The present invention relates to non-phosphorus containing O-malonyltyrosyl compounds, derivatives thereof, uses of the O-malonyltyrosyl compounds in the synthesis of peptides, and O-malonyltyrosyl compound-containing peptides. The O-malonyltyrosyl malonyltyrosyl compounds and O-malonyltyrosyl compound-containing peptides of the present invention are uniquely stable to phosphotases, capable of crossing cell membranes, suitable for application to peptide synthesis of O-malonyltyrosyl compound-containing peptides, and amenable to prodrag derivatization for delivery into cells. The present invention also provides for O-malonyltyrosyl compound-containing peptides which exhibit inhibitory potency against binding interactions of receptor domains with phosphotyrosyl-containing peptide ligands. |
