Tuberculosis is a leading cause of death worldwide. Resistance of Mycobacterium to antibiotics can make treatments less effective in some cases. We tested selected oligopeptoids--previously reported as mimics of natural host defense peptides--for activity against Mycobacterium tuberculosis and assessed their cytotoxicity. A tetrameric, alkylated, cationic peptoid (1-C13(4mer)) was most potent against M. tuberculosis and least cytotoxic, whereas an unalkylated analogue, peptoid 1(4mer), was inactive. Peptoid 1-C13(4mer) thus merits further study as a potential antituberculosis drug.
