Cyclooxygenase-2 is frequently overexpression in malignant tumors and the product PGE2 promotes cancer cell progression and metastasis. We designed novel series of coumarin sulfonamides derivatives to improve biological activities of COX-2 inhibition and anticancer. Among them, compound 7t showed most powerful selective inhibitory and antiproliferative activity (IC50 = 0.09 μM for COX-2, IC50 = 48
环氧合酶2在恶性肿瘤中经常过度表达,产物PGE 2促进癌细胞的发展和转移。我们设计了一系列香豆素磺酰胺衍生物,以改善COX-2抑制和抗癌的生物活性。其中,化合物7吨表明最强大的选择性的抑制和抗增殖活性(IC 50 = 0.09μM为COX-2,IC 50 = 48.20μM为COX-1,IC 50 = 0.36μM对HeLa细胞),具有可比性到控制正化合物塞来昔布(0.31μM,43.37μM,7.79μM)。进行癌细胞凋亡测定,结果表明化合物7t以剂量和时间依赖性有效地促进HeLa细胞凋亡。此外,7t可以显着抑制癌细胞的粘附,迁移和侵袭,这是癌症转移的重要过程。对接模拟结果进一步表明,化合物7t可以很好地与COX-2活性位点结合,并在将来指导合理设计具有抗癌活性的选择性COX-2抑制剂。
