and O-ethyl derivatives of 2'-deoxy-5-(trifluoromethyl)uridine (F3Thd) and 2'-deoxy-5-fluorouridine (FUdR) were synthesized. The oral antitumor activity of the compounds against sarcoma 180 in mice was examined. The 5'-O-ethyl (3b), 3'-O-ethyl (3c), 5'-O-benzyl (3e), and 3'-O-benzyl (3f) derivatives of F3Thd were 4-fold more active than F3Thd itself. Among the substituted-benzyl derivatives of F3Thd,
合成了2'-脱氧-5-(三氟甲基)尿苷(F3Thd)和2'-脱氧-5-氟尿苷(FUdR)的O-苄基和O-乙基衍生物。检查了化合物对小鼠肉瘤180的口服抗肿瘤活性。F3Thd的5'-O-乙基(3b),3'-O-乙基(3c),5'-O-苄基(3e)和3'-O-苄基(3f)衍生物的活性高4倍比F3Thd本身。在F3Thd的取代苄基衍生物中,3'-O-(对氯苄基)-F3Thd(3h)显示最高的活性,ED50不到F3Thd的十分之一。FUdR的5'-O-苄基(7c)和3'-O-苄基(7d)衍生物的活性与F3Thd的有效O-烷基衍生物的活性相等。
