Symbiospirols: novel long carbon-chain compounds isolated from symbiotic marine dinoflagellate Symbiodinium sp.
Symbiospirols A, B, and C, long carbon-chain compounds with a molecular weight of 1207 were isolated from the cultured symbiotic dinoflagellate Symbiodinium sp. Their planar structures and partial relative stereochemistries were elucidated based on 1D and 2D NMR spectra and a degradation reaction. Symbiospirols consisted of a C67-linear chain with a beta,beta'-dihydroxyl ketone moiety, eight hydroxyl groups, one tetrahydropyran ring, and two 1,6-dioxaspiro[4,4]nonane rings. Symbiospirol A had an inhibitory effect against l-phosphatidylserine-induced PKC activation.
