ABSTRACT
Recurrent epidemics of coronaviruses have posed significant threats to human life and health. The mortality rate of patients infected with the Middle East Respiratory Syndrome Coronavirus (MERS-CoV) is 35 %. The main protease (Mpro) plays a crucial role in the MERS-CoV life cycle, and Mpro exhibited a high degree of conservation among different coronaviruses. Therefore inhibition of Mpro has become an effective strategy for the development of broad-spectrum anti-coronaviral drugs. The inhibition of SARS-CoV-2 Mpro by the anti-tumor drug carmofur has been revealed, but structural studies of carmofur in complex with Mpro from other types of coronavirus have not been reported. Hence, we revealed the structure of the MERS-CoV Mpro-carmofur complex, analysed the structural basis for the binding of carmofur to MERS-CoV Mpro in detail, and compared the binding patterns of carmofur to Mpros of two different coronaviruses, MERS-CoV and SARS-CoV-2. Considering the importance of Mpros for coronavirus therapy, structural understanding of Mpro inhibition by carmofur could contribute to the design and development of novel antiviral drugs with safe and broad-spectrum efficacy.
