MEK Inhibitor I-CAS 297744-42-4-Calbiochemv

C₂₁H₁₈N₄OS

374.46

A cell-permeable, potent, and selective inhibitor of MEK (IC₅₀ = 12 nM) with little activity towards MKK3 and MKK4 (IC₅₀ >1 µM). The inhibition is non-competitive with respect to ERK and the compound displays significant affinity only towards ATP-bound MEK (i.e. non-competitive with respect to ATP). Exhibits superior potency, solubility, and stability compared to U0126 (Cat. No. 662005) in aqueous solutions. Shown to protect against phorbol ester-mediated ear edema in mice (ED₅₀ of 5 mg/kg, ip.).
