Central nervous system activity of terpenoids from marine sponge

Some terpenoids extracted from marine sponge: triacetylated disidein, 2-tetraprenyl benzoquinol and 4 hydroxy-3-tetraprenylbenzoic acid 2-polyprenyl benzoquinols, avarol and furospongin-1 were tested by multidimensional Irwin screening and with some tests for analgesic and muscle relaxant activity. The three prenylhydroquinols derivatives and avarol show a good analgesic activity and low toxicity.
