Figure 2. Correlation of PK parameters (Cmax, AUC) with in vivo efficacy in mice for bicyclic 4-nitroimidazole analogs in total plasma concentration (A), free plasma concentration (B) and total lung concentration (C).
Each data point represents Δ mean log lung CFU reduction compared to untreated controls (mean value ± SEM from 5 animals). rs is the Spearman’s rank correlations coefficient.
