The sponge Oceanapia sagittaria from Palau contained the known sponge metabolite dercitamide (1) and a new pyridoacridine alkaloid sagitol (2). The structure of sagitol (2) was determined by interpretation of spectral data and confirmed by oxidation of dercitamide (1). CD measurements suggest that sagitol (2) is not an artifact.
