Background: Tyrphostin AG 957 is a a potent tyrosine kinase inhibitor which selectively blocks the tyrosine kinase activity of human bcr-abl (Ki ~ 750 nM) over c-abl (Ki ~ 10 µM). It also decreases bcr-abl phosphorylation in viable K562 cells at concentrations and durations of exposure that also inhibit cell proliferation. It has been reported to alter the physical state of bcr-abl and the association of bcr-abl with Shc and Grb2 in K562 cells.
