The isolation is reported of four new variants of the halichondrin B skeleton, very minor potently bioactive components from the Poecilosclerid sponge Lissodendoryx sp. These compounds were isolated in microgram quantities only from a collection of 1tonne of sponge. The structural elucidations relied heavily on the use of capillary NMR spectroscopy and the application of an HSQC-DEPT overlay technique.
据报道，从苔藓海绵Lissodendoryx sp.中分离出了四种新的软海绵素B骨架变体，它们是非常微量但具有强效生物活性的成分。这些化合物仅从1吨海绵样品中以微克量分离得到。结构解析在很大程度上依赖于毛细管核磁共振光谱的使用以及HSQC-DEPT叠加技术的应用。
