  Design, synthesis, and biological evaluation of 4-arylmethyl-1-phenylpyrazole and 4-aryloxy-1-phenylpyrazole derivatives as novel androgen receptor antagonists

  摘要：

  A series of 4-arylmethyl-1-phenylpyrazole and 4-aryloxy-1-phenylpyrazole compounds B were designed, synthesized, and evaluated for their potential as new-generation androgen receptor (AR) antagonists therapeutically effective against castration-resistant prostate cancer (CRPC). Introduction of a bulky amide substituent (R-2) to the terminal aryl ring of the 4-arylmethyl group favored the reduction of agonistic activity and improved the pharmacokinetic (PK) properties. Similarly, introduction of a bulky substituent in the 4-aryloxy derivatives also resulted in improved PK properties. Compounds 28h and 44b exhibited potent antitumor effects against a CRPC model of LNCaP-hr cell line in a mouse xenograft model. On the contrary, bicalutamide showed only partial suppression of tumor growth. These results suggest that the novel pyrazole derivatives are new-generation AR antagonists, different from the 'first-generation' antagonists such as bicalutamide in a CRPC treatment model.
