Clever chemistry and a new class of antibiotics

A more rigid key in the lock

A new class of molecules called acyldepsipeptides — ADEPs — may provide a new way to attack bacteria that have developed resistance to antibiotics. Researchers at Brown and MIT have discovered a way to increase the potency of ADEPs by up to 1,200 times. Their findings appear in the Journal of the American Chemical Society.
