Partial penicillin derivatives
WebPenicillin/penicillin derivatives antibiotics inhibit the formation of peptidoglycan cross-links in the bacterial cell wall, which is achieved through binding of the four-membered β-lactam ring of penicillin to the enzyme DD-transpeptidase. As a result, DD-transpeptidase cannot catalyze the formation of these cross-links, leading to an ...
