General description

A cell-permeable vinylogous cyanamide that acts as a selective inhibitor of MEK1/2 (IC50 = 180 nM and 220 nM, respectively). Shown to inhibit AP-1 activity (IC50 = 2.03 µM). Inhibits ERK1, MKK3/p38, MKK4, JNK, and PKC activities at higher concentrations (IC50 >10 µM). Reported to offer neuroprotection against ischemic brain injury in mice by selectively blocking ERK1/2 activation. Also suppresses IL-1β expression. Displays enhanced aqueous solubility compared to U0126 (Cat. No. 662005). Uncompetitive with respect to ATP.
