Natural Penicillins. David B. Beta-lactam ring interferes with final stage of cell wall synthesis by binding to peptidoglygan, bacterial enzyme that catalyzes cell wall strength. Bacteriocidal activity against many gram-positive organisms, as well as some spirochetes and fungi. Is susceptible to penicillinase (beta-lactamase).
