What is AG 18?
Chemical properties
Yellow Powder
The Uses of AG 18
AG 18 inhibits EGFR with IC50 of 35 μM.
The Uses of AG 18
A specific inhibitor for the epidermal growth factor receptor. Also inhibits EGF-dependent cell proliferation (IC50=35uM).
Definition
ChEBI: 2-[(3,4-dihydroxyphenyl)methylidene]propanedinitrile is a member of catechols.
What are the applications of Application
Tyrphostin A23 is an agent that blocks EGF-dependent autophosphorylation
Biological Activity
Inhibitor of epidermal growth factor receptor (EGFR) and platelet-derived growth factor receptor (PDGFR) kinase (IC 50 values are 35 and 25 μ M respectively). Inhibits EGF-stimulated cell proliferation. Also acts as a mitochondrial uncoupler that alters phosphorylation-dependent cell signaling.
Biochem/physiol Actions
Tyrphostin 23 is a small molecule inhibitor of epidermal growth factor (EGF) receptor kinase function. This molecule associates with the substrate subsite of the protein tyrosine kinase (PTK) domain,.
