A drug screening toolkit based on the -1 ribosomal frameshifting of SARS-CoV-2.

The -1 ribosomal frameshifting is vital for the translation of the open reading frame (ORF)1b in SARS-CoV-2. The products of ORF1b participate in viral replication. Therefore, changing the frameshift frequency reduces the survival of the virus. This study aimed to successfully develop a toolkit for screening antiviral drugs. Finally, the FDA-approved drug library was screened, revealing that ivacaftor and (-)-Huperzine A worked well in changing the -1 ribosomal frameshifting of SARS-CoV-2 in vitro.
