hydrolysis kinetics of a series of N-Mannich bases of carboxamides, thioamides, and other NH-acidic compounds were studied to assess their suitability as prodrugs for various drugs. The pH-rate profiles for the compounds were determined at 37 degrees and were accounted for by assuming the spontaneous decomposition of both free and protonated Mannichbases. The reaction rate for the free base increased
