Chemical Information
FooDB NameTheaflavin 3,3'-digallate
DescriptionTheaflavin 3,3'-digallate belongs to the class of organic compounds known as catechin gallates. These are organic compounds containing a gallate moiety glycosidically linked to a catechin. Theaflavin 3,3'-digallate is an extremely weak basic (essentially neutral) compound (based on its pKa). Theaflavin 3,3'-digallate is found, on average, in the highest concentration within tea. Theaflavin 3,3'-digallate has also been detected, but not quantified in, german camomiles and peppermints. This could make theaflavin 3,3'-digallate a potential biomarker for the consumption of these foods.

Biological Effects and Interactions
Health Effects / Bioactivities
anti methicillin-resistant Staphylococcus aureus33282 A substance that kills or slows the growth of bacteria.DUKE
immunostimulant50847 A substance that augments, stimulates, activates, potentiates, or modulates the immune response at either the cellular or humoral level. A classical agent (Freund's adjuvant, BCG, Corynebacterium parvum, et al.) contains bacterial antigens. It could also be endogenous (e.g., histamine, interferon, transfer factor, tuftsin, interleukin-1). Its mode of action is either non-specific, resulting in increased immune responsiveness to a wide variety of antigens, or antigen-specific, i.e., affecting a restricted type of immune response to a narrow group of antigens. The therapeutic efficacy is related to its antigen-specific immunoadjuvanticity.DUKE
lipoxygenase inhibitor35856 A compound or agent that combines with lipoxygenase and thereby prevents its substrate-enzyme combination with arachidonic acid and the formation of the icosanoid products hydroxyicosatetraenoic acid and various leukotrienes.DUKE
