  4-(Anilino)pyrrole-2-carboxamides: Novel non-steroidal/non-anilide type androgen antagonists effective upon human prostate tumor LNCaP cells with mutated nuclear androgen receptor

  摘要：

  Various 4-(anilino)pyrrole-2-carboxamides were designed and synthesized as novel androgen receptor (AR) antagonists without steroidal or anilide structure, based on our strategy for developing full antagonists of nuclear receptors. Introduction of a bulky N-alkyl group, such as a cyclohexylmethyl or benzyl group, increased the binding affinity for wild-type AR and the potency for growth inhibition of androgen-dependent SC-3 cells. Among the compounds obtained, N-[4-[(benzyl)(4-nitrophenyl)amino]-1-methylpyrrole-2-carbonyl]pyrrolidine (22) is as potent an AR antagonist as the typical anilide-type AR antagonists hydroxyflutamide and bicalutamide. Further, compound 22 had potent binding affinity for T877A mutated AR, and dose-dependently inhibited the testosterone-induced production of prostate-specific antigen in LNCaP cells bearing T877A AR.

  Novel non-steroidal/non-anilide type androgen antagonists: discovery of 4-substituted pyrrole-2-carboxamides as a new scaffold for androgen receptor ligands

  摘要：

  We designed and synthesized novel pyrrole-2-carboxamide derivatives as androgen antagonists. Compounds 10 and 13 bearing benzylamine or aniline at the 4-position of the pyrrole ring showed moderate androgen antagonistic activity, and inhibited the androgen-dependent growth of Shionogi carcinoma cells (SC-3). Study of the structure-activity relationships of compound 13 led to a potent androgen antagonist 36, which has higher affinity than flutamide (4) for androgen nuclear receptor (AR). Thus, pyrrole-2-carboxamide is a new scaffold for developing AR antagonists. (c) 2005 Elsevier Ltd. All rights reserved.
