Steroidal drugs subvert SARS-CoV-2 interaction with ACE2 receptors

A new study by Italian researchers and published online on the preprint server bioRxiv* in June 2020 reports the ability of several existing steroidal drugs to reduce the binding of the SARS-CoV-2 to the ACE2 receptor. This could help define newer strategies using viral entry blockers to reduce viral load.
