the 5'-monophosphates showing comparable potencies. The corresponding 3',5'-cyclic monophosphate diesters were 20-30 times less potent but nonetheless highly cytostatic. All derivatives including 11-15 had greatly increased ID50 values for the thymidine kinase deficient (TK-) L1210 and Raji cells. The 3',5'-cyclic diesters (11-15) evidently are not efficient prodrug sources of the nucleoside 5'-monophosphates
标题二酯(11-15;卤素取代基F,Cl,Br,I)是通过DCC诱导的前体5'-单磷酸环化或2'-脱氧尿苷3',5'-环单磷酸的直接卤化制备的。将细胞系统(L1210和Raji / 0)中11-15的抗肿瘤活性与相应核苷和5'-单磷酸酯的抗肿瘤活性进行了比较。因此,5-F-和5-CF3-2'-脱氧尿苷被证明是高活性衍生物[L1210的ID50值(微克/ mL),分别为0.002和0.06],而5'-单磷酸酯显示出可比的效能。相应的3',5'-环一磷酸二酯的效力降低了20-30倍,但仍具有高度的细胞抑制作用。包括11-15在内的所有衍生物对于胸苷激酶缺陷(TK-)L1210和Raji细胞的ID50值均大大提高。3',5' -环二酯(11-15)显然不是TK细胞中核苷5'-单磷酸的有效前药来源。他们还被证明是L1210胸苷酸合成酶抑制剂的效率比5'-单磷酸酯低100-2000倍。5-取代的2'
