Catalytic antibodies capable of catalysing activation of a carbamate (-O-CO-NH-) containing prodrug suitable for Antibody Directed Abzyme Prodrug Therapy (ADAPT) by catalysing breakdown of the prodrug at the carbamate position by a non-spontaneous reaction mechanism. The non-spontaneous reaction preferably has a BAc2 mechanism and the prodrug is a preferably a nitrogen mustard aryl carbamate. The invention also includes relevant immunogens, screens for catalytic activity using short transition state analogues and ADAPT systems.
催化抗体能够通过非自发反应机制催化氨基甲酸酯位上的原药分解,从而活化适用于抗体引导的阿比西尼亚酶原药疗法(ADAPT)的含有氨基甲酸酯(-O-CO-NH-)的原药。非自发反应机制最好是 BAc2,原药最好是氮芥芳基氨基甲酸酯。本发明还包括相关的免疫原、使用短过渡态类似物的催化活性筛选和 ADAPT 系统。
