VN/124-1 (TOK-001) and analogs as potential agents for prostate cancer therapy, putative metabolites (10, 15 and 18) of compound 5 were rationally designed and synthesized. However, none of these agents were as efficacious as 5 in several in vitro studies. Using western blot analysis, we have generated a preliminary structure-activity relationship (SAR) of 5 and related analogs as androgen receptor ablative

advantageous therapeutic paradigm for the effective treatment of prostate cancer. In continuation of our program to identify and develop improved efficacious novel small-molecule agents designed to disrupt AR signaling through enhanced AR degradation, we have designed, synthesized, and evaluated novel C-3 modified analogues of our phase 3 clinical agent, galeterone (5).

Galeterone and its C-3 analogs are of substantial interest because of their multi-target anticancer activities, including AR and Mnk degrading activities. Provided are novel procedures for gram-scale, high-yield synthesis of C-3 analogs of galeterone, including 3β-(1H-imidazole-1-yl)-17-(1H-benzimidazole-1-yl)-androsta-5,16-diene (galeterone 3β-imidazole) and 3β-(pyridine-4-ylmethoxy)-17-(1H-benzimidazol-1-yl)androsta-5,16-diene (galeterone 3β-pyridine methoxylate).

The present disclosure provides the design and synthesis of novel steroidal compounds that cause down-regulation of the androgen receptor (AR), both full length and splice variant. The compounds are potential agents for the treatment of all forms of prostate cancer and other diseases that depend on functional AR.

Metastatic castration-resistant prostate cancer (mCRPC) with high mortality has seriously threatened men’s health. Bifunctional agents simultaneously degrade and antagonize androgen receptor (AR), display robust AR signaling pathway blockade, and show the therapeutic prospect for mCRPC. Herein, systemic structural modifications on the C-3, C-6, and C-17 positions of galeterone led to the discovery
高死亡率的转移性去势抵抗性前列腺癌(mCRPC)严重威胁男性健康。双功能药物同时降解和拮抗雄激素受体 (AR),显示出强大的 AR 信号通路阻断作用,并显示出 mCRPC 的治疗前景。在此,对galeterone的C-3,C-6和C-17位置的系统结构修饰导致发现具有AR拮抗和降解双重功能的67-b 。在体外,67-b在不同的 PCa 细胞(LNCaP 和 22RV1)中表现出优异的抗增殖活性和有效的 AR 降解活性,以及对野生型和突变体(W741L、T877A 和 F876L)ARs 的出色拮抗活性。体内, 67-b在 Hershberger 试验中有效抑制激素敏感器官的生长,并在恩杂鲁胺抗性(c4-2b-ENZ)异种移植模型中表现出肿瘤消退。这些结果证实67-b是一种有前途的 AR 降解剂和拮抗剂,可用于治疗 mCRPC 患者。
