High-yield regioselective syntheses of 9-[(1,3-dihydroxy-2-propoxy)methyl]guanine mono-, di- and tri-substitution derivatives as potential prodrugs were accomplished via one or multisteps. Two amino acid esters of ganciclovir were synthesized as water-soluble prodrugs, which form protonated cations in pH 7.4 phosphate buffer.
9-[(1,3-二羟基-2-丙氧基)甲基]鸟嘌呤单,双和三取代衍生物作为潜在前药的高产区选择性合成是通过一个或多个步骤完成的。合成了更昔洛韦的两种氨基酸酯作为水溶性前药,它们在pH 7.4磷酸盐缓冲液中形成质子化阳离子。
