KKL-10 is a small-molecule inhibitor of bacterial ribosome rescue that exhibits broad-spectrum antimicrobial activity against bacteria grown in liquid culture.

This alpha-helical antimicrobial OV-1 ovispirin peptide derived from SMAP29 peptide.It was found to inhibit several antibiotic-resistant bacterial strains including mucoid and nonmucoid Pseudomonas aeruginosa.

Ceforanide is a second-generation cephalosporin antibiotic with bactericidal activity. Ceforanide causes inhibition of bacterial cell wall synthesis by inactivating penicillin binding proteins (PBPs) thereby interfering with the final transpeptidation step required for cross-linking of peptidoglycan units which are a component of the cell wall.
