and hydrolysis with a t1/2 = 44 min. A highly potent and selectiveinhibitor of protein tyrosine phosphatase 1B (PTP1B) with a nanomolar Ki has been reported, but this bis(difluoromethylphosphonate) lacks potential utility due to its exceedingly low membrane permeability at physiological pH. A prodrug of this inhibitor has been synthesized and evaluated in a cell-based assay. The prodrug exhibits nanomolar

described. Specifically, we have developed phosphoramidate prodrugs of the anticancer nucleotide 5-fluoro-2'-deoxyuridine-5'monophosphate (FdUMP). These phosphoramidate prodrugs contain an ester group that undergoes intracellular activation liberating phosphoramidate anion, which undergoes spontaneous cyclization and P-N bond cleavage to yield the nucleoside monophosphate quantitatively. In vitro evaluation
Novel phosphoramidate derivatives of hydroxy functional or amino functional compounds, including amino acids, peptides, peptidomimetics and nucleotide analogs, are described. The compounds enable enhanced intracellular delivery of drugs as their corresponding phosphate esters or amides. Described phosphoramidate compounds exhibit antiproliferative activity. Pharmaceutical formulations are provided for treatment of cancers.
