Two previously unknown red alkaloid pigments, mycenarubin A (1), and a dimer thereof, mycenarubin B (6), have been isolated from fruiting bodies of Mycena rosea and the structures of these pyrroloquinoline alkaloids have been established by 2D NMR and ESI-MS methods. Their absoluteconfigurations were determined by comparison of their CD spectra with the CD spectrum of a synthetic model compound. The
两种先前未知的红色生物碱色素 mycenarubin A (1) 及其二聚体 mycenarubin B (6) 已从 Mycena rosea 的子实体中分离出来,这些吡咯并喹啉生物碱的结构已通过 2D NMR 和 ESI-MS 确定方法。它们的绝对构型是通过将它们的 CD 光谱与合成模型化合物的 CD 光谱进行比较来确定的。真菌色素在结构上与达米罗酮相关,从海绵中分离出来,可能是从色氨酸和 S-腺苷甲硫氨酸中生物合成衍生的。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2007)
