an oxycarbonyl or a carbamoyl bond to a glutamic acid. These prodrugs were designed to be activated to their corresponding phenol and aniline nitrogen mustard drugs at a tumor site by prior administration of a monoclonal antibody conjugated to the bacterial enzyme carboxypeptidase G2 (CPG2) in antibody-directed enzyme prodrug therapy (ADEPT). The synthesis of the analogous novel parent drugs (2a-r) is
设计了十六种衍生自苯酚或苯胺芥子气的新型潜在前药及其具有环取代和/或不同烷基化功能的16种相应药物。[[[4-]双(2-溴乙基)-(1a),[[[4- [双(2-碘乙基)-(1b)和[[4-[(2-氯乙基)-[2] -(甲甲氧基)乙基]氨基]苯基]氧基]羰基] -L-谷氨酸(1c),其[[[2-和3-取代的-4- [双(2-氯乙基)氨基]苯基]氧基]羰基合成了] -L-谷氨酸(1e-1)和[[3-取代-4- [双(2-氯乙基)氨基]苯基]氨基甲酰基] -L-谷氨酸(1o-r)。它们是双官能烷基化剂,其中酚羟基或氨基官能团的活化作用通过与羰基氨酸的氧羰基或氨基甲酰基键被掩盖。通过在抗体导向的酶前药治疗(ADEPT)中预先施用与细菌羧肽酶G2(CPG2)偶联的单克隆抗体,可以将这些前药设计为在肿瘤部位被激活为相应的苯酚和苯胺氮芥子气药物。还描述了类似的新型母体药物(2a-r)的合成。用潜在的前
