SU3327 is a potent, selective and substrate-competitive JNK inhibitor with an IC50 of 0.7 μM. SU3327 also inhibits protein-protein interactions between JNK and JNK Interacting Protein (JIP) with an IC50 of 239 nM. SU3327 shows less active against p38α and Akt kinase.

How to use

In Vitro:

SU3327 (compound 9) is able to inhibit TNF-α stimulated phosphorylation of c-Jun in HeLa cells (EC50 = 6.23 μM). SU3327 (25 nM) pretreatment of human-derived cerebral microvascular endothelial cells (hCMEC/D3) effectively reduces LPS-induced polymorphonuclear leukocytes (PMN) rolling/adhesion to hCMEC/D3, prevents activation of AP-1, and significantly reduces expression of VCAM-1.

In Vivo:

SU3327 (Compound 9; 25 mg/kg; intraperitoneal injection; male BKS.Cg-+Leprdb/+Leprdb/OlaHsd db/db mice) treatment possesses the ability to restore insulin sensitivity in mice models of diabetes. SU3327 (Compound 9) has favorable microsomal and plasma stability (T1/2 = 27 min).
