In the first study, a series of HR1 peptides was developed by molecular docking to inhibit HR1/HR2‐mediated membrane fusion between the MERS‐CoV and host cells.[72] Further, the nanoparticle‐based vaccine inhibited viral infection, was immunogenic and prevented the induction of undesirable lung disease in immunized human DPP4 enzyme transgenic mice.[73] Recently, preliminary results with the virucidal effect of TNP against the HCoV‐NL63 and HCoV‐OC43 by photoactive TNP deposited on glass coverslips using UVC radiation. This evidence concerns the gene CDCA7L and viral infectious disease.
