revealed the antiproliferative activity of 7h while depolarization of mitochondrial membrane potential by JC-1 was observed in dose-dependent manner. Cell cycle analysis also unveiled the typical accumulation of cells in G2M phase and sub-G1/S phase arrest. In addition, immunoblot analysis for compound 7h on HCT-15 indicated selective inhibition of the protein expression of class I HDAC 2 and 3 isoforms. Molecular
在本研究中检测了 β-咔啉基序作为含有肉桂酸作为接头和苯甲酰胺作为锌结合基团的 HDAC 抑制剂的作用。已经合成了一系列 β-咔啉-肉桂酰胺偶联物,并评估了它们对不同人类癌细胞系的 HDAC 抑制活性和体外细胞毒性。几乎所有的化合物都表现出比标准药物恩替司他更出色的 HDAC 抑制活性。在测试的化合物中,与标准药物Entinostat (IC 503.87 ± 0.62 µM)。传统的细胞凋亡测定,如核形态改变、AO/EB、DAPI 和 Annexin-V/PI 染色显示7小时的抗增殖活性,而 JC-1 对线粒体膜电位的去极化以剂量依赖性方式观察到。细胞周期分析还揭示了细胞在 G 2 M 期和亚 G 1 /S 期停滞的典型积累。此外,化合物7 h在 HCT-15 上的免疫印迹分析表明选择性抑制 I 类 HDAC 2 和 3 同种型的蛋白质表达。化合物7h的分子对接分析揭示它可以与 HDAC
