New prenylated bromoquinols from the green alga Cymopolia barbata.
Six new prenylated bromohydroquinones, 3'-methoxy-7-hydroxycymopol (1), 3-hydroxycymopolone (2), 3,7-dihydroxycymopolone (3), 7-hydroxycymopochromanone (4), 7-hydroxycymopochromenol (5), and a related 6-hydroxy derivative of cymopochromenol (6), have been isolated from the green marine alga Cymopolia barbata. The structures of these cymopol-related metabolites were determined by spectral methods.
