Objectives: The emergence of resistant strain has aggravated the tuberculosis situation in the world, running out of control and hard to fight. We evaluate forty new quinoline analogues against sensitive and resistant Mycobacterium tuberculosis (Mtb). Methods: The compounds were obtained via synthesis and evaluated against sensitive strain ATCC 27294. Selected compounds were evaluated against resistant strains SR 2571/0215 and T113/09, using the MABA method. The more active compounds were selected for their potential cytotoxic activity against human macrophage cells. Results: Twenty-nine compounds displayed activity against sensitive strain, and thirteen were active against resistant strains. Against sensitive strain, the most promising compounds were 4c and 4d (MIC = 9 and 12 μM, respectively). Against resistant strains, the compounds 4a, 4d displayed the best results (MIC = 4 and 5 μM, respectively). The active compounds 4a, 4d, 6d, 7c, 8d, and 10d were non-cytotoxic to the host cells at concentrations near to the MIC. The non-cytotoxic compound 4d was the most potent against resistant and sensitive Mtb. Conclusion: These findings contribute to relevant information and perspectives in search of new bioactive compounds against sensitive and resistant TB. Resistant strains have turned tuberculosis a severe disease in the world.

Inspired by quinine and its analogues, we designed, synthesized, and evaluated two series of quinoline small molecular compounds (a and 2a) and six series of quinoline derivatives (3a-f) for their antifungal activities. The results showed that compounds 3e and 3f series exhibited significant fungicidal activities. Significantly, compounds 3f-4 (EC50 = 0.41 μg/mL) and 3f-28 (EC50 = 0.55 μg/mL) displayed the superior in vitro fungicidal activity and the potent in vivo curative effect against Sclerotinia sclerotiorum. Preliminary mechanism studies showed that compounds 3f-4 and 3f-28 could cause changes in the cell membrane permeability, accumulation of reactive oxygen species, loss of mitochondrial membrane potential, and effective inhibition of germination and formation of S. sclerotiorum sclerotia. These results indicate that compounds 3f-4 and 3f-28 are novel potential fungicidal candidates against S. sclerotiorum derived from natural products.
