5-alkyl-2-arylthio-6-((3,4-dihydroquinolin-1(2H)-yl)methyl)pyrimidin-4(3H)-ones were synthesized and evaluated as inhibitors of human immunodeficiency virus type-1 (HIV-1). Among them, the most potent HIV-1 inhibitors were compounds 6c1, 6c6, and 6b1 (EC50 = 0.24 ± 0.05, 0.38 ± 0.13, 0.39 ± 0.05 μM, respectively), which possess improved or similar HIV-1 inhibitory activity compared with nevirapine (NVP) (EC50 = 0
合成并评价了一系列5-烷基-2-芳硫基-6-((3,4-二氢喹啉-1(2H)-基)甲基)嘧啶-4(3H)-的新颖的S -DABO类似物作为人类1型免疫缺陷病毒(HIV-1)的抑制剂。其中,最有效的HIV-1抑制剂化合物6C1,6C6和6B1(EC 50 = 0.24±0.05,0.38±0.13,0.39±0.05μM,分别地),其具有改善的或类似的HIV-1抑制活性相比奈韦拉平(NVP)(EC 50 = 0.21μM)和地拉夫定(DLV)(EC 50 = 0.32μM)。这些化合物都不具有抗HIV-2复制的活性。此外,用针对HIV-1 wtRT的选定衍生物进行了酶抑制试验,证实了这些化合物的主要靶标是HIV-1 RT,并且这些新的S -DABOs充当NNRTIs。这些新的同类物的初步结构-活性关系(SAR)进行了简要讨论,并通过对接研究进行了合理化。
