Overview of Small Molecules as Fluorescent Probes of Mycobacterium tuberculosis .

Tuberculosis (TB) remains one of the leading infectious causes of death worldwide. Detecting and precisely quantifying viable Mycobacterium tuberculosis ( M. tuberculosis ) is crucial for comprehending mycobacterial pathogenicity; the progression and outcomes of tuberculosis; and the action, efficacy, and resistance of drugs. Fluorescent probes have emerged as indispensable tools for studying the intricate structure and dynamic interactions of M. tuberculosis with its host environment. This minireview underscores the significance of small molecules as fluorescent probes in advancing our understanding of mycobacterial biology and highlights their potential for guiding the development of novel therapeutic interventions against tuberculosis.
