 Use of Isoquercitrin


Quercetin-3-glucoside is a naturally occurring polyphenol that has antioxidant, anti-proliferative, and anti-inflammatory properties.Quercetin-3-glucoside alleviates ethanol-induced hepatotoxicity, oxidative stress, and inflammatory responses via the Nrf2/ARE antioxidant signaling pathway[1].Quercetin-3-glucoside regulates the expression of nitric oxide synthase 2 (NO2) via modulating the nuclear factor-κB (NF-κB) transcription regulation system. Quercetin-3-glucoside has high bioavailability and low toxicity, is a promising candidate agent to prevent birth defects in diabetic pregnancies[2].

In Vitro Quercetin-3-glucoside (5-20 μM; 24 hours) substantially reduces ethanol-induced cytotoxicity , protects hepatic cells against ethanol‐stimulated liver injury[1].Quercetin-3-glucoside (10 μM; pre-treat 1 hour) dramatically downregulates the levels of ethanol-induced iNOS protein expression in HepG2 cells[1]. Cell Viability Assay[1] Cell Line: HepG2 cells Concentration: 5 μM, 10 μM, 20 μM Incubation Time: 24 hours Result: Caused significantly enhanced cell viability as positive controls. Western Blot Analysis[1] Cell Line: HepG2 cells Concentration: 10 μM Incubation Time: 1 hour Result: Decreased ethanol‐ induced iNOS protein expression.
