An all-out assault on SARS-CoV-2 replication

Abstract

The coronavirus pandemic has had a huge impact on public health with over 165 million people infected, 3.4 million deaths and a hugely deleterious effect on most economies. While vaccination effectively protects against the disease it is likely that viruses will evolve that can replicate in hosts immunised with the present vaccines. Thus, there is a great unmet need for effective antivirals that can block the development of serious disease in infected patients. The seven papers published in this issue of the Biochemical Journal address this need by expressing and purifying components required for viral replication, developing biochemical assays for these components and using the assays to screen a library of pre-existing pharmaceuticals for drugs that inhibited the target in vitro and inhibited viral replication in cell culture. The candidate drugs obtained are potential antivirals that may protect against SARS-CoV-2 infection. While not all the antiviral candidates will make it through to the clinic, they will be useful tool compounds and can act as the starting point for further drug discovery programmes.
