Immensely aggravated situation of COVID-19 has pushed the scientific community towards developing novel therapeutics to fight the pandemic Small molecules can possibly prevent the spreading infection by targeting specific vital components of the viral genome Non-structural protein 15 (Nsp15) has emerged as a promising target for such inhibitor molecules In this investigation, we docked bioactive molecules of tea onto the active site of Nsp15 Based on their docking scores, top three molecules (Barrigenol, Kaempferol, and Myricetin) were selected and their conformational behavior was analyzed via molecular dynamics simulations and MMPBSA calculations The results indicated that the protein had well adapted the ligands in the binding pocket thereby forming stable complexes These molecules displayed low binding energy during MMPBSA calculations, substantiating their strong association with Nsp15 The inhibitory potential of these molecules could further be examined by in-vivo and in-vitro investigations to validate their use as inhibitors against Nsp15 of SARS-CoV2
An in-silico evaluation of different bioactive molecules of tea for their inhibition potency against non structural protein-15 of SARS-CoV-2. (Special Issue: Extraction, processing, and encapsulation of food bioactive compounds.)
