Lanopepden (GSK1322322) had an MIC90 of 1 μg/ml against M. catarrhalis and 4 μg/ml against H. influenzae, with 88.8% of beta-lactamase-positive strains showing growth inhibition at that concentration. All S. pneumoniae strains were inhibited by ≤ 4 μg/ml of GSK1322322, with an MIC90 of 2 μg/ml. GSK1322322 was very potent against S. pyogenes strains, with an MIC90 of 0.5 μg/ml, irrespective of their macrolide resistance phenotype. It was also active against S. aureus strains regardless of their susceptibility to methicillin, macrolides, or levofloxacin, with an MIC90 of 4 μg/ml in all cases.
