Nontoxic Metal–Cyclam Complexes, a New Class of Compounds with Potency against Drug-Resistant Mycobacterium tuberculosis

Abstract
Tuberculosis (TB) accounted for 1.5 million deaths in 2014 and new classes of anti-TB drugs are required. We report a class of functionalized 1,8-disubstituted cyclam derivatives that display low micromolar activity against pathogenic mycobacteria. These compounds inhibit intracellular growth of Mycobacterium tuberculosis, are non-toxic to human cell lines and are active against multidrug-resistant M. tuberculosis strains, indicating a distinct mode of action. These compounds warrant further appraisal as novel agents to control TB in humans.
