Area of Science:

  • Medicinal Chemistry
  • Microbiology
  • Natural Products Chemistry

Background:

  • Tuberculosis (TB) remains a leading infectious cause of death globally, claiming over two million lives annually.
  • The emergence of multi-drug resistant Mycobacterium tuberculosis necessitates novel therapeutic strategies.
  • No new antitubercular agents with novel mechanisms of action have been developed in over three decades.

Purpose of the Study:

  • To review recent findings on plant-derived terpenoids with antimycobacterial activity.
  • To identify structural features crucial for activity against Mycobacterium tuberculosis.
  • To explore potential new leads for antituberculosis drug development.

Main Methods:

  • Literature review of scientific reports on plant-derived terpenoids.

Related Experiment Videos

  • Analysis of in vitro bioassay data against Mycobacterium tuberculosis.
  • Examination of structure-activity relationships for terpenoids, analogs, and derivatives.

    • Main Results:

    • Various plant-derived terpenoids, including mono-, sesqui-, di-, and triterpenes, as well as sterols, exhibit moderate to high in vitro activity against Mycobacterium tuberculosis.
    • Specific structural characteristics of these compounds are essential for their antimycobacterial efficacy.
    • Semisynthetic derivatives also show promising activity.

    Conclusions:

    • Plant-derived terpenoids represent a valuable source of novel antitubercular leads.
    • Further investigation into these compounds could lead to the development of urgently needed drugs against drug-resistant TB.
    • Structure-activity relationship studies are key to optimizing antimycobacterial potential.
