Abstract
The Middle East respiratory syndrome coronavirus (MERS-CoV) has remained a public health concern since it first emerged in 2012. Although many potential treatments for MERS-CoV have been developed and tested, none have had complete success in stopping the spread of this deadly disease. MERS-CoV replication comprises attachment, entry, fusion and replication steps. Targeting these events may lead to the creation of medications that effectively treat MERS-CoV infection.
This review updates the research on the development of inhibitors of MERS-CoV. The main topics are MERS-CoV‒related proteins and host cell proteins that are involved in viral protein activation and infection.
Research on discovering drugs that can inhibit MERS-CoV started at a slow pace, and although efforts have steadily increased, clinical trials for new drugs specifically targeting MERS-CoV have not been extensive enough. The explosion in efforts to find new medications for the SARS-CoV-2 virus indirectly enhanced the volume of data on MERS-CoV inhibition by including MERS-CoV in drug assays. The appearance of COVID-19 completely transformed the data available on MERS-CoV inhibition. Despite the fact that new infected cases are constantly being diagnosed, there are currently no approved vaccines for or inhibitors of MERS-CoV.
