Remdesivir is a nucleoside analogue and is an RNA-dependent RNA polymerase (RdRp) inhibitor. It can synthesize anti-virus by inhibiting viral nucleic acid. The current Chemicalbook bed study for Ebola virus infection has reached stage II. Mice infected with MERS performed much better after receiving this combination therapy, with reduced virus replication and improved lung function. Recent studies have shown that redoxivir has a certain effect on the inhibition of new coronavirus.
