A novel coronavirus (SARS-CoV-2) has caused a global COVID-19 pandemic of respiratory disease in 2020 (1). RNA-dependent RNA polymerase (RdRp) is an enzyme that is crucial to life cycle of RNA viruses including coronaviruses (2). RdRp catalyzes the synthesis of viral RNA, thereby playing a central role in the replication and transcription cycle of COVID-19 viruses, possibly in complex with nsp7 and nsp8 (3). Therefore, RdRp is a prime target for nucleotide analog antiviral inhibitors, such as remedesivir, for development of new antiviral therapeutics (4).
