Structure–activity relationships of bioisosteric replacement of the carboxylic acid in novel androgen receptor pure antagonists
摘要:
A series of 5,5-dimethylthiohydantoin derivatives were synthesized and evaluated for androgen receptor pure antagonistic activities for the treatment of hormone refractory prostate cancer. CH4933468 (32d) with a sulfonamide side chain not only exhibited antagonistic activity with no agonistic activity in the reporter gene assay but also inhibited the growth of bicalutamide-resistant cell lines. This compound also inhibited tumor growth of the LNCaP xenograft in mice dose-dependently. (c) 2010 Elsevier Ltd. All rights reserved.
Compounds represented by the general formula (I); and drugs and medicinal compositions, containing the compounds: (I) wherein n is an integer of 1 to 20; Q is (II) or (III) A is cyano or the like; B is hydrogen, halogeno, or the like; X1 and X2 are each independently selected from between O and S; E is C1-4 alkyl; and R1, R2, R3 and R4 are each independently selected from between hydrogen and C1-6 alkyl.
