Mycobacterium tuberculosis (MTB) requires a perpetual supply of iron for its sustenance. Iron scarcity and its limited availability in the host environment because of an encounter of various sites during the establishment of infection has led to the evolution of strategies for iron uptake, which includes biosynthesis of iron-chelating molecules called siderophores, Heme uptake pathways, recently discovered host iron transport protein receptors like glyceraldehyde-3-phosphate dehydrogenase and the development of machinery for proper storage of the acquired iron and its regulation. The components of the iron uptake machineries are viable targets in multidrug-resistant tuberculosis, some of which include the MmpL3 heme transfer protein, MbtA enzyme, and the ESX-3 system, while employment of approaches like the synthesis of siderophore drug conjugates, heme analogs, xenosiderophores as drug delivery agents, and the blockade of siderophore recycling are encouraged too. Thus, the mentioned discoveries stand as promising targets against various strains of MTB.
