In this study, a new series of more than 60 quinoline derivatives has been synthesized and evaluated against Mycobacterium tuberculosis (H37Rv). Apart from the SAR exploration around the initial hits, the optimization process focused on the improvement of the physicochemical properties, cytotoxicity, and metabolic stability of the series. The best compounds obtained exhibited MIC values in the low micromolar range, excellent intracellular antimycobacterial activity, and an improved physicochemical profile without cytotoxic effects. Further investigation revealed that the amide bond was the source for the poor blood stability observed, while some of the compounds exhibited hERG affinity. Compound 83 which contains a benzoxazole ring instead of the amide group was found to be a good alternative, with good blood stability and no hERG affinity, providing new opportunities for the series. Overall, the obtained results suggest that further optimization of solubility and microsomal stability of the series could provide a strong lead for a new anti-TB drug development program.
