CDCA7L and lung disorder: 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.
