Beta-lactam antibiotics are a broad class of bactericidal agents containing a characteristic four-sided ring, including penicillins, cephalosporins, carbapenems, and monobactams. They treat infections by binding to penicillin-binding proteins (PBPs), inhibiting cell wall synthesis, and causing bacterial lysis. Key challenges include bacterial resistance via beta-lactamase enzymes and hypersensitivity reactions. 

Mechanism of Action: These antibiotics inhibit the final step of bacterial peptidoglycan
