Webβ-lactam antibiotics are bactericidal, and act by inhibiting the synthesis of the peptidoglycan layer of bacterial cell walls. The peptidoglycan layer is important for cell wall structural integrity, [6] especially in Gram-positive organisms, being the outermost and primary component of the wall. Cell wall synthesis inhibitors include antibiotics of class β- lactams and Glycopeptides. Β- lactam antibiotics consist of Penicillins, Cephalosporins, Monobactams, and Carbapenem. Glycopeptides include Vancomycin and Teicoplanin which are the most commonly used antibiotics of this class. … See more The affinity of the drug, its permeability, and stability determines the activity against bacteria.
