Compounds and associated methods for inhibiting a protein tyrosine phosphatase. By a combination of experimental and virtual screenings of the NCI Diversity Set chemical library, NSC-87877 and NSC-117199 have been identified as Shp2 PTP inhibitors. Significantly, NSC-87877 is active in cell-based assays and has no detectable off-target effects in the EGF-stimulated Erk1/2 activation pathway. Additionally, a number of analogs of NSC-117199 have been produced. These analogs exhibit enhanced protein tyrosine phosphatase inhibition and are found to be potent and/or selective inhibitors of Shp1 and/or Shp2 protein tyrosine phosphatases.

Significantly, NSC-87877 is active in cell-based assays and has no detectable off-target effects in the EGF-stimulated Erkl/2 activation pathway. Additionally, a number of analogs of NSC-1 17199 have been produced. These analogs exhibit enhanced protein tyrosine phosphatase inhibition and arc found to be potent and/or selectiv e inhibitors of Shp l and/or Shp2 protein tyrosine phosphatases. [FR] La présente invention concerne des composés et des procédés associés permettant d'inhiber une protéine tyrosine phosphatase. Grâce à une association de criblages expérimentaux et virtuels de la banque chimique Diversity Set du NCI, on a pu identifier le NSC-87877 et le NSC-117199 comme inhibiteurs du Shp2 PTP. De manière significative, le NSC-87877 est actif dans des analyses cellulaires et ne présente aucun effet non ciblé détectable dans la voie d'activation Erkl/2 stimulée par EGF. En outre, un certain nombre d'analogues du NSC-1 17199 ont été produits. Ces analogues présentent une inhibition accrue de la protéine tyrosine phosphatase et sont des inhibiteurs puissants et/ou sélectifs des protéines tyrosines phosphatases Shpl et/ou Shp2.
