Four new aaptamine alkaloids, named as 9-methoxy-N-demethylaaptanone (), 3,5-dicarbomethoxy-1,6-naphthyridine (), aaptosvanphongs A and B ( and ), and three known aaptamine alkaloids as 2-methoxy-3-oxoaaptamine (), 8,9,9-trimethoxy-9-benzo[][1,6]-naphthyridine (), and demethyl(oxy)aaptamine () were isolated from the sponge by various chromatographic methods. Their structures were established by extensive spectroscopic analyses (HR-ESI-MS, 1 D and 2 D NMR) and by comparison of the spectral data with those reported in the literature. Compounds - significantly showed cytotoxic effects against SK-LU-1, MCF-7, HepG2, and SK-Mel-2 cell lines with IC values in range from 7.7 ± 0.8 to 51.4 ± 1.8 µM. Among them, compound exhibited the most cytotoxic activity with corresponding IC values of 9.2 ± 1.0, 7.8 ± 0.6, 8.4 ± 0.8, and 7.7 ± 0.8 µM.[Formula: see text].
