摘要

摘要

En 中文
从海洋海绵Geodia microspinosa提取物中分离得到的一个组分,被鉴定为在针对抑制弥漫性胸膜间皮瘤(DPM)细胞系存活能力的分子高通量筛选中具有活性。生物活性引导的分离鉴定出microspinosamide B和D,以及一种新的人工产物microspinosamide C,同时还有两种先前报道的类似物microspinosamide和polydiscamide B作为活性成分。其平面结构通过NMR和HRESIMS分析解析,而高级Marfey反应、ROESY和ECD被用于确定其绝对构型。所有纯代谢物均显示出低微摩尔级活性,能够降低DPM细胞系的存活能力。
