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].
