A class of antibiotics heralded as an essential future weapon against drug-resistant superbugs passed an important test. There’s now evidence that they can be used to treat serious infections in live animals (in vivo) without being toxic.
Researchers created simplified, synthetic versions of teixobactin, a protein produced by certain dirt-loving bacteria that was first discovered in 2015. They tested the teixobactin in lab mice whose eyes were infected with one of several germs, including antibiotic-resistant strains of Staphylococcus aureus and Enterococcus.

The findings were published in January in the Journal of Medicinal Chemistry.
