摘要: Four brominated aliphatic hydrocarbons (1-4), including a novel brominated ene-tetrahydrofuran named as mutafuran H (1), and five sterols (5-9) were isolated from the South China Sea sponge Xestospongia testudinaria. The structure of 1 was determined on the basis of NMR (~1H, ~(13)C NMR, HSQC, HMBC, ~1H-~1H COSY, and NOESY), MS, and optical rotation analysis. Known compounds were identified by comparison of their NMR data with those reported in the literature. Compounds 1-4, and 6-9 were evaluated for their toxicity against Artemia salina larvae, and anti-acetylcholinesterase activity.
