Peptidic α-Ketocarboxylic Acids and Sulfonamides as Inhibitors of Protein Tyrosine Phosphatases
摘要:
One common approach for designing protein tyrosine phosphatase (PTPase) inhibitors is to incorporate a nonhydrolyzable phosphotyrosine (pTyr) mimic into a peptide substrate for PTPases. This report describes the synthesis of three such nonhydrolyzable pTyr mimics that contain alpha-ketoacid, alpha-hydroxyacid, and methylenesulfonamide functional groups in place of the phosphate. These pTyr mimics were incorporated into the peptide sequence Ac-Asp-Ala-Asp-Glu-X-Leu-NH2, where X is the pTyr mimic, and analyzed for activity against the Yersinia PTPase and PTP1B.
