Abstract
: 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 (M Pro ), a key protease of CoV-2, mediates viral replication and transcription. SARS-CoV-2 M Pro has been emerged as an attractive target for SARS-CoV-2 drug design and development. Diverse scaffolds have been released targeting SARS-CoV-2 M Pro . In this review, we culminate the latest published information about SARS-CoV-2 main proteinase (M Pro ) and reported inhibitors.
