  We report herein the discovery of highly potent PROTAC degraders of androgen receptor (AR), as exemplified by compound 34 (ARD-69). ARD-69 induces degradation of AR protein in AR-positive prostate cancer cell lines in a dose- and time-dependent manner. ARD-69 achieves DC50 values of 0.86, 0.76, and 10.4 nM in LNCaP, VCaP, and 22Rv1 AR+ prostate cancer cell lines, respectively. ARD-69 is capable of reducing

  我们在此报告了雄激素受体 (AR) 的高效 PROTAC 降解剂的发现，例如化合物34 (ARD-69)。ARD-69 在 AR 阳性前列腺癌细胞系中以剂量和时间依赖性方式诱导 AR 蛋白降解。ARD-69 达到 DC 50在 LNCaP、VCaP 和 22Rv1 AR+ 前列腺癌细胞系中的值分别为 0.86、0.76 和 10.4 nM。ARD-69 能够将这些前列腺癌细胞系中的 AR 蛋白水平降低 >95%，并有效抑制 AR 调节的基因表达。ARD-69 有效抑制这些 AR 阳性前列腺癌细胞系中的细胞生长，并且比 AR 拮抗剂强 100 倍以上。单剂量的 ARD-69 可有效降低小鼠异种移植肿瘤组织中 AR 蛋白的水平。进一步优化 ARD-69 可能最终导致一种新的治疗 AR+、去势抵抗性前列腺癌的方法。
