概要:北部湾藴育着丰富且亟待研究的海洋(微)生物资源,是活性天然产物的重要来源。本研究从涠洲岛珊瑚共附生构巢裸胞壳菌GXIMD 02509中分离获得一个多硫代二酮哌嗪生物碱和系列芳香聚酮类化合物,包含一个新化合物4a-O-methoxyarugosin H (1)。我们通过采用多种波、光谱学技术及对比文献方法鉴定了化合物的化学结构。化合物1~5、7和10对786-O、SW1990和SW480等3株肿瘤细胞增殖具抑制活性,半抑制浓度(IC50)值为4.3~33.4 μmol/L。化合物emestrin J (10)具有一个二硫桥键,还能够显著抑制786-O细胞克隆及迁移,诱导786-O细胞凋亡并阻滞细胞分裂在G2/M期,是一个潜在具抗肿瘤活性的先导化合物。
