Drug-like Inhibitor shows Promise in Preventing Flu

Posted by in category: biotech/medical

Currently available flu medications only target the virus after it has already established an infection, but what if a drug could prevent infection in the first place? Now, scientists at Scripps Research and the Albert Einstein College of Medicine have designed drug-like molecules to do just that, by thwarting the first stage of influenza infection.

The drug-like inhibitors block the virus from entering the body’s respiratory cells — specifically, they target hemagglutinin, a protein on the surface of type A influenza viruses. The findings, published in the Proceedings of the National Academy of Sciences on May 16, 2024, represent an important step forward in developing a drug that can prevent influenza infection.

“We’re trying to target the very first stage of influenza infection since it would be better to prevent infection in the first place, but these molecules could also be used to inhibit the spread of the virus after one’s infected,” says corresponding author Ian Wilson, DPhil, the Hansen Professor of Structural Biology at Scripps Research.
