Novel 2'-deoxy-5-substituted uridine derivative represented by the general formula, ##STR1## wherein R.sub.1 is a hydrogen atom, a benzoyl group or a tetrahydrofuranyl group; R.sub.2 is a fluorine atom or a trifluoromethyl group; and any one of R.sub.3 and R.sub.4 is a hydrogen atom and the other one is an alkyl group having 1 to 10 carbon atoms, an alkenyl group having 2 to 6 carbon atoms, a benzyl group having as the substituents selected from the group consisting of a halogen atom, an alkyl group having 1 to 4 carbon atoms, an alkoxy group having 1 to 4 carbon atoms and a nitro group, or an alkyl group having 1 to 3 carbon atoms having one or two phenyl groups as the substituents. The novel 2'-deoxy-5-substituteduridine derivative possesses excellent antitumor activity with less toxicity, thus it is useful as antitumor agent.
由一般公式表示的新型2'-脱氧-5-取代尿苷衍生物,其中R.sub.1是氢原子、苯甲酰基或四氢呋喃基;R.sub.2是氟原子或三氟甲基基团;R.sub.3和R.sub.4中的任意一个是氢原子,另一个是具有1至10个碳原子的烷基基团、具有2至6个碳原子的烯基基团、苄基基团,其取代基被选择自卤素原子、具有1至4个碳原子的烷基基团、具有1至4个碳原子的烷氧基团和硝基基团的群组,或具有一个或两个苯基取代基的具有1至3个碳原子的烷基基团。这种新型2'-脱氧-5-取代尿苷衍生物具有出色的抗肿瘤活性且毒性较低,因此可用作抗肿瘤剂。
