BACKGROUND Based on the biological significance of benzisoselenazolone and 1,3,4-thiadiazole, a series of novel 1,3,4-thiadiazole derivatives incorporating benzisoselenazolone scaffold were designed and synthesized with ebselen as a lead compound. METHODS Meanwhile, their in vitro antitumor activities were evaluated against SMMC-7721, MCF-7 and A549 human cancer cell lines by CCK-8 assay. RESULTS The
背景技术基于苯并异硒唑啉酮和1,3,4-噻二唑的生物学意义,设计并合成了一系列以苯并硒化硒唑啉酮骨架为原料的新型1,3,4-噻二唑衍生物。方法同时,通过CCK-8检测其对SMMC-7721,MCF-7和A549人癌细胞的体外抗肿瘤活性。结果初步的生物测定结果表明,所有测试的化合物4a-q均显示出强大的抗肿瘤活性,并且某些化合物对多种癌细胞系的阳性对照比乙醇/乙草胺和5-氟尿嘧啶(5-FU)更好。此外,化合物4b和4m对SMMC-7721细胞显示出显着的抗肿瘤活性,IC50值分别为1.89和1.89μM。化合物4c和4n对MCF-7细胞表现出高度有效的生物学活性,IC50值分别为2.88和2.28μM。化合物4i对A549细胞表现出最佳的抑制作用,IC50值为1.76μM。结论药理结果表明1,3,4-噻二唑上苯环的取代基对于调节针对多种癌细胞系的抗肿瘤活性至关重要。
