Peptide-conjugated morpholino oligomers effectively inhibit SARS-CoV-2 in vero cells

The hunt for antivirals has reached an unprecedented pace in light of the coronavirus 2019 (COVID-19) pandemic. The causal agent for this disease – severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) – has already infected over 52 million people worldwide, and has subsequently claimed over 1.3 million lives. However, among the innumerable promising drug candidates that help battle the virus and mitigate its damage, none have yet made it to the clinic.
