<p>The spread of the global COVID-19 pandemic,
the lack of specific treatment and the urgent situation requires use of all
resources to remedy this scourge. In the present study, using molecular
docking, we identify new probable inhibitors of COVID-19 by molecules from <i>Nigella
sativa L</i>, which is highly reputed healing herb in North African societies
and both Islamic and Christian traditions.
The discovery
of the M<sup>pro</sup>
protease
structure in COVID-19 provides a great opportunity to identify potential drug
candidates for treatment. Focusing on the main proteases in CoVs (3CL<sup>pro</sup>/M<sup>pro</sup>) (PDB ID 6LU7 and 2GTB); docking of compounds from <i>Nigella Sativa</i> and drugs under
clinical test was performed using Molecular Operating Environment software
(MOE). Nigelledine docked into 6LU7 active site gives energy complex about -6.29734373
Kcal/mol which is close to the energy score
given by chloroquine (-6.2930522 Kcal/mol) and better than energy score given by
hydroxychloroquine (-5.57386112 Kcal/mol)
and favipiravir (-4.23310471 kcal/mol). Docking into 2GTB active site
showed that α- Hederin gives energy score about-6.50204802 kcal/mol whcih is better energy score given by chloroquine (-6.20844936 kcal/mol), hydroxychloroquine (-5.51465893 kcal/mol)) and
favipiravir (-4.12183571kcal/mol). Nigellidine and α- Hederin appeared to have the best potential to act as COVID-19
treatment. Further, researches are necessary to testify medicinal use of
identified and to encourage preventive use of <i>Nigella Sativa </i>against
coronavirus infection.</p>
