Lufotrelvir (Cat.No:I031110) is a small molecule prodrug that targets the 3CLpro protease (Mpro), which is used by viruses like SARS-CoV-2 to assemble and multiply. Once administered through intravenous infusion, the compound is cleaved into PF-00835231 to exert its anti-viral effects. Lufotrelvir, developed by Pfizer, was first identified during the SARS outbreak in 2002-2003; it was subsequently shelved as the outbreak was controlled. Now, it is being tested regarding the novel SARS-CoV-2 virus, including studies in conjunction with Remdesivir to treat COVID-19 infection; in vitro data showed synergistic effects on articles published on preprint servers.
