Inhibitors of Src Homology-2 Domain Containing Protein Tyrosine Phosphatase-2 (Shp2) Based on Oxindole Scaffolds
摘要:
Screening of the NCl diversity set of compounds has led to the identification of 5 (NSC-117199), which inhibits the protein tyrosine phosphatase (PTP) Shp2 with an IC(50) of 47 mu M. A focused library incorporating an isatin scaffold was designed and evaluated for inhibition of Shp2 and Shp1 PTP activities. Several compounds were identified that selectively inhibit Shp2 over ShpI and PTP1B with low to submicromolar activity. A model for the binding of the active compounds is proposed.

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.

Protein tyrosine phosphatase (PTP) Shp2 is a non-receptor PTP that involved in cell signaling and regulation of cell proliferation, differentiation, and migration. Shp2 mediates activation of kinases that are involved in the pathogenesis of human carcinoma. NSC-117199 was identified as a porent inhibitor of the protein tyrosine phosphatase (PTPa) Shp2. A focused library of analogs incorporating an isatin scaffold was designed and evaluated for inhibition of Shp2 and Shp1 PTP activities. Several compounds were identified that selectively inhibit Shp2 over Shp1 and PTP1B with low to sub-micromolar activity. Also disclosed are methods of inhibiting a protein tyrosine phosphatase in a cell and treating cancer through selective inhibition of Shp2.
