A Lipopeptide Nasal Spray inhibits SARS-CO-V2 infection in Ferrets

Nasal spray contains a cholesterol linked lipopeptide which binds to the S2 region of SARS-CO-V2 spike in proximity to the HR2 domain. This prevents it from contracting towards the HR1 domain and therby inhibits cell fusion and infection.
