TYRPHOSTIN A25 Chemical Properties,Usage,Production
Chemical Properties
Yellow Green Powder
Uses
An inhibitor of epidermal growth factor receptor tyrosine kinase activity and has a reported IC50 of 15 μM for the autophosphorylation of the EGF-receptor.
Definition
ChEBI: 2-[(3,4,5-trihydroxyphenyl)methylidene]propanedinitrile is a benzenetriol.
General Description
A cell-permeable, reversible, and competitive inhibitor of substrate binding on protein tyrosine kinases. Inhibits epidermal growth factor receptor tyrosine kinase (IC50 = 3 μM) and the GTPase activity of transducin (IC50 = 7 μM). Blocks the induction of inducible nitric oxide synthase in glial cells. Induces apoptosis in human leukemic cell lines. Also reported to inhibit guanylyl cyclase.
Biological Activity
ag-82 is a cell-permeable, reversible, and competitive inhibitor of tyrosine kinase and epidermal growth factor (egf) receptor.protein tyrosine kinases (ptks) have been involved in regulating cell proliferation, cell differentiation, and signaling processes in the immune system. dysfunction of protein tyrosine kinases result in inflammatory responses and diseases including cancer, atherosclerosis, and psoriasis [2]. the epidermal growth factor receptor (egfr) is a transmembrane glycoprotein. activation of egfr results in autophosphorylation of receptor tyrosine kinase and has been involved in regulating cellular proliferation, differentiation, and survival. overexpression of egfr has been identified in a variety of tumor cell lines and has been associated with poor prognosis and decreased survival [3].in the human epidermoid carcinoma cell line a431, ag-82 inhibited the activity of epidermal growth factor receptor kinase with an ic50 value of 3 μm [1]. ag-82 inhibited the gtpase activity of transducin with an ic50 of 7 μm. ag-82 inhibited neuromedin b-induced phosphorylation of p125fak (focal adhesion kinase). ag-82 blocked the induction of inducible nitric oxide synthase in glial cells and induced apoptosis in human leukemic cell lines.
Biochem/physiol Actions
Cell permeable: yes
