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.

Inhibits ERK1, MKK3/p38, MKK4, JNK, and PKC activities only at higher concentrations (IC50 >10 µM). Reported to exhibit neuroprotective effects against ischemic brain injury in mice by selectively blocking ERK1/2 activation (i.e. noncompetitive with respect to ATP).

Human Kinome & InhibitorSelect™ Libraries

Human Kinome Poster: The InhibitorSelect™ Protein Kinase Inhibitor Libraries provide broad coverage of the human kinome as shown here. The depicted human kinome dendrogram of 518 kinases are classified into five broad groups, 90 families, and 145 subfamilies. Inhibitor coverage was assigned based upon published data related to potency (IC50, EC50, Kd, etc.) for individual kinases harvested from the literature. Colored dots denote which library contains an inhibitor with demonstrated potent activity against the designated kinase and do not necessarily reflect known specificity of the inhibitor. Coverage of lipid and atypical kinases are depicted as a separate dendrogram. As shown, Calbiochem® Protein Kinase Inhibitor Libraries cover all major kinase families including TK, CMGC, CAMK, AGC, CK1, STE, TKL, as well as Lipid or Atypical kinase families.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
