This paper reports the synthesis and the antiviral activities of a series of 6-arylmethyl-1-(allyloxymethyl)-5-alkyluracil derivatives, which can be viewed as analogues of the anti-HIV-1 drug emivirine (formerly MKC-442) from which they differ in the replacement of the ethoxymethyl group with variously allyloxymethyl moieties. The most active compounds N-1 allyloxymethyl- and N-1 3-methylbut-2-enyl
本文报道了一系列6-芳基甲基-1-(烯丙氧基甲基)-5-烷基尿嘧啶衍生物的合成和抗病毒活性,这些衍生物可被视为抗HIV-1药物emivirine(以前为MKC-442)的类似物。它们在用各种烯丙氧基甲基部分取代乙氧基甲基上有所不同。活性最高的化合物N-1烯丙氧基甲基和N-1 3-甲基丁-2-烯基取代的5-乙基-6-(3,5-二甲基苄基)尿嘧啶(12和13)在HIV-1野生型中表现出活性。皮摩尔范围的选择性指数大于5 x 10(6),并且在亚微摩尔范围内具有对临床上重要的已知对埃米韦林具有抗性的Y181C和K103N突变株的活性。
