Abstract Novel tolmetin derivatives 5a–f to 8a–c were designed, synthesised, and evaluated for antiproliferative activity by NCI (USA) against a panel of 60 tumour cell lines. The cytotoxic activity of the most active tolmetin derivatives 5b and 5c was examined against HL-60, HCT-15, and UO-31 tumour cell lines. Compound 5b was found to be the most potent derivative against HL-60, HCT-15, and UO-31
摘要 NCI(美国)设计、合成了新型托美丁衍生物5a-f至8a-c,并针对 60 种肿瘤细胞系评估其抗增殖活性。检查了最具活性的托美丁衍生物5b和5c针对 HL-60、HCT-15 和 UO-31 肿瘤细胞系的细胞毒活性。化合物5b被发现是针对 HL-60、HCT-15 和 UO-31 细胞系最有效的衍生物,IC 50值分别为 10.32 ± 0.55、6.62 ± 0.35 和 7.69 ± 0.41 µM。进行了衍生物5b针对 VEGFR-2 活性位点的分子模型研究。化合物5b对 VEGFR-2 显示出高抑制活性 (IC 50 = 0.20 µM)。它极大地降低了 HUVEC 的迁移潜力,72 小时后表现出深度降低的伤口愈合模式。它诱导 HCT-15 细胞凋亡(52.72 倍)。凋亡 caspase-3、-8 和 -9 水平分别增加了 7.808、1.867 和 7.622 倍,支持了
