(S,R,S)-AHPC-Me dihydrochloride, also known as VHL ligand 2 dihydrochloride, is a chemical compound utilized in the synthesis of ARV-771. ARV-771, a BET PROTAC degrader relying on von Hippel-Landau (VHL) E3 ligase, demonstrates potent degradation of BET protein in castration-resistant prostate cancer (CRPC) cells, with a DC50 of less than 1 nM. This compound serves as the VHL ligand, specifically the (S,R,S)-AHPC-based VHL ligand, that facilitates the recruitment of von Hippel-Lindau (VHL) protein.
EC1169 is a targeted tubulysin conjugate that utilizes EC1167 as its linker. This compound shows promise in the treatment of recurrent metastatic, castration-resistant prostate cancer (MCRPC)[1].
JJ-450 是非竞争性拮抗剂,靶向雄激素受体 (AR),可以抑制野生型 AR 和 突变型 ARF876L 的转录活性。在 PC3 细胞中,JJ-450 抑制 AR 转录活性的 IC50 约为 1-10 μM,具有对 AR 的选择性结合特性,不与雄激素竞争 AR 的配体结合域 (LBD)。JJ-450 通过抑制 AR 的核转运并促使未结合配体的 AR 在细胞核内降解,影响 AR 及其剪切变体(如 ARF876L)的转录活性。该化合物可用于研究 Enzalutamide (MDV3100) 耐药的去势抵抗性前列腺癌 (CRPC)。
