ORALLY ABSORBED DRUGS

摘要

Orally nonabsorbed or poorly absorbed drugs may be converted to orally absorbed prodrug derivatives by derivatization of free functional groups selected from amino, hydroxyl, mercapto, phosphate and/or carboxyl with groups sensitive to mild basic conditions such as 9-fluorenylmethoxycarbonyl (Fmoc), 2-sulfo-9-fluorenylmethoxycarbonyl (Fms), and fluorenylmethyl (Fm).
