Leiopathic acid

Studies of the natural products of the antipatharian (Hexacorallia), Leiopathes sp., obtained during an expedition to the South Indian Ocean, led to the isolation of one novel oxylipin, (+)- 10P-hydroxydocosa-7Z, 11E, 13Z, 16Z, 19Z-pentaenoic acid (= leiopathic acid, 31), as well as two known compounds,... 

Guerriero, A., D Ambrosio, M., and Pietra, F. (1988b) Leiopathic acid, a novel optically active hydroxydocosapentaenoic acid, and related compounds, from the black coral Ldopathes sp., of Saint Paul Island. 

Three 20- and 22-carbon atom polyethylenic adds, bearing a hydroxyl group on carbon 8, were isolated from a black coral, a zoantharian of the genus Leiopathes whose spedes name is now Leiopathes glaberrima. These acids are probably derived from arachidonic acid and eicosapentae-noic acid (EPA), and fall into the category of oxylipins.
