ABSTRACT
Coronavirus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has rapidly become a global pandemic. Although great efforts have been made to develop effective therapeutic interventions, only the nucleotide analog remdesivir was approved for emergency use against COVID-19. Remdesivir targets the RNA-dependent RNA polymerase (RdRp), an essential enzyme for viral RNA replication and a promising drug target for COVID-19. Recently, several structures of RdRp in complex with substrate RNA and remdesivir were reported, providing insights into the mechanisms of RNA recognition by RdRp. These structures also reveal the mechanism of RdRp inhibition by nucleotide inhibitors and offer a molecular template for the development of RdRp-targeting drugs. This review discusses the recognition mechanism of RNA and nucleotide inhibitor by RdRp, and its implication in drug discovery.
