摘要:

为研究海风藤的化学成分及生物活性,本研究利用正、反相硅胶柱色谱、Sephadex LH-20及制备液相等色谱分离技术对海风藤茎中的化学成分进行分离纯化,并结合多种波谱技术鉴定出13个酰胺生物碱类化合物,分别为(2E,4E)-N-isobutyl-6-oxodeca-2,4-dienamide(1)、(4,5)-trans-N-isobutyl-4,5-epoxy-2E-decadienamide(2)、N-isobutyl-4-hexanoyl-4-hydroxypyrrolidin-1-one(3)、sylvamide(4)、N-isobutyl-2E,4E-octadienamid(5)、pellitorine(6)、N-isobuty-2E,4E-dodecadienamide(7)、N-isobutyl-2E,4E-octadecadienamide(8)、N-2′-methylbutyl-2E,4E-decadienamide(9)、N-isobutyl-2E,4E,12Z-octadecatrienamide(10)、N-isobutyl-2E-decenamide(11)、二氢荜茇明宁碱(12)、风藤酰胺(13)。化合物1为新化合物,化合物2为新天然产物,化合物3~7、9、10为首次从该植物中分离得到。采用MPP+致损伤的PC12细胞模型对分离得到的化合物1~10进行体外神经保活性测试,化合物6在20 μM时,对MPP+诱导的PC12细胞损伤具有显著的保护作用(P < 0.01)。

Abstract:

To study the chemical constituents and biological activities of Piper kadsura.The chemical constituents of the stems of Piper kadsura were purified by silica gel column chromatography,Sephadex LH-20 and preparative liquid chromatography.Based on various spectroscopic methods,13 amide alkaloids were identified as(2E,4E)-N-isobutyl-6-oxodeca-2,4-dienamide(1),(4,5)-trans-N-isobutyl-4,5-epoxy-2E-decadienamide(2),N-isobutyl-4-hexanoyl-4-hydroxypyrrolidin-1-one(3),sylvamide(4),N-isobutyl-2E,4E-octadienamid(5),pellitorine(6),N-isobuty-2E,4E-dodecadienamide(7),N-isobutyl-2E,4E-octadecadienamide(8),N-2′-methylbutyl-2E,4E-decadienamide(9),N-isobutyl-2E,4E,12Z-octadecatrienamide(10),N-isobutyl-2E-decenamide(11,dihydropiperlonguminimine (12) and futoamine (13).Compound 1 was a new compound,compound 2 was a new natural product,and compounds 3-7,9 and 10 were isolated from this plant for the first time.The neuroprotective activity of compounds 1-10 were tested in vitro by using MPP+ injured PC12 cell,compound 6 displayed a significant protective effect on MPP+ induced PC12 cell injury at 20 μM (P < 0.01).
