The Revelation of Various Compounds Found in Nigella sativa L. (Black Cumin) and Their Possibility to Inhibit COVID-19 Infection Based on the Molecular Docking and Physical Properties

As there is no specified drug available to fight COVID-19, it is essential to have a different strategy to fight this virus. In the present study, using molecular docking, we have identified possible protease inhibitors of COVID-19 by the molecules present in  Nigella  sativa  L.  (black  cumin),  which  is  a  reputed  healing  herb  extensively  used  for  processing  Ayurvedic  and  Unani remedies. Herein, we perform molecular docking and study of various physical properties/descriptors of four derivatives of thymoquinone found in the essential oil of the said seeds and they are compared with the docking results of chloroquine to determine its potential against COVID-19 infection.
