In this study, twenty-nine coumarin-3-sulfonamide derivatives, twenty-seven of which are original were designed and synthesized. Cytotoxicity assay indicated that most of these derivatives exhibited moderated to good potency against A549 cells. Among them, compound showed potent inhibition against the four tested cancer cell lines, especially A549 cells with IC value of 6.01 ± 0.81 μM, and much lower
本研究设计合成了29种香豆素-3-磺酰胺衍生物,其中27种是原创的。细胞毒性测定表明,大多数这些衍生物对 A549 细胞表现出中等至良好的效力。其中,化合物对四种测试的癌细胞系显示出有效的抑制作用,特别是A549细胞,IC50值为6.01±0.81μM,与参考化合物相比,对正常细胞的细胞毒性显着降低。生物信息学分析显示,人碳酸酐酶 IX (CAIX) 在肺腺癌 (LUAD) 中高表达,且与不良预后相关。通过分子对接和分子动力学模拟评估了化合物对 CAIX 的抑制活性,结果揭示了化合物和 CAIX 在活性位点的显着相互作用以及它们的高亲和力。 ELISA检测结果证实该化合物对CAIX具有较强的抑制活性和较高的亚型选择性,并能下调A549细胞中CAIX的表达。此外,还发现化合物对A549细胞的迁移和侵袭具有显着的抑制作用。用化合物处理后,细胞内活性氧(ROS)水平升高,线粒体膜电位(MMP)降
