主 题:acute threat conclusion
摘 要:Emerging and recurrent infectious diseases caused by human coronaviruses(HCoVs)continue to pose a significant threat to global public health *** light of this ongoing threat,the development of a broad-spectrum drug to combat HCoVs is an urgently ***,we report a series of anti-pan-coronavirus ssDNA aptamers screened using Systematic Evolution of Ligands by Exponential Enrichment(SELEX).These aptamers have nanomolar affinity with the nucleocapsid protein(NP)of Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2)and also show excellent binding efficiency to the N proteins of both SARS,MERS,HCoV-OC43 and-NL63 with affinity KD values of 1.31 to 135.36 *** aptamer-based therapeutics exhibited potent antiviral activity against both the authentic SARS-CoV-2 prototype strain and the Omicron variant(BA.5)with EC50 values at 2.00 nM and 41.08 nM,*** protein docking analysis also evidenced that these aptamers exhibit strong affinities for N proteins of pan-coronavirus and other HCoVs(−229E and-HKU1).In conclusion,we have identified six aptamers with a high pan-coronavirus antiviral activity,which could potentially serve as an effective strategy for preventing infections by unknown coronaviruses and addressing the ongoing global health threat.
