MAPK Kinase Inhibitor - Autophagy Inhibitor - MEK1 and MEK2 Inhibitor

U0126 is a selective inhibitor of MAP kinase kinases, MEK1 and MEK2 [1].

It acts by inhibiting the kinase activity of MEK1/2 thus preventing the activation of MAP kinases p42 and p44 which are encoded by the erk2 and erk1 genes respectively.

MAPK p42/p44 are involved in the signaling cascade triggered by LPS and other ligands through stimulation of the TLRs [2,3,4].

U0126 inhibits MEK1 and MEK2, and thus ERK activation. U0126 can be used to study the role of ERK, a MAPK involved in the induction of autophagy.
