For decades, vancomycin has stood as one of medicine's last defenses against the most dangerous bacterial infections — yet resistance has steadily eroded its power, contributing to nearly five million deaths each year. Scientists at Scripps Research have now identified a way to restore that power, not by creating a new antibiotic, but by disabling a bacterial enzyme called SagA that allows resistant strains to evade the drug. A chemical compound, pghi-4, can pharmacologically silence this enzyme, reducing the vancomycin dose needed to kill resistant bacteria by as much as eightfold. In a time

Scripps researchers restore vancomycin's power against drug-resistant bacteria
Antibiotic resistance is linked to an estimated 4.7 million deaths worldwide annually, with vancomycin-resistant infections becoming increasingly common in hospital settings.

Public health
Consumers benefit from potential preservation of effective antibiotic treatments, reduced risk of untreatable infections, lower healthcare costs from avoiding expensive new drug development, and decreased hospital-acquired infection mortality rates.
Regulatory agencies may accelerate approval pathways for enzyme-inhibitor combination therapies. Policymakers may incentivize research into antibiotic resistance solutions through grants and patent extensions. Healthcare systems may update infection control protocols. International health organizations may incorporate this approach into antibiotic stewardship programs.
