title: Determination of disk diffusion and MIC quality control ranges for GSK1322322, a novel peptide deformylase inhibitor.
abstract: GSK1322322 is a novel peptide deformylase inhibitor in the early phase of development for treatment of complicated bacterial skin and skin structure infection and hospitalized community-acquired pneumonia. This quality control (QC) study was performed to establish broth microdilution and disk diffusion QC ranges for strains Staphylococcus aureus ATCC 29213 (MIC range, 1 to 4 μg/ml), Haemophilus influenzae ATCC 49247 (MIC and disk diffusion zone diameter ranges, 0.5 to 4 μg/ml and 20 to 28 mm, respectively), Streptococcus pneumoniae ATCC 49619 (MIC and disk diffusion zone diameter ranges, 0.12 to 0.5 μg/ml and 23 to 30 mm, respectively), and S. aureus ATCC 25923 (disk diffusion zone diameter range, 18 to 26 mm). These ranges are crucial for evaluating GSK1322322 potency as it progresses through clinical trials.
