Biological Activity

[Description]:

Tyrphostin A9(AG 17), a tyrosine kinase inhibitor, is a potent inducer of mitochondrial fission. Tyrphostin A9 emerged as the most potent and selective of 51 tyrosine kinase inhibitors tested against the TNF-induced respiratory burst. IC50 value: Target: Multi tyrosine kinaseTyrphostin A9 inhibited TNF-induced tyrosine phosphorylation of pyk2 without blocking the cells' bactericidal activity. Tyrphostin A9 is a PDGF receptor tyrosine kinase inhibitor (IC50 = 500 nM). Recent findings suggest that signaling via PDGF receptor tyrosine kinases is not necessary for the shift of the smooth muscle cells from a contractile to a synthetic phenotype. On the other hand these enzymes apparently carry out important functions in the control of intracellular membrane traffic and cell division.
