A series of 7,8-dihydroxy-4-arylcoumarins, the derivatives related to DW532 that was an
anti-tumor agent targeting both kinase and tubulin, was prepared by Suzuki coupling reaction. Among
them, compounds 6a, 6b, and 6c were found to exhibit anti-proliferation activities against human
breast carcinoma MDA-MB-468 cells with IC50 values of 0.64, 0.69, and 1.33 μM, respectively and
human epidermoid carcinoma A431 cells with IC50 values of 2.56, 1.78, and 2.29 μM, respectively.
Further evaluation of the selected molecules revealed that they displayed broad-spectrum inhibitory
activities against a panel of kinases including Flt-1, VEGFR2, RET, EGFR, etc. In vitro tubulin polymerization assay and
molecular docking indicated that the substitution of 3’-OH and 4’-OCH3 on the 4-phenyl ring was essential to achieve potent
tubulin inhibition.
通过铃木偶联反应制备了一系列7,8-二羟基-4-芳基香豆素,它们是与DW532相关的衍生物,DW532是一种靶向激酶和微管蛋白的抗肿瘤药物。其中,化合物 6a、6b 和 6c 对人乳腺癌 MDA-MB-468 细胞具有抗增殖活性,IC50 值分别为 0.64、0.69 和 1.33 μM;对人表皮样癌 A431 细胞具有抗增殖活性,IC50 值分别为 2.对所选分子的进一步评估表明,它们对包括 Flt-1、血管内皮生长因子受体 2、RET、表皮生长因子受体等在内的一系列激酶具有广谱的抑制活性。体外微管蛋白聚合试验和分子对接表明,4-苯基环上 3'-OH 和 4'-OCH3 的取代是实现强效微管蛋白抑制的关键。
