NCIt definition : The phenethyl alcohol ester of caffeic acid and a bioactive component of honeybee
hive propolis, with antineoplastic, cytoprotective and immunomodulating activities.
Upon administration, caffeic acid phenethyl ester (CAPE) inhibits the activation of
nuclear transcription factor NF-kappa B and may suppress p70S6K and Akt-driven signaling
pathways. In addition, CAPE inhibits PDGF-induced proliferation of vascular smooth
muscle cells through the activation of p38 mitogen-activated protein kinase (MAPK)
and hypoxia-inducible factor (HIF)-1alpha and subsequent induction of heme oxygenase-1
(HO-1).;
