Antitubercular agent-16 (Compound 5q) is a potent antitubercular agent exhibiting high efficacy against various strains of M. tuberculosis, including H37Rv, CF16, CF61, CF76, CF152, and CF161, with MIC 90 values ranging from 0.40 to 23.51 μg/mL. Notably, Antitubercular agent-16 demonstrates minimal cytotoxicity towards macrophages and pulmonary fibroblasts, further highlighting its potential as a therapeutic agent [1].
Antitubercular agent-24 (Compound 1) exhibits anti-tubercular properties against M. tuberculosis H37Rv. It demonstrates an extracellular IC50 of 0.83 μM and an intracellular IC50 of 0.17 μM [1].
Antitubercular agent-12 (Compound 2c) is a highly effective antitubercular agent, with a MIC (Minimum Inhibitory Concentration) value of 1.439 μg/mL. Notably, Antitubercular agent-12 exhibits significantly reduced cytotoxicity, reflected by a CC50 (50% Cytotoxic Concentration) value of 57.34 μg/mL [1].
