Abstract
Tuberculosis, also called TB, is currently a major health hazard due to
multidrug-resistant forms of bacilli. Global efforts are underway to
eradicate TB using new drugs with new modes of action, higher activity, and
fewer side effects in combination with vaccines. For this reason, unexplored
new sources and previously explored sources were examined and around 353
antimycobacterial compounds (Nat Prod Rep 2007; 24: 278–297) [7] have been previously reported. To develop
drugs from these new sources, additional work is required for preclinical
and clinical results. Since ancient times, different plant part extracts
have been used as traditional medicines against diseases including
tuberculosis. This knowledge may be useful in developing future powerful
drugs. Plant natural products are again becoming important in this regard.
In this review, we report 127 antimycobacterial compounds and their
antimycobacterial activities. Of these, 27 compounds had a minimum
inhibitory concentration of < 10 µg/mL. In some cases, the mechanism of
activity has been determined. We hope that some of these compounds may
eventually develop into effective new drugs against tuberculosis.
