SP600125 | 1669

Cell-permeable. A selective inhibitor of c-Jun N-terminal kinase (JNK). Competitively and reversibly inhibits JNK1, 2 and 3 (IC₅₀ = 40-90 nM) with negligible activity at ERK2, p38β and a range of enzymes (IC₅₀ > 10 µM).

U0126 is a potent and selective non-competitive inhibitor of MAP kinase kinase(MEK). Inhibits MEK-1 and MEK-2 (IC₅₀ values of 0.07 and 0.06 µM respectively) with little or no effect on the activities of PKC, Abl, Raf, MEKK, ERK, JNK, MKK-3, MKK-4/SEK, MKK-6, Cdk2 or Cdk4.
