Looking at Healthline.com article “Treatment for Coronavirus Disease (COVID-19)” this is quite interesting:

Chinese scientists have a drug called APNO1 which may help with the coronavirus but the FDA hasn’t approved of its use yet because it hasn’t passed enough clinical trials. APNO1 is supposed to help coronavirus patients who have had the virus affect their lungs and made it difficult to breathe by alleviating the symptoms. Since the virus uses a protein called ACE-2 to affect cells, that drug (APNO1) seeks to block some protein receptors in the body so that the virus is limited to getting into the cells and affecting them. But it’s still in clinical trials and currently there isn’t a vaccine or treatment for coronavirus yet.
