从日本深海海百合Hypalocrinus naresianus中分离得到5个新的水溶性氨基蒽醌类色素,即hypalocrininins A-E(1-5),新的氨基蒽醌类双芳基化合物hypalocrinin F(6)和hypalocrinin G(7),以及已知化合物6-溴大黄酸(8),crinemodin(9)和crinemodin sulfate(10)。化合物的结构经核磁共振谱和质谱确证。氨基醌和氨基醌在天然产物中是很不寻常的。低角青霉素是第一种天然存在的蒽醌和与牛磺酸缀合的蒽醌联芳化合物。
Five new water-soluble amido- and aminoanthraquinone pigments, hypalocrinins A–E (1–5), the new amidoanthraquinone biaryls hypalocrinin F (6) and hypalocrinin G (7), and the known compounds 6-bromoemodic acid (8), crinemodin (9), and crinemodin sulfate (10) were isolated from the deep sea crinoidHypalocrinus naresianuscollected off Japan. The structures of the compounds were elucidated by NMR spectroscopy and mass spectrometry. Amido- and aminoquinones are quite unusual among natural products. The hypalocrinins are the first naturally occurring anthraquinones and anthraquinone biaryls conjugated with taurine.
