Abstract
Inspired by our previous studies to discover novel human immunodeficiency virus-1(HIV-1)non-nucleoside reverse transcriptase inhibitors(NNRTIs)by targeting the tolerant region Ⅱ of the NNRTIs binding pocket(NNIBP),a series of novel benzo[4,5]thieno[2,3-d]pyrimidine derivatives were designed through structure-based drug design as novel potent HIV-1 NNRTIs.The results showed that compound 16b was the most active inhibitor,exhibiting 50%effective concentration(EC50)values from 0.021 μmol/L to 0.298 μmol/L against wild-type(WT)and a panel of NNRTIs-resistant HIV-1 strains.Moreover,16b was demonstrated with a significantly low 50%cytotoxicity concentration(CC50)value(>200μmol/L)and high selectivity index(SI)values.In addition,16b yielded moderate reverse transcriptase(RT)enzyme inhibi-tion with a 50%inhibition concentration(IC50)value of 0.183 μmol/L,which demonstrated that it acted as HIV-1 NNRTIs.The binding mode of 16b with RT was also illustrated via molecular docking.Overall,this work provided a novel lead compound for developing potent HIV-1 NNRTIs.
