Are SARS-CoV-2 protease inhibitors effective antivirals in treating COVID-19?

Many antiviral development studies have focused on the possibility of inhibiting the main viral protease (Mpro), and papain-like protease (PLpro), given their central role in viral replication. A new study draws attention to the high odds that these may not have anti-infective activity because of the redundant pathways present in human host cells.
