In short, ABET distrupt viral replication...
But more importantly, it also inhibits expression of Angiotensing Convetting Enzyme 2 (AcE2), the receptor used by the virus to get entry into the cells.
In order for the virus to be effective, it 1st has to get entery into cells, & then use to cell DNA macinaty to replicate & reproduce!
it seems that ABET inhibit both of these princesses!
