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, quanidine, 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.
本发明揭示了将含有胺基、酰胺基、瓜妥啶基、异尿素基、异硫脲基和双胍基功能的药物化合物进行N-磷酸化,以产生增强水溶性或脂溶性、或降低毒性的前药。这些前药在体内水解,释放出磷酸盐,再生出原始药物。
