Chemical Name: (1R)-2-[12-[(2R)-2-(Benzoyloxy)propyl]-3,10-dihydro-4,9-dihydroxy-2,6,7,11-tetramethoxy-3,10-dioxo-1-perylenyl]-1-methylethylcarbonic acid 4-hydroxyphenyl ester

Biological Activity

Potent, selective and photo-dependent inhibitor of protein kinase C that targets the regulatory domain (IC50 = 50 nM). Displays > 1000-fold selectivity over other protein kinases such as cAMP-dependent protein kinase and tyrosine-specific protein kinase. Inhibits cell proliferation of malignant glioma cells in light-treated conditions in vitro (IC50 ~ 40 - 60 nM). Also an antagonist of the Tcf/β-catenin complex.
