Resum
Although the COVID-19 pandemic was declared no longer a global emergency by the World Health Organization in May 2023, SARS-CoV-2 is still infecting people across the world. Many therapeutic oligonucleotides such as ASOs, siRNAs, or CRISPR-based systems emerged as promising antiviral strategies for the treatment of SARS-CoV-2. In this work, we explored the inhibitory potential on SARS-CoV-2 replication of Polypurine Reverse Hoogsteen Hairpins (PPRHs), CC1-PPRH, and CC3-PPRH, targeting specific polypyrimidine sequences within the replicase and Spike regions, respectively, and previously validated for COVID-19 diagnosis. Both PPRHs are bound to their target sequences in the viral genome with high affinity in the order of nM. In vitro, both PPRHs reduced viral replication by more than 92% when transfected into VERO-E6 cells 24 h prior to infection with SARS-CoV-2. In vivo intranasal administration of CC1-PPRH in K18-hACE2 mice expressing the human ACE receptor protected all the animals from SARS-CoV-2 infection. The properties of PPRHs position them as promising candidates for the development of novel therapeutics against SARS-CoV-2 and other viral infections.
