New structural classes of antituberculosis agents.

Area of Science:

• Medicinal Chemistry
• Infectious Diseases
• Drug Discovery

Background:

• Tuberculosis (TB) remains a major global health threat, exacerbated by the rise of multidrug-resistant (MDR) and extensively drug-resistant (XDR) strains.
• Existing treatments face challenges including long therapy durations, toxicity, and the rapid development of resistance by Mycobacterium tuberculosis.
• Novel therapeutic strategies are crucial to overcome the limitations of current anti-TB drugs.

Purpose of the Study:

• To review and categorize new structural classes of synthetic anti-TB agents reported in the literature over the 10 years following 2005.
• To identify compounds with potentially novel mechanisms of action to combat drug-resistant TB.
• To provide a comprehensive overview of recent advancements in the search for new anti-TB drug scaffolds.

Main Methods:

• Systematic literature review of scientific reports on synthetic anti-TB agents published between 2006 and 2015.
• Classification of newly discovered compounds into distinct structural classes based on their chemical scaffolds.
• Analysis of reported biological activities and potential mechanisms of action.

Main Results:

• Identification and categorization of 38 distinct structural classes encompassing 368 novel synthetic compounds with anti-TB potential.
• The reviewed compounds represent a shift towards exploring new molecular scaffolds and potential novel drug targets.
• The findings underscore the ongoing efforts to develop effective treatments against drug-susceptible and drug-resistant TB.

Conclusions:

• The exploration of new structural classes of synthetic agents is a promising avenue for developing next-generation anti-TB therapies.
• These novel compounds may offer alternative mechanisms of action, potentially circumventing existing resistance pathways.
• Continued research into these new scaffolds is essential for addressing the global challenge of tuberculosis.
