BI-78D3 is a substrate competitive inhibitor of JNK inhibitor [2].
JNK is a member of the MAPK family. JNK is a stress-activated protein kinase that modulates pathways implicated in a variety of disease states. Non-motoric JNK functions may differ between cell types and organs. The JNK is involved in a1-adrenoceptor-mediated contraction of prostate smooth muscle. For non-malignant, epithelial human prostate cells, JNK activation not only has the function of pro-apoptotic and antiproliferative but also related with JNK-dependent survival.[1]
BI-78D3 is competitive with ATF2 for binding to JNK1 with an apparent Ki value of 200 nM. In addition, it has been reported that BI-78D3 does not inhibit the phosphorylation of a short peptide substrate lacking a D-domain. This confirms that BI-78D3 is substrate competitive.[2]
BI-78D3 inhibits both noradrenaline- and phenylephrine-induced contractions. Then it prevents α1-adrenoceptor-mediated contraction of prostate tissue. As an effective JNK inhibitor, BI-78D3 has the ability of abrogating ConA-induced liver damage and restoring insulin sensitivity. [1,2]

Inhibition of adrenergic human prostate smooth muscle contraction by the inhibitors of c-Jun N-terminal kinase, SP600125 and BI-78D3.[Pubmed:22364229]
Br J Pharmacol. 2012 Jul;166(6):1926-35.
BACKGROUND AND PURPOSE alpha(1) -Adrenoceptor-induced contraction of prostate smooth muscle is mediated by calcium- and Rho kinase-dependent mechanisms. In addition, other mechanisms, such as activation of c-jun N-terminal kinase (JNK) may be involved. Here, we investigated whether JNK participates in alpha(1)-adrenoceptor-induced contraction of human prostate smooth muscle. EXPERIMENTAL APPROACH Prostate tissue was obtained from patients undergoing radical prostatectomy. Effects of the JNK inhibitors SP600125 (50 microM) and BI-78D3 (30 microM) on contractions induced by phenylephrine, noradrenaline and electric field stimulation (EFS) were studied in myographic measurements. JNK activation by noradrenaline (30 microM) and phenylephrine (10 microM), and the effects of JNK inhibitors of c-Jun phosphorylation were assessed by Western blot analyses with phospho-specific antibodies. Expression of JNK was studied by immunohistochemistry and fluorescence double staining. KEY RESULTS The JNK inhibitors SP600125 and BI-78D3 reduced phenylephrine- and noradrenaline-induced contractions of human prostate strips. In addition, SP600125 reduced EFS-induced contraction of prostate strips. Stimulation of prostate tissue with noradrenaline or phenylephrine in vitro resulted in activation of JNK. Incubation of prostate tissue with SP600125 or BI-78D3 reduced the phosphorylation state of c-Jun. Immunohistochemical staining demonstrated the expression of JNK in smooth muscle cells of human prostate tissue. Fluorescence staining showed that alpha(1A)-adrenoceptors and JNK are expressed in the same cells. CONCLUSIONS AND IMPLICATIONS Activation of JNK is involved in alpha(1)-adrenoceptor-induced prostate smooth muscle contraction. Models of alpha(1)-adrenoceptor-mediated prostate smooth muscle contraction should include this JNK-dependent mechanism.
