Mycobacterial siderophore: A review on chemistry and biology of siderophore and its potential as a target for tuberculosis.
Patel K, Butala S, Khan T, Suvarna V, Sherje A, Dravyakar B.
Mycobacterium tuberculosis (MTB), the causative agent of tuberculosis is known to secrete low molecular mass compounds called siderophores especially under low iron conditions to chelate iron from host environment. Iron is essential for growth and other essential processes to sustain life of the bacterium in the host. Hence targeting siderophore is considered to be an alternative approach to prevent further virulence of bacterium into the host. This review article presents classification of siderophores, their role in transporting iron into the tubercular cell, biosynthesis of mycobactins, viability of siderophore as a therapeutic target and also focuses on overview on various approaches to target siderophore. The approaches encompass mutation effect on genes involved in siderophore recycling, synthetic as well as natural compounds that can inhibit further spread of bacterium by targeting siderophore.
