MAP Kinase Inhibitor - Autophagy Inhibitor - JNK inhibitor

SP600125 is a potent, cell-permeable, selective and reversible inhibitor of c-Jun N-terminal kinase (JNK) [1].

It inhibits in a dose-dependent manner the phosphorylation of JNK. JNK is a member of the mitogen-activated protein kinase (MAPK) family and plays an essential role in TLR mediated inflammatory responses [2, 3].

Inhibition of JNK activity by SP600125 is usually associated with downregulation of Beclin-1 and reduced autophagy.
