activities were evaluated as potential telomerase inhibitors. Among the oxadiazole derivatives, compound 5c showed the most potent biological activity against SW1116 cancer cell line (IC50 = 2.46 μM against SW1116 and IC50 = 3.55 μM for telomerase). Compound 8h performed the best in the thiadiazole derivatives (IC50 = 0.78 μM against HEPG2 and IC50 = 1.24 μM for telomerase), which was comparable to the
已设计,合成,结构确定了三系列含有吡嗪的新型杂环唑类衍生物(5a - 5k,8a - 8k和11a - 11k),并评估了它们的生物活性作为潜在的端粒酶抑制剂。间的恶二唑衍生物,化合物5c中显示针对SW1116癌细胞系的最有效的生物活性(IC 50 = 2.46μM针对SW1116和IC 50 = 3.55μM端粒酶)。化合物8h在噻二唑衍生物中表现最好( 针对HEPG2和IC 50的IC 50 = 0.78μM 端粒酶的浓度为1.24μM),与阳性对照相当。而化合物11F显示出最有效的生物活性(IC 50 = 4.12μM针对SW1116和IC 50 的三唑衍生物中= 15.03μM端粒酶)。通过将化合物5c,8h和11f置于端粒酶结构活性位点进行对接模拟,以探索可能的结合模型。凋亡的结果表明化合物8h对HEPG2癌细胞系具有良好的抗肿瘤活性。因此,化合物8h在肿瘤生长中具有强抑制
