对采自中国南海的软珊瑚Sinularia sp.的乙醇提取物进行了化学研究,分离出三种新的多氧甾醇,(3S,23 R,24 S)-麦角甾-5-烯-3 β,23 α,25-三醇(1),(24 S)-麦角甾烷-6-乙酸酯-3 β,5 α,6 β,25-四醇(2),(24 S)-麦角甾烷-6-乙酸酯-3 β,6 β,12 β,25-四醇(3)和三个已知的化合物(4-6)。新化合物(1-3)的结构和相对构型通过详细的光谱数据(IR,UV,NMR,MS)分析和与相关文献报道的化合物的比较而确定。用改进的Mosher方法进一步确定了1的绝对构型。化合物5对K562细胞株表现出中等的细胞毒性,IC 50值为3.18 μM,但对卤虫也表现出强烈的致死性,LC 50值为0.96 μM。
Chemical investigation of the ethanol extract of soft coral Sinularia sp. collected from the South China Sea led to the isolation of three new polyoxygenated sterols, (3S,23R,24S)-ergost-5-ene-3β,23α,25-triol (1), (24S)-ergostane-6-acetate-3β,5α,6β,25-tetraol (2), (24S)-ergostane-6-acetate-3β,6β,12β,25-tetraol (3) together with three known ones (4–6). The structures, including relative configurations of the new compounds (1–3), were elucidated by detailed analysis of spectroscopic data (IR, UV, NMR, MS) and by comparison with related reported compounds. The absolute configuration of 1 was further determined by modified Mosher’s method. Compound 5 exhibited moderate cytotoxicity against K562 cell line with an IC50 value of 3.18 μM, but also displayed strong lethality toward the brine shrimp Artemia salina with a LC50 value of 0.96 μM.
