The echinoderms Asterias rubens and Marthasterias glacialis metabolize injected [4-(14)C]progesterone to give labelled 3beta-hydroxy-5alpha-pregnan-20-one and 3beta,6alpha-dihydroxy-5alpha-pregnan-20-one. These radioactive products are converted by the animals into conjugated forms that are soluble in aqueous methanol, and which have mobilities on t.l.c. similar to the asterosaponins.
海盘车(Asterias rubens)和多棘海盘车(Marthasterias glacialis)这两种棘皮动物将注射的[4-(14)C]孕酮代谢,生成标记的3β-羟基-5α-孕烷-20-酮和3β,6α-二羟基-5α-孕烷-20-酮。这些放射性产物被动物转化为可溶于甲醇水溶液的共轭形式,并且它们在薄层层析上的迁移率与海星皂苷相似。
