SCH79797 significantly improves survival, lung injury and inflammation in murine E. coli pneumonia. SCH79797 at 10 μM was determined to be the most effective dose when given as a treatment 6 h after infection (a; n = 17–19 per group, *P < 0.05 for 10 μM SCH79797, SCH 10, versus PBS; 100μM SCH79797 (SCH 100) provided no survival advantage versus PBS). H&E staining of lungs demonstrated less lung injury in mice treated with SCH79797 10 μM (SCH) at 24 h post-infection (b and c; n = 3 lungs per group for lung injury score analysis, *P < 0.05 for SCH- versus PBS-treated groups, data as mean ± SD). BAL at 24 h showed reduced inflammatory cell influx (d), reduced bacterial burden (e) and a trend towards a reduction in both inflammatory cytokine levels (f) and vascular permeability (g) with SCH treatment (n = 6 per group for all analyses, *P < 0.05 and P = 0.16 for macrophage inflammatory protein-2 (MIP-2) concentrations and P = 0.055 for albumin concentrations, data as mean ± SD).
