in trimethyl phosphate yielded the phosphorodichloridate 5, which was subsequently reacted with aziridine, or 2,2-dimethylaziridine to give compounds 6 and 7, respectively. The 2,2-dimethylaziridine derivative 7 was considerably more active than 6 against leukemia L1210 and P-388 in mice but less active than the previously synthesized, simpler phosphinate derivatives 2 and 3. It appears that the thymidine
3′-乙酰基胸苷与三氯氧磷在磷酸三甲酯中的反应产生二氯化磷,其随后与氮丙啶或2,2-二甲基氮丙啶反应,分别得到化合物6和7。2,2-二甲基氮丙啶衍生物7对小鼠的L1210和P-388白血病的活性明显高于6,但比以前合成的简单次膦酸酯衍生物2和3的活性低。看来胸苷部分不能使这些化合物利用细胞的核苷转运机制,也不能通过干扰2,2-二甲基氮丙啶类似物与胆碱酯酶的结合来增加其选择性。化合物7强烈抑制马血清胆碱酯酶,而化合物6无活性。
