Dysidea herbacea dysideathiazole from

The dysideathiazoles A-E (331-335) are a series of polychlorinated amino acid derivatives from Pacific Island collections of D. herbacea. The structures were determined by X-ray analyses and the absolute configurations were determined by X-ray crystallography of a brominated derivative [301]. Herbamide A (336), a chlorinated amide was isolated from a Papua New Guinean sample of D. herbacea as a minor component [302]. D. herbacea from the southern Great Barrier Reef contained a thiazole (337) amongst other known metabolites [303]. A Dysidea sp.
