Chemical. CAS 129-56-6. Formula C14H8N2O. MW 220.2. SP600125 is an orally active, reversible and ATP-competitive broad-spectrum JNK inhibitor for JNK1, JNK2 and JNK3 IC50 = 40nM, 40nM and 90nM, respectively. In Jurkat T cells, SP600125 suppressed the phosphorylation of c-Jun with IC50 of 5-10 µM. It has 10-fold greater selectivity against MKK4, 25-fold greater selectivity against MKK3, MKK6, PKB and PKCalpha, and 100-fold selectivity against ERK2, p38, Chk1, EGFR. SP600125 is also a broad-spectrum inhibitor of serine/threonine kinases including hydrocarbon receptor AhR, Mps1, Aurora kinase A, FLT3 and TRKA. SP600125 inhibits cell cycle, autophagy and ferroptosis and activates apoptosis. It shows anti-inflammatory activity by inhibiting the expression of inflammatory genes such as COX-2, IL-2 IFN-gamma and TNF-alpha and has antiviral and neuroprotective properties.
