Mt KARI-IN-1

Mt KARI-IN-1 is a lead compound that demonstrates strong inhibitory activity towards Mycobacterium tuberculosis ketol-acid reductoisomerase (Mtb KARI), with a Ki value of 3.06 μM [1].

Mt KARI-IN-4 (compound 5c) is a highly effective inhibitor of Mycobacterium tuberculosis ketol-acid reductoisomerase (Mtb KARI), demonstrating a Ki value of 5.48 μM. Additionally, Mt KARI-IN-4 displays inhibitory properties against Mtb H37Rv, with a minimum inhibitory concentration (MIC) of 0.78 μM. Importantly, this compound exhibits low levels of cytotoxicity, as evident from its half-maximal inhibitory concentration (IC 50 ) value of over 72 μg mL against human embryonic kidney cells (HEK) [1].

Mt KARI-IN-2 (compound 5b) is a highly effective inhibitor of Mycobacterium tuberculosis ketol-acid reductoisomerase (Mtb KARI), with a Ki value of 2.02 μM. This compound also exhibits inhibitory activity against Mtb H37Rv, with a MIC value of 0.78 μM. Moreover, Mt KARI-IN-2 demonstrates low cytotoxicity, as evidenced by a HEK IC 50 greater than 86 μg mL [1].
