Cyclopheophorbide enol

Cyclopheophorbide enol (122) a nonmetalated chlorophyll a derivative was isolated from a New Zealand sponge (Darwinella oxeata) and its structure determined by X-ray measurements (113). Although 132,173-cyclopheophorbide enol (122) was first isolated from natural sources, it had previously been synthesized during a study of ring E enolization of chlorophyll derivatives (114). A new pheophorbide a-related compound named chlorophyllone a (123) was isolated from extracts of the short-necked clam Ruditapes philippinarum (115). Compound 123 exhibits antioxidative activity. [Pg.59]
