Remdesivir (GS-5734) is a 1′-cyano-substituted adenosine nucleotide analogue prodrug that shows broad-spectrum antiviral activity against several RNA viruses. Upon the administration and metabolism of this drug, the virus incorporates this nucleoside analogue by accident in its growing RNA strands while it attempts to replicate inside a host cell. … Remdesivir (RDV) is clin. Share. Remdesivir, also known as Veklury or GS-5734, is a 1’-cyano-substituted adenosine nucleotide analog prodrug that shows broad-spectrum antiviral activity. Subsequent evaluation by numerous virology laboratories demonstrated the ability of remdesivir to inhibit coronavirus replication, including SARS-CoV-2. Remdesivir isn’t a vaccine, and so it can’t prevent infection; instead, it works by attacking the virus once it is already spreading inside the body. Remdesivir is a broad-spectrum antiviral drug that has also been clinically evaluated for the treatment of Ebola virus disease. The compound undergoes a metabolic mechanism, activating nucleoside triphosphate metabolite for inhibiting viral RNA polymerases. Previous article in issue; Next article in issue; Key Words.
