HPOB 是一种高选择性HDAC6抑制剂，IC50为 56 nM，其选择性是其他 HDAC 的 30 倍以上。它提高 DNA 损伤抗癌药物在转化细胞中的有效性。 修改 分子式下标C17H18N2O4 Information HPOB is a potent, selectiveHDAC6inhibitor withIC50of 56 nM, >30-fold selectivity over other HDACs. Targets HDAC6 ; HDAC3 ; HDAC8 ; HDAC1 ; HDAC10 14965,56 nM; 1.7 μM; 2.8 μM; 2.9 μM; 3.0 μM In vitro In normal (HFS) and transformed (LNCaP, A549, and U87) cells, HPOB induces acetylation of α-tubulin, however, not histones, and inhibits cell growth, however, not viability. In HFS cells, HPOB enhances transformed cell death induced by etoposide, doxorubicin, or SAHA. HPOB also enhancing etoposide-induced transformed cell death via the apoptotic pathway in transformed cells. In vivo In mice bearing CWR22 human prostate cancer xenografts, HPOB (300 mg/kg/d i.p.), when in combination with SAHA, causes suppression of the growth of established tumors, while produces no significant suppression when used alone.
