Six new polyacetylenic alcohols, termed strongylotriols A and B; pellynols J, K, and L; and isopellynol A, together with three known polyacetylenic alcohols, pellynols A, B, and C were isolated from the marine sponges Petrosia sp., and Halichondria sp. collected in Okinawa, Japan. Their planer structures were determined based on 2D-NMR and mass spectrometric analysis of the degraded products by RuCl3
六种新的聚炔醇,分别称为强环糊精A和B;pellynols J,K和L;从海洋海绵Petrosia sp。和Halichondria sp。中分离了异炔醇A和异炔醇A,以及三种已知的聚炔醇A,B和C。在日本冲绳收集。基于2D-NMR和RuCl3氧化降解产物的质谱分析,确定了它们的平面结构。分离物的绝对立体化学通过其莫氏酯进行了检验。发现强吡咯醇是旋光纯的化合物,而pellynols是在C-6位的非对映异构体混合物。使用HeLa和K562细胞系进行的增殖实验表明,活性的基本结构单元是“ hexa-2,4-diyn-1,6-diol”和“ pent-1-en-4-yn-3-ol”在终点上。
