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) |
