Chloramphenicol | Unclassified(atypical)- Peptidyl Transferease inhibitor to inhibit protein synthesis |
Erythromycin | Macrolide- 50S ribosome subunit binding & used for protein synth inhibition- Aminoacyl translocation (tRNA-rRNA transfer) inhibition. |
Streptomycin | First Aminoglycoside- S12-protein of 30S ribosome subunit binding, interfering with formyl-methionyl-tRNA binding (--X protein synth) |
Sulphanilamide | Sulphonamide- Dihydropterate synthetase inhibitor (for folic acid synth) |
Tetracycline | Tetracycline family- binds to 16S-part of 30S ribosome subunit & reversibly inhibits aminoacyl tRNA from binding to the A-site |
Nystatin | Similar to Tetracyclines- Ergosterol-binding forms pores that lea to K+ loss & death. |
Ciprofloxacin | Fluoroquinolone- for both G-/+ Inhibits DNA Gyrase in G- & topoisomerase II/IV in G+. Inhibits DNA replication & reading. |
Clindamycin | |
Gentamicin | |
Trimethoprim | |
Fluoroquinolones | (Ciprofloxacin)- Inhibit DNA gyrase in G- or topoisomerase II/IV in G+. Inhibits DNA replication & reading. |
Lincosamides (class) | |
Macrolides | |
Aminoglycosides | |
Tetracyclines | |
Penicillin | Beta-lactam- DD-transpeptidase inhibition for peptidoglycan-crosslinking inhibition |
