Benzimidazole-core as an antimycobacterial agent

Area of Science:

• Medicinal Chemistry
• Organic Chemistry
• Pharmacology

Background:

• Tuberculosis (TB), caused by Mycobacterium tuberculosis (Mtb), is a leading cause of bacterial infection-related deaths globally.
• India faces a significant burden, accounting for a substantial portion of global TB cases and deaths.
• There is an urgent need for improved anti-TB therapies with novel targets and mechanisms of action.

Purpose of the Study:

• To review recent advancements in benzimidazole derivatives as potential anti-TB agents.
• To explore the structural features of benzimidazoles responsible for their anti-TB activity.
• To compile synthetic approaches for designing next-generation anti-TB drug candidates.

Main Methods:

• Literature review of published reports on benzimidazole derivatives with anti-TB activity.
• Analysis of structure-activity relationships (SAR) for anti-TB efficacy.
• Compilation of synthetic methodologies for key benzimidazole scaffolds.

Main Results:

• Benzimidazole derivatives, particularly 2,5- and 2,6-disubstituted analogs, exhibit significant anti-TB potential.
• Specific structural features of benzimidazoles are crucial for their efficacy against Mycobacterium tuberculosis.
• Various synthetic strategies have been employed to generate diverse benzimidazole libraries.

Conclusions:

• Benzimidazoles represent a privileged scaffold for the development of novel anti-TB drugs.
• Understanding the SAR of these compounds is key to designing more effective and safer anti-TB candidates.
• This review provides valuable insights for medicinal chemists in the ongoing fight against tuberculosis.
