Wine contains various polyphenols such as flavonoids, anthocyanins, and tannins. These molecules are responsible for the quality of wines, influencing their astringency, bitterness, and color and they are considered to have antioxidant activity. Polyphenols, extracted from grapes during the processes of vinification, could protect the body cells against reactive oxygen species level increase and could be useful to rescue several pathologies where oxidative stress represents the main cause. For that, in this study, red and white wine, provided by an Italian vinery (Marche region), have been analyzed...

Tamoxifen is effective in breast cancer therapy in postmenopausal women; however, it causes adverse effects that alter the glycolytic pathway and induce hyperglycemia. Quercetin, a flavonoid with antioxidant potential, inhibits butyrylcholinesterase (BuChE), which is positively associated with hyperglycemia. Therefore, this study investigated the effect of quercetin on tamoxifen-induced hyperglycemia, using BuChE activity as a bioindicator in adult ovariectomized Wistar rats. The ovariectomized rats were treated orally for 14 days with different concentrations of quercetin (2...

Curcumin, a bioactive compound in Curcuma longa, exhibits various pharmacological activities, including antimalarial effects. In silico docking simulation studies suggest that curcumin possesses glycogen synthase kinase-3β (GSK3β)-inhibitory properties. The involvement of GSK3 in the antimalarial effects in vivo is yet to be demonstrated. In this study, we aimed to evaluate whether the antimalarial effects of curcumin involve phosphorylation of host GSK3β. Intraperitoneal administration of curcumin into Plasmodium berghei NK65-infected mice resulted in dose-dependent chemosuppression of parasitemia development...
