Tubulin/HDAC-IN-1 是一种双重的tubulin和HDAC-IN-1抑制剂,其通过与 tubulin 的 CH/π 相互作用以及与 HDAC8 的氢键相互作用而发挥功能。Tubulin/HDAC-IN-1 可抑制 tubulin 聚合并选择性抑制 HDAC8 (IC50: 150 nM)。Tubulin/HDAC-IN-1 对各种人类癌细胞具有细胞毒性,还可将细胞周期阻滞在 G2/M 期并诱导细胞凋亡 (apoptosis)。Tubulin/HDAC-IN-1 可用于神经母细胞瘤、白血病等血液肿瘤和实体肿瘤的研究。
生物活性 | Tubulin/HDAC-IN-1 is a dualtubulinandHDAC-IN-1inhibitor through CH/π interaction with tubulin and hydrogen bond interaction withHDAC8. Tubulin/HDAC-IN-1 inhibits tubulin polymerization and selectively inhibitsHDAC8(IC50: 150 nM). Tubulin/HDAC-IN-1 has cytotoxicity against various humancancercells, also arrests cell cycle in the G2/M phase and induces cellapoptosis. Tubulin/HDAC-IN-1 can be used in the research of hematologic and solid tumors such as neuroblastoma, leukemia[1]. |
IC50& Target[1] | HDAC8 150 nM (IC50) | HDAC6 1 μM (IC50) | HDAC11 1.9 μM (IC50) |

体外研究 (In Vitro) | Tubulin/HDAC-IN-1 (Compound 12a, 72 h) shows cytotoxicity against various human cancer cell lines with an averaged IC50value of 0.6 nM[1]. Tubulin/HDAC-IN-1 (2 nM, 24 h) induces HT29 cell cycle arrest in the G2/M phase and produces caspase-induced apoptosis of HT29 cells through mitochondrial dysfunction[1]. Tubulin/HDAC-IN-1 selectively inhibits HDAC8 (IC50: 150 nM), inhibits HDAC6 and HDAC11 with IC50values of 1 μM and 1.9 μM respectively[1]. Tubulin/HDAC-IN-1 (0.5-100 nM, 24 h/30 min) dose-dependently increases γH2AX level and acetylated SMC3 in HT-29 cells[1]. Tubulin/HDAC-IN-1 (5-15 μΜ, 0-40 min) inhibits tubulin polymerization in a dose-dependent manner, with a maximal effect achieved at 10 μM[1]. Tubulin/HDAC-IN-1 (250 nM, 30 min) depolymerizes the cell microtubule network, and the effect is not specific[1]. Tubulin/HDAC-IN-1 shows goodin vitrometabolic stability expressed by the intrinsic clearance CLint (given in μL/min/mg protein) using rat liver microsomes (RLM) and human liver microsomes (HLM)[1].
