    Abstract: The composition, methods of synthesis, and applications of a new class of tumor selective antineoplastic drugs is described. These novel antineoplastic agents are of the general structure: A-C-B. The agents are designed with two key functionalities: a trigger which toxifies the drug; (A) and a deactivator which detoxifies the drug (B) The trigger is selected such that it is activated by an enzyme which is present in elevated levels in the tumor. The deactivator is selected such that it is actuated by an enzyme ubiquitous to all tissues. The fate of the drug in a given cell is then determined by the ratio of the enzymatic activity that triggers toxication to the enzymatic activity which detoxifies the drug. The partitioning of the drug between toxic metabolite and nontoxic metabolite defines the resulting specificity of cytotoxic effect.
