K. Varvas et al., ENDOPEROXIDE PATHWAY IN PROSTAGLANDIN BIOSYNTHESIS IN THE SOFT CORAL GERSEMIA-FRUTICOSA, Tetrahedron letters, 35(44), 1994, pp. 8267-8270
An acetone powder preparation of the White Sea soft coral Gersemia Fru
ticosa converts exogenous arachidonic acid to a prostaglandin-endopero
xide, identified as PGG(2) by chemical and spectral studies. The latte
r serves as a key intermediate from which, evidently by nonenzymic tra
nsformations, all optically active coral prostaglandins are formed.
