Phenylethyl 3,4-dihydroxycinnamate is a potent and specific inhibitor of nuclear transcription factor, NF-κB, activation. It has been shown to significantly suppress the lipoxygenase pathway of arachidonic acid metabolism during inflammation. It 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.


Light sensitive. Incompatible with oxidizing agents and heat.
