corresponding data for the monomethyl derivative (V) and two other clinically tested members of this series of antineoplastic agents (dual antagonists), AB-100 (I) and AB-132 (II). The structures of the final hydrolysis products of III, IV, and V were determined and confirmed by direct synthesis. The results indicate that the mechanisms of hydrolysis of III, IV, and V (as that of the unsubstituted aziridine
合成了双(反式-2,3-二甲基叠氮基)膦基氨基甲酸酯(IV),并将其与相应的顺式2,3-二甲基衍生物(III)进行了比较。确定了这两种立体异构氮丙啶衍生物III和IV的比较烷基化活性和水解速率,并将其与该系列抗肿瘤药(双重拮抗剂)的单甲基衍生物(V)和其他两个经过临床测试的成员的相应数据进行比较, AB-100(I)和AB-132(II)。通过直接合成确定并证实了III,IV和V的最终水解产物的结构。结果表明,与2,2-二甲基氮丙啶类似物AB-的水解快得多相反,III,IV和V(未取代的氮丙啶衍生物AB-100的水解机理)基本上是SN2。 132,这涉及碳离子机制。这些研究为以下假设提供了进一步的支持:与该系列的其他成员相比,AB-132的独特药理特性可能与2,2-二甲基氮丙啶部分的独特化学特性有关。
