Beta-lactam antibiotics represent a crucial class of antimicrobials renowned for their efficacy in combating bacterial infections. This group includes penicillins, cephalosporins, carbapenems, and monobactams, all sharing a common beta-lactam ring structure. Mechanistically, these antibiotics target bacterial cell walls by inhibiting enzymes involved in peptidoglycan synthesis. Penicillins, the pioneering members of this class, exert their antimicrobial action by binding to penicillin-binding proteins (PBPs), disrupting cell wall formation, and inducing bacterial lysis. Cephalosporins, displaying a broader spectrum, act similarly by interfering with cell wall synthesis but offer resistance against certain beta-lactamases.
