摘要: 本论文对一株绳生毛壳霉(Chaetomium funicola CIB-604)的次级代谢产物进行了研究。采用硅胶柱层析、Sephadex LH-20凝胶柱层析、半制备液相等色谱方法从其大米固体发酵物中分离得到了8个化合物,通过1H NMR、13C NMR和ESI-MS波谱数据分析将其分别鉴定为chaetoindicin A(1)、chaetoindicin B(2)、chaetoindicin C(3)、(22E,24R)-3β,5α,9α-trihydroxy-ergosta-7,22-dien-6-one(4)、(22E,24R)-5α,6α-epoxy-ergosta-8,22-dien-3β,7α-diol(5)、5α,6α-epoxy-(22E,24R)-ergosta-8(14),22-diene-3β,7α-diol(6)、麦角甾醇(7)和过氧麦角甾醇(8)。化合物1~8均首次从绳生毛壳霉中分离得到。活性研究表明,化合物1~6在100 μg/mL浓度下对大肠杆菌、枯草芽孢杆菌、白色念珠菌均没有明显抑制效果;化合物4对人肿瘤细胞株SK-Hep-1、A549、HCT-116和MCF-7均具有显著的细胞毒活性,而化合物2对这几株细胞具有中等强度的细胞毒活性。

Abstract:

The secondary metabolites of Chaetomium funicola CIB-604 were investigated in this paper.Eight compounds were isolated from the solid fermented rice culture by silica gel column chromatography,Sephadex LH-20 chromatography and semi-preparative liquid chromatography.On the basis of 1H NMR,13C NMR and ESI-MS spectroscopic data,their structures were identified as chaetoindicin A(1),chaetoindicin B(2),chaetoindicin C(3),(22E,24R)-3β,5α,9α-trihydroxy-ergosta-7,22-dien-6-one(4),(22E,24R)-5α,6α-epoxy-ergosta-8,22-dien-3β,7α-diol(5),5α,6α-epoxy-(22E,24R)-ergosta-8(14),22-diene-3β,7α-diol(6),ergosterol (7),and ergosterol peroxide (8).Compounds 1-8 were isolated from C. funicola for the first time. Compounds 1-6 showed no obvious inhibitory effect on Escherichia coli, Bacillus subtilis and Candida albicans at 100 μg/mL.Compound 4 exhibited significant cytotoxicities to SK-Hep-1,A549,HCT-116 and MCF-7 cells,while compound 2 showed moderate cytotoxicities against these cell lines.

Key words: Chaetomium funicola, alkaloid, sterol, antimicrobial activity, cytotoxicity
