Seven new marine diterpenoids having a cembrane skeleton were isolatedfrom the Okinawan softcoralClavulariakoellikeri. Their structures were determined based on the results of spectroscopic analysis and chemical conversions. Compound 1 showed cytotoxic activity against human colorectal adenocarcinoma cells (DLD-1, IC(50) 4.2 g/mL) and strong growth inhibition against human T lymphocytic leukemia
从冲绳软珊瑚Clavularia koellikeri中分离出七种新的海洋生物二萜,它们具有薄膜骨架。根据光谱分析和化学转化的结果确定其结构。化合物1对人大肠腺癌细胞(DLD-1,IC(50)4.2 g / mL)表现出细胞毒活性,对人T淋巴细胞白血病细胞(MOLT-4,IC(50)0.9 g / mL)有很强的生长抑制作用。
