Cymopolia barbata

Cymopolia barbata elaborates a unique series of (20 prenylated bromohydroqui-nones called the cymopols (Hoegberg et al. 1976). Monobromination is found exclusively para (directly across) to the site of prenylation as seen in cymopolone (Fig. 1.7f). The isoprene side chains all originate from C10 geranyl units with different...

New brominated monoterpenoids from Cymopolia barbata include cymopol [E-(249 X = H2)], the bromonium-ion-catalysed cyclization product, cyclocymopol (250), whose AT-ray structure has been determined, cymopolone and isocymopolone [E- and Z-(249 X = O) respectively], and cymopochromenol (251). ... 

About 15 meromonoterpenes - aU brominated - were isolated from two calcified species of the Caribbean Cymopolia barbata and Neomeris annulata. Cymobarbatol and 4-isocymobarbatol have antimutagenic properties (Gerwick, 1997).
