Quercetin (Standard)

Quercetin (Standard) is the analytical standard of Quercetin. This product is intended for research and analytical applications. Quercetin, a natural flavonoid, is a stimulator of recombinant SIRT1 and also a PI3K inhibitor with IC50 of 2.4 μM, 3.0 μM and 5.4 μM for PI3K γ, PI3K δ and PI3K β, respectively^[1]. IC50 & Target:IC50: 2.4±0.6 μM (PI3K γ), 3.0±0.0 μM (PI3K δ), 5.4±0.3 μM (PI3K β)^[1] In Vitro: Quercetin is a type of plant-based chemical, or phytochemical, used as an ingredient in supplements, beverages or foods. In several studies, it may have anti-inflammatory and antioxidant properties, and it is being investigated for a wide range of potential health benefits. Quercetin is a PI3K inhibitor with IC₅₀ of 2.4-5.4 μM. Quercetin strongly abrogates PI3K and Src kinases, mildly inhibits Akt1/2, and slightly affected PKC, p38 and ERK1/2^[1]. Quercetin inhibits TNF-induced LDH% release, EC-dependent neutrophils adhesion to bovine pulmonary artery endothelial cells (BPAEC), and BPAEC DNA synthesis and proliferation^[2]. In Vivo: Combination of Quercetin (75 mg/kg) and 2-Methoxyestradiol enhances inhibition of human prostate cancer LNCaP and PC-3 cells xenograft tumor growth^[3].
