A series of fourteen polysubstituted 7-chloro-4-quinolinylhydrazone derivatives (3a-n) has been synthesized and evaluated for their activity against four cancer cell lines. Among them, compounds 3a, 3c, 3h, 3i, 3j and 3n showed good cytotoxicity (with IC50 ranging from 0.7483 to 5.572 μg/mL). In general, we observed that the presence of methoxy groups on benzene ring plays an important role in the anticancer activity of this series, especially when they are located in 3,4 (3h) or 3,4,5 (3j) positions. These derivatives could be considered a relevant finding towards the rational design of new leads for antitumoral agents.
我们合成了一系列多取代的 7-氯-4-喹啉腙衍生物(3a-n),并评估了它们对四种癌细胞株的活性。其中,化合物 3a、3c、3h、3i、3j 和 3n 显示出良好的细胞毒性(IC50 范围为 0.7483 至 5.572 μg/mL)。总的来说,我们观察到苯环上甲氧基的存在对该系列化合物的抗癌活性起着重要作用,尤其是当甲氧基位于 3,4 (3h)或 3,4,5 (3j)位时。这些衍生物可被视为合理设计抗肿瘤药物新线索的一个重要发现。
