## Background
PRIORITY TO RELATED APPLICATION(S)
This application claims the benefit of International Patent Application No. PCT/CN2011/083229, filed Nov. 30, 2011, which is hereby incorporated by reference in its entirety.
FIELD OF THE INVENTION
The present invention relates to organic compounds useful for therapy or prophylaxis in a mammal, and in particular to aldosterone synthase (CYP11B2 or CYP11B1) inhibitors for the treatment or prophylaxis of chronic kidney disease, congestive heart failure, hypertension, primary aldosteronism and Cushing syndrome.
BACKGROUND OF THE INVENTION
Herein we describe inhibitors of aldosterone synthase that have the potential to protect from organ/tissue damage caused by an absolute or relative excess of aldosterone. Hypertension affects about 20% of the adult population in developed countries. In persons 60 years and older, this percentage increases to above 60%. Hypertensive subjects display an increased risk of other physiological complications including stroke, myocardial infarction, atrial fibrillation, heart failure, peripheral vascular disease and renal impairment. The renin angiotensin aldosterone system is a pathway that has been linked to hypertension, volume and salt balance and more recently to contribute directly to end organ damage in advanced stages of heart failure or kidney disease. ACE inhibitors and angiotensin receptor blockers (ARBs) are successfully used to improve duration and quality of life of patients. These drugs are not yielding maximum protection. In a relatively large number of patients ACE and ARB's lead to so-called aldosterone breakthrough, a phenomenon where aldosterone levels, after a first initial decline, return to pathological levels. It has been demonstrated that the deleterious consequences of inappropriately increased aldosterone levels (in relation to salt intake/levels) can be minimized by aldosterone blockade with mineralocorticoid receptor antagonists. A direct inhibition of aldosterone synthesis is expected to provide even better protection as it will also reduce non-genomic effects of aldosterone as well.
The effects of aldosterone on Na/K transport lead to increased re-absorption of sodium and water and the secretion of potassium in the kidneys. Overall this results in increased blood volume and, therefore, increased blood pressure. Beyond its role in the regulation of renal sodium re-absorption aldosterone can exert deleterious effects on the kidney, the heart and the vascular system especially in a “high sodium” context. It has been shown that under such conditions aldosterone leads to increased oxidative stress which ultimately may contribute to organ damage. Infusion of aldosterone into renally compromised rats (either by high salt treatment or by unilaterally nephrectomy) induces a wide array of injuries to the kidney including glomerular expansion, podocyte injury, interstitial inflammation, mesangial cell proliferation and fibrosis reflected by proteinuria. More specifically aldosterone was shown to increase the expression of the adhesion molecule ICAM-1 in the kidney. ICAM-1 is critically involved in glomerular inflammation. Similarly, aldosterone was shown to increase the expression of inflammatory cytokines, such as interleukin IL-1b and IL-6, MCP-1 and osteopontin. On a cellular level it was demonstrated that in vascular fibroblasts aldosterone increased the expression of type I collagen mRNA, a mediator of fibrosis. Aldosterone also stimulates type IV collagen accumulation in rat mesangial cells and induces plasminogen activator inhibitor-1 (PAI-1) expression in smooth muscle cells. In summary aldosterone has emerged as a key hormone involved in renal damage. Aldosterone plays an equally important role in mediating cardiovascular risk.
There is ample preclinical evidence that MR-antagonists (spironolactone and eplerenone) improve blood pressure, cardiac and renal function in various pre-clinical models.
More recently preclinical studies highlight the important contribution of CYP11B2 to cardiovascular and renal morbidity and mortality. The CYP11B2 inhibitor FAD286 and the MR antagonist spironolactone were evaluated in a rat model of chronic kidney disease (high angiotensin II exposure; high salt and uni-nephrectomy). Angiotensin II and high salt treatment caused albuminuria, azotemia, renovascular hypertrophy, glomerular injury, increased PAI-1, and osteopontin mRNA expression, as well as tubulointerstitial fibrosis. Both drugs prevented these renal effects and attenuated cardiac and aortic medial hypertrophy. Following 4 weeks of treatment with FAD286, plasma aldosterone was reduced, whereas spironolactone increased aldosterone at 4 and 8 weeks of treatment. Similarly only spironolactone but not FAD286 enhanced angiotensin II and salt-stimulated PAI-1 mRNA expression in the aorta and the heart. In other studies the CYP11B2 inhibitor FAD286 improved blood pressure and cardiovascular function and structure in rats with experimental heart failure. In the same studies FAD286 was shown to improve kidney function and morphology.
Administration of an orally active CYP11B2 inhibitor, LCI699, to patients with primary aldosteronism, lead to the conclusion that it effectively inhibits CYP11B2 in patients with primary aldosteronism resulting in significantly lower circulating aldosterone levels and that it corrected the hypokalemia and mildly decreased blood pressure. The effects on the glucocorticoid axis were consistent with a poor selectivity of the compound and a latent inhibition of cortisol synthesis. Taken together these data support the concept that a CYP11B2 inhibitor can lower inappropriately high aldosterone levels. Achieving good selectivity against CYP11B1 is important to be free of undesired side effects on the HPA axis and will differentiate different CYP11B2 inhibitors.

Halogen or triflate substituted heterocyclic compounds 2 react with aryl lactams 1 in solvents like 1,4-dioxane, in the presence of copper (I) iodide, potassium or cesium carbonate, a chelating 1,2-diamino compound like N,N′-dimethylethylenediamine or trans-1,2-diamino-hexane, at elevated temperatures, preferable with the aid of microwave heating to form lactam substituted heterocyclic compounds 3 (step a) as described in Scheme 1.




Treatment of heteroaryl linked alcohol compounds 51 (Scheme 2b) with a base like sodium hydride in a solvent like THF or DMF and subsequently with a suitable alkylating agent such as a halide, mesylate or tosylate preferably between RT and the reflux temperature of the solvent gives compounds 52 (step a). Alternatively (Scheme 2a), heteroaryl linked alcohol compounds 51 can e.g. be converted into the corresponding chlorides by treatment with thionyl chloride in a solvent like dichloromethane preferably between 0° C. and room temperature (step b). Said heteroaryl linked chlorides, compounds 53, react with nucleophilic amino-moieties 54a or aryl, heteroaryl or heterocycloalkyl compounds 54b per se or after anion formation e.g. with sodium hydride in solvents like N,N′-dimethylformamide in a temperature range between 0° C. and about 100° C. to form adducts 55a or 55b (step c).








Alternatively (Scheme 2c), heteroaryl linked chloride compounds 53 react with boronic acids or esters 56 i) by using Suzuki conditions, e.g. in the presence of catalysts, such as tri-o-tolylphosphine/palladium(II)acetate, tetrakis-(triphenylphosphine)-palladium, bis(triphenylphosphine)palladium(II)chloride or dichloro[1,1′-bis(diphenylphosphino)-ferrocene]palladium(II) optionally in the form of a dichloromethane complex (1:1), and in the presence of a base, such as aqueous or non-aqueous potassium phosphate, sodium or potassium carbonate, in a solvent, such as dimethylsulfoxide, toluene, ethanol, dioxane, tetrahydrofuran or N,N-dimethylformamide, and in an inert atmosphere such as argon or nitrogen, in a temperature range preferably between room temperature and about 130° C. or ii) by using a nickel (0) catalyst, e.g. bis(1,5-cyclooctadiene)nickel (0) in the presence potassium phosphate, bis(1-methyl-1H-imidazol-2-yl)methane in N,N-dimethyl acetamide at temperatures around 100° C. giving adducts 57 (steps d).




Aldehydes or ketones 58 (Scheme 2d) can be treated with suitable amino-moieties 59 the presence of NaBH(OAc)3 in a one-step procedure in a solvent like methanol preferably around room temperature or in a two-step procedure by first treatment with titanium (IV) isopropoxide in solvents like methanol or toluene preferably at temperatures between room temperature and the reflux temperature of the solvents followed by reaction with NaBH4 preferably between 0° C. and room temperature which converts aldehydes or ketones 58 into amino compounds 60; alternatively imines obtained after treatment with titanium (IV) isopropoxide can be evaporated, then be re-dissolved in a solvent like THF and being treated with a Grignard reagent R20MgX, preferably between −40° C. and 0° C. leading to amino compounds 60 carrying the specific R20 substituent (step e).




Heteroaryl halides 101 (Scheme 2e) react with boronic acids or esters 102 using Suzuki conditions as described above to give adducts 103 (step a). Phenols 104 react with alcohols 105 under Mitsunobu conditions e.g. with triphenylphosphine and di-tert-butyl-, diisopropyl-, diethyl-azodicarboxylate or di-(4-chlorobenzyl)azodicarboxylate as reagents in solvents like toluene, dichloromethane or tetrahydrofuran preferably at ambient temperature to give adducts 106 (step b). Compounds 106 can be transformed by additional standard modifications into synthons 107 (step c).




Carbamates 201 (Scheme 3) react with polyphosphoric acid at elevated temperature (e.g. 100-180° C.) to form 3,4-dihydro-2H-isoquinolin-1-one derivatives 202 (step a). Trifluoroacetamides 203 can be cyclized to 1-(3,4-dihydro-1H-isoquinolin-2-yl)-2,2,2-trifluoro-ethanone compounds 204 by treatment with paraformaldehyde in a mixture of concentrated sulfuric acid and acetic acid preferably around room temperature (step b). Removal of the trifluoroacetyl group by treatment with e.g. potassium hydroxide in a solvent like ethanol at temperatures around room temperature gives tetrahydro-isoquinoline compounds 205 (step c). Oxidation of tetrahydro-isoquinoline compounds 205 e.g. with iodoso benzene and potassium bromide preferably in water gives 3,4-dihydro-2H-isoquinolin-1-one compounds 202 (step d). Reaction of isoindole-1,3-dione compounds 206 with a Grignard reagent R1MgX in a solvent like THF preferably around 0° C. gives adducts 207 (step e). Subsequent treatment with triethylsilane and trifluoroboron etherate in a solvent like dichloromethane and in a temperature range preferably between −25° C. and RT gives isoindolone compounds 208 (step 0. Introduction a methoxybenzyl protecting group into isoindolone compounds 209 (e.g. by treatment with sodium bis(trimethylsilyl) amide and 1-bromomethyl-4-methoxy-benzene in THF between 0° C. and RT) gives protected compounds 210 (step g); similarly, a methoxybenzyl protecting group can be introducted into compounds 208. Treatment of compounds 208 carrying an additional methoxybenzyl protecting group or compounds 210 with a base like sodium hydride in a solvent like THF and then with an alkyl halide, mesylate or tosylate preferably between RT and the reflux temperature of the solvent gives compounds 211 with structurally different or structurally identical R1 and R2 groups (step h). Alternatively, treatment of compounds 208 carrying an additional methoxybenzyl protecting group or compounds 210 with a base like NaH, LDA or LiHMDS in solvents like DMF, tetrahydrofuran or 1,2-dimethoxyethane and then with one or sequentially with two different alkyl halides, mesylates or tosylates preferably between −78° C. and the reflux temperature of the solvent gives compounds 211 with structurally different or structurally identical R1 and R2 groups (step h). Removal of the protecting group, e.g. by treatment with trifluoroacetic acid at elevated temperature gives isoindolone compounds 212 (step i). Treatment of compounds 210 with a base like sodium hydride in a solvent like THF and then with an alpha, omega di-haloalkane or di-haloheteroalkane like e.g. 1,2-dibromoethane, preferably between RT and the reflux temperature of the solvent gives spiro compounds 213 (step k) and after subsequent removal of the protecting group, spiro compounds 214 (step 1).




5-Halo-nicotinic acid or pyridazine carboxylic acid compounds 301 or 305 (Scheme 4a) react with acrylic acid ester compounds 302 after deprotonation with base like LDA or LiHMDS in solvents like THF preferably around −78° C. giving cyclic beta keto ester compounds 303 and 306 (step a). Ester compounds 303 or 306 with R111=H can be treated with a base like NaH, LDA or LiHMDS in solvents like DMF, tetrahydrofuran or 1,2-dimethoxyethane, followed by addition of an alkyl or cycloalkyl halide, mesylate or tosylate, or e.g. a N-halobenzensulfonamide, a reaction preferably performed between −78° C. and room temperature, to give ester compounds 303 or 306 carrying a substituent R111 different from H. Treatment of beta keto-ester compounds 303 or 306 with aqueous acid preferably at reflux induces ester hydrolysis and subsequent decarboxylation providing ketones 304 and 307 (step b). Ketones 304 and 307 with R111=H and R113=H can be treated with a base like NaH, LDA or LiHMDS in solvents like DMF, tetrahydrofuran or 1,2-dimethoxyethane, followed by addition of one or subsequently two different alkyl or cycloalkyl halides, mesylates or tosylates, or e.g. N-halobenzensulfonamides, a reaction preferably performed between −78° C. and room temperature, to give ketones 304 and 307 carrying at least one of the substituents R111 or R113 different from H. Optionally, ketones 304 and 307 can be converted into the corresponding imines (e.g. with N-butylamine by using a catalyst like toluene sulfonic acid or pyridinum p-toluenesulfonate in a solvent like ethanol preferably at reflux); such imines with R111=H can be reacted with e.g. N-fluorobenzenesulfonimide using K2CO3 or triethyamine as base in solvents like DMF or acetonitrile or mixtures thereof, in the presence of molecular sieves preferably at room temperature to give imines carrying fluoro substituents and after imine hydrolysis (e.g. with hydrochloric acid in acetonitrile) ketones 304 and 307 with R111=F. Ketones 304 and 307, can function as compounds 2 (scheme 1) or can be converted into different compounds 2 (Scheme 1) by further structural modification using methods well known in the art as e.g. reduction of the keto function to a secondary hydroxy group with a reagent like sodium borohydride in methanol or reduction of the keto group to a primary or secondary amino function by reductive amination e.g. by reacting with an amine and NaBH(OAc)3 in methanol.




Dihalopyridine or pyridazine compounds 351 (Scheme 4b) react with bromo-tetramethyl-azadisilolidine reagents 352 after deprotonation with lithium diisopropyl amide in solvents like tetrahydrofuran between −78° C. and 0° C. to give aminoalkyl substituted pyridines or pyridazine 353 (step a). After attachment of a protecting group onto compounds 353 (e.g. by introducing a BOC- or a SES-protecting group by reaction with BOC2O or 2-trimethylsilanyl-ethanesulfonyl chloride, triethylamine, DMF around 0° C.), treatment of amino protected pyridine or pyridazine compounds 354 with a base like potassium carbonate, in a solvent like toluene, and in the presence of a catalyst like tetrakis-(triphenylphosphine)-palladium at temperatures around 100° C. gives bicyclic compounds 355, still carrying a protecting group (step b, c). Standard BOC removal or use of tetrabutylammonium fluoride hydrate, acetonitrile preferably between room temperature and the reflux temperature of acetonitrile then gives bicyclic compounds 356 (step d). Amino compounds 356 can function as compounds 2 (Scheme 1) either as such or after further structural modification by methods well known in the art.




5-Halo-nicotinic acid compounds 305 (Scheme 4c) react with alkene compounds 400 after deprotonation with a base like LDA or LiHMDS in solvents like THF preferably around −78° C. giving alkenes 401 (step a). Diester compounds 402 can be synthesized by methods known to persons skilled in the art such as e.g. by ozonolysis of alkenes 401 in the presence of methanolic NaOH to give compounds 402 which can be cyclized using Dieckmann condensation conditions to give beta keto-ester compounds 403 (step b, c). Treatment of beta keto-ester compounds 403 with aqueous acid preferably at reflux temperature induces ester hydrolysis and subsequent decarboxylation providing ketones 404 (step e). Ester compounds 403 (R111 is H) can be treated with a base like NaH, LDA or LiHMDS in solvents like DMF, tetrahydrofuran or 1,2-dimethoxyethane, followed by addition of an alkyl or cycloalkyl halide, mesylate or tosylate, or e.g. a N-halobenzensulfonamide, a reaction preferably performed between −78° C. and room temperature, to give ester compounds 403 carrying a substituent R111 different from H (step d). Hydrolyses and decarboxylation as described above gives ketones 404 (step e). Ketone compounds 404 can function as compounds 2 (Scheme 1) either as such or after further structural modification by methods described herein or by methods well known in the art.

Assay Procedures
Herein we identified the use of the G-402 cell line as a host cell to ectopically express (transiently or stably) enzymes of the CYP11 family. Specifically we developed stable G-402 cells expressing ectopically human CYP11B1, human CYP11B2, human CYP11A1, cynmolgus CYP11B1 or cynomolgus CYP11B2 enzyme activity. Importantly the identified cell line G-402 expresses co-factors (adrenodoxin and adrenodoxin reductase) important for the activity of the CYP11 family and no relevant enzyme activity of the CYP11 family (in comparison to H295R cells) was detected in these cells. Therefore the G-402 cell line is uniquely suited as a host cell for the ectopic expression of enzymes from the CYP11 family.
G-402 cells can be obtained from ATCC(CRL-1440) and were originally derived from a renal leiomyoblastoma.
The expression plasmids contain the ORF for either human/cyno CYP11B1 or CYP11B2 under the control of a suitable promoter (CMV-promoter) and a suitable resistance marker (neomycin). Using standard techniques the expression plasmid is transfected into G-402 cells and these cells are then selected for expressing the given resistance markers. Individual cell-clones are then selected and assessed for displaying the desired enzymatic activity using 11-Deoxycorticosterone (Cyp11B2) or 11-Deoxycortisol (Cyp11B1) as a substrate.
G-402 cells expressing CYP11 constructs were established as described above and maintained in McCoy's 5a Medium Modified, ATCC Catalog No. 30-2007 containing 10% FCS and 400 μg/ml G418 (Geneticin) at 37° C. under an atmosphere of 5% CO2/95% air.
Cellular enzyme assays were performed in DMEM/F12 medium containing 2.5% charcoal treated FCS and appropriate concentration of substrate (0.3-10 uM 11-Deoxycorticosterone, 11-Deoxycortisol or Corticosterone). For assaying enzymatic activity, cells were plated onto 96 well plates and incubated for 16 h. An aliquot of the supernatant is then transferred and analyzed for the concentration of the expected product (Aldosterone for CYP11B2; Cortisol for CYP11B1). The concentrations of these steroids can be determined using HTRF assays from CisBio analyzing either Aldosterone or Cortisol.
Inhibition of the release of produced steroids can be used as a measure of the respective enzyme inhibition by test compounds added during the cellular enzyme assay. The dose dependent inhibition of enzymatic activity by a compound is calculated by means of plotting added inhibitor concentrations (x-axes) vs. measured steroid/product level (y-axes). The inhibition is then calculated by fitting the following 4-parameter sigmoidal function (Morgan-Mercer-Flodin (MMF) model) to the raw data points using the least squares method:




  y
  =
  
    
      AB
      +
      
        Cx
        D
      
    
    
      B
      +
      
        x
        D
      
    
  




wherein, A is the maximum y value, B is the EC50 factor determined using XLFit, C is the minimum y value and D is the slope value.

The maximum value A corresponds to the amount of steroid produced in the absence of an inhibitor, the value C corresponds to the amount of steroid detected when the enzyme is fully inhibited.
EC50 values for compounds claimed herein were tested with the G402-based assay system described. Cyp11B2 enzyme activity was tested in presence of 1 μM Deoxycorticosterone and variable amounts of inhibitors; Cyp11B1 enzyme activity was tested in presence of 1 μM Deoxycortisol and variable amounts of inhibitors.

To a solution of 6-chloro-2-(5-hydroxymethyl-pyridin-3-yl)-3,4-dihydro-2H-isoquinolin-1-one (example 3) (28.8 mg, 0.1 mmol) in THF (5 mL) was added NaH (8 mg, 0.2 mmol, 60% dispersion in mineral oil) at room temperature. After hydrogen evolution ceased, a solution of methyliodide (0.2 mmol) in THF (5 mL) was added dropwise, and the resulting mixture was stirred at room temperature for 1 hour. The mixture was then treated with satd. aqueous NH4Cl solution and extracted three times with EtOAc. The combined organic layer was washed with water and brine, dried over anhy. Na2SO4 and concentrated in vacuo. The crude product was purified by prep-HPLC to give the title compound (4.5 mg, 14.8%) as a white solid. MS: (M+H)+ 303.1

To a solution of 2-(8-amino-5,6,7,8-tetrahydro-isoquinolin-4-yl)-5-chloro-3-ethyl-2,3-dihydro-isoindol-1-one (511.5 mg, 1.5 mmol) in DCM (15 mL) was added Et3N (3 mmol) and methanesulfonyl chloride (228 mg, 2 mmol) at 0° C. The resulting reaction mixture was stirred at room temperature for 1 hour before it was poured into 1 N HCl in dioxane (15 mL) and washed with EtOAc (15 mL×2). After the organic layer was decanted, the aqueous layer was basified to pH>8 with satd. aq. NaHCO3 solution. After extracted with EtOAc (20 mL×2), the combined organic layers were washed with brine, dried over anhy. Na2SO4, filtered and concentrated in vacuo to give the title compound (228 mg, 62%) as a mixture of four diastereomers. MS: 420.1 (M+H+).
This mixture of diasteromers were then subject to SFC separation (IC 250 mm×50 mm, 5 um, mobile phase A: supercritical CO2, B: IPA (0.05% NH3H2O), A:B=60:40 at 140 mL/min) to give four individual diasteromers (examples 347, 348, 349 and 350). MS: 420.1 (M+H+).
