Induction of iniBAC or recA bioluminescent reporter in response to antimycobacterial agents with unknown MoAs at concentrations ranging between 0.125-4× MIC, monitored over 9 days. For PiniB-LUX, INH was used as the positive control at a concentration of 0.39 µM (1× MIC); CIP was used as the negative control. The iniBAC response is shown for 127-09, 127-17, 127-21, 127-23, 127-13, 127-15, MN-6925, and the controls. For PrecA-LUX, CIP was used as the positive drug control at 3.13 µM (2× MIC), although concentrations in the range of 0.2–6.25 µM (0.125-4× MIC) all gave similar luminescence profiles; INH was the negative control. The recA response is shown for 127-11, 127-13 and the controls. RLU, relative luminescence unit.
