than the corresponding open counterparts (PASs); ii) the DMA group give the highest anti-HIV-1 potency in the PBTAs series; iii) PBTAs and the corresponding thiones are equipotent; iv) an unsubstituted amino group, as part of p-chloroanilino moiety, is a strong determinant for the antiviral activity in the PASs series. The most potent derivatives in cell-based assays were proven to target the RT in enzyme
设计,合成和测试了许多2H-吡咯并[3,4-b] [1,5]苯并硫氮杂derivatives衍生物(PBTA)7-25和相关的合成中间体3-吡咯基芳基砜(PAS)26-32抗HIV-1药物靶向逆转录酶(RT)。PBTA被认为是奈韦拉平,吡咯并[1,2-b] [1,2,5]苯并噻二氮杂5(PBTD)和吡咯并[2,1-d] [1,2,5]苯并噻二氮杂6,NNRTIs的三环类似物。具有强大的抗HIV-1活性。大多数测试的PBTA在0.3至40 microM的浓度下对MT-4细胞中HIV-1诱导的细胞病变具有活性。特别是,化合物10是最有效的衍生物,EC50 = 0.3 microM,与用作参考药物的奈韦拉平相当。在3-吡咯基芳基砜(26-32)系列中,仅发现三种砜具有抗HIV-1复制周期的活性。以下是标题衍生词的初步SAR:i)构象受限的PBTA比相应的开放式对应物(PAS)更有效;ii)DMA
