has role diterpenoid metabolite monohydroxybenzoic acid carbobicyclic compound organobromine compound callophycoic acid H 3-bromo-5-{[(1R,4aS,5R,6R,8aS)-6-bromo-5,8a-dimethyl-2-methylidene-5-(4-methyl-3-penten-1-yl)decahydro-1-naphthalenyl]methyl}-4-hydroxybenzoic acid 566.103 568.38100 A monohydroxybenzoic acid that is 3-bromo-4-hydroxybenzoic acid substituted at position 5 by a decahydronaphthalen-1-ylmethyl group which in turn is substituted by a bromo, two methyl groups, a methylidene and a 4-methylpent-3-en-1-yl group at positions 6, 5, 8a, 2 and 5 respectively. A diterpenoid isolated from the Fijian red alga Callophycus serratus, it exhibits antibacterial, antimalarial and anticancer activities.
