HDAC1-IN-5 是一种有效的HDAC1抑制剂,对 HDAC1 和HDAC6 的IC50分别为 15 nM 和 20 nM。HDAC1-IN-5 可增强癌细胞中组蛋白 H3 和 α-微管蛋白 (α-tubulin) 的乙酰化,促进caspase 3的活化,从而诱导细胞凋亡 (apoptosis)。HDAC1-IN-5 通过与 DNA 结合诱导染色质损伤。HDAC1-IN-5 在异种移植瘤小鼠中表现出较强的肿瘤生长抑制活性。
生物活性 | HDAC1-IN-5 is a potentHDAC1inhibitor withIC50values of 15 nM and 20 nM forHDAC1andHDAC6, respectively. HDAC1-IN-5 can enhance the acetylation ofhistone H3andα-tubulin, as well as promote the activation ofcaspase 3incancercells, thereby inducingapoptosis. HDAC1-IN-5 induces chromatin damage by binding with DNA. HDAC1-IN-5 has strong inhibitory activity against tumor growth in xenograft mice[1]. |
IC50& Target[1] | HDAC1 15 nM (IC50) | HDAC6 20 nM (IC50) |

体外研究 (In Vitro) | HDAC1-IN-5 (compound 4j) (0-50 μM; 48 h) exhibits strong inhibitory effects on HCT116, HeLa, HepG2, MC38, K562 and HEL[1]. HDAC1-IN-5 (0.16-1.5 μM; 48 h) induces apoptosis in a dose-dependent manner[1]. HDAC1-IN-5 (0.17-1.5 μM; 24 h or 48 h) induces downregulation of SPT16 and SSRP-1, induces the cleavage of caspase-3, and increases the expression of Acetyl-Histone H3 and Acetyl-α-tubulin[1].
