Fascinating antiviral application of cyclodextrins against SARS-COV2. You can find specific nanobodies against different target antigens such as the spike protein of the SARS-CoV-2 virus and or to the ACE2 receptor at the host cell surface, binds to the virus or the ACE2 receptor at the host cell plasma membrane, preventing entry of the SARS-CoV-2 virus. The nanobodies comprise a cyclodextrin; a zinc ionophore; a zinc-containing compound; and, benzalkonium.
