Coronaviruses (CoVs) are enveloped positive-stranded RNA viruses with spike (S) protein
projections that allow the virus to enter and infect host cells. The S protein is a key virulence
factor determining viral pathogenesis, host tropism, and disease pathogenesis. There are currently
diverse corona viruses that are known to cause disease in humans.
The occurrence of Middle East respiratory syndrome coronavirus (MERS-CoV) and Severe Acute
Respiratory Syndrome coronavirus (SARS-CoV), as fatal human CoV diseases, has induced significant
interest in the medical field. The novel coronavirus disease (COVID-19) is an infectious disease
caused by a novel strain of coronavirus (SAR-CoV-2). The SARS-CoV2 outbreak has been
evolved in Wuhan, China, in December 2019, and identified as a pandemic in March 2020, resulting
in 53.24 M cases and 1.20M deaths worldwide.
SARS-CoV-2 main proteinase (MPro), a key protease of CoV-2, mediates viral replication and transcription.
SARS-CoV-2 MPro has been emerged as an attractive target for SARS-CoV-2 drug design
and development. Diverse scaffolds have been released targeting SARS-CoV-2 MPro. In this review,
we culminate the latest published information about SARS-CoV-2 main proteinase (MPro) and reported
