Abstract
Background: As COVID-19 pandemic continues to affect people’s lives, the government
of India gave emergency use approval to the ayurvedic antimalarial drug Ayush-64 in April
2021 to treat asymptomatic COVID-19 positive and mild COVID-19 positive patients.
Objective: This study aims to explore the therapeutic potential of Ayush-64 to treat COVID-19 and
provide a new approach for repurposing Ayurvedic drugs.
Methods: The bioactives present in Ayush-64 were found along with their targets, and a plantbioactive-
target network was created. A protein-protein interaction network of the common targets
of Ayush-64 and COVID-19 was constructed and analyzed to find the key targets of Ayush-64 associated
with the disease. Gene ontology and pathway enrichment analysis were performed to find
COVID-19 related biological processes and pathways involved by the key targets. The key bioactives
were docked with SARS-CoV-2 main protease 3CL, native Human Angiotensin-converting
Enzyme ACE2, Spike protein S1, and RNA-dependent RNA polymerase RdRp.
Results: From the 336 targets for Ayush-64, we found 38 key targets. Functional enrichment analysis
of the key targets resulted in 121 gene ontology terms and 38 pathways. When molecular
docking was performed with four receptors, thirteen bioactives showed good binding affinity comparable
to that of the eight drugs presently used to treat COVID-19.
Conclusion: Network pharmacological analysis and molecular docking study of Ayush-64 revealed
that it can be recommended to treat COVID-19. Further in vitro and in vivo studies are needed
to confirm the results. The study demonstrated a new approach for repurposing Ayurvedic drugs.
