General description

A potent, cell-permeable, reversible, and ATP-competitive Src family kinase inhibitor. Inhibits Src (IC50 = 280 nM) as well as closely related kinases such as Fyn (IC50 = 170 nM) and Yes (IC50 = 20 nM) and Lyn (IC50 = 130 nM). Acts as a weak inhibitor of Lck (IC50 = 688 µM) and PDGF receptor kinase (IC50 >10 µM). A 10 mM (500 µg/135 µl) solution of SU6656 (Cat. No. 572636) in DMSO is also available.
A potent, cell-permeable, reversible, and ATP-competitive inhibitor of Src-family protein tyrosine kinases. Inhibits Src (IC50 = 280 nM) as well as closely related kinases Fyn (IC50 = 170 nM), Yes (IC50 = 20 nM) and Lyn (IC50 = 130 nM). The inhibition is competitive with respect to ATP. Has only a trivial effect on Lck (IC50 = 6.88 µM). Does not affect the activity of PDGF-β receptor kinase (IC50 ≥10 µM) and IGF-1 receptor kinase (IC50 ≥20 µM).

Plasma membrane damage and cell death during processes such as necroptosis and apoptosis result from cues originating intracellularly. However, death caused by pore-forming agents, like bacterial toxins or complement, is due to direct external injury to the plasma membrane. To
