General description

A potent and specific inhibitor of MEK1 (IC50 = 72 nM) and MEK2 (IC50 = 58 nM). The inhibition is noncompetitive with respect to both ATP and ERK. Has very little effect on other kinases such as Abl, Cdk2, Cdk4, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, PKC, and Raf. Shown to block doxazosin-induced osteoblastic differentiation. Also acts as an immunosuppressant by effectively blocking IL-2 synthesis and T cell proliferation without affecting the long-term outcomes of either T cell activation or tolerance. Noncompetitive with respect to ATP. Also available in InSolution format (Cat. No. 662009).
