Abstract
p-sulfoxy cinnamic acid isolated from methanolic extracts of the eelgrass Zostera marina having significant antifouling aquatic properties. p-sulfoxy cinnamic acid was synthesized in the laboratory from p-coumaric acid, and antifouling activity was identical to the natural compound in laboratory bioassays. In addition, sulfate esters of other phenolic acids showed similar antifouling activity, suggesting that the sulfate ester was responsible for the antifouling effect.
