对拟诺卡氏菌YIM90087的固体发酵提取物进行了化学成分研究,从中分离得到10个化合物.通过波谱数据分析,鉴定其结构分别为:(3S)-3-苄基-2,5-哌嗪二酮(1)、(3S,6S)-3-(2-丁基)-6-(1-羟乙基)-2,5-哌嗪二酮(2)、(3S,6S)-3-(2-丁基)-6-羟甲基-2,5-哌嗪二酮(3)、(4S)-4-苄基-1,3-恶唑-2,5-二酮(4)、6'-羟基-4,2',3',4”-四甲氧基-对三联苯(5)、(3S,6S)-3-(4-羟苄基)-6-异丁基-2,5-哌嗪二酮(6)、(3R,8aS)-3-异丙基-六氢吡咯并[1,2-a]吡嗪-1,4-二酮(7)、(3S,6S)-3-异丁基-6-甲基-2,5-哌嗪二酮(8)、(3S,6S)-3-苄基-6-(1-羟乙基)-2,5-哌嗪二酮(9)和(3S,6S)-3-苄基-6-(1-羟丙基)-2,5-哌嗪二酮(10).化合物4目前只见化学合成报道,为新天然产物.
Study on Secondary Metabolites of Nocardiopsis sp.YIM 90087
The chemical constituents from the solid fermentation of Nocardiopsis sp.YIM90087 were studied.Ten compounds were isolated,and their structures were determined by spectral analysis as (3S)-3-benzylpiperazine-2,5-dione (1),(3S,6S)-3-(butan-2-yl)-6-(1-hydroxyethyl) piperazine-2,5-dione (2),(3S,6S)-3-(butan-2-yl)-6-(hydroxymethyl)piperazine-2,5-dione (3),(4S)-4-benzyl-1,3-oxazolidine-2,5-dione (4),6'-hydroxy-4,2',3',4"-tetramethoxyp-terphenyl (5),(3 S,6 S)-3-(4-hydroxybenzyl)-6-isobutylpiperazine-2,5-dione (6),(3 R,8 aS)-3-(propan-2-yl) hexahydropyrrolo [1,2-a] pyrazine-1,4-dione (7),(3S,6S)-3-isobutyl-6-methyl-piperazine-2,5-dione (8),(3S,6S)-3-benzyl-6-(1-hydroxyethyl) piperazine-2,5-dione (9),(3S,6S)-3-benzyl-6-(1-hydroxypropyl) piperazine-2,5-dione (10).Compound 4 was previously reported in chemical synthesis,and was a new natural product.
