synthesized through the azide/alkyne dipolar cycloaddition. Hybrid molecules were evaluated for their cytotoxic activity against four cancer cell lines (e.g., HuCCA-1, HepG2, A549 and MOLT-3) and antimalarial activity toward Plasmodium falciparum. Most of the synthesized hybrids, except for analogs 10 and 16, displayed cytotoxicity against MOLT-3 cell line without affecting normal cells. Analogs (10
一系列新的查耳酮,香豆素衍生物(的9 - 19)由1,2,3-三唑环连接是通过叠氮化物/炔偶极环加成来合成。评价杂合分子对四种癌细胞系(例如,HuCCA-1,HepG2,A549和MOLT-3)的细胞毒性活性和对恶性疟原虫的抗疟活性。除类似物10和16外,大多数合成的杂种均显示出对MOLT-3细胞系的细胞毒性,而不会影响正常细胞。类似物(10,11,16和18)在HepG2细胞中显示出比对照药物依托泊苷更高的抑制作用。显着地,杂种11的高细胞毒性效力显示为对正常细胞无毒。有趣的是,查耳酮-香豆素18是最有效的抗疟疾化合物,IC 50值为1.60μM。分子对接表明,报道的杂种的细胞毒性可能是由于它们分别在GTP和秋水仙碱结合位点对α-和β-微管蛋白的双重抑制。此外,鉴于其抗疟疾效力,falcipain-2被确定为杂种的合理目标位点。
