against free radicals and human cancer cell lines, HT29 (colon cancer) and MCF7 (breast cancer) were further evaluated. The experimental results showed that the Six out-of-eight S-BHT compounds had excellent antioxidant activity against DPPH radical with major enhancement compared to BHT. Among them, compounds 2b, 2a and 3b attained over 45% lower IC50 values than BHT. In vitro cytotoxicity, MTT assay
摘要在本研究中,合理设计和合成了一系列多能抗氧化剂(MPAO),即含硫BHT(S-BHT)衍生物,它们对自由基和人类癌细胞系HT29(结肠癌)具有抑制作用和MCF7(乳腺癌)进行了进一步评估。实验结果表明,八种S-BHT化合物中,六种具有抗DPPH自由基的抗氧化活性,与BHT相比具有显着增强。其中,化合物2b,2a和3b的IC 50值比BHT低45%以上。体外对于细胞毒性,MTT分析使用两种人类癌细胞系HT29(结肠癌)和MCF7(乳腺癌)以及它们的非致瘤对应物进行,以探索选择性。与抗氧化剂活性一致,化合物2a和2b对两种癌症均显示出最高的细胞毒性作用。有趣的是,2b不仅在结肠和乳腺组织中表现出优异的癌症抑制作用,而且分别具有较高的选择性指数(SI = 5.2,12.5),超过了使用5-氟尿嘧啶(5-FU)和他莫昔芬(Tmx ),IC 50较低价值观。结果表明,对称的S-BHT衍生物被抗氧
