Conclusion

COVID-19 virus is a severe health fear with high mortality and fatal effect. Although there is no licensed drug till now, efforts directed to investigate a potential therapeutics or drug versus SARS-CoV-2. Computational modeling and virtual screening through molecular docking employed to screen the potent inhibitors against the virus. In this study, the antiviral effects of some potent drugs extracted from the Portulaca oleracea plant were screened for their ability to inhibit SARS-CoV-2 main proteas. The obtained results are based on theoretical docking simulation, without in vivo or in vitro antiviral assessment. The docking outputs confirmed that the screened polysaccharides bind tightly to 6y84 protease, so can inhibit the infection. Where the 2nd ligand exhibits a binding score of -6.58175, owing to the formation of H-bonding with Asn221 & Arg217, so it is anticipated that it is a potential inhibitor for coronavirus pneumonia.

Israel -all the big “scientists” here-does not deal with plants..As you already know….China, Iran, Egypt, Haiti etc DO!
