Caffeic Acid is an endogenous phenolic phytochemical compound that exists in plants and many foods. A major metabolite product upon hydrolization of chlorogenic acid caffeic acid inhibits a number of lipoxygenases such as 5-LO (5-lipoxygenase), in a non-competitive manner, and 12-LO (12-lipoxygenase) inhibiting leukotriene synthesis resulting in further inhibition of immunoregulation. Caffeic Acid has also been shown to inhibit arachidonic acid metabolism in platelets at high doses. It has been observed to stimulate prostaglandin synthesis at high doses. Caffeic Acid is an inhibitor of GST, ODC, Tyk and Xanthine Oxidase.
