Abstract

New therapeutics are urgently needed to fight tuberculosis and mycobacteria-related diseases that are a major health hazard especially in poor countries. Natural products have been the source of important antitubercular drugs in the past and still need to receive attention as a potent reservoir of chemical structures. Fifteen known and two new (+)-usnic acid (a benzofurandione formerly isolated from lichens) enamines and hydrazones are here described and tested against sensitive and multidrug-resistant strains of mycobacteria. Among several (+)-usnic acid conjugates, PS14 and PS18 showed potent activity against both susceptible and resistant Mycobacterium tuberculosis strains (MIC values of 1–32 and 2–32 mg/L, respectively) comparable with MIC of other antitubercular drugs already in use for tuberculosis treatment. © 2018 Deutsche Pharmazeutische Gesellschaft
