Abstract
Pyrrolo[2,1- c][1,4]benzodiazepine-β-glucuronide prodrugs 15a– b, with a potential for selective therapy of solid tumors by PMT and ADEPT have been designed, synthesized and evaluated for selective cytotoxicity in the presence of the enzyme β-glucuronidase. The prodrugs have been found to possess reduced cytotoxicity compared to the parent moieties, and are excellent substrates for the enzyme, exhibiting cytotoxicity selectively in the presence of the enzyme. Enhanced water solubility and improved stability are the other important outcomes upon modifying these molecules as their prodrugs.
