Screening of Kabasura Kudineer Chooranam against COVID-19 through Targeting of Main Protease and RNA-Dependent RNA Polymerase of SARS-CoV-2 by Molecular Docking Studies

Abstract

COVID-19 is the infectious pandemic disease caused by the novel coronavirus. The COVID-19 is spread globally in a short span of time. The Ministry of AYUSH, India which promotes Siddha and other Indian system of medicine recommends the use of formulation like Nilavembu Kudineer and Kaba Sura Kudineer Chooranam (KSKC). The present work seeks to provide the evidence for the action of 74 different constituents of the KSKC formulation acting on two critical targets. That is main protease and SARS-CoV-2 RNA-dependent RNA polymerase target through molecular docking studies. The molecular docking was done by using AutoDock Tools 1.5.6 of the 74 compounds, about 50 compounds yielded docking results against COVID-19 main protease while 42 compounds yielded against SARS-CoV-2 RNA-dependent RNA polymerase. This research has concluded that the KSKC has the lead molecules that inhibits COVID-19’s target of main protease of COVID-19 and SARS-CoV-2 RNA-dependent RNA polymerase.
