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.
2'-脱氧-3',5'-双-O-烷基羰基-5-氟尿苷衍生物具有强烈的抗肿瘤活性,毒性较弱,通式如下:其中R代表一个烷基团、一个烷氧基团或一个卤原子,m为零或1-3的整数,n为1-14的整数,条件是当m为2或3时,R可能相同也可能不同,当m为2且相邻的两个R为烷氧基团时,这两个烷氧基团的两个烷基部分可以结合形成与两个相邻的氧桥连接成员一起形成一个烷二氧基基团。这些衍生物通过用相应的苯甲酰卤酸酐对2'-脱氧-3',5'-双-O-烷基羰基-5-氟尿苷进行酰化制备,可作为抗肿瘤药物的活性成分,特别适用于口服给药。
