Description: Inhibitor of JNK signaling
Chemical Name: (9S,10R,12R)-5-16-Bis[(ethylthio)methyl]-2,3,9,10,11,12-hexahydro-10-hydroxy-9-methyl-1-oxo-9,12-epoxy-1H-diindolo[1,2,3-fg:3',2',1'-kl]pyrrolo[3,4-i][1,6]benzodiazocine-10-carboxylic acid methyl ester
Purity: ≥97% (HPLC)
Biological Activity for CEP 1347
CEP 1347 is a potent inhibitor of mixed lineage kinases MLK3, MLK1 and MLK2 (IC50 values in vitro are 23-39 nM, 38-61 nM and 51-82 nM, respectively), and blocks downstream c-jun N-terminal kinase (JNK) activation (IC50 = 20 nM). CEP 1347 rescues motor neurons undergoing apoptosis (EC50 = 20 nM), blocks Aβ-induced cortical neuron apoptosis (EC50 ~51 nM) and, in an animal model of Huntington's disease, restores BDNF mRNA to wild type levels. CEP 1347 is also a MDM4 inhibitor. It displays inhibition of malignant meningioma cells growth in vitro, and shows anti-tumor activity in a mouse xenograft model of meningioma in vivo. CEP 1347 is orally bioavailable and brain penetrant.
