p-Sulfooxyphenylpyruvic acid from the red macro alga Ceratodictyon spongiosum and its sponge symbiont Haliclona cymaeformis.
Investigation of a Philippine specimen of the red alga Ceratodictyon spongiosum and its sponge symbiont Haliclona cymaeformis led to the isolation of p-sulfooxyphenylpyruvic acid, whose structure was elucidated using spectroscopic methods, with the Z-enol geometry determined through analysis of (3)J(C,H) coupling constants. The metabolite was tested for tyrosine kinase inhibition using a (3)H-thymidine incorporation assay, but was found inactive.
