Possible new antivirals against COVID-19, herpes

In addition to antibodies and white blood cells, the immune system deploys peptides to fight viruses and other pathogens. Synthetic peptides could reinforce this defense but don't last long in the body, so researchers are developing stable peptide mimics. Today, scientists report success in using mimics known as peptoids to treat animals with herpes virus infections. These small synthetic molecules could one day cure or prevent many kinds of infections, including COVID-19.
