Scientists revive a powerful antibiotic that superbugs had defeated
Scientists have used a chemical library to identify an adjuvant that restores the effectiveness of vancomycin against resistant superbugs. By targeting a specific bacterial enzyme, the researchers successfully weakened the bacteria's defenses.
Why it matters
This approach offers a new way to combat antibiotic resistance, potentially saving existing drugs from becoming obsolete against dangerous pathogens.
Antibiotic resistance is becoming one of the most serious dangers facing modern medicine. As bacteria evolve, drugs that once worked reliably can lose their effectiveness. This makes common infections harder to treat and can increase the risks associated with routine surgery, cancer care, and other medical procedures.
Researchers worldwide are searching for ways to stay ahead of these rapidly changing microbes. One promising strategy is not to invent a completely new antibiotic, but to help existing drugs work again. This is the idea behind antibiotic adjuvants, which are companion molecules that do not kill bacteria directly but instead restore the power of antibiotics.
Building New Molecules to Speed Drug Discovery
Professor John Moses and his team at Cold Spring Harbor Laboratory (CSHL) have spent years developing chemical reactions that can make the drug discovery process faster and more efficient.
