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-spirocyclohexenone 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.
该发明提供了DNA-反应性类似物duocarmycin和CC-1065抗癌药物的前药,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酸酰胺,可以在体内被患者水解,产生包含DNA烷基化基团和结合/靶向基团的生物活性剂。DNA-反应性基团是与异环丙环己酮融合的杂环基团,可以通过该发明的循环氨基甲酸酯前药的内源水解产生。在体内激活过程中,循环氨基甲酸酯前药不产生任何残留副产物。还提供了合成方法和生物学方法和数据。
