目的 探究Xest,ospongia testudinaria海绵共生真菌Penicillium janthinellum LZDX-32-1的次生代谢产物及其抗乙型肝炎病毒(HBV)活性。方法 对菌株进行发酵,运用现代色谱学方法(硅胶柱色谱、凝胶柱色谱、C-18反相柱色谱,以及半制备HPLC)对发酵产物进行分离,运用现代波谱学技术(核磁共振、质谱、紫外等),结合文献数据对比鉴定了化合物的结构;采用HepG2.2.15细胞模型的HBV DNA 水平用实时定量 PCR测定评价化合物的抗HBV活性。结果 分离鉴定了11个化合物,分别为:penialidin C (1)、penialidin A(2)、6-(2,4-dihydroxy-6-methylphenyl)-4-hydroxy-2-pyrone(3)、trans-3,4-dihydro-3,4,8-trihydroxynaphthalen-1(2H)-one(4)、epi-?isoshinanolone (5)、 pyrenocine B(6)、FK17-P2b1(7)、cordyol C(8)、diorcinol(9)、p-acetamidobenzoic acid(10)、2-(2-oxoindolin-3-yl)-acetamide(11)。 活性评价结果报道化合物5显示有抗HBV活性。结论 Xestospongia testudinaria海绵共生真菌 Penicillium janthinellum LZDX-32-1能够代谢产生具有抗HBV活性的次生代谢产物。 |
English Summary: |
Objective To investigate the bioactive secondary metabolites of Xestospongia testudinaria associated fungus Penicillium janthinellum LZDX-32-1. Methods After larger scaled fermentation, the secondary metabolites were isolated from the crude extracts of culture broth based on column chromatography over silica gel, Sephadex-LH 20, C-18 ODS and semi-prepared HPLC. Their structures were elucidated through spectroscopic analysis of UV, ESI-MS, 1D and 2D NMR, as well as by comparison with the data of literatures. The anti-HBV activities were assayed using HBV mRNA level testing with reverse-transcript PCR in Hep G2.2.15 cells, Results Eleven compounds were isolated and identified as penialidin C(1), penialidin A(2),6-(2,4-dihydroxy-6-methylphenyl)-4-hydroxy-2-pyrone(3),trans-3,4-dihydro-3,4,8-trihydroxynaphthalen-1(2H)-one(4), epi-?isoshinanolone(5), pyrenocine B(6), FK17-P2b1(7), cordyol C(8), diorcinol(9), p-acetamidobenzoic acid(10), 2-(2-oxoindolin-3-yl)-acetamide(11). In vitro bioassay showed that compound 5 exhibited anti-HBV activity. Conclusion The fermentation of strain LZDX-32-1 could produce secondary metabolites with anti-HBV antivity. |
