Virtual screening of phytochemicals was performed through molecular docking to identify the potential hits that can inhibit the effects of SARS-CoV-2. Considering the published literature on medicinal importance, the phytochemicals from tulsi and wooden apple were selected to search potential inhibitors for RdRp (RNA dependent RNA polymerase) of SARS-CoV-2. The in silico computational results revealed that the phytochemicals such as Limonin, Obacunone, Rutaevin,(-)-(2S)-5,3’-Dihydroxy-4’-methoxy-6’’,6’’-dimethylchromeno-(7,8,2’’,3’’)-flavanone, Lupeol, 5-Hydroxy-2-(-hydroxyphenyl)-7-methoxy-6-(3-methylbut-2-enyl)chroman-4-one, Vitexin, Orientin, and Urosolic acid were found to be effective against the target RdRp(RNA dependent RNA polymerase) of SARS-CoV-2. The protein-ligand interaction study revealed that these phytochemicals bind with the amino acid residues at the active site of the target proteins with a higher binding affinity than remdesivir. Therefore, the core structure of these potential hits can be used for further lead optimization to design drugs for SARS-CoV-2. Also, the medicinal plants containing these phytochemicals like tulsi and wooden apple can be used to formulate suitable therapeutic approaches in traditional medicines.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
