摘要: 利用硅胶柱色谱、Sephadex LH-20、ODS柱色谱和HPLC等手段对南海软海绵Halichondria sp.化学成分进行分离纯化,从中分离得到了7个化合物。通过通过理化性质、波谱分析方法结合文献对照,鉴定了化合物的结构分别为:4α-Isocyanogorgon-11-Ene(1),homoverrucosanol(2),neoverrucosanol(3),5α,6α-环氧-(22E)-麦角甾8,14,22-三烯-3β,7α-二醇(4), 5α,8α-过氧-(22E,24R)-麦角甾-6,22-二烯-3β-醇(5), ( 22E,24R)-麦角甾-7,22 -二烯-3β,5α, 6α,9α-四醇(6),3β,5α,9α,14β-四羟基-(22E)-麦角甾-7,22-二烯-6-酮(7)。以上7个化合物都是首次从该属海绵中分离得到。对7个化合物进行了体外毒性实验,化合物1和3对HeLa肿瘤细胞株显示较弱的细胞毒性,其IC50值为33.7 μM 和43.8 μM.

Abstract: The isolation and purification of the compounds were performed by silica gel,Sephadex LH-20,ODS and HPLC methods,and their structures were determined by comparing their physicochemical characters and spectral data with literatures.Seven compounds were isolated from the extracts of Halichondria sp.and inden tified as 4α-Isocyanogorgon-11-Ene(1),Homoverrucosanol(2),neoverrucosanol(3),5α,6α-Epoxy-(22E)-ergosta-8,14,22-triene-3β,7α-diol(4),5α,8α-epidioxy-(22E, 24R)-ergosta-6,22-dien-3β-ol(5), (22E, 24R)-ergosta-7,22-diene-3β,5α, 6α,9α-tetrol(6),3β,5α,9α,14β-tetrahydroxy-(22E)-ergosta-7,22-dien-6-one(7).All the compounds were isolated from Halichondria sp. for the first time,and compound 1 and 3 exhibited weak cytotoxicity against the HeLa cell line.The IC50 of them is 33.7 μM and 43.8 μM respectively.
