Description: BI-78D3, also known as JNK Inhibitor X, is a potent JNK inhibitor. BI-78D3 dose-dependently inhibits the phosphorylation of JNK substrates both in vitro and in cell. BI-78D3 not only blocks JNK dependent Con A-induced liver damage but also restores insulin sensitivity in mouse models of type 2 diabetes.

Additional Information

JNK is a stress-activated protein kinase that modulates pathways implicated in a variety of disease states. JNK-interacting protein-1 (JIP1) is a scaffolding protein that enhances JNK signaling by creating a proximity effect between JNK and upstream kinases. A minimal peptide region derived from JIP1 is able to inhibit JNK activity both in vitro and in cell.
