生物活性

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

体外研究
(In Vitro)

Isoquercetin (Quercetin 3-glucoside; 5-20 μM; 24 hours) substantially reduces ethanol-induced cytotoxicity , protects hepatic cells against ethanol-stimulated liver injury[1]. Isoquercetin (10 μM; pre-treat 1 hour) dramatically downregulates the levels of ethanol-induced iNOS protein expression in HepG2 cells[1].

上海金畔生物科技有限公司 has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Viability Assay[1]

Cell Line: HepG2 cells
Concentration: 5 μM, 10 μM, 20 μM
Incubation Time: 24 hours
