There are various ways Quercetin may be effective in inhibiting the effects of the coronavirus.
There are various ways Quercetin may be effective in inhibiting the effects of the coronavirus.
30. 1) Blocking Entry of Virus. Supercomputer simulations by the University of Tennessee and Oak Ridge National Labs to demonstrate which FDA approved chemical compounds may interfere with the coronavirus binding to cells. Out of 8000,Quercetin came in #5. https://chemrxiv.org/articles/Repurposing_Therapeutics_for_the_Wuhan_Coronavirus_nCov-2019_Supercomputer-Based_Docking_to_the_Viral_S_Protein_and_Human_ACE2_Interface/11871402/3
31. More detail: https://twitter.com/ne02012/status/1249760290113089539
32. Yet more detail on the mechanism of how Quercetin may block virus entry into cells. Here is the table from the Supercomputer simulation mentioned above: https://mobile.twitter.com/taitlog/status/1241859474781917184
33. This seems to be the mechanism proposed by the Montreal researchers mentioned above. Here is a piece of the article mentioned above: https://www.mcgilltribune.com/sci-tech/montreal-researchers-propose-a-treatment-for-covid-19-170320/
34. 2) Quercetin acts as a Zinc Ionophore, allowing Zinc to pass the cell membrane and thereby inhibit the replication of the virus. Here is the study demonstrating this: https://pubs.acs.org/doi/full/10.1021/jf5014633
35. This is essentially the same process behind chloroquine/Hydroxychloroquine as they are both Zinc Ionophores. This is one of the leading theories behind their efficacy as anti-viral drugs. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4182877/
36. Here is a great video demonstrating how chloroquine/Hydroxychloroquine work as zinc ionophores to inhibit virus replication:
37. As an aside I would like to share two recent documents showing the strong efficacy of Hydroxychloroquine and Zinc in fighting Covid-19.
A) https://docs.google.com/document/u/0/d/1ka76CL50hR_a0b5oIhEAVY4gfyqkJcBxXBcP0r2nrz0/mobilebasic
A) https://docs.google.com/document/u/0/d/1ka76CL50hR_a0b5oIhEAVY4gfyqkJcBxXBcP0r2nrz0/mobilebasic
38. B) Here is the second document on Hydroxychloroquine’s efficacy on treating COVID-19: https://docs.google.com/document/d/1O6Cls-Oz2ZAgJuyDbnICEGjMvQPEyM-aaXARUomR9Ww
39. Zinc- The following is a study showing Zn2+ Inhibits Coronavirus and Arterivirus RNA Polymerase Activity In Vitro and Zinc Ionophores Block the Replication of These Viruses in Cell Culture:

42. This is a very detailed explanation on the connection between chloroquine, zinc and Quercetin and illustrates clearly how they share similar mechanisms. https://dadamo.com/dangerous/2020/04/07/covid-19-chloroquine-zinc-and-quercetin/
43. 3) Another reason why Quercetin may be effective at combatting COVID19 is due to the fact that it may inhibit the cytokine storm induced by the coronavirus: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6273652/#sec3-molecules-21-00450title
44. 4) Another potential Quercetin anti-Covid-19 mechanism: https://mobile.twitter.com/taitlog/status/1248776042291933186
