Identification of potential antiviral compounds from Egyptian sea stars against MERS-CoV with the in vitro and in silico experiments.

Publication date: Apr 02, 2024

Recently, the world faced many epidemics which were caused by viral respiratory pathogens. Marine creatures including Asteroidea class have been one of the recent research topics due to their diverse and complex secondary metabolites. Some of these constituents exhibit antiviral activities. The present study aimed to extract and identify the potential antiviral compounds from Pentaceraster cumingi, Astropecten polyacanthus and Pentaceraster mammillatus. The results showed that promising activity of the methanolic extract of P. cumingi with 50% inhibitory concentration (IC) of 3. 21 mg/ml against MERS-CoV with a selective index (SI) of 13. 975. The biochemical components of the extracts were identified by GC/MS analysis. The Molecular docking study highlighted the virtual mechanism of binding the identified compounds towards three PDB codes of MERS-CoV non-structural protein 10/16. Interestingly, 2-mono Linolein showed promising binding energy of -14. 75 Kcal/mol with the second PDB code (5YNI) and -15. 22 Kcal/mol with the third PDB code (5YNQ).
