Antimycobacterial agent-1 (compound 33) demonstrates potent antimycobacterial activity against Mycobacterium tuberculosis H37Ra, with a minimal inhibitory concentration (MIC) value of 1 μg/ml. Notably, antimycobacterial agent-1 exhibits low cytotoxicity in normal cells, as evidenced by an IC50 value of 143.2 μg/ml in Vero cells [1].
Antibacterial agent 118 (also known as compound 20) is a potent antimycobacterial compound with activity against various mycobacterial strains, including Mtb H37Ra, M. aurum, M. smegmatis, Mtb H37Rv, and M. avium. The minimum inhibitory concentration (MIC) values for Antibacterial agent 118 against these strains are 40.7 μM, 10.2 μM, 163.0 μM, 62.5 μM, and 62.5 μM, respectively. This compound holds potential for tuberculosis research [1].
