Description
APOLIPOPROTEIN-B SYNTHESIS INHIBITORS
The present invention concerns novel compounds of formula (I), pharmaceutical 5 compositions comprising said compounds, the preparation thereof as well as the use as a medicine in the treatment of hyperlipidemia.
The causal relationship between hypercholesterolemia, particularly that associated with increased plasma concentrations of low density lipoproteins (LDL) and veiy low density lipoprotein (VLDL) remnants, and premature atherosclerosis has gained widespread acceptance over the last few years. The consensus that treatment of hypercholesterolemia has therapeutic benefit has become widely accepted by both physicians and the public.
A limited number of drugs are available for the treatment of hyperlipidemia. The primary agents used for die management of hyperlipidemia included bile acid sequestrants, fibrates, nicotinic acid and HMG Co A-reductase inhibitors. The inconvenience of administration and gastro-intestinal side-effects of available bile acid sequestrants make compliance a major problem. The fibrates have only limited usefulness in the treatment for certain types of hypercholesterolemia. Treatment with nicotinic acid encompasses side-effects and toxicity problems. The HMG Co A20 reductase inhibitors already form a first line treatment of familiar hypercholesterolemia. However there still remains a need for new lipid lowering agents for that act preferably via other mechanisms than the above mentioned drugs.

IH-1,2,4-triazoles having antifungal properties. The presently claimed compounds differ therefrom by the presence of a sulfur atom adjacent to the Het-moiety and by their pharmacological profile, in particular their apolipoprotein B synthesis inhibiting activity.

Compounds of formula (I) may also be converted into each other.
For instance, the compounds wherein R3 is Ci-galkyl substituted with hydroxy may be prepared by reduction of the corresponding compounds of formula (Ϊ) wherein R3 is Cj-galkyl substituted with oxo. The compounds of formula (I) wherein an endocyclic or exocyclic nitrogen atom of the heterocyclic radical 'Het is substituted with a Cj-galkyl may be prepared from the corresponding compounds wherein said endocyclic or exocyclic nitrogen atom is unsubstituted by art-known TV-alkylation reactions.
The compounds of formula (I) wherein R3 is other than hydrogen may be prepared from compounds of formula (I) wherein R3 is hydrogen by art-known /V-alkylation reactions.
The compounds of formula (I) may also be converted to the corresponding A-oxide forms following art-known procedures for converting a trivalent nitrogen into its
A'-oxide form. Said A-oxidation reaction may generally be carried out by reacting the starting material of formula (I) with an appropriate organic or inorganic peroxide. Appropriate inorganic peroxides comprise, for example, hydrogen peroxide, alkali metal or earth alkaline metal peroxides, e.g. sodium peroxide, potassium peroxide; appropriate organic peroxides may comprise peroxy acids such as, for example, benzenecarboperoxoic acid or halo substituted benzenecarboperoxoic acid, e.g. 3-chlorobenzenecarboperoxoic acid, peroxoalkanoic acids, e.g. peroxoacetic acid, alkylhydroperoxides, e.g. t.butyl hydroperoxide.

The thus formed ketone of formula (VH) is then converted into the corresponding ketal of formula (VUI) by stirring and heating the intermediate of formula (VH) with glycerol in ±e presence of an acid such as for example p-toluenesulfonic acid in a reaction inert solvent such as toluene. Finally, the hydroxylfunction of the intermediate of formula (VUI) is converted into an appropriate leaving group by artknown functional group transformation reations, such as, for example, converting the hydroxyl group into a tosylate by reaction with p-toluenesulfonylchloride .

Diastereomers may be separated by physical separation methods such as selective crystallization and chromatographic techniques, e.g. liquid chromatography. Enantiomers may be separated from each other

-9by forming diastereomeric salt forms with optically pure chiral acids and subsequent selective crystallization. Said pure stereochemically isomeric forms may also be prepared from the corresponding stereochemically isomeric forms of the appropriate starting materials, provided that the reaction occurs stereospecifically. Preferably if a specific stereochemically isomeric form is desired, said form will be synthesized by stereospecific methods of preparation. These methods will advantageously employ enantiomerically pure starting materials.
The present compounds inhibit the synthesis of apolipoprotein B as can be evidenced by 10 the results obtained in the Apolipoprotein B (apo B) inhibition test as described hereinafter. Apolipoprotein B is the principal protein component of veiy low density lipoproteins (VLDL) and low density lipoproteins (LDL). Approximately 60 to 70% of the total serum cholesterol is transported in LDL. Increased concentration of LDLcholesterol in serum is causally related to atherosclerosis. By inhibiting the synthesis of apolipoprotein B the amount of noxious low density lipoproteins is decreased.
The present compounds show no or little undesired side-effects such as, for example, albumine inhibiting activity, androgen biosynthesis inhibiting activity or cholesterol biosynthesis inhibiting activity.
In view of their apolipoprotein B inhibiting activity and concommitant lipid lowering activity the present compounds are useful as a medicine especially in a method of treating patients suffering from hyperlipidemia. In particular the present compounds may be used for the manufacture of a medicine for treating disorders caused by an excess of very low density lipoproteins (VLDL) or low density lipoproteins (LDL), and especially disorders caused by the cholesterol associated with said VLDL and LDL.
A large number of genetic and acquired diseases can result in hyperlipidemia. They can be classified into primary and secondary hyperlipidemic states. The most common causes of the secondary hyperlipidemias are diabetes mellitus, alcohol abuse, drugs, hypothyroidism, chronic renal failure, nephrotic syndrome, cholestasis and bulimia. Primary hyperlipidemias are common hypercholesterolaemia, familial combined hyperiipidaemia, familial hypercholesterolaemia, remnant hyperiipidaemia, chylomicronaemai syndrome, familial hypertriglyceridaemia. The present compounds may also be used to prevent or treat patients suffering from atherosclerosis, especially coronary atherosclerosis and more in general disorders which are related to atherosclerosis, such as ischaemic heart disease, peripheral vascular disease, cerebral vascular disease. The present compounds may cause regression of atherosclerosis and inhibit the clinical consequences of atherosclerosis, particularly morbidity and mortality.

-10Ιη view of their apolipoproteine B inhibiting activity the subject compounds may be formulated into various pharmaceutical forms for administration purposes. To prepare these pharmaceutical compositions, an effective amount of a particular compound, in base or acid addition salt form, as the active ingredient is intimately mixed with a pharmaceutically acceptable carrier. Said carrier may take a wide variety of forms depending on the form of preparation desired for administration. These pharmaceutical compositions are desirably in unitary dosage form suitable, preferably, for administration orally, rectally or by parenteral injection. For example, in preparing the compositions in oral dosage form, any of the usual pharmaceutical media may be employed, such as, for example, water, glycols, oils, alcohols and the like in the case of oral liquid preparations such as suspensions, syrups, elixirs and solutions; or solid if? carriers such as starches, sugars, kaolin, lubricants, binders, disintegrating agents and the like in the case of powders, pills, capsules and tablets. Because of their ease in administration, tablets and capsules represent the most advantageous oral dosage unit form, in which case solid pharmaceutical carriers are obviously employed. For parenteral compositions, the carrier will usually comprise sterile water, at least in large part, though other ingredients, for example, to aid solubility, may be included. Injectable solutions, for example, may be prepared in which the carrier comprises saline solution, glucose solution or a mixture of saline and glucose solution. Injectable suspensions may also be prepared in which case appropriate liquid carriers, suspending agents and the like may be employed. In the compositions suitable for percutaneous administration, the carrier optionally comprises a penetration enhancing agent and/or a suitable wetting ‘λ .. 5* agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause a significant deleterious effect to the skin. Said additives may facilitate the administration to the skin and/or may be helpful for preparing the desired compositions. These compositions may be administered in various ways, e.g., as a transdermal patch, as a spot-on, as an ointment. Acid addition salts of the compounds of formula (I) due to their increased water solubility over the corresponding base form, are obviously more suitable in the preparation of aqueous compositions.
It is especially advantageous to formulate the aforementioned pharmaceutical compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used in the specification herein refers to physically discrete units suitable as unitary dosages, each unit containing a predetermined quantity of active ingredient calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. Examples of such dosage unit forms are tablets (including scored or coated tablets), capsules, pills, powder packets, wafers, injectable

-11solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof.
Those of skill in the treatment of hyperlipidemia could easily determine the effective 5 daily amount from the test results presented hereinafter. In general it is contemplated that a therapeutically effective dose would be from 0.001 mg/kg to 5 mg/kg body weight, more preferably from 0.01 mg/kg to 0.5 mg/kg body weight, it may be appropriate to administer the therapeutically effective dose as two, three, four or more sub-doses at appropriate intervals throughout the day. Said sub-doses may be formulated as unit dosage forms, for example, containing 0.05 mg to 250 mg, and in particular 0.5 to 5 mg of active ingredient per unit dosage form.
$
The exact dosage and frequency of administration depends on the particular compound of formula (I) used, the particular condition being treated, the severity of the condition being treated, the age, weight and general physical condition of the particular patient as well as other other medication the patient may be taking, as is well known to those skilled in the art. Furthermore, it is evident that said effective daily amount may be lowered or increased depending on the response of the treated patient and/or depending on the evaluation of the physician prescribing the compounds of the instant invention.
The effective daily amount ranges mentioned hereinabove are therefore only guidelines.

C. Pharmacological example
Example 7: Apolipoprotein B fapo B) inhibition test
Cultured human liver cells (HepG2-celIs), which synthesize and secrete low-density lipoproteins, were incubated overnight at 37 “C in a liquid medium containing radinactively labelled leucine. Thus radioactively labelled leucine was incorporated into the apolipoprotein B. The liquid medium was decanted and the apolipoprotein B was isolated by means of a double immunoprecipitation, i.e. first an apolipoprotein B-specific antibody (antibody i) was added to the liquid medium and subsequently a second antibody (antibody2) was added which binds specifically to the apoB-antibodyicomplex. The thus formed apoB-antibody]-antibody2 complex precipitated and was isolated by centrifuge. Quantification of the amount of apolipoprotein B synthesized
AP . Ο Ο 7 7 9
-25during the night resulted from measuring the radioactivity of the isolated complex. To measure the inhibiting activity of the test compound, that test compound was added to the liquid medium at different concentrations and the concentration of apolipoprotein B synthesized in the presence of a test compound (concentration apoB (after)) was compared to the concentration of apolipoprotein B which was synthesized in the absence of the test compound (concentration apoB(control)). For each experiment the inhibition of apolipoprotein-B formation was expressed as kJ?
% inhibition = 100 x (1 - concentration of apoB(after)/concentration apoB(control))
When more experiments were carried out for the same concentration, the median value of the inhibition calculated for these experiments was calculated. IC50-values (concentration of the drug needed to reduce apoB secretion to 50 % of the control) were also computed.
Table 13 lists the IC50-values for some of the exemplified compounds of formula (I). Exemplified compounds of formula (I) that are not listed in Table 13, and for which data is available, have an IC50-value of 1 χ IO'6 M or more.
