5'-(Bromoacetamido)-2',5'-dideoxyuridine (3) and derivatives (8, 10, 12, and 14) substituted at the 5-position with bromo, iodo, fluoro, and ethyl groups have been synthesized as potential inhibitors of enzymes that metabolize pyrimidine nucleosides. Also prepared were 2',5'-dideoxyuridine derivatives (4-6) substituted at the 5'-position with 2-bromopropionamido, iodoacetamido, and 4-(fluorosulfonyl)benzamido
已经合成了5'-(Bromoacetamido)-2',5'-dideoxyuridine(3)和在5位上被溴,碘,氟和乙基取代的衍生物(8、10、12和14)代谢嘧啶核苷的酶的抑制剂。还制备了在5'-位被2-溴丙酰胺基,碘代乙酰胺基和4-(氟磺酰基)苯甲酰胺基取代的2',5'-二脱氧尿苷衍生物(4-6)。检查了化合物3、5、8、12和14对培养的L1210白血病细胞中大分子合成的影响,并将其与5'-(溴乙酰胺基)-5'-脱氧胸苷(1,BAT)进行了比较,该化合物具有明显的细胞毒性和抗P388鼠白血病的体内活性。化合物3、8、12和14抑制DNA合成,而没有明显抑制RNA合成,蛋白质合成受到的影响小于DNA合成。化合物3、5、6、8、10、12和14对培养的H.Ep.-2和L1210细胞具有细胞毒性,而3、5、8和12在P388小鼠白血病筛选中显示活性。
