Background: U0126 is a selective inhibitor of the mitogen-activated protein kinase kinases, MEK-1 and MEK-2, with a 100-fold higher potency than PD 98059. It is a weak inhbitor of PKC, Raf, ERK, JNK, MEKK, MKK-3, MKK-4/SEK, MKK-6, Abl, Cdk2 and Cdk4 and inhibits AP-1 transactivation in cell-based reporter assays.

Molecular weight: 380.5 g/mol
Chemical formula: C18H16N6S2
Solubility: Soluble in DMSO
Purity: >90%
CAS Number: 109511-58-2
