In our previous work, novel 2,4,5-trisubstituted thiazole derivatives (TSTs) were synthesized, and their activities were evaluated against HIV-1 reverse transcriptase. Some interesting results were obtained, which led us to a new discovery regarding these TST5. In the present study, 21 new 2,4,5-trisubstituted thiazole derivatives were rationally designed and synthesized as HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) in accordance with our previous study. Among the synthesized target compounds, compounds 14, 16, 17, and 19 showed more potent inhibitory activities against HIV-1 with an IC50 value of 0.010 mu M. Compounds 4, 9, 10, 11, 13 and 16 were further tested on nine NNRTI-sresistant HIV-1 strains, and all of these compounds exhibited inhibitory effects. A molecular docking study was conducted, and the results showed a consistent and stable binding mode for the typical compounds. These results have provided deeper insights and SAR of these types of NNRTIs. (C) 2016 Elsevier Masson SAS. All rights reserved.
