Flashcards

Cell Wall Inhibitors

Drugs that inhibit cell wall synthesis, targeting rapidly growing bacteria.

Beta-lactam Antibiotics

A class of antibiotics possessing a critical beta-lactam ring structure, inhibiting bacterial cell wall synthesis.

Vancomycin

A powerful antibiotic that inhibits cell wall synthesis, particularly effective against Gram-positive bacteria.

Cell Wall Inhibitor Effectiveness

Cell wall inhibitors are most effective when bacteria are actively growing and dividing.

Study Notes

Cell Wall Inhibitors

  • Inhibitors of cell wall synthesis are most effective against actively proliferating microorganisms.
  • These inhibitors have little to no effect on bacteria that are not growing and dividing.
  • Important examples of cell wall inhibitors include beta-lactam antibiotics (named after their beta-lactam ring) and vancomycin.
