Abstract: The composition, synthesis, and applications of tumor associated protease activated prodrugs of phosphoramide mustard, isophosphoramide mustard and analogs with detoxification functionalities are described. These drugs release a cytotoxic phosphoramide mustard analog following activation by tumor associated proteases and esterases. The general structure for these drugs is: ##STR1## Wherein R1 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; wherein X is a good leaving group such as a halogen; R2 is a beta-X-ethyl-amino group which may optionally bear substituents on the nitrogen or carbon atoms; or an amino group (NH.sub.2) which may optionally be substituted. Wherein A is a benzyloxy derivative with one or more acyloxy or acylamino groups in para or ortho portions relative to the phosphoester; and wherein the acyloxy or acylamino groups are not (substituted or unsubstituted) p-guanidino-benzoyloxy groups or p-guanidino-benzoylamino groups.

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.
