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.
具有催化活性的
抗体,能够催化激活含有羰酸酯(-O-CO-NH-)的前药,适用于
抗体导向的酶
