Fluoroquinolone derivatives and their anti-tubercular activities

Area of Science:

• Medicinal Chemistry
• Microbiology
• Pharmacology

Background:

• Tuberculosis (TB) remains a leading cause of death globally, with latent Mycobacterium tuberculosis (MTB) infection affecting one-third of the population.
• Emerging virulent MTB strains and HIV co-infection necessitate novel, potent anti-TB drugs with favorable ADME profiles.
• Fluoroquinolones (FQs) are broad-spectrum antibiotics, with some recommended by WHO as second-line TB treatments for resistant or intolerant cases.

Purpose of the Study:

• To review recent advancements in the development of fluoroquinolone derivatives as anti-TB agents.
• To analyze the structure-activity relationships (SAR) of these novel FQ derivatives.
• To identify promising candidates for future anti-TB drug discovery.

Main Methods:

• Literature review of recent scientific publications.
• Synthesis and evaluation of novel fluoroquinolone derivatives.
• Structure-activity relationship analysis of synthesized compounds.

Main Results:

• Numerous fluoroquinolone derivatives have been synthesized and evaluated for anti-TB activity.
• Some derivatives have demonstrated promising potency against Mycobacterium tuberculosis.
• Key structural modifications influencing anti-TB activity have been identified.

Conclusions:

• Fluoroquinolone derivatives represent a promising avenue for developing new anti-TB drugs.
• Understanding SAR is crucial for optimizing the efficacy and safety of these agents.
• Further research is warranted to develop clinically viable fluoroquinolone-based anti-TB therapies.
