NSC87877 phosphatase inhibitor

Cat.No.S8182

NSC-87877 is a cell-permeable inhibitor of both SHP-1 and SHP-2 with IC50 values of 355 and 318 nM respectively. It also inhibits EGF-induced Erk1/2 activation in HEK293 cells and significantly reduces MDA-MB-468 cell viability/proliferation.

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such
as vortex, ultrasound or hot water bath can be used to aid dissolving.

In vitro
NSC-87877 seems to have no selectivity between human Shp2 and Shp1 in vitro. NSC-87877 inhibits EGF-stimulated Shp2 activation and EGF-induced Erk1/2 activation. NSC-87877 suppresses Erk1/2 activation by a Gab1-Shp2 chimera but does not affect PMA(phorbol 12-myristate 13-acetate)-induced Erk1/2 Activation. NSC-87877 does not inhibit EGF-induced Gab1 tyrosine phosphorylation and Gab1-Shp2 association. NSC-87877 can significantly reduce MDA-MB-468 cell viability/proliferation, especially in combination with a phosphoinositide 3-kinase inhibitor[1].
In vivo
NSC-87877 almost completely prevented EAE(experimental autoimmune encephalomyelitis) development by blocking the accumulation of inflammatory cells in the CNS(central nervous system)[2]. In an intrarenal mouse model of neuroblastoma, NSC-87877 treatment results in decreased tumor growth and increased p53 and p38 activity[3]. Intrathecal administration of NSC-87877 (an SHP2 antagonist; 1, 10, or 100 μM/rat) into the allodynic rats suppresses spinal nerve ligation-induced allodynia, spinal SHP2 and NR2B phosphorylation, and SHP2/phosphorylated SHP2-PSD-95 and PSD-95-NR2B/phosphorylated NR2B coprecipitation[4].
