The invention provides prodrugs of DNA-reactive analogs of duocarmycin and CC-1065 anticancer agents, wherein a cyclic prodrug form, such as carbamate, thionocarbamate, or carbamimidate, can be hydrolyzed by the patient in vivo to yield a respective bioactive agent comprising a DNA-alkylating moiety and a binding/targeting moiety. The DNA-reactive moiety is a γ-spiro-cyclohexenone fused to a heterocyclyl group which can be produced by endogenous hydrolysis of a cyclic carbamate prodrug of the invention. The cyclic carbamate prodrug produces no residual byproduct during activation in vivo. Methods of synthesis and biological methods and data are also provided.
本发明提供了DNA反应性类似物duocarmycin和CC-1065抗癌剂的前药,其中循环前药形式,如氨基甲酸酯,硫代氨基甲酸酯或氨基甲酰亚胺,可以在体内被患者水解,生成相应的生物活性剂,包括DNA烷基化基团和结合/靶向基团。DNA反应性基团是γ-螺环己酮与杂环基团融合而成,可以通过本发明的循环氨基甲酸酯前药的内源性水解产生。循环氨基甲酸酯前药在体内激活时不产生残留副产品。本发明还提供了合成方法、生物学方法和数据。
