Class/MOA? - Vancomycin
Cell Wall Inhibitor - Glycoprotein - D-ALA-D-ALA Transglycosylation inhibitor
Effective only against gam positive bacteria
Class/MOA? - Fosfomycin
Cell Wall Inhibitor - Enolpyruvyl transferase inhibitor (_F_osfomycin acts on the _F_irst part of cell wall synthesis)
Class/MOA? - Gentamicin
Protein Synthesis Inhibitor - Aminoglycoside - Bind 30S, preventing AUG start codon ?. OR?. Punches a hole in the outer membrane (thought to give it its bactericidal effect)
more effective against aerobes, takes energy to enter the cell

Protein Synthesis Inhibitor - Lincosamides - 23S of 50S - Peptidyl Transfer - Prevents growing of protein
Class/MOA? - Linezolid
Protein Synthesis Inhibitor - OxaZOLIDinones -Drug of Last Resort, MOA not mentioned, but it binds a unique portion of 50S
Class/MOA? - Doxycycline
Protein Synthesis Inhibitor - TetraCYCLINES -16S of 30S - prevents growing of protein
Class/MOA? - Tigecycline
Protein Synthesis Inhibitor - TetraCYCLINES -16S of 30S - prevents growing of protein
Class/MOA? - Mupirocin
