Effects of Functional Groups and Sugar Composition of Quercetin Derivatives on Their Radical Scavenging Properties

Quercetin derivatives are widespread in the plant kingdom and exhibit various biological actions. The aim of this study was to investigate the structure-activity relationships of quercetin derivatives, with a focus on the influence of functional groups and sugar composition on their antioxidant capacity. A series of quercetin derivatives were therefore prepared and assessed for their DPPH radical scavenging properties. Isoquercetin O-gallates were more potent radical scavengers than quercetin. The systematic analysis highlights the importance of the distribution of hydroxy substituents in isoquercetin O-gallates to their potency.

NOVEL FLAVANONE DERIVATIVE

Provided is a novel antimicrobial agent. More specifically, provided is a novel antimicrobial agent capable of effectively acting on various resistant bacteria such as VSSA, MRSA, VISA, VRE, and VRSA. A novel flavanone derivative having a six-membered monosaccharide derivative, specifically, a glucose derivative or a galactose derivative is capable of effectively acting on the bacteria. More specifically, a compound represented by the general formula (I) is capable of effectively acting on the bacteria. (In the formula: X represents a six-membered monosaccharide derivative; and Y is substituted by a hydroxyl group.)

Quercetin diacylglycoside analogues showing dual inhibition of DNA gyrase and topoisomerase IV as novel antibacterial agents

A structure-guided molecular design approach was used to optimize quercetin diacylglycoside analogues that inhibit bacterial DNA gyrase and topoisomerase IV and show potent antibacterial activity against a wide spectrum of relevant pathogens responsible f

Binding interaction of quercetin-3-β-galactoside and its synthetic derivatives with SARS-CoV 3CLpro: Structure-activity relationship studies reveal salient pharmacophore features

The 3C-like protease (3CLpro) of severe acute respiratory syndrome-associated coronavirus (SARS-CoV) is one of the most promising targets for discovery of drugs against SARS, because of its critical role in the viral life cycle. In this study,

Synthesis and biological evaluation of flavonoids as vasorelaxant agents

Several 5,7-dihydroxyflavone and quercetin 3-O-glycosides have been synthesized and evaluated for vasorelaxant activity. A logP-activity relationship amongst flavonoids was suggested.
