From nature to medicine: bioactive compounds in the battle against SARS-CoV-2

Abstract

The COVID-19 pandemic has driven the search for new therapeutic agents against SARS-CoV-2. Natural products have shown promise as sources of bioactive compounds with antiviral properties. This letter highlights the potential of these compounds in developing effective COVID-19 therapies. Quercetin, found in fruits and vegetables, has demonstrated antiviral activity by inhibiting viral replication. Glycyrrhizin, from licorice root, can modulate host cell signaling to inhibit SARS-CoV-2 replication. Curcumin, from turmeric, disrupts the interaction between the virus’s spike protein and the ACE2 receptor, preventing viral entry. Additionally, compounds like resveratrol possess immunomodulatory properties that can reduce the hyperinflammatory response in severe COVID-19. Despite these promising findings, the variability of natural extracts and potential side effects necessitate rigorous clinical trials. Natural product-derived bioactive compounds represent a promising avenue for novel COVID-19 therapies, warranting further investigation and clinical validation to uncover effective treatments and enhance preparedness for future outbreaks.
