(2R)-3-[(2S,5R,6R,8S)-8-[(2R,3E)-4-[(2R,4'ar,5R,6's,8'r,8'as)-8'-hydroxy-6'-[(1S,3S)-1-hydroxy-3-[(2S,3R,6S)-3-methyl-1,7-dioxaspiro[5.5]undecan-2-yl]butyl]-7'-methylidene-hexahydro-3'h-spiro[oxolane-

Okadic acid is a toxin produced by some marine algae (dinoflagellates). It collects in mussels and causes a fish poisoning.

Characteristics

Okadic acid diol ester is soluble in fat, can thus pass through biomembranes and thus penetrate into cells of other organisms, where the ocadic acid diol ester is again hydrolyzed to the actual, toxicly acting ocadic acid
