compounds show significant antiproliferative activity with IC50 in the range of 0.077–122 μM against human melanoma cell line (A375). Direct inhibition of tubulin polymerization assay in vitro is also assessed. Results show that compounds 6b, 6e, 6g, and EAPB0503 highly inhibit tubulin polymerization with percentages of inhibition of 99%, 98%, 90%, and 84% respectively. Structure–activity relationship
微管被认为是抗癌治疗的重要目标。EAPB0503及其结构咪唑并[1,2- a ]喹喔啉衍生物是具有有效抗癌活性的主要微管干扰剂。在这项研究中,描述了几种新的EAPB0503衍生物的合成,并报道了13种新衍生物对A375人黑素瘤细胞系的抗癌作用。所有新化合物对人黑素瘤细胞系(A375)的IC 50均显示出显着的抗增殖活性,其IC 50值为0.077–122μM。还评估了体外对微管蛋白聚合测定的直接抑制。结果表明,化合物6b,6e,6g和EAPB0503高度抑制微管蛋白的聚合,抑制百分比分别为99%,98%,90%和84%。该系列中的结构-活性关系研究也与微管蛋白秋水仙碱结合位点的分子对接研究进行了讨论。
