The neurotransmitter receptor blockers chlorpromazine (15), promethazine (16), and fluphenazine (17; Figure 7), were reported to inhibit MERS‐CoV and SARS‐CoV‐1 most probably by impeding S protein‐induced fusion. 103  Chlorpromazine, a clathrin‐mediated viral entry inhibitor, was already described to inhibit human CoV‐229E, hepatitis C virus, infectious bronchitis virus, as well as mouse hepatitis virus‐2 (MHV2). 104 ,  105 ,  106 ,  107 ,  108
