Many drugs have been introduced for the treatment of neo-coronavirus pneumonia; for example tetracycline and doxycycline can act as inhibitors of ACE2 binding (28); niclosamide can inhibit RNA viruses during the post-entry phase of viral RNA replication and also exhibits anti-inflammatory activity (189); chloroquine reduces the production of cytokines and damage-associated molecular patterns by interfering with the innate immune pathways of multiple immune cells, thus preventing experimental sepsis and infectious shock (190, 191). The gene discussed is ACE2; the disease is Shock.
