AI Technical Summary

Benefits of technology

These compounds effectively modulate androgen receptor activity, providing therapeutic benefits for muscle strength, bone density, and age-related conditions like sarcopenia with reduced side effects on other tissues.

Problems solved by technology

However, the effectiveness of known modulators of steroid receptors is often tempered by their undesired side-effect profile, particularly during long-term administration.
For example, the administration of synthetic androgens has been associated with liver damage, prostate cancer, adverse effects on male sexual function and adverse effects associated with cardiovascular and erythropoietic function.

example 1

1-(4-Cyano-2-ethyl-3-(trifluoromethyl)phenyl-1-carbamoyl)-3-hydroxy-pyrrolidine-2-carboxylic acid methyl ester

[0155]

Step 1. N-(4-Chloro-3-trifluoromethylphenyl)-2,2-dimethylpropionamide

[0156]

[0157] To a solution of 15.0 g (76.7 mmol) of 4-chloro-3-(trifluoromethyl)aniline in 200 mL of anhydrous THF cooled to 0-5° C. was added 11.7 mL (84.4 mmol) of NEt3 followed by 10.4 mL (84.4 mmol) of pivaloyl chloride over 30 min. The ice bath was removed, and the mixture was stirred for 1 h, then diluted with ether and filtered. The filtrate was washed with water (2×) and brine, dried (MgSO4), filtered and concentrated. The residue was triturated with hexanes and the solid filtered and dried to give 20.4 g (95%) of the Step 1 compound. 1H NMR (DMSO-d6) δ 1.22 (s, 9H), 7.63 (d, J=8.8, 1H), 8.00 (dd, J=2.8, 8.8, 1H), 8.24 (d, J=2.2, 1H), 9.62 (s, 1H); 13C NMR (DMSO-d6)δ26.94, 118.6, 121.7, 123.6, 124.6, 126.4, 126.6, 131.7, 138.9, 177.1; HPLC-1: 3.62 min retention time, column: Phenominex ODS C...

example 2

1-(4-Cyanonaphthalen-1-ylcarbamoyl)-3-hydroxy-pyrrolidine-2-carboxylic acid methyl ester

[0166]

Step 1. 4-Isocyanato-naphthalene-1-carbonitrile

[0167]

[0168] The title compound was prepared from 4-cyanonaphthylamine in a similar fashion to that described in Step 5 of Example 1 for the preparation of an aryl isocyanate from an aryl amine.

Step 2. 1-(4-Cyanonaphthalen-1-ylcarbamoyl)-3-hydroxypyrrolidine-2-carboxylic acid methyl ester

[0169] To a suspension of the Step 1 compound (0.51 g, 1.96 mmol) in CH2Cl2 (2 mL) cooled to 0° C. was added i-Pr2EtN (0.37 mL, 2.16 mmol). After stirring at 0° C. for 20 min, cis-3-hydroxyproline methyl ester (0.34 g, 1.75 mmol) in CH2Cl2 (1 mL) solution was added, along with 4 Å molecular sieves (0.5 g) and the resulting mixture stirred at rt until urea formation was complete (˜1 h). The reaction mixture was then loaded on a silica gel column, eluted with 50% EtOAc / hexane, and 5% MeOH in EtOAc / hexane (1:1) to afford 436 mg of the title compound as a white...

example 3

1-(5-Chloro-6-cyano-pyridin-3-ylcarbamoyl)-3-hydroxypyrrolidine-2-carboxylic acid methyl ester

[0170]

Step 1. 5-Amino-3-chloropyridine-2-carbonitrile

[0171]

[0172] To a solution of 3-chloro-5-nitro-pyridine-2-carbonitrile (0.1 g, 0.549 mmol) in 50% EtOAc and 40% H2O and 10% HOAc was added iron powder (0.1 g). The reaction mixture was stirred at 60° C. for 5 min until the amine was formed. The mixture was washed with H2O and the EtOAc was removed under reduced pressure. The crude product was purified by chromatography, eluted with 30% EtOAc in hexane and 2% MeOH in EtOAc / hexane to afford the title compound (0.66 g) as a white solid.

Step 2. 3-Chloro-5-isocyanatopyridine-2-carbonitrile

[0173]

[0174] To a stirring suspension of the Step 1 compound (0.066 g, 0.43 mmol) and Et3N (0.09 mL, 0.86 mmol) in THF (4 mL) cooled to 0° C. was added a solution of phosgene (20%) in toluene (0.085 mL, 0.86 mmol). After addition, the mixture was stirred at rt for 10 min. The mixture was then concentrated...

Abstract

There are provided nuclear hormone receptor modulating compounds of formula I wherein R1, R2, R3, X, Y, n and G are as described herein. Further provided are methods of using such compounds for the treatment of nuclear hormone receptor-associated conditions, such as age related diseases, for example sarcopenia, and also provided are pharmaceutical compositions containing such compounds. Other embodiments are also disclosed.

Description

RELATED APPLICATIONS [0001] This application is a divisional of U.S. application Ser. No. 10 / 712,456, filed Nov. 13, 2003, and thus claims priority benefit under 35 U.S.C. § 119(e) of U.S. provisional Application No. 60 / 426,694, filed Nov. 15, 2002, the contents of which are herein incorporated by reference.FIELD OF THE INVENTION [0002] The present invention relates to open chain prolyl urea and thiourea related compounds, methods of using such compounds in the treatment of androgen receptor-associated conditions, such as age-related diseases, for example sarcopenia, and to pharmaceutical compositions containing such compounds. BACKGROUND OF THE INVENTION [0003] Nuclear hormone receptors (NHR's) constitute a large super-family of structurally-related and sequence-specific gene regulators scientists have named “ligand-dependent transcription factors.” R. M. Evans, Science, 240:889 (1988). The steroid binding NHR's (SB-NHR's) form a recognized subset of the NHR's, including the proges...
