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
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.
这项发明涉及草酸酰胺抑制剂蛋白酪氨酸磷酸酶1B(PTP1B)和/或T细胞蛋白酪氨酸磷酸酶(TC-PTP)和/或蛋白酪氨酸磷酸酶(PTPases),在第48位具有天冬氨酸(Asp)(PTP1B编号,Chernoff等人,Proc Natl Acad Sci USA87: 2735-2789(1989)),以及通过将酶暴露于化合物11的抑制剂来抑制这些PTPases的方法。这项发明还涉及(I)设计和选择结合PTP1B和/或TC-PTP和/或在第48位具有天冬氨酸(Asp)的PTPases活性位点的抑制剂,(II)合成所述抑制剂,其制备方法和(III)包含抑制剂化合物的组合物。
