Method of inhibiting PTP 1B and /or T-cell PTP and/or other PTPases with an Asp residue at position 48

摘要

This invention relates to oxalylamide inhibitors of Protein Tyrosine Phosphatase 1B (PTP1B) and/or T-cell Protein Tyrosine Phosphatase (TC-PTP) and/or Protein Tyrosine Phosphatases (PTPases) having an aspartic acid (Asp) in position 48 (PTP1B numbering, Chernoff et al, Proc Natl Acad Sci USA 87: 2735-2789 (1989)) and a method of inhibiting such PTPases by exposing the enzyme to inhibitor compounds of formula 1 This invention also relates to (I) the design and selection of inhibitors, which bind to the active site of PTP1B and/or TC-PTP and/or PTPases having an aspartic acid (Asp) in position 48 (II) the synthesis of said inhibitors, methods for their preparation and (III) to compositions comprising the inhibitor compounds.
