , The compounds of the invention are potent and specific inhibitors of hepatic production of apoB-100 and MTP, which furthermore exhibit good oral bioavailability and duration of action. Compounds of the invention are of use in the treatment of atherosclerosis, pancreatitis, non-insulin dependent diabetes mellitus (NIDDM), coronary heart diseases and obesity. Compounds of the invention are also useful in lowering serum lipid levels, cholesterol and/or triglycerides, and are of use in the treatment of hyperlipidemia, post-prandial hyperlipemia, mixed dyslipidemia, hyperlipoproteinemia, hypercholesterolemia and/or hypertriglyceridemia. The invention therefore provides a compound of formula (I) or a physiologically acceptable salt, solvate or derivative thereof for use in therapy, in particular in human medicine. There is also provided as a further aspect of the invention the use of a compound of formula (I) or a physiologically acceptable salt, solvate or derivative thereof in the preparation of a medicament for use in the treatment of conditions ameliorated by an apoB-100 and / or MTP inhibitor. In an alternative or further aspect, there is provided a method for the treatment of a mammal, including man, comprising administration of an effective amount of a compound of formula (I) or a physiologically acceptable salt, solvate or derivative thereof in particular in the treatment of conditions ameliorated by an apoB-100 and / or MTP inhibitor. It will be appreciated that reference to treatment is intended to include prophylaxis as well as the alleviation of established symptoms. Compounds of formula (I) may be administered as the raw chemical but the active ingredient is preferably presented as a pharmaceutical formulation. Accordingly, the invention also provides a pharmaceutical composition which comprises at least one compound of formula (I) or a physiologically acceptable salt, solvate or derivative thereof and formulated for administration by any convenient route. Such compositions are preferably in a form adapted for use in medicine, in particular human medicine, and can conveniently be formulated in a conventional manner using one or more pharmaceutically acceptable carriers or excipients. Thus compounds of formula (I) may be formulated for oral, buccal, parenteral, transdermal, topical (including ophthalmic and nasal), depot or rectal administration or in a form suitable for administration by inhalation or insufflation (either through the mouth or nose). The compounds of formula (I) may, if desired, be administered with one or more therapeutic agents and formulated for administration by any convenient route in a conventional manner. Appropriate doses will be readily appreciated by those skilled in the art. For example, the compounds of forrnula (I) may be administered in combination with an HMG CoA reductase inhibitor. A compound of formula (I), or a physiologically acceptable salt, solvate or derivative thereof, may be prepared by the general methods outlined hereafter. In the following description, the groups A, U, V, X, Y, Z, R 1 , R 2 and R 3 are as previously defined for compounds of formula (I), unless specified otherwise. According to a general process (A), a compound of formula (I) may be prepared by reacting a compound of formula (II) with a compound of formula R 1 -Z-X-L (ID where L represents a suitable halide leaving group, e.g. chloride or bromide, under standard displacement conditions, or where X is an oxo group, L may additonally represent a hydroxy group, the reaction being effected under standard acid and amine coupling conditions. A compound of formula (II) may be prepared by reaction of a compound of formula (III) with a compound of formula (IV) (III) (IV) where L is defined above and P is a suitable amine protecting group, e.g. tert- butoxycarbonyl (Boc) or benzyl, under standard coupling conditions for an acid and amine coupling, followed by deprotection of the protecting group under suitable conditions, e.g. acidic removal of a Boc group or hydrogenation of the benzyl group. A compound of formula (IV), where A represents N, may be prepared by the two step reaction of a compound of formula (V) (V) comprising incorporation of the protecting group P using standard methodology followed by reduction of the nitro group, e.g. under hydrogenation conditions or by SnCI2 reduction. A compound of formula (IV) may alternatively be prepared by reaction of a compound (Va) with a compound (Vb) (Va) (Vb) where L is a suitable leaving group such as chloride or bromide and P is a suitable N-protecting group as descibed above, followed by reduction of the nitro group, e.g. under hydrogenation conditions or by SnCI2 reduction. A compound of formula (IV), where A represents CH, may be prepared from a compound of formula (VI) . (VI) where P is defined above, by reaction with a suitable a compound of formula H 2 N-P' where P' is a suitable protecting group which is labile under hydrogenation conditions, such as a benzyl group, using a suitable coupling agent or agents such as tris(dibenzylidene acetone)dipalladium, 2,2'- bis(diphenylphosphino)-1 ,1'-binaphthyl (binap) and sodium tert-butoxide in a suitable solvent such as toluene, followed by removal of the protecting group and reduction of the double bond under hydrogenation conditions. According to a second method (B), compounds of formula (I) may be prepared by reaction of compounds of formula (III) and compounds of formula (VII) where L is defined above, under standard coupling conditions. Compounds of formula (VII) may be prepared by reaction of a compound of formula (V) with a compound of formula R 1 -Z-X-L, where L is defined above, followed by reduction of the nitro group under hydrogenation or reductive tin chloride conditions. Alternatively, compounds of formula (VII) may be prepared from a compound of formula (Vila) (Vila) comprising deprotection of N-protecting group P under standard conditions, followed by reaction of the resulting compound with R 1 -Z-X-L, as defined above, followed by reduction of the nitro group under standard conditions. According to a third process (C), a compound of formula (I) where Y is -O-C,. 4 a!kylene- may be prepared by reaction of a compound of formula (VIII) with a compound of formula R^C^alkylene-L, where L is defined above, (Viii) _ ~ Compounds of formula (VIII) may be prepared according to the process outlined in process B. According to a fourth general process (D), a compound of formula (I), where at least part of X represents an alkylene link to the piperidine or piperazine group, may be prepared by reacting a compound of formula (II) with a compound of formula (IX) (II) where X' represents X minus a methylene group, under standard reductive amination conditions, e.g. using sodium triacetoxyborohydride in a solvent such as dichloroethane. According to a fifth process (E), a compound of formula (I) may be prepared from a different compound of formula (I), using standard techniques well known in the art. For example, compounds of formula (1) where R 1 comprises a group containing an amide group may be prepared from the compound of formula (I) where the corresponding position comprises a carboxylic acid group, which in turn may be prepared from the compound of formula (I) where the corresponding position comprises a carboxylic ester group. Well known methods in the art may be employed to facilitate the transformation of an ester to an acid and then to an amide. A compound of formula (III), where Y is a direct link, R 2 is a phenyl or an aromatic heterocyclyl and L is a hydroxy group, may be prepared firstly by coupling a boronic acid with a suitable leaving group, represented by a compound of formula (X) and a compound of formula (XI) where R 2 ' represents phenyl or an aromatic heterocyclyl, PG represents a protected carboxylic acid and A and D represent either the boronic acid or the suitable leaving group, such as triflate or bromide, followed by deprotection of the protecting group under standard conditions, such as base removal of an ester group. Where L represents a halide leaving group, the carboxylic acid product can be treated with a suitable reagent, such as thionyl chloride, to give the corresponding chloride leaving group. Where R 1 is a phenyl, substituted by an aromatic heterocyclyl, the aromatic heterocyclyl may be introduced by any well known methods in the art. For instance, where the substituent is a methyl substituted oxadiazole, this may be formed by treatment of a suitable benzamide derivative with a suitable reagent, such as dimethylacetamide dimethylacetal at elevated temperature, followed by cyclisation of the intermediate compound with hydoxylamine. The various general methods described above may be useful for the introduction of the desired groups at any stage in the stepwise formation of the required compound, and it will be appreciated that these general methods can be combined in different ways in such multi-stage processes. The sequence of the reactions in multi-stage processes should of course be chosen so that the reaction conditions used do not affect groups in the molecule which are desired in the final product. ~ ι Compounds of formula R 1 -Z-X-L, (III), (V), (Va), (Vb) (VI), (IX), (X), (Xa) and (XI) are known or may be prepared by standard methods well known in the art and/or herein described. Physiologically acceptable salts may also be prepared from other salts, including other physiologically acceptable salts, of the compound of formula (I) using conventional methods. The compounds of formula (I) may readily be isolated in association with solvent molecules by crystallisation from or evaporation of an appropriate solvent to give the corresponding solvates. ι When a specific enantiomer of a compound of general formula (I) is required, this may be obtained for example by resolution of a corresponding enantiomeric mixture of a compound of formula (I) using conventional methods. Thus, in one example an appropriate optically active acid may be used to form salts with the enantiomeric mixture of a compound of general formula (I). The resulting mixture of isomeric salts may be separated, for example, by fractional crystallisation into the diastereoisomeric salts from which the required enantiomer of a compound of general formula (I) may be isolated by conversion into the required free base. Alternatively, enantiomers of a compound of general formula (I) may be synthesised from the appropriate optically active intermediates using any of the general processes described herein.

Biological Assay ApoB-100 Assay Primary human hepatocytes were seeded at 50 000 cells/well in 96 well plates. After an overnight adhesion phase, cells were incubated with compounds for 8 hours in RPMI medium containing 1% FCS, 4 μg/ml insulin, 100 nM dexamethasone and 50 μCi/ml 35 S-methionine. Compounds were dissolved in DMSO and tested onto cells from 1 μM to 1.6 nM. Production of radiolabeled apoB-100 and apoA-1 (used as a selectivity control) was quantified by analysis of supernatants using SDS PAGE and exposure of gels onto Phosphorimager screens. Inhibition of apoB-100 and apoA-1 secretion by compounds was calculated taking untreated cells as controls, and IC 50 of each compound was determined on both apoproteins. MTP Assay The human MTP activity assay was established using SPA technology. Donor liposomes were prepared with 3H-triolein and phosphatidylcholine, while acceptor liposomes contained biotinylated phosphatidylethanolamine and phosphatidylcholine. The MTP-mediated 3H-triolein transfer onto acceptor liposomes was allowed by a 25 min incubation at 37°C, and quantified by the addition of streptavidin-SPA beads.
