Confirmation of DDUG inhibition of M.tb growth in infected THP-1 cells. Dose-dependent inhibition of M.tb:THP-1 intracellular growth by novel and established compounds, normalized to 1% DMSO negative control (0% inhibition) (A). CI, confidence interval. DDUG inhibition of M.tb growth in infected bone marrow derived macrophages (BMDM) cells (B). Dose-dependant cell loss of THP-1 (red) and bone marrow derived macrophages (BMDM) cells (green) (C). M.tb intracellular growth inhibition by RNAi suppression of the DDUG target, CHK2, interpolated to the negative control (1% DMSO) set at 0% inhibition and the positive control (4 μM bedaquiline) defined as 100% inhibition (D). Each data point is an average of 4 independent trials, and error bars are the SEM.
