Background:

Quercetin (dihydrate), a natural flavonoid, is a stimulator of recombinant SIRT1 and a PI3K inhibitor with IC50s of 2.4 μM, 3.0 μM and 5.4 μM for PI3K γ, PI3K δ and PI3K β, respectively[1].

Quercetin (dihydrate) 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[1].Quercetin (dihydrate) is a PI3K inhibitor with IC50s of 2.4-5.4 μM. Quercetin dihydrate (Sophoretin dihydrate) strongly abrogates PI3K and Src kinases, mildly inhibits Akt1/2, and slightly affected PKC, p38 and ERK1/2[1].Quercetin (dihydrate) inhibits TNF-induced LDH% release, EC-dependent neutrophils adhesion to bovine pulmonary artery endothelial cells (BPAEC), and BPAEC DNA synthesis and proliferation[2].
