DIGALLIC ACID Usage And Synthesis

Description

Digallic acid is a natural polyphenolic that can be produced by hydrolysis of gallotannins. Like other polyphenolic compounds, digallic acid has antioxidant activity that can be cytoprotective. Digallic acid inhibits reverse transcriptases from human immunodeficiency virus (Ki = 0.58 μM) and murine leukemia virus. It also inhibits calcium-activated chloride channels, blocking the initial agonist-stimulated chloride current.

Chemical Properties

Off-White Solid

Uses

Digallic Acid is an intermolecular ester of Gallic acid (G188900), a phenolic acid with antioxidant activity. Gallic acid was found to protect human cells against oxidative damage and showed cytotoxicity against cancer cells. Gallic Acid and its esters also show antiviral and antifungal activities.

Definition

ChEBI: Digallic acid is a benzoate ester and a gallate ester. It is functionally related to a gallic acid. It is a conjugate acid of a digallate.
