AG 957 Usage And Synthesis

Description

Tyrphostins are tyrosine phosphorylation inhibitors that act by inhibiting tyrosine kinases. AG957 is a tyrphostin that targets transforming Bcr-Abl fusion proteins (p185^Bcr-Abl, p210^Bcr-Abl), as well as normal c-Abl (IC₅₀s = 4.3, 1, and 7.1 μM, respectively, for human proteins). It also inhibits epidermal growth factor receptor (IC₅₀ = 0.25 μM). As the constitutively-active 210 kDa Bcr-Abl fusion protein commonly occurs in chronic myelogenous leukemia (CML) cells, AG957 is commonly used to study Bcr-Abl signaling in the CML K562 cell line. AG957 is also used to study signaling through c-Abl.

Uses

Tyrphostin AG 957 is a potent tyrosine kinase inhibitor. Also, it causes metabolic alterations in K562 cells. It is a COVID19-related research product.

Definition

ChEBI: 4-[(2,5-dihydroxyphenyl)methylamino]benzoic acid methyl ester is an aromatic amine.
