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.
本发明公开了将含有胺、酰胺、
胍、异
脲、异
硫脲和双胍官能团的碱性氮杂药物化合物进行N-
磷酸化,以产生增强
水溶性或脂溶性,或减少毒性的前药。这些前药可将药物转化为前药。在体内,这些前药会被
水解,释放出
磷酸盐并再生原始药物。
