Brazilin exhibits cancer preventive, anti-hepatotoxicity, antiplatelet activity, and anti-inflammatory activities, it also inhibits UVB-induced MMP-1/3 expressions and secretions by suppressing of NF-κB activation in human dermal fibroblasts, thus, it might be used as a potential agent for treatment of UV-induced skin photoaging. Brazilin has anti-IKK activity, can selectively disrupt proximal IL-1 receptor signaling complex formation by targeting an IKK-upstream signaling components. Brazilin induces vasorelaxation by the increasing intracellular Ca(2+) concentration in endothelial cells of blood vessels and hence activating Ca(2+)/calmodulin-dependent NO synthesis. Brazilin is a tertiary alcohol, a member of catechols and an organic heterotetracyclic compound. It has a role as an antioxidant, a biological pigment, an antibacterial agent, an antineoplastic agent, a hepatoprotective agent, an anti-inflammatory agent, an apoptosis inducer, a NF-kappaB inhibitor, a plant metabolite and a histological dye.

Caftaric acid is an inhibitor of the protein-protein interactions mediated by the Src-family kinases, which has anti-mutagenicity. Caftaric acid is the major dietary polyphenol present in various foods, it before methamphetamine injections can prevent liver toxicity and oxidative stress.
