Abstract: Six new cyclic peroxides (16) were isolated from the Korean sponge Plakortis simplex, along with two new alkylpyridinium alkaloids (7 and 8). The structures of these compounds were completely determined by a combination of NMR analysis and chemical reactions. Compounds 16 exhibited cytotoxic/antifungal activities against RAW264.7 cells and Candida albicans.
Keywords: Plakortis simplex; cyclic peroxide; cyclic peroxyketal; pyridinium; NMR
