Oxytoxin-2, An Algal-Derived Molecule from a Cultured Mollusc Volvatella vigourouxi
Abstract:
A natural caulerpenyne-derived sesquiterpene, oxytoxin-2 (1), was isolated from a cultured mollusc Volvatella vigourouxi. The structure of 1 was elucidated on the basis of spectroscopic analysis and this compound was suggested to be a diet-derived metabolite from the green alga Caulerpa sertularioides.-This is the first study on the chemical constituents of V. vigourouxi. Oxytoxin-2 (1) was found to inhibit significantly the expression of the pro-inflammatory inducible nitric oxide synthase (iNOS) protein of lipopolysaccharide (LPS)-stimulated RAW264.7 macrophage cells.
