  • Phenolic acid sulfate esters for prevention of marine biofouling
    Patent number: 5607741
    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.
    Type: Grant
    Filed: December 8, 1994
    Date of Patent: March 4, 1997
    Assignees: ARCH Development Corporation, The Regents of the University of California
