最近从巴西Pachychalina属海绵中鉴定出新的环星胺H、I、K和L。它们与已知的环星胺a - g在仅1.5毫克的混合物中分离出来。为了获得进一步的生物学研究材料，合成了四种新的环星胺。由于质谱法在鉴定这些化合物中起着至关重要的作用，因此讨论了环星胺的系统分析。(c) Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2006)。
Very recently the new cyclostellettamines H, I, K and L were identified from a Brazilian sponge of the genus Pachychalina. They were isolated together with the known cyclostellettamines A-G in a mixture of only 1.5 mg. To obtain further material for biological investigations, the synthesis of the four new cyclostellettamines has been carried out. Since mass spectrometry plays an essential role in identifying these compounds a systematic analysis of the cyclostellettamines is discussed. ((c) Wiley-VCH Verlag GmbH & Co.
