2'-Deoxy-3',5'-di-O-alkylcarbonyl-5-fluorouridine derivatives possessing strong anti-tumor activity with weak toxicity and represented by the general formula: ##STR1## wherein R stands for an alkyl group, an alkoxy group or a halogen atom, m for zero or an integer of 1-3, and n for an integer of 1-14, with the proviso that when m is 2 or 3, R's may be the same or different and that when m is 2 and the adjacent two R's are alkoxy groups, the two alkyl moieties of the alkoxy groups may be combined to form together with the two adjacent oxa bridging members an alkylenedioxy group as a whole. These derivatives are prepared by acylating a 2'-deoxy-3',5'-di-O-alkylcarbonyl-5-fluorouridine with corresponding benzoyl halides and are useful as active ingredients for anti-tumor agents, especially for oral administration.
具有强抗肿瘤活性和弱毒性的2'-脱氧-3',5'-二-O-烷基羰基-5-氟尿嘧啶衍生物,其通式表示为:##STR1## 其中R代表烷基、烷氧基或卤素原子,m为零或1-3的整数,n为1-14的整数,但当m为2或3时,R可能相同或不同,且当m为2且相邻的两个R为烷氧基时,两个烷氧基的两个烷基部分可以结合形成整体的烷二氧基基团,与两个相邻的氧杂环桥接成员一起。这些衍生物通过使用相应的苯甲酰卤制剂酰化2'-脱氧-3',5'-二-O-烷基羰基-5-氟尿嘧啶制备而成,可用作抗肿瘤剂的活性成分,特别适用于口服给药。
