In Silico Target Tracking: Molecular Docking and Pharmacokinetic Studies of Naturally Occurring Flavonoid Glycosides and their Activity Against COVID-19 Viral Proteins

The study investigated the potential of ten flavonoid glycosides (Rutin, Nicotiflorin, Naringin, Diosmin, Apigetrin, Spiraeoside, Kaempferol, Quercetin, Isoquercetin, and Astragalin) as SARS-CoV-2 protein (Spike, RdRp, Mpro, and PLpro) inhibitors using molecular docking and pharmacokinetic analysis. Despite extensive research on general antioxidants against SARS-CoV -2, flavonoid glycosides remain understudied. This research aims to bridge this gap by investigating the docking results, which indicate potential inhibitory activity of all tested compounds, with Naringin and Diosmin showing optimal binding to RdRp, Apigetrin to Mpro, Diosmin to Spike protein, and Naringin to PLpro. These findings warrant more in vivo and in vitro research to assess flavonoid glycosides' potential as a treatment for COVID-19.
