Four novel polyketide-derived metabolites, myriaporones 1, 2, 3, and 4, have been isolated from the Mediterranean bryozoan Myriapora truncata. Their structures and stereochemistry have been assigned from the analysis of spectroscopic data. The inseparable equilibrium mixture of myriaporones 3 and 4 showed 88% inhibition of L1210 murine leukemia cells at 0.2 microg/mL.
从地中海苔藓虫截形明孔苔虫(Myriapora truncata)中分离出了四种新的聚酮衍生代谢产物,即多孔苔虫素1、2、3和4。通过光谱数据分析确定了它们的结构和立体化学。多孔苔虫素3和4的不可分离平衡混合物在浓度为0.2微克/毫升时对L1210小鼠白血病细胞显示出88%的抑制率。
