Quercetin and Thyroid

Antioxidants
Quercetin is the most abundant flavonoid present in fruits and vegetables. For its antiproliferative, antiviral, anti-inflammatory and antioxidants activities, it is an active ingredient of several herbal remedies and is available as a nutraceutical. Experimental studies performed in vitro have demonstrated that quercetin inhibits growth and function ...

Quercetin attenuates renal ischemia/reperfusion injury via an activation of AMP-activated protein kinase-regulated autophagy pathway

, 2017
Renal ischemia/reperfusion (I/R) is a major cause of acute renal failure. Quercetin, a flavonoid antioxidant, presents in many kinds of food. The molecular mechanism of quercetin on renal protection during I/R is still unclear.

Quercetin Induces Lipid Domain-Dependent Permeability

, 2021
In this work, we present our results on quercetin interaction with distinct model membranes exploring the importance of lipid phases, ld, ld/lo and ld+lo+so, to the action of this flavonoid in bilayers and possibly contributing to clarifying some ...

Effect of matter other than grapes on quercetin evolution and key wine parameters

IVES Technical Reviews
Quercetin instability is a practical concern in red wines because low-solubility quercetin aglycone can form haze or crystals during storage. This study evaluated whether sub-threshold levels of matter other than grapes (MOG; < 3 % w/v), as encountered ...

Evaluation of the Mrp2-mediated flavonoid-drug interaction potential of quercetin in rats and in vitro models

Asian Journal of Pharmaceutical Sciences, 2019
Quercetin is a biologically active flavonoid that has been used as a popular health supplement. It is reported that quercetin may cause flavonoid-drug interaction mediated by P-glycoprotein, the most predominant efflux transporter.
