suggested that the substitution of the nitro group at 6′ position of the C-2 phenyl ring and 4,6-dimethylpyridin-2-yl at the N-3 position of thiazolidin-4-one had a major impact on the anti-HIV-1 activity and was found to lower cytotoxicity. The substitution of the heteroaryl ring with bromo group and bicyclic heteroaryl ring at N-3 thiazolidin-4-one was found to lower anti-HIV-1 activity and increase
已经研究了一系列新颖的噻唑烷酮-4-酮类似物,其特征在于噻唑烷酮-4-酮骨架的C-2和N-3位置具有不同的抗HIV-1活性。当在TZM-b1细胞中进行体外测试时,大多数化合物在微摩尔浓度下均具有抗HIV-1活性。在所测试的33种化合物中,化合物16是针对HIV-1 IIIB, HIV-1 ADA5,HIV-1 UG070和HIV-1 VB59的HIV-1复制的最有效抑制剂(EC 50 分别为0.02、0.08、0.08和0.08μM),分别具有针对被测病毒株的选择性指数(SI = 6940、1735、1692和1692)。本研究结果表明,在噻唑烷丁-4-one N-3位的C-2苯环6'位置的硝基取代和在N-3位的4,6-二甲基吡啶-2-基的取代主要是影响抗HIV-1活性,并被发现可降低细胞毒性。发现在N-3噻唑烷-4--1-酮上用溴基和双环杂芳基环取代杂芳基环可降低抗HIV-1活性并增加细
