Isoquercitrin (Standard)

Isoquercetin (Standard) is the analytical standard of Isoquercetin. This product is intended for research and analytical applications. 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].
