Biological Activity:
Quercetin (Sophoretin) is a PI3K and PKC inhibitor with IC50 of 3.8 μM and 15µg/ml. It strongly abrogated PI3K and Src kinases, mildly inhibited Akt1/2, and slightly affected PKC, p38 and ERK1/2. [1][2] Quercetin is a naturally-occurring polar auxin transport inhibitor with IC50 of 0.8, 16.7, 6.1, 11.36 µM for the inhibition of LDH% release, the inhibition of TNF-induced PMN-EC adhesion, TNF-induced inhibition of DNA synthesis and proliferation. It is a type of plant-based chemical, or phytochemical, known as a flavonol and a plant-derived flavonoid found in fruits, vegetables, leaves and grains. It also may be 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.
