General description

Quercetin 3-β-D-glucoside (Q3G), also known as isoquercitrin, is one of the major glycosidic forms of quercetin. It is a mono-glucoside, first isolated from the seed pods of Cercis canadensis L., it is also found in various plants, vegetables, and fruits. Q3G has the basic chemical structure of a flavonoid, with a glucose molecule attached to the C-3 of quercetin.

Application

Quercetin 3-β-D-glucoside has been used:
  • as a dietary flavonoid supplement to check its binding capacity with human small ubiquitin-related modifier 1 (SUMO1) protein using surface plasmon resonance (SPR)
  • as an inhibitor for Escherichia coli adenosine triphosphate (ATP) synthase
  • as an anti-aggregation agent to test its activity against β-amyloid, green fluorescent protein (GFP), and chymotrypsinogen proteins

Biochem/physiol Actions

Quercetin 3-β-D-glucoside possesses strong antioxidant and anti-inflammatory activities. Being a potent oxygen-radical scavenger, it is a neuroprotective agent that improves Alzheimer′s disease (AD) condition in mice models. It has shown antiproliferative activity against colon, lung, and hepatocellular cell lines and MCF-7 human breast cancer cells in combination with apple extracts.

We have studied the inhibitory effect of five polyphenols namely, resveratrol, piceatannol, quercetin, quercetrin, and quercetin-3-beta-D glucoside on Escherichia coli ATP synthase. Recently published X-ray crystal structures of bovine mitochondrial ATP synthase inhibited by resveratrol, piceatannol, and quercetin, suggest that

The flavonol quercetin in plants and foods occurs predominantly in the form of glycoside whose sugar moiety affects the bioavailability and the mechanism of its biological activities. The antiproliferative activities of quercetin derivatives such as quercetin aglycone, quercetin-3-β-D-glucoside (Q3G), and

Protein aggregation is a common problem during the purification and formulation of therapeutic proteins. Here we report that polyphenolic disaccharides are unusually effective at preventing protein aggregation. We find that two polyphenolic glycosides-naringin and rutin-endow diverse proteins with the ability
