Dr. Diwan clearly knows. And he’s going to invent something else too: “The various receptors used by different coronaviruses all appear to fall in the broad family of membrane-associated serine proteases. As a family, they share several structural features. Their substrate specificities are dictated by specific amino acid residues and their positions.”

This is the tip of the iceberg. All virus variants share common traits. Dr. Diwan is not playing games. He is very educated and innovative.

“Here it is: “Favirpravir is a broad-spectrum nucleoside-like analog drug that is in clinical testing against SARS-CoV-2, originally developed by Fujifilm. We tested these drug candidates for anti-viral effectiveness against two distinctly different, unrelated coronaviruses that cause human disease, namely hCoV-NL63, and hCoV-229E. The assays evaluated the reduction caused by the drug candidate in cell death upon viral infection, formally known as cytopathic effects (CPE) assays.

We found that the same two nanoviricides drug candidates were highly effective against hCoV-NL63, the coronavirus that uses the same cellular receptor as SARS-CoV-2, as well as another coronavirus, namely hCoV-229E, that causes seasonal common colds in humans. HCoV-229E uses the APN (Aminopeptidase-N) membrane protein on human cells as its receptor to enter cells, different from the ACE2 receptor used by hCoV-NL63 and SARS-CoV-2. ACE2 and APN may be considered to belong to a common superfamily of enzyme membrane proteins in terms of biophysics.

Their substrate specificities are dictated by specific amino acid residues and their positions.”
