Application

Phenylhydrazono pyrazolone sulfonate 1 (PHPS1) sodium salt hydrate has been used as a protein-tyrosine phosphatase (shp2) inhibitor to study its effects on bisphenol A (BPA) and nonyl phenol (NP)-induced cell proliferation of MCF7 cell. It has also been used as a shp2 inhibitor to study its pro-atherosclerotic or atheroprotective effect in vivo and in vitro.

Biochem/physiol Actions

Phenylhydrazono pyrazolone sulfonate 1 (PHPS1) represses E2-induced gene transcription and rapid DNA synthesis. It also blocks mitogen-activated protein kinase (ERK1/2) activation and reduces the cigarette smoke induced-inflammatory response in mouse lungs.
Shp-2 is a Src Homology-2 (SH2) containing phosphatase that regulates growth factor signalling. The enzyme is expressed ubiquitously in mammalian tissues and plays essential roles in development. It is also implicated in various pathological states. PHPS1 is a selective inhibitor of Shp-2 and blocks Shp-2 dependent downstream signalling.
