PYRROLIDIN-2-ONE AND PIPERIDIN-2-ONE DERIVATIVES AS 11-BETA HYDROXYSTEROID DEHYDROGENASE INHIBITORS

WO 2005/108360 PCT/EP2005/051968 PYRROLIDIN-2-ONE AND PIPERIDIN-2-ONE DERIVATIVES AS 11-BETA HYDROXYSTEROID DEHYDROGENASE INHIBITORS The metabolic syndrome is a disease with increasing prevalence not only in the Western world but also in Asia and developing countries. It is characterised by obesity in particular central or visceral obesity, type 2 diabetes, hyperlipidemia, hypertension, arteriosclerosis, coronary heart diseases and eventually chronic renal failure (C.T.

Montague et al. (2000), Diabetes, 49, 883-888).

Glucocorticoids and lip-HSDl are known to be important factors in differentiation of adipose stromal cells into mature adipocytes. In the visceral stromal cells of obese patients, lip-HSDl mRNA level is increased compared with subcutaneous tissue.

Further, adipose tissue over-expression of HP-HSDl in transgenic mice is associated with increased corticosterone levels in the adipose tissue, visceral obesity, insulin sensitivity, Type 2 diabetes, hyperlipidemia and hyperphagia (H. Masuzaki et al (2001), Science, 294,2166-2170). Therefore, lip-HSDl is most likely be involved in the development of visceral obesity and the metabolic syndrome.

Inhibition of lip-HSDl results in a decrease in differentiation and an increase in proliferation of adipose stromal cells. Moreover, glucocorticoid deficiency (adrenalectomy) enhances the ability of insulin and leptin to promote anorexia and weight loss, and this effect is reversed by glucocorticoid administration (P.M. Stewart et al (2002), Trends Endocrin. Metabol, 13, 94-96). These data suggest that enhanced reactivation of cortisone by 11P-HSD1 may exacerbate obesity and it may be beneficial to inhibit this enzyme in adipose tissue of obese patients.

Obesity is also linked to cardiovascular risks. There is a significant relationship between cortisol excretion rate and HDL cholesterol in both men and women, suggesting that glucocorticoids regulate key components of cardiovascular risk. In analogy, aortic stiffness is also associated with visceral adiposity in older adults.

Glucocorticoids and glaucoma Glucocorticoids increase the risk of glaucoma by raising the intraocular pressure when administered exogenously and in certain conditions of increased production like in Cushing's syndrome. Corticosteroid-induced elevation of intra ocular pressure is caused by increased resistance to aqueous outflow due to glucocorticoid induced changes in the trabecular meshwork and its intracellular matrix. Zhou et al. (Int J Mol WO 2005/108360 PCT/EP2005/051968 Med (1998) 1, 339-346) also reported that corticosteroids increase the amounts of fibronectin as well as collagen type I and type IV in the trabecular meshwork of organ- cultured bovine anterior segments.

11P-HSD1 is expressed in the basal cells of the comeal epithelium and the non- pigmented epithelial cells. Glucocorticoid receptor mRNA was only detected in the trabecular meshwork, whereas in the non-pigmented epithelial cells mRNA for the glucocorticoid-, mineralocorticoid receptor and HP-HSDl was present. Carbenoxolone administration to patients resulted in a significant decrease in intra-ocular pressure (S.

Rauz et al. (2001), Invest. Ophtalmol. Vis. Science, 42, 2037-2042), suggesting a role for HSD1 -inhibitors in treating glaucoma.

Accordingly, the underlying problem to be solved by the present invention was to identify potent 11P-HSD inhibitors, with a high selectivity for 11P-HSD1, and the use thereof in treating pathologies associated with excess cortisol formation such as obesity, diabetes, obesity related cardiovascular diseases, and glaucoma. As shown hereinbelow, the 3-substituted 2-pyrrolidinone derivatives of formula (I) were found to be useful as a medicine, in particular in the manufacture of a medicament for the treatment of pathologies associated with excess cortisol formation.

Pure stereochemically isomeric forms of said compounds and said intermediates can be obtained by the application of art-known procedures. For example, diastereoisomers can be separated by physical methods such as selective crystallization or chromatographic techniques, e.g. counter current distribution, liquid chromatography and the like methods. Enantiomers can be obtained from racemic mixtures by first converting said racemic mixtures with suitable resolving agents such as, for example, chiral acids, to mixtures of diastereomeric salts or compounds; then physically separating said mixtures of diastereomeric salts or compounds by, for example, selective crystallization or chromatographic techniques, e.g. liquid chromatography and the like methods; and finally converting said separated diastereomeric salts or compounds into the corresponding enantiomers. Pure stereochemically isomeric forms may also be obtained from the pure stereochemically isomeric forms of the appropriate intermediates and starting materials, provided that the intervening reactions occur stereospecifically.

An alternative manner of separating the enantiomeric forms of the compounds of formula (I) and intermediates involves liquid chromatography, in particular liquid chromatography using a chiral stationary phase.

The compounds of the present invention are useful because they possess pharmacological properties. They can therefore be used as medicines, in particular to treat pathologies associated with excess cortisol formation such as for example, obesity, diabetes, obesity related cardiovascular diseases, and glaucoma.

As described in the experimental part hereinafter, the inhibitory effect of the present compounds on the liP-HSDl-reductase activity (conversion of cortison into cortisol) has been demonstrated in vitro, in an enzymatic assay using the recombinant 11b- HSD1 enzyme, by measuring the conversion of cortison into cortisol using HPLC purification and quantification methods. 1 Ip-HSDl-reductase inhibition was also demonstrated in vitro, in a cell based assay comprising contacting the cells, expressing WO 2005/108360 PCT/EP2005/051968 11P-HSD1 with the compounds to be tested and assessing the effect of said compounds on the formation of cortisol in the cellular medium of these cells. The cells preferably used in an assay of the present invention are selected from the group consisting of mouse fibroblast 3T3-L1 cells, HepG2 cells, pig kidney cell, in particular LCC-PK1 cells and rat hepatocytes.

Accordingly, the present invention provides the compounds of formula (I) and their pharmaceutically acceptable Af-oxides, addition salts, quaternary amines and stereochemically isomeric forms for use in therapy. More particular in the treatment or prevention of parthologies associated with excess cortisol formation such as obesity, diabetes, obesity related cardiovascular diseases and glaucoma. The compounds of formula (I) and their pharmaceutically acceptable iV-oxides, addition salts, quaternary amines and the stereochemically isomeric forms may hereinafter be referred to as compounds according to the invention.

In view of the utility of the compounds according to the invention, there is provided a method for the treatment of an animal, for example, a mammal including humans, suffering from a pathology associated with excess cortisol formation, which comprises administering an effective amount of a compound according to the present invention.

Said method comprising the systemic or topical administration of an effective amount of a compound according to the invention, to warm-blooded animals, including humans.

It is thus an object of the present invention to provide a compound according to the present invention for use as a medicine. In particular to use the compound according to the present invention in the manufacture of a medicament for treating pathologies associated with excess cortisol formation such as for example, obesity, diabetes, obesity related cardiovascular diseases, and glaucoma.

The amount of a compound according to the present invention, also referred to here as the active ingredient, which is required to achieve a therapeutical effect will be, of course, vary with the particular compound, the route of administration, the age and condition of the recipient, and the particular disorder or disease being treated. A suitable daily dose would be from 0.001 mg/kg to 500 mg/kg body weight, in particular from 0.005 mg/kg to 100 mg/kg body weight. A method of treatment may also include administering the active ingredient on a regimen of between one and four intakes per day.

WO 2005/108360 PCT/EP2005/051968 While it is possible for the active ingredient to be administered alone, it is preferable to present it as a pharmaceutical composition. Accordingly, the present invention further provides a pharmaceutical composition comprising a compound according to the present invention, together with a pharmaceutically acceptable carrier or diluent. The carrier or diluent must be "acceptable" in the sense of being compatible with the other ingredients of the composition and not deleterious to the recipients thereof.

The pharmaceutical compositions of this invention may be prepared by any methods well known in the art of pharmacy, for example, using methods such as those described in Gennaro et al. Remington's Pharmaceutical Sciences (IS111 éd.. Mack Publishing Company, 1990, see especially Part 8 : Pharmaceutical preparations and their Manufacture). A therapeutically effective amount of the particular compound, in base form or addition salt form, as the active ingredient is combined in intimate admixture with a pharmaceutically acceptable carrier, which 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 systemic administration such as oral, percutaneous, or parenteral administration; or topical administration such as via inhalation, a nose spray, eye drops or via a cream, gel, shampoo or the like. 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 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 pharma¬ ceutical 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 wettable agent, optionally combined with suitable additives of any nature in minor proportions, which additives do not cause any significant deleterious effects on 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 or as an ointment. As appropriate compositions for topical application WO 2005/108360 PCT/EP2005/051968 there may be cited all compositions usually employed for topically administering drugs e.g. creams, gellies, dressings, shampoos, tinctures, pastes, ointments, salves, powders and the like. Application of said compositions may be by aerosol, e.g. with a propellant such as nitrogen, carbon dioxide, a freon, or without a propellant such as a pump spray, drops, lotions, or a semisolid such as a thickened composition which can be applied by a swab. In particular, semisolid compositions such as salves, creams, gellies, ointments and the like will conveniently be used.

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 and claims 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 solutions or suspensions, teaspoonfuls, tablespoonfuls and the like, and segregated multiples thereof.

In order to enhance the solubility and/or the stability of the compounds of formula (I) in pharmaceutical compositions, it can be advantageous to employ a-, (3- or y-cyclo- dextrins or their derivatives. Also co-solvents such as alcohols may improve the solubility and/or the stability of the compounds of formula (I) in pharmaceutical compositions. In the preparation of aqueous compositions, addition salts of the subject compounds are obviously more suitable due to their increased water solubility.

Experimental part Hereinafter, the term 'RT means room temperature, 'THF' means tetrahydrofuran, 'Et20' means diethylether, 'DCM means dichloromethane, 'LDA' means (diisopropylainino)lithium.

A. Preparation of the intermediates Example A1 = O Preparation of a/ intermediate 1 S configuration WO 2005/108360 PCT/EP2005/051968 To a stirred solution of alfa-(S)-methyl benzylamine (0.05 mol) and triethylamine (EtsN) (0.055 mol) in DCM (200 ml) was added dropwise a solution of 4-chloro- butanoyl chloride (0.055 mol) in DCM (100 ml) at -10oC. After the addition, the reaction mixture was stirred at room temperature until total conversion (TLC monitoring). The reaction mixture was washed twice with IN HC1. To the organic phase were added 100 ml of 50% sodium hydroxide solution together with benzyl- triethyl ammonium chloride (0.05 mol). The mixture was stirred vigorously at room temperature overnight. The thus obtained reaction mixture was washed with IN HC1, 5% NaHCOa solution, water and brine. The organic phase was separated, dried over magnesium sulphate and concentrated to give 9.5g of intermediate 1 as colourless oil.

Alternatively intermediate 1 is prepared according to the following reaction scheme; ''Vsnh, + crY~ —*- [fYsy-if To a stirred solution of 7 ml EtjN in 300 ml CH2CI2 was introduced dropwise within 0.5 hour a solution of 6.00 g (0.0495 mol) 1 in 100 ml CH2CI2. The mixture was stirred at RT until no starting amine 1 was monitored by TLC (eluted with Et20; the formation of the intermediate 2 could be monitored R(=0.5). The mixture was washed with 2N HC1 (to remove the EtsN still present). To the reaction mixture were introduced TEBA (benzyltriethylammonium chloride) 1.13 g (0.00495 mol) and NaOH(aq.) (50 g in 60 ml H2O). The mixture was stirred overnight, organic layer was separated and acidified with 2N HC1. It was washed with NaHC03 (5%), H2O and dried (NaSO,,). After evaporation of the solvent 10.10 g crude product were isolated. It was chromatographed (column h = 260 mm, 0 = 46 mm, 195 g silicagel 230-400 mesh, eluent Et20) to give 1.43 g of intermediate 3 and 7.28 g of 4 (78%).
