---|---|---|---|---|---|
D-cycloserine | Cell wall synthesis; blocks addition of dipeptide to UDP-NAM - second step so no PEP attaches
🗑
|
||||
Bacitracin | cell wall synthesis; blocks dephosphoralizatoin of bactoprenol phosphate- middle step transports ppg monomers across cell membrane
🗑
|
||||
PCN | cell wall synthesis; beta-lactamases; last step of binding to transpeptidase to reform the peptide cross links
🗑
|
||||
Cephalosporin | cell wall synthesis; beta-lactamases; last step of binding to transpeptidase to reform the peptide cross links
🗑
|
||||
cephamycin | cell wall synthesis
🗑
|
||||
fosfomycin | inhibits cell wall synthesis; inhibits phosphoenopyruvate transferase adn prevents formation of NAM -- first step does not occur
🗑
|
||||
metronidazole | disrupts DNA helical structure under anaerobic conditions
🗑
|
||||
Quinolones, flouroquinolones | inhibits DNA gyrase or topoisomerase
🗑
|
||||
rifampin | binds to RNA polymerase
🗑
|
||||
polymyxins | interact with phospholipids
🗑
|
||||
macrolides, erythromycin, choramphenicol | 50S inhibitors; translation-protein synthesis
🗑
|
||||
tetracyclines, aminoglycosides, streptomycin | 30S inhibitors; translation-protein synthesis
🗑
|
||||
Linezolid | initiating complex blocked;
🗑
|
||||
sulfonamides | folate antagonist; blocks synthesis of dihydropteroic acid
🗑
|
||||
trimethoprim | folate antagonist; blocks synthesiss of tetrahydrofolate
🗑
