jnk in 7

JNK-IN-7 (JNK inhibitor) is a selective JNK1/2/3 inhibitor (IC50: 1.54/1.99/0.75 nM). It can also inhibit phosphorylation of c-Jun, which is a substrate of JNK kinase.

JNK3 inhibitor-7, a potent and orally active compound that can cross the blood-brain barrier, acts as a JNK3 inhibitor with IC50 values of 53 nM for JNK3, 973 nM for JNK2, and 1039 nM for JNK1. Demonstrating significant neuroprotective effects, JNK3 inhibitor-7 holds potential for Alzheimer’s disease (AD) research [1].

Stephacidin B is a fungal metabolite that has been found inA. ochraceus.1Dimeric stephacidin B is rapidly converted to a monomer, avrainvillamide ,in vitro.2Stephacidin B is cytotoxic to a variety of cancer cells, including testosterone-independent PC3 and -sensitive LNCaP prostate cancer cells (IC50s = 0.37 and 0.06 μM, respectively) and estradiol-independent SK-BR-3 and -sensitive MCF-7 breast cancer cells (IC50s = 0.32 and 0.27 μM, respectively).1It induces apoptosis in HepG2 and Huh7 hepatocellular carcinoma cells when used at a concentration of 4 μM.3 1.Qian-Cutrone, J., Huang, S., Shu, Y.-Z., et al.Stephacidin A and B: Two structurally novel, selective inhibitors of the testosterone-dependent prostate LNCaP cellsJ.
