(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)。
Histone H3K27Me1 (23-34) is a peptide fragment of histone H3 that corresponds to amino acid residues 24-35 of the human histone H3.1 and H3.2 sequences. Monomethylation of histone H3 at lysine 27 is associated with actively transcribed genes and positively correlates with H3K36 trimethylation. Levels of H3K27Me1 are increased in tumor tissue isolated from patients with metastatic hormone-na ve and castration-resistant prostate cancer. Histone H3K27Me1 (23-34) has been used in epitope mapping of the lupus-derived monoclonal antibody BT164.
Thailanstatin D, an analogue of Thailanstatin A, inhibits AR-V7 gene splicing by disrupting the interaction between U2AF65 and SAP155, hindering their binding to the polypyrimidine tract situated between the branch point and the 3' splice site. This compound displays potent tumor inhibitory properties in human castration-resistant prostate cancer (CRPC) xenografts, resulting in cellular apoptosis.
