New Ceramides and Cerebrosides from the Deep-Sea Far Eastern Starfish Ceramaster patagonicus.

ABSTRACT: Three new ceramides (1-3) and three new cerebrosides (4, 8, and 9), along with three previously known cerebrosides (ophidiocerebrosides C (5), D (6), and CE-3-2 (7)), were isolated from a deep-sea starfish species, the orange cookie starfish Ceramaster patagonicus. The structures of 1-4,&nbsp;8, and 9 were determined by the NMR and ESIMS techniques and also through chemical transformations. Ceramides 1-3 contain iso-C₂₁ or C₂₃ Δ⁹-phytosphingosine as a long-chain base and have C₁₆ or C₁₇ (2R)-2-hydroxy-fatty acids of the normal type. Cerebroside 4 contains C₂₂ Δ⁹-sphingosine anteiso-<
