Determination of Quercetin by a Siloxane-Polyester/Poly-L-Lysine Nanocomposite Modified Glassy Carbon Electrode
(2016-06-12)
Poly-L-lysine incorporated in the nanocavities of polysiloxane-poly(propylene) oxide is reported as an electrochemical sensor for quercetin. A glassy carbon electrode coated by poly-L-lysine/polysiloxane-poly(propylene) ...
Quercetin and related flavonoids conserve their antioxidant properties despite undergoing chemical or enzymatic oxidation
(Elsevier, 2017)
Oxidation of a phenolic group in quercetin is assumed to compromise its antioxidant properties. To
address this assumption, the ROS-scavenging, Folin-Ciocalteau- and Fe-reducing capacities of quercetin
and thirteen ...
Pharmacological activity of quercetin and 5-caffeoylquinic acid oral intake in male Balb/c mice with lung adenocarcinoma
(Elsevier Science Inc., 2020-01)
Lung adenocarcinoma (LAC) is a major worldwide cause of death by cancer, it shows high aggressiveness, functional decline, systemic compromise and severecachexia, which might be counteracted by dietary redox-active ...
Spectroscopic and Thermodynamic Study of Chrysin and Quercetin Complexes with Cu(II)
(American Chemical Society, 2016-02)
Chrysin and quercetin are natural polyphenolic compounds which present benefits in human health because of their biological properties. These flavonoids also have the capacity to complex a wide variety of metallic ions ...
Quercetin in lyotropic liquid crystalline formulations: Physical, chemical and functional stability
(SPRINGER, 2008)
The purpose of this study was to develop a lyotropic liquid crystalline formulation using the emulsifier vitamin E TPGS and evaluate its behavior after incorporation of a flavonoid, quercetin. The physical (macro and ...
Quercetin inhibits UV irradiation-induced inflammatory cytokine production in primary human keratinocytes by suppressing NF-kappa B pathway
(ELSEVIER IRELAND LTD, 2011)
Background: Topical flavonoids, such as quercetin, have been shown to reduce ultraviolet (UV) irradiation-mediated skin damage. However, the mechanisms and signaling pathways involved in this protective effect are not ...
Chemometrical-electrochemical investigation for comparing inhibitory effects of quercetin and its sulfonamide derivative on human carbonic anhydrase II: Theoretical and experimental evidence
(Elsevier Science, 2019-09-01)
This paper reports results of a valuable study on investigation of inhibitory effects of the sulfonamide derivative of quercetin (QD) on human carbonic anhydrase II (CA-II) by electrochemical and chemometrical approaches. ...
Quercetin ameliorates glucose and lipid metabolism and improves antioxidant status in postnatally monosodium glutamate-induced metabolic alterations
(Pergamon-Elsevier B.V. Ltd, 2012-10-01)
We reported the effects of quercetin on metabolic and hormonal profile as well as serum antioxidant activities in a model of MSG (monosodium glutamate)-induced obesity. Rats were divided into 4 groups: MSG group, submitted ...
