6. Nitrobenzene derivative: Chloramphenicol.
7. Aminoglycosides: Streptomycin, Gentamicin, Amikacin, eomycin, etc.
8. Macrolide antibiotics: Erythromycin, Clarithromycin.
Azithromycin, etc.
9. Lincosamide antibiotics: Lincomycin, Clindamycin.
I 0. Glycopeptide antibiotics: Vancomycin, Teicoplanin.
11 . Oxazolidinone: Linezolid.
12. Polypeptide antibiotics: Polymyxin-B, Colistin, Bacitracin, Tyrolhricin.
13. Nitrofuran derivatives: itrofurantoin, Furazolidonc.
14. Nitroimidazoles: Metronidazole, Tinidazole, etc.
