To yield potent HIV-1 non-nucleoside reverse transcriptase inhibitors (NNRTIs) with favorable drug-like properties, a series of novel diarylpyrimidine derivatives targeting the tolerant region I of the NNRTI binding pocket were designed, synthesized and biologically evaluated. The most active inhibitor 10c exhibited outstanding antiviral activity against most of the viral panel, being about 2-fold
为了产生具有良好的药物样性质的有效的HIV-1非核苷逆转录酶抑制剂(NNRTIs),设计,合成和生物学评估了一系列靶向NNRTI结合口袋的I区的新型二芳基嘧啶衍生物。活性最高的抑制剂10c对大多数病毒板均表现出出色的抗病毒活性,约为2倍(野生型,EC 50 = 0.0021μM),1.7倍(K103N,EC 50 = 0.0019μM),并且效力更强(E138K,EC 50 = 0.0075μM )比NNRTI药物依曲韦林(ETR)高。此外,赋予10c较低的细胞毒性(CC 50 = 18.52μM)。更重要的是10c与ETR相比,Fsp 3具有改善的类药物特性,且Fsp 3(sp 3碳原子的分数)值增加。此外,进行了分子动力学模拟和分子对接研究以揭示10c在结合口袋中的结合模式。两者合计,10c是有前途的铅化合物,值得进一步研究。
