产品描述:
Tyrphostins are tyrosine phosphorylation inhibitors that act by inhibiting tyrosine kinases.{15153} AG957 is a tyrphostin that targets transforming Bcr-Abl fusion proteins (p185Bcr-Abl, p210Bcr-Abl), as well as normal c-Abl (IC50s = 4.3, 1, and 7.1 µM, respectively, for human proteins).{29184} It also inhibits epidermal growth factor receptor (IC50 = 0.25 µM).{29184} 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.{29187,29186} AG957 is also used to study signaling through c-Abl.{29185}
