Antiviral,immunomodulatory,and anticoagulant effects of quercetin and its derivatives:Potential role in prevention and management of COVID-19
The coronavirus disease 2019(COVID-19)pandemic caused by severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)infection has caused a devastating health crisis worldwide.In this review,we have discussed that prophylactic phytochemical quercetin supplementation in the form of foods or nutraceuticals may help manage the COVID-19 pandemic.The following evidence supports our argument.First,nuclear factor erythroid-derived 2-like 2(NRF2)agonists abrogate replication of SARS-CoV-2 in lung cells,and quercetin is a potent NRF2 agonist.Second,quercetin exerts antiviral activity against several zoonotic coronaviruses,including SARS-CoV-2,mainly by inhibiting the entry of virions into host cells.Third,inflammatory pathways activated by nuclear factor kappa B,inflammasome,and interleukin-6 signals elicit cytokine release syndrome that promotes acute respiratory distress syndrome in patients with COVID-19,and quercetin inhibits these pro-inflammatory signals.Fourth,patients with COVID-19 develop thrombosis,and quercetin mitigates coagulation abnormalities by inhibiting plasma protein disulfide isomerase.This review provides a strong rationale for testing quercetin for the management of COVID-19.
