Six new sesquiterpenoids, paralemnolins J-O (1-6), along with one novel norsesquiterpenoid, paralemnolin P (7), have been isolated from the soft coral Paralemnalia thyrsoides. The structures of metabolites 1-7 were established on the basis of extensive NMR study and chemical methods. The structure of 5 was further confirmed by a single-crystal X-ray analysis. Cytotoxicity of these metabolites toward a limited panel of cancer cell lines also is described.
从软珊瑚Thyrsoides Paralemnalia中分离出了6种新的倍半萜类化合物，paralemnolins J - O（1 - 6），以及一种新的降倍半萜类化合物，paralemolin P（7）。基于广泛的核磁共振研究和化学方法确定了代谢产物1 - 7的结构。通过单晶X射线分析进一步证实了化合物5的结构。还描述了这些代谢产物对一组有限的癌细胞系的细胞毒性。
