摘要 目的研究中国南海蜂海绵属Haliclona cymaeformis的化学成分。方法运用正相硅胶、反相硅胶(ODS)和凝胶(Sephadex LH-20)等多种柱色谱手段对化合物进行分离纯化;通过理化性质和波谱数据,结合文献对照,鉴定化合物的结构。结果从海绵H.cymaeformis的乙醇提取物中共分离鉴定了11个单体化合物:24-亚甲基胆甾醇(1),5α,8β-epidioxy-cholesta-6-en-3-ol(2),cholesta-7-en-3β,5α,6β,9α-tetraol(3),胆甾醇(4),3-吲哚甲酸(5),尿嘧啶(6),胸腺嘧啶(7),尿嘧啶核苷(8),胸腺嘧啶核苷(9),尿嘧啶脱氧核苷(10)和胸腺嘧啶脱氧核苷(11)。结论化合物1~11均为首次从该海绵中分离得到。细胞毒活性测试结果表明,化合物3对慢性髓原白血病细胞(K562)和人肝癌细胞(SMMC-7721)的增殖显示了较强的生长抑制活性。 Objective To study the chemical constituents of the sponge Haliclona cymaeformis collected from the South China Sea.Methods The compounds were isolated and purified by column chromatography on silica gel,reversed-phase silica gel(ODS) and Sephadex LH-20,and their structures were elucidated on the basis of physicochemical and spectral analysis.Results Eleven compounds were isolated from the ethanol extract of H.cymaeformis,and their structures were identified as 24-methylene-cholesta-3β-ol(1),5α,8β-epidioxy-cholesta-6-en-3-ol(2),cholesta-7-en-3β,5α,6β,9α-tetraol(3),cholesterol(4),1H-indole-3-carboxylic acid(5),uracil(6),thymine(7),uridine(8),thymidine(9),2'-deoxyuridine(10),and 2'-deoxythymidine(11),respectively.Conclusion All the isolated compounds were obtained from the sponge H.cymaeformis for the first time.Compounds 3 showed significant inhibitory activities towards chronic myelogenous leukemia(K562) and human hepatoma(SMMC-7721) cell lines.
