The present invention provides a pyrimidine nucleoside compound represented by the following formula (1):
[wherein one of X and Y is cyano and the other is hydrogen; and i) R
1
is hydrogen, and R
2
is alkyloxycarbonyl wherein the alkyl moiety is straight or branched C
5-12
alkyl (the alkyl may be substituted), or alternatively, ii) R
1
is alkyloxycarbonyl wherein the alkyl moiety is straight or branched C
9
alkyl or alkenyloxycarbonyl wherein the alkenyl moiety is straight or branched C
9
alkenyl, and R
2
is hydrogen] or a salt thereof. The pyrimidine nucleoside compound or a salt thereof of the present invention shows a higher antitumor effect than existing pyrimidine nucleoside compounds.
本发明提供了一种嘧啶核苷化合物,其由以下式子(1)表示:[其中X和Y中的一个是氰基,另一个是氢原子;i)R1为氢原子,R2为烷氧羰基,其中烷基是直链或支链C5-12烷基(烷基可以被取代),或者,ii)R1为烷氧羰基,其中烷基是直链或支链C9烷基或烯基氧羰基,其中烯基是直链或支链C9烯基,R2为氢原子]或其盐。本发明的嘧啶核苷化合物或其盐比现有的嘧啶核苷化合物具有更高的抗肿瘤效果。
