A range of lipophilic prodrugs of α-carboxy nucleosidephosphonates, potent inhibitors of HIV-1 reverse transcriptase without requiring prior phosphorylation, were synthesized to evaluate their in vivo potency against HIV in cell culture. A series of prodrug derivatives bearing a free carboxylic acid where the phosphonate was masked with bispivaloyloxymethyl, diisopropyloxycarbonyloxymethyl, bisamidate
合成了一系列 α-羧基核苷膦酸盐的亲脂性前药,无需事先磷酸化即可有效抑制 HIV-1 逆转录酶,以评估它们在细胞培养中对 HIV 的体内效力。合成了一系列带有游离羧酸的前药衍生物,其中膦酸酯被双新戊酰氧基甲基、二异丙氧基羰基氧基甲基、双酰胺酸酯、芳氧基氨基磷酸酯、十六烷氧基丙基、CycloSal 和环氧基苄基部分掩蔽,采用现有的膦酸酯保护方法以适应相邻的羧酸部分。在 CEM 细胞培养物中测定前药的抗 HIV 活性——双新戊酰氧甲基游离酸单膦酸盐前药表现出一定的活性(抑制浓度 - 50(IC 50) 59 ± 17 μM),而其他前药在 100 μM 时无活性。还制备了外消旋双新戊酰氧基甲基甲酯单膦酸酯前药,以评估甲酯作为羧酸前药的适用性。该化合物在细胞试验中没有表现出抗 HIV 活性。
