Researchers have found that a small chemical compound called K22 can interfere with the ability of coronaviruses to use the internal membranes of host cells for their own replication. Although it’s still a very long way from being a drug, the fact that the molecule shows activity against a wide range of coronaviruses – including middle east respiratory syndrome (MERS) – is of great interest to those studying these viruses.
