TRIAZINE 11-BETA HYDROXYSTEROID DEHYDROGENASE TYPE I

INHIBITORS

BACKGROUND OF THE INVENTION [0001] The steroid hormone Cortisol is a key regulator of many physiological processes. However, an excess of Cortisol, as occurs in Cushing's Disease, provokes severe metabolic abnormalities including: type 2 diabetes, cardiovascular disease, obesity, and osteoporosis. Many patients with these diseases, however, do not show significant increases in plasma Cortisol levels. In addition to plasma Cortisol, individual tissues can regulate their glucocorticoid tone via the in situ conversion of inactive cortisone to the active hormone Cortisol. Indeed, the normally high plasma concentration of cortisone provides a ready supply of precursor for conversion to Cortisol via the intracellular enzyme 11-beta-hydroxysteroid dehydrogenase type I (11-beta-HSDl). [0002] 11-beta-HSDl is a member of the short chain dehydrogenase superfamily of enzymes. By catalyzing the conversion of biologically inactive cortisone to Cortisol, 11-beta-HSDl controls the intracellular glucocorticoid tone according to its expression and activity levels. In this manner, 11-beta-HSDl can determine the overall metabolic status of the organ. 11-beta-HSDl is expressed at high levels in the liver and at lower levels in many metabolically active tissues including the adipose, the CNS, the pancreas, and the pituitary. Taking the example of the liver, it is predicted that high levels of 11-beta-HSDl activity will stimulate gluconeogenesis and overall glucose output. Conversely, reduction of 11-beta-HSDl activity will downregulate gluconeogenesis resulting in lower plasma glucose levels. [0003] Various studies have been conducted that support this hypothesis. For example, transgenic mice expressing 2X the normal level of 11-beta-HSDl in only the adipose tissue show abdominal obesity, hyperglycemia, and insulin resistance. (H. Masuzaki, J. Paterson, H. Shinyama, N.M. Morton, JJ. Mullins, J.R. Seckl, J. S. Flier, A Transgenic Model of Visceral Obesity and the Metabolic Syndrome, Science 294:2166-2170 (2001). Conversely, when the 11-beta-HSDl gene is ablated by homologous recombination, the resulting mice are resistant to diet induced obesity and the accompanying dysregulation of glucose metabolism (N.M. Morton, J.M.

Paterson, H. Masuzaki, M.C. Holmes, B. Staels, C. Fievet, B.R. Walker, J.S. Flier, JJ. Mullings, J.R. Seckl, Novel Adipose Tissue-Mediated Resistance to Diet-induced Visceral Obesity in 11 β-Hydroxysteroid Dehydrogenase Type 1 -Deficient Mice. Diabetes 53: 931-938 (2004). In addition, treatment of genetic mouse models of obesity and diabetes (ob/ob, db/db and KKAy mice) with a specific inhibitor of 11- beta-HSDl causes a decrease in glucose output from the liver and an overall increase in insulin sensitivity (P. Alberts, C. Nilsson, G. Selen, L.O.M. Engblom, N.H.M. Edling, S. Norling, G. Klingstrom, C. Larsson, M. Forsgren, M. Ashkzari, CE. Nilsson, M. Fiedler, E. Bergqvist, B. Ohman, E. Bjorkstrand, L.B. Abrahmsen, Selective Inhibition of 11 β-Hydroxysteroid Dehydrogenase Type I Improves Hepatic Insuling Sensuitivity in Hyperglycemic Mice Strains, Endocrinology 144: 4755-4762 (2003)). Based in part on these studies, it is believed that local control of Cortisol levels is important in metabolic diseases in these model systems. In addition, the results of these studies also suggest that inhibition of 11-beta-HSDl will be a viable strategy for treating metabolic diseases such as type 2 diabetes, obesity, and the metabolic syndrome.

[0004] Lending further support to this idea are the results of a series of preliminary clinical studies. For example, several reports have shown that adipose tissue from obese individuals has elevated levels of 11-beta-HSDl activity. In addition, studies with carbenoxolone, a natural product derived from licorice that inhibits both 11-beta-HSDl and l l-beta-HSD2 (converts Cortisol to cortisone in kidney) have shown promising results. A seven day, double blind, placebo controlled, cross over study with carbenoxolone in mildly overweight individuals with type 2 diabetes showed that patients treated with the inhibitor, but not the placebo group, displayed a decrease in hepatic glucose production (R.C. Andrews, O. Rooyackers, B.R. Walker, J. Clin. Endocrinol. Metab. 88: 285-291 (2003)). This observation is consistent with the inhibition of 11-beta-HSDl in the liver. Furthermore, another clinical study reported that the inhibition of 11-beta-HSDl may provide a novel treatment option for patients with glacoma (Rauz et al., IOVS, Vol. 42, No. 9, pp. 2037-2042 (August 2001)). The results of these preclinical and early clinical studies strongly support the concept that treatment with a potent and selective

inhibitor of 11-beta-HSDl will be an efficacious therapy in patients afflicted with various disorders.

DEFINITIONS

[0038] The compounds herein described may have asymmetric centers. Compounds of the present invention containing an asymmetrically substituted atom may be isolated in optically active or racemic forms. It is well known in the art how to prepare optically active forms, such as by resolution of racemic forms or by synthesis from optically active starting materials. Many geometric isomers of olefins, C=N double bonds, and the like can also be present in the compounds described herein, and all such stable isomers are contemplated in the present invention. Cis and trans geometric isomers of the compounds of the present invention are described and may be isolated as a mixture of isomers or as separated isomeric forms. All chiral, diastereomeric, racemic forms and all geometric isomeric forms of a structure are intended, unless the specific stereochemistry or isomeric form is specifically indicated.

[0039] One enantiomer of a compound of Formula I may display superior activity compared with the other. Thus, all of the stereochemistries are considered to be a part of the present invention. When required, separation of the racemic material can be achieved by HPLC using a chiral column or by a resolution using a resolving agent such as camphonic chloride as in Steven D. Young, et al, Antimicrobial Agents and Chemother aphy, 1995, 2602-2605. [0040] To the extent that compounds of the formula I, and salts thereof, may exist in their tautomeric form, all such tautomeric forms are contemplated herein as part of the present invention.

[0041] The term "substituted," as used herein, means that any one or more hydrogens on the designated atom or ring is replaced with a selection from the indicated group, provided that the designated atom's or ring atom's normal valency is not exceeded, and that the substitution results in a stable compound. When a substitent is keto (i.e., =0), then 2 hydrogens on the atom are replaced. [0042] When any variable (e.g., R ₄ ) occurs more than one time in any constituent or formula for a compound, its definition at each occurrence is independent of its definition at every other occurrence. Thus, for example, if a group is shown to be substituted with (R _A ) ₁₁₁ and m is 0-3, then said group may optionally be substituted with up to three R ₄ groups and R ₄ at each occurrence is selected independently from

the definition of R ₄ . Also, combinations of substituents and/or variables are permissible only if such combinations result in stable compounds. [0043] When a bond to a substituent is shown to cross a bond connecting two atoms in a ring, then such substituent may be bonded to any atom on the ring. When a substituent is listed without indicating the atom via which such substituent is bonded to the rest of the compound of a given formula, then such substituent may be bonded via any atom in such substituent. Combinations of substituents and/or variables are permissible only if such combinations result in stable compounds.

[0061] The term "cyano" as used herein, refers to a -CN group. [0062] The term "nitro" as used herein, refers to an -NO ₂ group. [0063] The term "hydroxy" as used herein, refers to an OH group. [0064] The phrase "pharmaceutically acceptable" is employed herein to refer to those compounds, materials, compositions, and/or dosage forms which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of human beings and animals without excessive toxicity, irritation, allergic response, or other problem or complication, commensurate with a reasonable benefit/risk ratio. [0065] As used herein, "pharmaceutically acceptable salts" refer to derivatives of the disclosed compounds wherein the parent compound is modified by making acid or base salts thereof. Examples of pharmaceutically acceptable salts include, but are not limited to, mineral or organic acid salts of basic residues such as amines; alkali or organic salts of acidic residues such as carboxylic acids; and the like. The pharmaceutically acceptable salts include the conventional non-toxic salts or the quaternary ammonium salts of the parent compound formed, for example, from nontoxic inorganic or organic acids. For example, such conventional non-toxic salts

include those derived from inorganic acids such as hydrochloric, hydrobromic, sulfuric, sulfamic, phosphoric, nitric and the like; and the salts prepared from organic acids such as acetic, propionic, succinic, glycolic, stearic, lactic, malic, tartaric, citric, ascorbic, pamoic, maleic, hydroxymaleic, phenylacetic, glutamic, benzoic, salicylic, sulfanilic, 2-acetoxybenzoic, fumaric, toluenesulfonic, methanesulfonic, ethane disulfonic, oxalic, isethionic, and the like.

[0066] The pharmaceutically acceptable salts of the present invention can be synthesized from the parent compound which contains a basic or acidic moiety by conventional chemical methods. Generally, such salts can be prepared by reacting the free acid or base forms of these compounds with a stoichiometric amount of the appropriate base or acid in water or in an organic solvent, or in a mixture of the two; generally, nonaqueous media like ether, ethyl acetate, ethanol, isopropanol, or acetonitrile are preferred. Lists of suitable salts are found in Remington 's Pharmaceutical Sciences, 17th ed., Mack Publishing Company, Easton, PA, 1985, p. 1418, the disclosure of which is hereby incorporated by reference.

[0067] Any compound that can be converted in vivo to provide the bioactive agent (i.e., the compound of formula I) is a prodrug within the scope and spirit of the invention.

[0068] The term "prodrugs" as employed herein includes esters and carbonates formed by reacting one or more hydroxyls of compounds of formula I with alkyl, alkoxy, or aryl substituted acylating agents employing procedures known to those skilled in the art to generate acetates, pivalates, methylcarbonates, benzoates, and the like. [0069] Various forms of prodrugs are well known in the art and are described in: a) The Practice of Medicinal Chemistry, Camille G. Wermuth et al, Ch.

31, (Academic Press, 1996); b) Design of Prodrugs, edited by H. Bundgaard, (Elsevier, 1985); c) A Textbook of Drug Design and Development, P. Krogsgaard-Larson and H. Bundgaard, eds. Ch. 5, pgs 113 - 191 (Harwood Academic Publishers, 1991); and d) Hydrolysis in Drug and Prodrug Metabolism, Bernard Testa and Joachim M. Mayer, (Wiley-VCH, 2003).

Said references are incorporated herein by reference.

[0070] In addition, compounds of the formula I are, subsequent to their preparation, preferably isolated and purified to obtain a composition containing an amount by weight equal to or greater than 99% formula I compound ("substantially pure" compound I), which is then used or formulated as described herein. Such "substantially pure" compounds of the formula I are also contemplated herein as part of the present invention. [0071] All stereoisomers of the compounds of the instant invention are contemplated, either in admixture or in pure or substantially pure form. The compounds of the present invention can have asymmetric centers at any of the carbon atoms including any one of the R substituents and/or exhibit polymorphism. Consequently, compounds of formula I can exist in enantiomeric, or diastereomeric forms, or in mixtures thereof. The processes for preparation can utilize racemates, enantiomers, or diastereomers as starting materials. When diastereomeric or enantiomeric products are prepared, they can be separated by conventional methods for example, chromatographic or fractional crystallization. [0072] "Stable compound" and "stable structure" are meant to indicate a compound that is sufficiently robust to survive isolation to a useful degree of purity from a reaction mixture, and formulation into an efficacious therapeutic agent. The present invention is intended to embody stable compounds.

[0073] "Therapeutically effective amount" is intended to include an amount of a compound of the present invention alone or an amount of the combination of compounds claimed or an amount of a compound of the present invention in combination with other active ingredients effective to inhibit MIP- lα or effective to treat or prevent inflammatory disorders.

[0074] As used herein, "treating" or "treatment" cover the treatment of a disease- state in a mammal, particularly in a human, and include: (a) preventing the disease- state from occurring in a mammal, in particular, when such mammal is predisposed to the disease-state but has not yet been diagnosed as having it; (b) inhibiting the disease-state, i.e., arresting it development; and/or (c) relieving the disease-state, i.e., causing regression of the disease state.

SYNTHESIS

[0075] Compounds of formula I of may be prepared as shown in the following reaction schemes and description thereof, as well as relevant literature procedures that may be used by one skilled in the art. Exemplary reagents and procedures for these reactions appear hereinafter and in the working examples set forth below.

SCHEME I

[0076] Scheme I describes a method for preparing compounds of formula I. Both, a carbohydrazide intermediate II and a dicarbonyl intermediate III can be obtained commercially, prepared by methods known in the literature or other methods used by one skilled in the art. Formation of compound I can be carried by heating a carbohydrazide intermediate II, a dicarbonyl intermediate III, and an ammonia source, such as ammonium acetate ("NH ₄ OAc"), in a high boling point solvent, such as glacial acetic acid, bromobenzene or xylene. Alternatively, the reaction can be carried out in a microwave reactor. (J. Org. Chem. (2004) 69, pp. 7171-7182. Tetrahedron. Lett. (2003) 44, pp. 1123-1127)

V I

[0077] Scheme II describes a method for preparing an amidrazone intermediate V and compounds of formula I. A nitrile intermediate IV can be obtained commercially, prepared by methods known in the literature or by other methods known to one skilled in the art. Formation of an amidrazone intermediate V can be obtained by treating a nitrile intermediate IV with lithium hydrazide ("NH ₂ NHVn-

BuLi"). Subsequent treatment of amidrazone intermediate V with an appropriate dicarbonyl intermediate III in an appropriate solvent, for example, anhydrous ethanol ("EtOH"), provides compounds of formula I. (J. Org. Chem. 2004, 69, 7171-7182)

ASSAY(S) FOR 11-BETA-HYDROXYSTEROID DEHYDROGENASE

ACTIVITY

[0099] The in vitro inhibition of recombinant human 11-beta-HSDl was determined as follows.

[00100] Recombinant human 11-beta-HSDl was expressed stably in HEK 293 EBNA cells. Cells were grown in DMEM (high glucose) containing MEM non-

essential amino acids, L-glutamine, hygromycine B (200ug/ml), and G418 (200ug/ml). The cell pellets were homogenized, and the microsomal fraction was obtained by differential centrifugation. 11-beta-HSDl over expressed microsomes were used as the enzyme source for the Scintillation Proximity Assay (SPA). The test compounds at the desired concentration were incubated at room temperature with 12.5 μg of microsomal enzyme, 250 nM [ ³ H] -cortisone, 500 μM NADPH, 50 mM MES, pH 6.5, and 5 mM EDTA in 96-well OptiPlates. The reaction was terminated with the addition of 1 mM 18β-glycerrhentic acid. SPA reagent mixture (YSi anti- rabbit IgG, anti-cortisol antibody in 50 mM Tris, pH 8.0 containing 1% CHAPS and 1% glycerol) was added and the reaction was further incubated at room temperature over night and counted in TopCount. The IC50 (concentration of compound required for 50% inhibition of Cortisol formation) was determined using XLfit. [00101] As a means of confirming selectivity for 11-betaHSDl, the compounds of the present invention were also screened for 11 -betaHSD2 activity. The in vitro inhibition of recombinant human 1 l-betaHSD2 was determined as follows:

[00102] Recombinant human 1 l-betaHSD2 was expressed stably in HEK 293 EBNA cells. The microsomal fraction over expressing 1 l-betaHSD2 was prepared from the cell homogenate. The test compounds at the desired concentration were incubated at 37°C with 10 μg of microsomal enzyme, 100 nM-cortisol, 1 mM NAD, and 20 mM Tris, pH 7.5 in 96-well plates for 3h. The reaction was stopped with the addition of equal volume of acetonitrile containing 200 ng/mL triamcinolone (internal standard). The plate was centrifuged and the supernatant was transferred to another 96-well assay plate. Cortisone in the samples was analyzed by LC/MS/MS (Micromass Quattro Ultima Triple Quadrupole Mass Spectrometer). From the MS response (ratio of compound to the internal standard), cortisone formation was calculated using the cortisone standard curve determined on each plate. The IC50 (concentration of compound required for 50% inhibition of cortisone formation) was determined using XLfit. [00103] In general, preferred compounds of the present invention, such as particular compounds disclosed in the following examples, have been identified to inhibit the catalytic activity of 11 -beta-hydroxysteroid dehydrogenase type I at concentrations equivalent to, or more potently than, 10 μM, preferably 5 μM, more

preferably 3 μM, thereby demonstrating compounds of the present invention as especially effective inhibitors of 11 -beta-hydroxysteroid dehydrogenase type I. Potencies can be calculated and expressed as either inhibition constants (Ki values) or as IC50 values, and refer to activity measured employing the assay system described above.
