Study Notes
Antimicrobial Agents
- Polymyxins and polyenes disrupt cell membrane integrity, ultimately leading to cell lysis.
- Sulfonamides act as competitive inhibitors of essential metabolites biosynthesis, specifically inhibiting the enzyme dihydropteroate synthase.
- Quinolones and rifampicin inhibit nucleic acid synthesis, targeting DNA gyrase and RNA polymerase, respectively.
- Aminoglycosides, macrolides, and tetracyclines inhibit protein synthesis, binding to the 30S and 50S ribosomal subunits.
