Compounds active at the glucocorticoid receptor

FIELD OF THE INVENTION

[0001] This invention relates to novel compounds that are liver selective glucocorticoid receptor antagonists, to methods of preparing such compounds, and to methods for using such compounds in therapy and in the regulation of metabolism, especially lowering blood glucose levels.

BACKGROUND OF THE INVENTION

[0002] A major problem with both Type 2 and Type 1 diabetes is that there is an excessive and inappropriate production of glucose by the liver. This abnormality is the primary cause of fasting hyperglycemia and occurs in addition to defects in regulation of insulin release and in peripheral sensitivity to insulin. Thus, agents that decrease liver glucose production would be beneficial for treating both Type 2 and also Type 1 diabetes. Intensive treatment of the hyperglycemia of Type 1 diabetes mellitus has been shown to markedly decrease the development of ocular, renal and neuropathic complications, and there is evidence that intensive treatment is also beneficial for Type 2 diabetes. The available data also indicate that most patients are currently not receiving ideal and state-of-the-art treatment for either Type 2 or Type 1 diabetes. This inadequacy exists in spite of the availability of several different types of preparations of insulin for treatment of both Type 2 and Type 1 diabetes, and of a number of additional modalities, including agents that stimulate insulin release (e.g. sulfonylureas), influence liver glucose production (e.g. mefformin), affect the sensitivity to insulin (e.g. compounds interacting with the PPARγ such as troglitazone, rosiglitazone and pioglitazone) and glucose absorption (e.g. α-glucosidase inhibitors such as acarbose). In spite of the availability of several different orally active agents that lower blood glucose levels, many patients with Type 2 diabetes also require insulin for control of their blood sugar levels. Overall, insulin usage in Type 2 diabetes exceeds that for Type 1 diabetes, and there is general agreement that there is a need for additional orally active agents to treat Type 2 diabetes.

[0003] The glucocorticoids secreted from the adrenal gland (dominantly cortisol in humans) were so-named because of their ability to regulate glucose metabolism. These steroids stimulate the production of glucose in the liver by promoting gluconeogenesis, which is the biosynthesis of new glucose (i.e. not glucose from glycogen). Thus, in glucocorticoid insufficiency there is a tendency to hypoglycemia, with decreased liver glucose production. Further, development of Addison's disease in the diabetic generally leads to lowered glucose levels. Conversely, glucocorticoid excess can provoke frank diabetes in individuals with latent diabetes mellitus, and generally aggravates glycemic control in established diabetics. Similar influences have been observed in various animal models.

[0004] The glucocorticoid receptor (GR) belongs to a large group of ligand dependent intracellular receptors, which regulate transcription of genes. The increased glucose production in response to glucocorticoids is due to effects of a number of proteins, which are GR regulated. Important among these proteins are various transaminases that convert amino acids to glucose precursors, glucose-6 phosphatase and phosphoenolpyruvate carboxy-kinase (PEPCK). Even a modest increase of PEPCK, as obtained in transgenic mice, gives rise to hyperglycemia. In mice with Type 2 diabetes and increased levels of corticosterone (the endogenous glucocorticoid of that species) there is increased expression of PEPCK. This over-expression of PEPCK can be repressed by treatment with the GR antagonist RU486 with a concomitant decrease in the hyperglycemia.

[0005] The considerations outlined above indicate that if actions of endogenous glucocorticoids on liver glucose production could be blocked in a specific manner, glycemic control could be improved for the benefit of the diabetic patients. However, to date, all means to block glucocorticoid action have been general. Thus, adrenalectomy leaves the patient with frank adrenal insufficiency and the problems of Addison's disease. Blockade of adrenal steroid production, for example by metyrapone, or of glucocorticoid action, for example with RU486 is ordinarily of limited duration of effectiveness and when it is effective also results in generalized adrenal insufficiency. Longterm, compensatory ACTH hypersecrefion and increased cortisol release that override the block generally overcome these treatments. By contrast, a liver-selective GR antagonist would not have these problems, but should yet counteract the increased liver glucose production in diabetes mellitus and should be useful for treatment of Type 2 diabetes.

[0006] A liver selective GR antagonist offers a number of advantages. First, it would decrease liver glucose production. This action will have a significant effect on glycemic control. In fact, excessive liver glucose production can be the major defect in Type 2 diabetes. Secondly, such a drug should enhance insulin sensitivity because of the overall improvement in the metabolic milieu and the amelioration of the hyperglycemia-induced defects in insulin action and secretion. The decreased demand on β-cell secretion, as a result of a reduction in glycemia, would retard the progressive β-cell dysfunction characteristic of Type 2 diabetes. Another advantage of GR antagonist treatment compared with sulfonylurea or insulin treatment is that the patient would run a lower risk of hypoglycemia.

[0007] Previous efforts to block glucocorticoid action in diabetes have been hampered by the fact that any compounds used would generally block glucocorticoid action in all tissues and would lead to the potential problems of glucocorticoid insufficiency, such as hypotension, shock and ultimately death if the organism is exposed to sufficiently strong stress conditions. In contrast, a liver-selective GR-antagonist with minimal effects outside the liver could be used as a front line therapy for Type 2 diabetes, or could be used in conjunction with other existing therapies.

[0008] Also, glucocorticoids are known to influence the development and/or maintenance of inflammation, autoimmune disease, transplant rejection, neoplasm, leukemia, lymphoma, Cushings disease, adrenal disease, renal disease, cerebrovascular ischemia, hypercalcemia, cerebral edema, thrombocytopenia, inflammatory bowel disease, wound healing, HIV infection, central nervous system disease, spinal cord tumour, glaucoma, sleep disorder, depression, anxiety disorder, atherosclerosis, hypertension, osteoporosis, occular hypertension, nephrotoxicity, infarction, endometriosis, pregnancy disorder, psychosis, Alzheimers disease, cocaine use disorder, asthma, allergic rhinitis, conjuctivitis, rheumatoid arthritis, dermatitis, eczema, osteoarthritis, hypoglycemia, hyperinsulinemia, hyperlipidemia and obesity.

[0165] The compounds of formula I may be prepared by the exemplary processes described in the following reaction schemes. Exemplary reagents and procedures for these reactions appear hereinafter and in the working Examples.

[0166] Compounds of formula I of the invention may be prepared using the sequence of steps outlined in Schemes 1 to 6 set out below. The groups R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, and R11 in Schemes 1 to 6 are as defined in formula I. The groups R1, R2, R3, R4, R5, R6, R7, R8, R9, R10, and R11 may be modified one or several times, after or during the preparation of compounds of formula I by methods known in the art. Examples of such methods include, but are not restricted to, substitutions, reductions, oxidations, alkylations, hydrolysis, esterifications, and etherifications. Y′ is Y, or a group that can be transformed to Y in one or several synthetic steps, after or during the preparation of compounds of formula I, by methods known by a person skilled in the art. Examples of such transformations include, but are not restricted to, demethylation of methyl ethers, alkylations, silylations or acylations of a hydroxy group, hydrolysis of esters, carbamates, or silyl ethers, and transition metal catalyzed alkoxylations or aminations of triflates, chlorides, bromides, iodides, or boronic acids or esters. E is R1, or a group that can be transformed to R1 in one or several synthetic steps after or during the preparation of compounds of formula I, by methods known by a person skilled in the art. Examples of such transformations include, but are not restricted to, nucleophilic substitutions of an alkyl group activated by a halogen or a sulphonic acid ester, hydrolysis of an ester or a nitrile to give a carboxylic acid, or the transformation of a nitrile into an amide or into a tetrazole.

[0167] Scheme 1 describes a synthetic route that begins with a coupling reaction between an appropriately substituted iodonium salt 2 and an appropriately substituted phenol 1 to give the diarylether 3. The coupling is preferably catalyzed by metals, preferably Cu, Ni, Pd, or suitable salts, complexes, oxides or hydroxides thereof in the presence of a base. Suitable bases include, but are not restricted to, triethylamine, pyridine, K2CO3 and Cs2CO3. Alternatives to this ether formation include, but is not restricted to, transition metal catalyzed couplings of phenols with aryl halides or arylboronic acids, or other reactions known by a person skilled in the art. In the next step diarylether 3 is converted to the ketone 4 by introducing R5CO, e.g. by a Friedel-Crafts reaction of diarylether 3 with an appropriate acyl halid, carboxylic acid anhydride, carboxylic acid, or ketene. The reactiQn is preferably performed in the presence of a Lewis or a Brønstedt acid. Suitable acids include, but are not restricted to, H2SO4, polyphosphoric acid, CF3SO3H, TiC4, AlCl3, ZnCl2, BF3OEt2, and the like. Compound 5 is formed by introducing the group R6 into ketone 4 by a reaction with a nucleophile, e.g. a Grignard, organocerium, or an organolithium reagent, or in case R6 is hydrogen, by a reducing agent such as NaBH4, NaBH3CN, or diisobutylaluminium hydride. The hydroxy group of alcohol 5 may then be converted in one ore several synthetic steps to the R7-group in compound 6. Examples of such conversions include, but are not restricted to, alkylations, acylations, halogenations, and reactions with alcohols or phenols in the presence of a Lewis or a Brønstedt acid. Suitable acids include, but are not restricted to H2SO4, polyphosphoric acid, CF3SO3H, TiCl4, AlCl3, BF3.OEt2, SnCl2.H2O, p-toluenesulfonic acid, and the like. If E is not R1 in compound 6, E in compound 6 is transformed to R1 in compound 7. Such transformations may be performed in one or several synthetic steps and include, but are not restricted to, nucleophilic substitutions (e.g. by cyanides) of an alkyl group activated by a halogen or a sulphonic acid ester (e.g. by mesylate, tosylate or triflate), hydrolysis of an ester or a nitrile to give a carboxylic acid, or the transformation of a nitrile into a tetrazole. Alternatively, alcohol 5 can be transformed to compound 8, using the same method as described above for the transformation of compound 6 to compound 7. Compound 8 may then be converted to 7 using the same method as described above for the transformation of alcohol 5 to compound 6. If Y′═Y, compound 7 is equal to compounds of formula I of the present invention, if not, Y′ is converted to Y as described previously.

[0168] Scheme 2 describes an alternative synthesis to the intermediate 3 in Scheme 1. As in Scheme 1, the synthetic route begins with a coupling reaction, in this case between the iodonium salt 9 and the phenol 1 to give the diarylether 10. The coupling is preferably catalyzed by metals, preferably Cu, Ni, Pd, or suitable salts, complexes, oxides or hydroxides thereof in the presence of a base. Suitable bases include, but are not restricted to, triethylamine, pyridine, K2CO3 and Cs2CO3. Alternatives to this ether formation include, but is not restricted to, transition metal catalyzed couplings of phenols with aryl halides or arylboronic acids, or other reactions known by a person skilled in the art. In the next step diarylether 10 is converted to the ketone 11 by introducing RACO, e.g. by a Friedel-Crafts reaction of diarylether 10 with an appropriate acyl halide, carboxylic acid anhydride, carboxylic acid, or ketene. The reaction is preferably performed in the presence of a Lewis or a Brønstedt acid. Suitable acids include, but are not restricted to, H2SO4, polyphosphoric acid, CF3SO3H, TiCl4, AlCl3, ZnCl2, BF3.OEt2, and the like. Compound 11 is converted to compound 12 in one or several synthetic transformations by reactions including, but not restricted to, nucleophilic substitutions, reductions, olefinations, oxidations, alkylations, hydrolysis, esterifications and etherifications. When RA, RB and RC, together with the carbon to which they are bound equal R4, compound 12 is the same as compound 3, that may be transformed to compounds of formula I of the invention by using the synthetic sequences described in Scheme 1. If RA, RB and RC, together with the carbon to which they are bound do not equal R4, they can be converted to R4 by reactions known by a person skilled in the art.

[0169] The RACO-group can also be introduced by a so called Fries rearrangement, as described in Scheme 3. In this case ester 13 (=10, where Y′═RACOO) is converted to phenol 14 (=11, where Y′═OH) in a reaction catalyzed by light or by a Lewis or a Brønstedt acid. Suitable acids include, but are not restricted to, H2SO4, polyphosphoric acid, CF3SO3H, TiC4, AlCl3, ZnCl2, BF3.OEt2, and the like. Compound 13 can be prepared from compounds 9 or 10 by synthetic transformations known to those skilled in the art.

[0170] Scheme 4 describes yet another approach to introduce R4 into the molecule. The diarylether 10 is halogenated to give compound 15 (X=halogen). Suitable halogenating agents include, but are not restricted to iodine, NaI/NaOH, bromine, N-bromosuccinimide and 1,3-dibromo-5,5-dimethylhydantoin. Compound 15 is converted to compound 3 using one or several synthetic transformations. Such synthetic transformations include, but are not restricted to, transition metal catalyzed alkylations, alkenylations, alkynylations, arylatons, carbonylations, alkoxylations, and aminations. Scheme 4 also describes a sequence where the diarylether 10 is nitrated to give compound 15 (X═NO2). The nitro group is then transformed in one or several synthetic steps, including, but not restricted to, reductions, alkylations, acylations, diazotations, halogenations, cyanation, and transition metal catalyzed reactions (as described above) to R4 in compound 3.

[0171] Scheme 5 depicts an alternative route to introduce RW into the molecule when R7 in compounds of formula 1 equals hydrogen. The aldehyde 16 (i.e. 4 where R5═H) is synthesized by formylation of compound 3 by reactions including, but not restricted to, electrophilic substitution reactions. Suitable electrophilic substitution reactions include, but are not restricted to the Vilsmeier reaction (i.e. a combination of an activating agent such as POCl3, COCl2 or (COCl)2 and an amide such as DMF or N-phenyl-N-methylformamide) or the combination of MeOCHCl2 and TiCl4. The R5-group (R5 in alcohol 17 (i.e. 5 where R6═H) is introduced by a reaction of the aldehyde 16 and a nucleophile. Suitable nucleophiles include, but are not restricted to Grignard, organocerium, or organolithium reagents. If E is not R1 in compound 17, it is transformed to R1 in compound 18 by methods described previously. If Y′═Y, compound 18 (i.e. 8 where R6═H) is equal to compounds of formula I of the present invention where R6═OH and R7═H, if not, Y′ is converted to Y as described previously.

[0172] Analogously to the reactions described in Scheme 1, compound 19 (i.e. 7 where R7═H) may be obtained by transforming the hydroxy group in 18 to R6-groups other then hydroxy by synthetic transformations known to those skilled in the art. These synthetic transformations include, but are not restricted to, reactions with acylating or sulfonylating reagents (giving compounds of formula I of the present invention where R6═R5C(Z)O, R8OC(Z)O, R8S(O)nO, (R9)(R10)NC(Z)O, or (R9)(R10)NS(O)2O), and R7═H), and reactions with alcohols, phenols, carboxylic acids, or amides in the presence of a suitable Lewis or Brønstedt acid, (giving compounds of formula I of the present invention where R6═R8C(O)O, or R8C(O)N(R11) and R7═H).

[0173] The hydroxy group in 18 may also be converted to a halogen, using reagents such as HCl, HBr, SOCl2, SOBr2, or CBr4/Ph3P, giving compounds of formula I of the present invention where R6=halogen and R7═H. These halogenated compounds may in turn be transformed to compounds of formula I of the present invention where R6═R8O, R8S, (R9(R10)N, R8C(Z)O, R8C(Z)N(R11), R8OC(Z)N(R11), R8S(O)2N(R11) or (R9)(R10)NS(O)2N(R11), and R7═H, by a reaction with an appropriate nucleophilic reagent such as an alcohol, phenol, thiol, amine, carboxylic acid, amide, carbamate, sulfonamide, or a sulfamide. The reaction may be performed in the presence of a suitable base. Suitable bases include, but are not restricted to, triethylamine, N-ethyldiisopropylamine, K2CO3 and Cs2CO3.

[0174] As described in Scheme 5, an alternative to the synthetic sequences 17″ is the sequence 17″, where the transformation of 17′ equals the transformation of 18′, and the transformation of 20′ equals the transformation of 17′. When Y′═Y, compound 19 is equal to compounds of formula I of the present invention where R7═H, if not, Y′ is converted to Y as described previously.

[0175] Compounds of the formula I, where R7═H, can also be obtained by the route described in Scheme 6. In this route, the R6 substituent is introduced prior to R5. Compound 21 is prepared analogously to compound 4 in Scheme I from compound 3. The substituent R6 is in this case selected from C1-12-alkyl, perfluoro-C1-6-alkyl, C3-8-cycloalkyl, C2-6-alkenyl, and C2-6-alkynyl, and R1 is aryl or heteroaryl. Reduction of the carbonyl group in compound 21, by methods described previously, affords the alcohol 22; which is allowed to react with electrophilic aromatic (e.g. phenols, arylethers, or anilines), or hetero-aromatic compounds (e.g. indoles or pyrroles), in the presence of a suitable Lewis or Brønstedt acid to give 23. When E is R1, and Y′═Y, compound 23 is equal to compounds of formula I of the present invention where R7═H, if not, E is converted to R1, and Y′ is converted to Y as described previously.

[0176] Those skilled in the art will readily understand that known variations of the processes described herein and of the experimental conditions, such as solvents, temperatures and times, of the following preparative procedures, can be used to prepare compounds of the formula I of the present invention.
