| 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 |
