Brequinar: A potential treatment for COVID-19 and beyond

Brequinar blocks de novo pyrimidine biosynthesis, which is essential for DNA and RNA synthesis. In vitro and in vivo studies have shown that brequinar has potent antiviral activity against a wide range of viruses, including SARS-CoV-2, the novel coronavirus that causes COVID-19. Because brequinar acts on the host cell, it has the potential to deliver mutation-resistant antiviral activity either as a standalone therapy or combined to complement and enhance direct-acting antiviral drugs, such as nucleoside analogs. Clear Creek Bio is focused on rapidly developing brequinar as a potential treatment for COVID-19 and to establish it as a broad-spectrum antiviral to be available in advance of future outbreaks for pandemic preparedness.
