CATECHIN-(4ALPHA->8)-EPICATECHIN Chemical Properties, Uses, Production
Uses
Procyanidin B4 is a bioactive flavonoid and a proanthocyanidin grape seed extract that reduces inflammation and oxidative stress and restores tight junction barrier function in caco-2 colon cells.
Definition
ChEBI: Procyanidin B4 is a proanthocyanidin obtained by the condensation of (-)-epicatechin and (+)-catechin units. It has a role as an antioxidant, an EC 5.99.1.3 [DNA topoisomerase (ATP-hydrolysing)] inhibitor and an antineoplastic agent. It is a proanthocyanidin and a hydroxyflavan. It is functionally related to a (-)-epicatechin and a (+)-catechin.
