PKC Activator VII, CGK062

A cell permeable coumarin-containing compound that is shown to activate PKCα activity toward GST-β-catenin or PKC substrate peptide in cell-free kinase assays (12.5 & 25 µM) and induce cellular PKCα membrane translocation (Effective conc. 12.5 to 50 µM in HEK293, PC3, SNU475, and SW480 cultures) as well as PKCα-mediated β-catenin phosphorylation (Ser33/37/45) and subsequent β-catenin degradation in a F-box Ub ligase complex component β-TrCP- (β-transducin repeat-containing protein) dependent, but GSK-3β-independent, manner. Effectively affects the viability of CRT- (β-catenin response transcription) dependent cancer cells (IC₅₀ = 1.62, 5.71, 9.40, 11.41, and 18.60 µM, respectively, in SW480, HCT15, PC3, SNU475, and DLD-1 cultures; 48 h) in vitro and suppresses PC3-derived tumor expansion in mice (23% and 11% of control size, respectively, with 50 or 100 mg/kg daily i.p. dose for 4 wks) in vivo, while exhibiting little cytotoxicity toward WI38 normal fibroblasts (IC₅₀ = 74.83 µM; 48 h).
