WebMechanism of action Cephalosporins were developed from cephalosporin C, a natural product of Cephalosporium acreminium. Cephamycins are related drugs derived from Streptomyces spp or are synthetic derivatives. These antibacterials are related structurally to benzylpenicillin and have a β-lactam ring.
Webmethicillin, also called meticillin, antibiotic formerly used in the treatment of bacterial infections caused by organisms of the genus Staphylococcus. Methicillin is a semisynthetic derivative of penicillin. It was first produced in the late 1950s and was developed as a type of antibiotic called a penicillinase-resistant penicillin—it contained a modification to the … WebPenicillin kills bacteria through binding of the beta-lactam ring to DD-transpeptidase, inhibiting its cross-linking activity and preventing new cell wall formation.
