Three new aminolipopeptides, designated trichoderins A (1), A1 (2), and B (3), were isolated from a culture of marine sponge-derived fungus of Trichoderma sp. as anti-mycobacterial substances with activity against active and dormant bacilli. The chemical structures of trichoderins were determined on the basis of spectroscopic study. Trichoderins showed potent anti-mycobacterial activity against Mycobacterium smegmatis, Mycobacterium bovis BCG, and Mycobacterium tuberculosis H37Rv under standard aerobic growth conditions as well as dormancy-inducing hypoxic conditions, with MIC values in the range of 0.02-2.0 mu g/mL.
