目的 对海洋真菌Aspergillus sp. SCS-KFD03的发酵液中化学成分进行分离鉴定,并测定其生物活性。 方法 采用硅胶柱色谱、Sephadex LH-20凝胶柱色谱和高效液相色谱等技术进行分离纯化,运用各种波谱方法对分离所得化合物进行结构鉴定,并测定化合物乙酰胆碱酯酶和α-糖苷酶抑制活性。结果 分离鉴定了9个化合物,经鉴定为phomaligol A1(1)、5-(乙酰氧基甲基)呋喃-3-酸(2)、 phomapyrone C(3)、4-羟基异苯并呋喃-1(3H)-酮(4)、penicillivinacine(5)、22(E)-5α,8α-epidioxyergosta-6,22-dien-3β-ol(6)、lucidal(7)、dankasterone A(8)、bis-(2-methylheptyl)-phthalate(9),其中化合物4为新天然产物。化合物5、6、7和9具有较弱的乙酰胆碱酯酶抑制的活性,化合物5具有强于阳性药阿卡波糖的α-糖苷酶抑制活性,8和9的α-糖苷酶抑制活性与阳性药相当。结论 化合物1~9均为首次从海洋曲霉属真菌Aspergillus sp. SCS-KFD03中分离得到,部分化合物具有乙酰胆碱酯酶和α-糖苷酶的抑制活性。 |
English Summary: |
Objective To study the chemical constituents from the fermentation broth of marine-derived fungus Aspergillus sp. strain SCS-KFD03. Methods The constituents were isolated and purified by Silica gel, Sephadex LH-20 column chromatography and HPLC chromatography and identified by spectral data analyses, while their acetylcholinesterase and α-glucosidase inhibitory activities were evaluated. Results Nine compounds were isolated from the marine-derived fungus Aspergillus sp.SCS-KFD03 and identified as phomaligol A1 (1), 5- (acetoxymethyl) furan-3 acid (2), phomapyrone C (3), 4-hydroxyisobenzofuran-1(3H)-one (4), penicillivinacine (5), 22(E)-5α,8α-epidioxyergosta-6,22-dien-3β-ol (6), lucidal (7), dankasterone A (8), bis-(2-methylheptyl)-phthalate (9). Among the compounds, compound 4 is a new natural product. The acetylcholinesterase and α-glucosidase inhibitory activities of these compounds were evaluated at the first time. Compounds 5, 6, 7, and 9 showed weak inhibitory activities against acetylcholinesterase. Compound 5 has stronger inhibitory activity against α-glucosidase than the positive drug acarbose, while compounds 8 and 9 exhibited inhibitory activity against α-glucosidase as strong as the positive drug. Conclusion All the compounds were obtained from the Aspergillus sp. SCS-KFD03 for the first time, and some of them had a certain inhibitory activity on acetylcholinesterase and α-glucosidase. |
