intracellular metabolism. Compound 14 as well as adenallene derivative 15c were devoid of anti-HIV activity, and they also failed to inhibit HIV reverse transcriptase. A new regioselective method for preparation of (Z)-4-(benzoyloxy)-1-hydroxy-2-butene, 7, a key intermediate for the synthesis of unsaturated nucleoside analogues of cis configuration such as 3a, 3b, and 3c, is also described.
研究了引入亲脂性磷酸二酯a酰胺部分对非活性不饱和核苷类似物的HIV活性的影响。合成了衍生自不饱和核苷类似物3b,3c和4a的磷酸二酯丙氨酸盐5a,5b和6,并研究了它们在ATH-8细胞中对细胞病变作用和HIV-1复制的抑制作用。化合物5a是HIV-1的抑制剂,而类似物6是无活性的,细胞毒性出现在10μM以上,而5b是无活性的和无毒的。5a的碱水解或酶水解得到磷酸单酯丙氨酸酯14,它是细胞内代谢的假定产物。化合物14以及腺嘌呤衍生物15c没有抗HIV活性,并且它们也不能抑制HIV逆转录酶。
