bearing advanced growing P388 tumors were carried out. IAP was significantly more cytotoxic in-vitro than SUM-IAP, but the antitumor activity of SUM-IAP was by order of magnitude higher than the antitumor activity of IAP. The reason for these findings is discussed with respect to the enzymatic cleavage of the various I-aldophosphamide derivatives to the corresponding isophosphoramide mustards and 3-hydroxypropanal
本工作研究了不同的异磷酰胺芥末引起的不同DNA损伤对使用I-醛磷酰胺-过氢噻嗪(IAP)和甲磺酰基-I-醛磷酰胺-过氢噻嗪(oxazaphosphorine-perhydrothiazine)(SUM-IAP)产生的氧杂氮磷细胞抑制剂的3-羟基丙醛辅助抗凋亡抗肿瘤活性的影响用于体外和体内实验。IAP和SUM-IAP自发水解为相应的I-醛磷酸酰胺衍生物。它们的烷基化部分的化学结构不同,而IAP在SUM-IAP分子中具有两个氯乙基,一个氯乙基被甲磺酰基取代。使用这两种物质,进行了对P388肿瘤细胞的体外细胞毒性研究以及对患有晚期P388肿瘤的小鼠的治疗实验。与SUM-IAP相比,IAP的体外细胞毒性明显更高,但是SUM-IAP的抗肿瘤活性比IAP的抗肿瘤活性高几个数量级。关于各种I-醛基磷酰胺衍生物的酶促裂解为相应的异磷酰胺芥子和3-羟基丙醛的讨论了这些发现的原因。总的来说,这些发现表明,通过
