2'-anhydro derivatives of ara-C were synthesized as potential prodrugs of ara-C 5'-monophosphate (ara-CMP). Alkylphosphorylation of ara-C, N4-palmitoyl-ara-C, and N4-stearoyl-ara-C was achieved in a single continuous operation by allowing the nucleoside to react with POCl3 in trimethyl or triethyl phosphate and adding the appropriate anhydrous alcohol directly to the intermediate phosphorodichloridate without
合成了1-β-D-阿拉伯呋喃糖基胞嘧啶(ara-C)的亲脂5'-(烷基磷酸酯)酯和ara-C的几种N4-酰基和3'-O-酰基-2,2'-脱水衍生物ara-C 5'-单磷酸盐(ara-CMP)的前药。ara-C,N4-棕榈酰基-ara-C和N4-硬脂酰基-ara-C的烷基磷酸化可通过使核苷与POCl3在磷酸三甲酯或磷酸三乙酯中反应,然后将适当的无水乙醇直接加入无需分离即可得到中间体二氯化磷。胞苷的类似反应产生胞苷5'-(磷酸烷基酯),在三氟化硼存在下用肉豆蔻酰氯或棕榈酰氯处理后,得到3'-O-酰基-2,2'-脱水芳基-C 5'- (磷酸烷基酯)。Ara-C 5'-(磷酸正丁酯)(1b),N4-棕榈酰基-芳基-C 5'-(磷酸正丁酯)(1h)和2,2'-脱水-3'-O-棕榈酰基-芳基-C 5'-(磷酸正丁酯)(2h)在小鼠中对L1210 / ara-C白血病进行了测试,希望该激酶缺陷型肿瘤对使
