ABSTRACT:
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.
