Mycobactin biosynthesis in Mycobacterium tuberculosis facilitates iron acquisition, which is required for growth and virulence. The mycobactin biosynthesis inhibitor salicyl-AMS [5=-O-(N-salicylsulfamoyl)adenosine] inhibitsM. tuberculosis growth in vitro under iron-limited conditions. Here, we conducted a single-dose pharmacokinetic study and a monotherapy study of salicyl- AMS with mice. Intraperitoneal injection yielded much better pharmacokinetic parameter values than oral administration did. Monotherapy of salicyl-AMS at 5.6 or 16.7 mg/kg significantly inhibitedM. tuberculosis growth in the mouse lung, providing the first in vivo proof of concept for this novel antibacterial strategy.
