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 3CL^pro (IC₅₀ = 73 μM). Targets and eliminates senescent cells. Orally bioavailable.
