| General Comments |
| Coronavirus RdRp is a highly investigated molecular target for antiviral drug development [4,8,12], and is the target of the much publicised drug remdesivir. Although RdRp (nsp12) is strictly a component of the SARS-CoV-2 replicase polyprotein we have included it as a separate entity to allow us to more sensibly curate pharmacological information (particularly regarding inhibitor development) that is specific for this enzyme. RdRp functions as a component of a genome replication protein complex that also contains nsp7 and nsp8 [5-6]. RdRp-mediated replication can be primer-dependent, but RdRp is also capable of de novo (primer-independent) RNA synthesis [5]. Because of the conserved structure of the key drug-binding pockets between SARS-CoV-2, SARS-CoV, and MERS-CoV RdRps, redeploying known SARS-CoV and MERS-CoV inhibitors for SARS-CoV-2 is an obvious strategy to combat SARS-CoV-2. To enhance therapeutic efficacy a sensible strategy would be to develop a multi-targeted combination of RdRp inhibitors with approved or clinical-stage drug candidates against other viral and/or host proteins. |
