callophycoic acid G

CHEBI:65563 ·resolve ·ANTIBACTERIAL ·EXACT SEEDED

A monohydroxybenzoic acid that is 4-hydroxybenzoic acid substituted at position 3 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. — ChEBI
