reaction of 5-fluoro-2'-deoxyuridine (7a) and phosphoryl chloride with 3-amino-1-propanol and 1,3-propanediol, respectively. The thymidine analogues, 1c and 1d, were prepared similarly from thymidine. Compound 1b was synthesized in better yield from 13a and trimethylene phosphate with triphenylphosphine/diethyl azodicarboxylate as a condensing agent. Compounds 1a-d were resistant to degradation by 5'-nucleotidase
5-氟-5'-(2-氧代-1,3,2-氧杂氮杂膦酸-2-基)-2'-脱氧尿苷(1a)和5-氟-5'-(2-氧代-1,3,2通过使5-氟-2'-脱氧尿苷(7a)和磷酰氯分别与3-氨基-1-丙醇和1,3-丙二醇反应制得-二氧杂磷酰胺基-2-基)-2'-脱氧尿苷(1b)。 。胸苷类似物1c和1d类似地由胸苷制备。以三苯基膦/偶氮二羧酸二乙酯为缩合剂,由13a和磷酸三亚甲基酯以较好的收率合成了化合物1b。化合物1a-d对5'-核苷酸酶,碱性磷酸酶,毒磷酸二酯酶和粗蛇毒具有抗降解性。当在产生NADPH的系统中与小鼠肝微粒体制剂一起温育时,这些化合物均未发生明显的生物转化。当连续5天腹膜内(ip)给药时,1a在延长腹膜内植入白血病P-388的BDF1小鼠的寿命方面几乎与5-氟尿嘧啶一样。但是,要想获得最佳活性,就需要更大剂量的1a。类似地施用的化合物1b仅勉强有效。1a和1b都没有针对抗5-氟尿嘧啶的P-388突变体的活性。
