For decades, researchers have wanted to leverage these peptides’ natural virus-combat skills into new drug therapies. But peptides are vulnerable to enzymes that rapidly break them down in a way that robs them of their therapeutic properties. “Because of their vulnerability to enzymatic breakdown, peptides are not ideal drugs. They’re expensive to produce, and yet they must be given in large doses because they disintegrate so quickly in the body,” said Annelise Barron, an associate professor of bioengineering at Stanford School of Engineering. But now, Barron and a team of scientists, including researchers at Berkeley Lab’s [URL='https://foundry.lbl.gov/']Molecular Foundry[/URL], have created peptide-like molecules called “peptoids” that can inactivate viruses. The researchers believe that the technology could make possible an emerging category of antiviral drugs that could treat everything from herpes and COVID-19 to the common cold.
