Biological Activity for Quercetin

Quercetin is an antitumor agent; induces apoptosis and inhibits synthesis of heat shock proteins. Inhibits many enzyme systems including tyrosine protein kinase, phospholipase A2, phosphodiesterases, mitochondrial ATPase, PI 3-kinase and protein kinase C. Can also activate Ca2+ and K+ channels and behaves as an agonist at estrogen (GPER) receptors. Blocks cellular entry by influenza A virus via an interaction with hemaglutinin. Inhibits SARS-CoV 3CLpro (IC50 = 73 μM). Targets and eliminates senescent cells. Orally bioavailable.
