- beta-lactam antibiotic: A broad class of antibiotics that inhibit cell wall synthesis, consisting of all antibiotic agents that contains a β-lactam nucleus in their molecular structures. This includes penicillin derivatives (penams), cephalosporins (cephems), monobactams, and carbapenems.

Because human cells do not make peptidoglycan, this mode of action is an excellent example of selective toxicity. Antibiotics that inhibit the cell wall biosynthesis of bacteria include the penicillins (including ampicillin, amoxicillin, and methicillin), cephalosporins, vancomycin, and bacitracin.
Aug 22, 2023 · Clovibactin, a new antibiotic isolated from soil bacteria, blocks bacterial cell wall synthesis by targeting essential peptidoglycan precursors, allowing it to kill drug-resistant bacterial pathogens without detectable resistance.
Jul 11, 2023 · Inhibition of bacterial cell wall synthesis by antibiotics such as β-lactams is thought to cause explosive lysis through loss of cell wall integrity. However, recent studies on a wide...

Aug 23, 2022 · The transglycosylation reaction is the target of three different antibiotics: Moenomycin (Sect. 3.3.3.2), Mercacidin, a lantibiotic, (Sect. 3.3.3.3) and Vancomycin (Sect. 3.3.3.4). The final step in cell wall biosynthesis is the cross-linking of the peptidoglycan strands by transpeptidation.
Vancomycin is a glycopeptide antibiotic used for the treatment of serious infections by Gram-positive pathogens. Vancomycin inhibits cell wall biosynthesis by targeting the d-Ala-d-Ala terminus of peptidoglycan (PG).
