ABSTRACT:
The N-phosphorylation of basic nitrogenous drug compounds to produce pro-drugs with enhanced water solubility or lipid solubility, or reduced toxicity, is disclosed. Drugs containing amine, amidine, guanidine, isourea, isothiourea and biguanide functions may be converted to such pro-drugs. The pro-drugs are hydrolyzed in the body, regenerating the original drugs with the release of a salt of phosphoric acid.
