Description
 Caffeic acid phenethyl ester (CAPE) is the active component of propolis,  a honeybee hive product. Caffeic acid phenethyl ester is a specific  inhibitor of the nuclear transcription factor, NF-κB. CAPE has been  shown to significantly suppress the Lipoxygenase pathway of arachidonic  acid metabolism during inflammation. Caffeic acid phenethyl ester  inhibits HIV-1 integrase, and also inhibits proliferation of transformed  cells. It induces apoptosis in transformed fibroblasts, and interferes  with EGF signal transduction affecting both protein kinase C and  Ornithine Decarboxylase activity.
