Catalytic antibodies for carbamate activation by a non-spontaneous reaction mechanism

摘要

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.
