WHO has declared the outbreak of COVID-19 as a public health emergency of
international concern. The ever-growing new cases have called for an urgent
emergency for specific anti-COVID-19 drugs. Three structural proteins (Membrane,
Envelope and Nucleocapsid protein) play an essential role in the assembly and
formation of the infectious virion particles. Thus, the present study was
designed to identify potential drug candidates from the unique collection of 548
anti-viral compounds (natural and synthetic anti-viral), which target SARS-CoV-2
structural proteins. High-end molecular docking analysis was performed to
characterize the binding affinity of the selected drugs-the ligand, with the
SARS-CoV-2 structural proteins, while high-level Simulation studies analyzed the
stability of drug-protein interactions. The present study identified rutin, a
bioflavonoid and the antibiotic, doxycycline, as the most potent inhibitor of
SARS-CoV-2 envelope protein. Caffeic acid and ferulic acid were found to inhibit
SARS-CoV-2 membrane protein while the anti-viral agent's simeprevir and
grazoprevir showed a high binding affinity for nucleocapsid protein. All these
compounds not only showed excellent pharmacokinetic properties, absorption,
metabolism, minimal toxicity and bioavailability but were also remain stabilized
at the active site of proteins during the MD simulation. Thus, the identified
lead compounds may act as potential molecules for the development of effective
drugs against SARS-CoV-2 by inhibiting the envelope formation, virion assembly
and viral pathogenesis.
