Screening for SARS-CoV-2 non-structural protein 14 inhibitors
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) genome generates 16 distinct non-structural proteins (nsp) that constitute the enzymes and accessory proteins responsible for virus replication once inside a host cell. These protein complexes produce and cap RNA strands that will go on to be translated by the host machinery. Capping the RNA in a manner that is recognized as similar to endogenous mRNA ensures compatibility, lessens RNA degradation rates and lowers the probability of triggering an immune response in the host cell.
In a paper recently uploaded to the preprint server
et al. (April 8
th, 2021), inhibitors of one essential SARS-CoV-2 non-structural protein are explored, with four compounds, in particular, identified as potential antiviral leads that exhibit synergistic effects with antiviral drug remdesivir.
