The synthesis of three novel prodrugs, 4-[bis[2-(mesyloxy)ethyl]amino]benzoyl-L-glutamic acid (7), 4-[(2-chloroethyl)[2-(mesyloxy)ethyl]amino]benzoyl-L-glutamic acid (8), and 4-[bis(2-chloroethyl)amino]benzoyl-L-glutamic acid (9), for use as anticancer agents, is described here. Each is a bifunctional alkylating agent in which the activating effect of the ionized carboxyl function is masked through
三种新型前药的合成[4- [双[2-(甲氧基氧基)乙基]氨基]苯甲酰基-L-谷氨酸(7),4-[(2-氯乙基)[2-(甲氧基氧基乙基)]氨基]苯甲酰基这里描述了用作抗癌剂的-L-谷氨酸(8)和4- [双(2-氯乙基)氨基]苯甲酰基-L-谷氨酸(9)。每种都是双官能烷基化剂,其中离子化羧基官能团的活化作用通过与谷氨酸残基的酰胺键掩盖。这些相对无活性的前药被设计为通过预先施用与细菌羧肽酶G2(CPG2)偶联的单克隆抗体,在肿瘤部位被活化为它们相应的氮烷基化剂(分别为10、11和12)。在CPG2存在的情况下,用每种前药监测两种不同肿瘤细胞系的生存力。
