中文摘要: |
利用色谱法对一株海洋沉积物来源的放线菌 Streptomyces sp. AHMU XC 2026次级代谢
产物进行分离纯化,结合NMR波谱分析和文献比对鉴定10个单体化合物,分别为cyclo-( trans -4-
OH- D -Pro- D -Phe)(1 1),cyclo-( D -Pro- D -Phe)(2 2),cyclo-( L -Ala- L -Phe)(3 3),cyclo-( L -leucine- L -
proline)(4 4),cyclo-( L -Leu- trans -4-hydroxy- L -Pro)(5 5),cyclo-( D -Pro- D -Ile)(6 6), trans -2-methyl-
cinnamic acid(7 7),indole-3-carboxaldehyde(8 8),2-pyrrolecarboxylic acid(9 9),2-hydroxy phenyl acetic
acid(0 10)。采用滤纸片扩散法筛选抗植物病原真菌活性,结果表明化合物10 10在100 μg/disc下对水
稻稻瘟真菌 Pyricularia oryzae HNM 1003具有微弱的抑制活性,抑制圈直径为8 mm。 |
英文摘要: |
An investigation for the secondary metabolites from a marine sediment-derived Streptomyces sp. AHMU XC
2026was performed, leading to an attainment of ten known compounds by NMR spectroscopic analysis and comparisons of
literature data, including cyclo-(trans-4-OH- D -Pro- D -Phe) (1), cyclo-( D -Pro- D -Phe)(2), cyclo- ( L -Ala- L -Phe) (3), cy⁃
clo-( L -leucine- L -proline) (4), cyclo-( L -Leu-trans-4-hydroxy- L -Pro) (5), cyclo-( D -Pro- D -Ile) (6), trans-2-methylcin⁃
namic acid (7), indole-3-carboxaldehyde (8), 2-pyrrolecarboxylic acid (9), 2-hydroxy phenyl acetic acid (10). All the iso⁃
lated compounds were evaluated on antifungal activity against a panel of four plant pathogenic fungi by an agar diffusion
method, which indicated that the compound 10 showed a weak inhibitory activity for Pyricularia oryzae HNM 1003 with an
inhibition zone diameter of 8 mm under 100 mg/disc. |
