lincosamide antibiotic iboxamycin Iboxamycin is a fully synthetic lincosamide antibiotic. Like other lincosamides, it selectively targets the bacterial ribosome and prevents elongation of the peptide chain. Iboxamycin has been shown to be effective against bacterial strains otherwise resistant to licosamide antibiotics. antibiotic_resistance PubChem:156613433 ARO:3007636
