Abstract

A new sesquiterpene, 9-hydroxyfurodysinin-O-ethyl lactone, has been isolated from a New Caledonian Dysidea arenaria, along with three known compounds. The possible incorporation of the ethyl ether from the extraction solvent is discussed.

Highlights

Marine sponges belonging to the genus Dysidea generally contain sesquiterpenes [1], polychlorinated amino acids [2,3] or polybrominated diphenyl ethers [4,5], the latter two classes of compound have been shown to originate from the symbiotic cyanobacterium Oscillatoria spongeliae [6]
A freeze-dried sample of Dysidea arenaria from New Caledonia was extracted exhaustively with aqueous ethanol, and the combined extracts were partitioned against light petroleum and DCM
One new and three known compounds were isolated from a New Caledonian Dysidea arenaria

Summary

Introduction

Marine sponges belonging to the genus Dysidea generally contain sesquiterpenes [1], polychlorinated amino acids [2,3] or polybrominated diphenyl ethers [4,5], the latter two classes of compound have been shown to originate from the symbiotic cyanobacterium Oscillatoria spongeliae [6]. We describe the isolation, purification and structure elucidation of one new and three known compounds from a New Caledonian Dysidea arenaria
