Various O-alkyl derivatives of 2'-deoxy-5-fluorouridine (FUdR) were synthesized and their antitumor activities in mice bearing sarcoma 180 (s.c.-p.o.) were evaluated in terms of the ED50 values (mg/kg/d). Most of these compounds were superior to FUdR in antitumor activity. In particular, the antitumor activity of 3'-O-(p-chloro-benzyl)-FUdR (3e) (ED50 = 0.87 mg/kg/d) was as much as 100 times that of
合成了2'-脱氧-5-氟尿苷(FUdR)的各种O-烷基衍生物,并根据ED50值(mg / kg / d)评估了它们在肉瘤180(sc-po)小鼠中的抗肿瘤活性。这些化合物中的大多数在抗肿瘤活性方面均优于FUdR。特别是3'-O-(对氯苄基)-FUdR(3e)(ED50 = 0.87 mg / kg / d)的抗肿瘤活性是FUdR(ED50 = 84 mg / kg)的100倍/ d)。此外,合成了各种3e的5'-O-氨基酰基衍生物,并根据ED50值和治疗指数(TI)进行了评估。3'-O-(对氯苄基)-5'-O-甘氨酰-FUdR盐酸盐(6a)的ED50值(0.41 mg / kg / d)和TI(4.18)均显着提高。 3e和FUdR。单次给药6a后,FUdR血浆浓度可维持长达24小时。
