multistep synthesis. The structures of synthesized compounds were confirmed by their IR, 1H NMR, 13C NMR, and HR-ESI-MS spectroscopic data. The inhibitory activity of all the target compounds was determined toward three human cancer cell lines including SMMC-7721, A549, Hela, and the normal cell line L929 by CCK-8 assay. Meanwhile, all compounds were evaluated for their in vitro antimicrobial activities
本研究通过多步合成制备了24种2-芳氨基-5-取代二硫烷基-1,3,4-噻二唑。合成化合物的结构通过其 IR、1 H NMR、13 C NMR 和 HR-ESI-MS 光谱数据证实。通过CCK-8法测定了所有目标化合物对SMMC-7721、A549、Hela和正常细胞系L929三种人癌细胞系的抑制活性。同时,评估了所有化合物对革兰氏阴性菌大肠杆菌和革兰氏阳性菌金黄色葡萄球菌的体外抗菌活性。菌株。获得的数据显示,所有受试化合物都显示出一定程度的抗增殖活性,并且一些化合物对各种癌细胞的作用优于参考药物 5-FU 和 PX-12。特别是化合物8c、8e和8f对SMMC-7721细胞表现出优异的生长抑制作用,IC 50值分别为3.22、3.21和2.86 μM。化合物8e对A549细胞表现出最大的抑制活性,IC 50值为4.29 μM。发现化合物8a对 Hela 细胞具有最强的抗肿瘤活性,IC 50值
