A nucleotide derivative represented by the general formula: ##STR1## wherein R represents an acyl group having 14 - 22 carbon atoms and having an aliphatic acyl moiety; X represents a hydrogen atom, a halogen atom, an alkyl group having 1 - 4 carbon atoms, or a trifluoromethyl group; and at least one, but not all, of Y.sub.1, Y.sub.2, and Y.sub.3 represents a phosphate, a pyrophosphate, a triphosphate, or a salt thereof, the balance of Y.sub.1, Y.sub.2 and Y.sub.3 representing a hydroxyl group; or in case of ribosyl, Y.sub.1 and Y.sub.3, or Y.sub.2 and Y.sub.3 represent, at the same time, the aforesaid phosphate, pyrophosphate, triphosphate or salt thereof and the remaining group of Y.sub.1, Y.sub.2 or Y.sub.3 represents a hydroxyl group; or in case of arabinosyl, Y.sub.1 and Y.sub.2, or Y.sub.2 and Y.sub.3 represent, at the same time, the aforesaid phosphate, pyrophosphate, triphosphate or salt therof and the remaining group of Y.sub.1, Y.sub.2 or Y.sub.3 represents a hydroxyl group. The nontoxic salts of these phosphates are useful as an antileukemialagent for mice which is soluble in water and has high stability.
一种核苷酸衍生物,其通式表示为:##STR1##其中R代表含有14-22个碳原子的酰基团,具有脂肪族酰基基团;X代表氢原子、卤素原子、含有1-4个碳原子的烷基基团或三氟甲基基团;Y.sub.1、Y.sub.2和Y.sub.3中至少一个但不是全部代表磷酸盐、焦磷酸盐、三磷酸盐或其盐,Y.sub.1、Y.sub.2和Y.sub.3的余下部分代表羟基;在核糖基的情况下,Y.sub.1和Y.sub.3,或Y.sub.2和Y.sub.3同时代表上述磷酸盐、焦磷酸盐、三磷酸盐或其盐,Y.sub.1、Y.sub.2或Y.sub.3的剩余基团代表羟基;在阿拉伯糖基的情况下,Y.sub.1和Y.sub.2,或Y.sub.2和Y.sub.3同时代表上述磷酸盐、焦磷酸盐、三磷酸盐或其盐,Y.sub.1、Y.sub.2或Y.sub.3的剩余基团代表羟基。这些磷酸盐的无毒盐对小鼠具有抗白血病作用,可溶于水且具有高稳定性。
