Prostate cancer is one of the main causes of male cancer-related deaths worldwide and the suppression of androgen receptor signalling is established as an effective strategy for the treatment. A series of galeterone analogues including several steroid-fused azacycles, as well as 17-(benzimidazol-1-ylimino), 16α-(benzimidazol-2-ylamino), and 16α-(benzothiazol-2-ylamino) steroid derivatives, were synthesized and tested against prostate cancer cell lines. Candidate compound 3f was shown to reduce AR-regulated transcription in a dose-dependent manner in nanomolar ranges and suppress expression of AR-regulated proteins Nkx3.1 and PSA in 22Rv1-ARE14 and VCaP cancer cell lines. Flexible docking study revealed similar position of 3f within AR binding site in comparison of galeterone even with stronger binding energy.
