Results: PPMO designed to base-pair with sequence in the 5'-terminal region or the leader 36 transcription regulatory sequence-region of SARS-CoV-2 genomic RNA were highly 37 efficacious, reducing viral titers by up to 4-6 log10 in cell cultures at 48-72 hours post-infection, 38 in a non-toxic and dose-responsive manner.

In this study, five PPMO were designed to target the 5' UTR 107 and first translation start site-region of SARS-CoV-2 positive sense genomic RNA ( Table 1) . ./cache/cord-336522-y9nzsv95.txt ./txt/cord-336522-y9nzsv95.txt
