(S-DABOs). Chemical modifications at N-3, C-4, and C-6 of the pyrimidine ring were attempted with the aim of improving antiretroviral activity. In particular, replacement of the benzyl group with the 1-naphthylmethyl moiety enhanced the activity of S-DABOs, whereas N-3 alkylation and C=O transformation into C=S at position 4 of the pyrimidine ring led to compounds devoid of anti-HIV-1 activity.

已经合成了与2-(环己基硫基)-3,4-二氢-5-甲基-6-(3-甲基苄基)-4-氧嘧啶(3c,MC 639)相关的新型化合物,并已作为人免疫缺陷病毒类型的抑制剂进行了测试-1(HIV-1)。硫脲与芳基甲基乙酰乙酸乙酯反应,得到5-烷基-6-(芳基甲基)-3,4-二氢-2-巯基-4-氧嘧啶,然后在硫原子上烷基化,得到所需的2-烷硫基或2-环烷硫基衍生物(S-DABO)。为了改善抗逆转录病毒活性,尝试了在嘧啶环的N-3,C-4和C-6处进行化学修饰。特别是,用1-萘甲基甲基部分取代苄基可增强S-DABO的活性,而在嘧啶环的4位上N-3烷基化和C = O转化为C = S则导致化合物缺乏抗HIV-1活性。当1-萘甲基被异构体2-萘甲基取代时,通常观察到较低的活性。最具活性的化合物在低微摩尔范围内显示活性,其EC50值可与奈韦拉平相当。
