The mechanism of ester reduction is similar to that of acid chloride reduction in that a hydride ion first adds to the carbonyl group, followed by elimination of alkoxide ion to yield an aldehyde.

They work by targeting peptidoglycan in bacteria. This class of antibiotics is widely used to treat bacterial infections, though resistance through β-lactamase enzymes poses a significant challenge. Modified versions, such as methicillin, help overcome resistance. These antibiotics play a vital role in modern medicine.
