A new aaptamine class alkaloid, designated 2-methoxy-3-oxoaaptamine (1), together with seven known aaptamines (2–8) were isolated from a marine sponge of Aaptos sp. as anti-mycobacterial substances against active and dormant bacilli. The chemical structure of 1 was determined on the basis of spectroscopic analysis. Com�pound 1 was anti-mycobacterial against Mycobacterium smegmatis in both active growing and dormancy-inducing hypoxic conditions with a minimum inhibitory concentra�tion (MIC) of 6.25 lg/ml, and compounds 2, 5, 6, and 7 showed anti-mycobacterial activities under hypoxic con�dition selectively, with MIC values of 1.5–6.25 lg/ml. Keywords Aaptamine � Marine sponge � Anti-mycobacterial activity � Dormant � Tuberculosis
