在我们之前的工作中,合成了新型2,4,5-三取代噻唑衍生物(TST),并评估了它们针对HIV-1逆转录酶的活性。获得了一些有趣的结果,这使我们对这些 TST 有了新的发现。本研究根据前期研究合理设计合成了21种新型2,4,5-三取代噻唑衍生物作为HIV-1非核苷类逆转录酶抑制剂(NNRTIs)。在合成的目标化合物中,化合物14、16、17和19对HIV-1表现出更强的抑制活性,IC50值为0.010 μM。化合物4、9、10、11、13和16进一步在9种NNRTI耐药HIV-1毒株上进行测试,所有这些化合物均表现出抑制作用。进行了分子对接研究,结果显示典型化合物具有一致且稳定的结合模式。这些结果为这些类型的 NNRTI 提供了更深入的见解和 SAR。
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 TSTs. 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, compounds14,16,17, and19showed more potent inhibitory activities against HIV-1 with an IC50value of 0.010 μM. Compounds4,9,10,11,13and16were further tested on nine NNRTI-resistant 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.
