Compound class: Synthetic organic
Comment: SP600125 is an ATP-competitive, pan JNK inhibitor with potent activity against JNK1, JNK2 and JNK3 [2]. Off targets including the aryl hydrocarbon receptor (AhR; agonist) [5], Mps1 (TTK, a tyrosine, serine and threonine kinase) [6], and some serine/threonine kinases (Aurora kinase A, FLT3, MELK, and TRKA) [3] have been identified.
