four new prostaglandins, (5E)-PGB2 (10), (5E)-13,14-dihydro-PGB2 (11), 13,14-dihydro-PGB2 (12) and 13,14-dihydro-PGB2-Me (13), together with ten known compounds were isolated from the soft coral Lobophytum sarcophytoides. The structures of these new secondary metabolites were identified by high resolution mass spectrometry (HR-ESIMS), nuclear magnetic resonance (NMR) and electron circular dichroism
两个新的西门烷型二萜类化合物,叶绿素A(1)和B(3),以及四个新的前列腺素(5E)-PGB2(10),(5E)-13,14-dihydro-PGB2(11),13,14从柔软的珊瑚叶蝉植物中分离出十个已知的化合物,包括-dihydro-PGB2(12)和13,14-dihydro-PGB2-Me(13)。这些新的次生代谢产物的结构通过高分辨率质谱(HR-ESIMS),核磁共振(NMR)和电子圆二色性(ECD)分析以及改进的Mosher方法进行鉴定。化合物6、7、9、10、12、13、15和16通过抑制脂多糖激活的RAW264.7细胞中一氧化氮(NO)的产生,显示出潜在的抗炎活性,IC50值为7.1至32.1μM,优于阳性对照消炎痛,IC50 = 39.8μM。
