Bioassay-guided fractionation of the fungus Eurotium repens resulted in the isolation of two new benzyl derivatives, (E)-2-(hept-1-enyl)-3-(hydroxymethyl)-5-(3-methylbut-2-enyl)benzene-1,4-diol (1) and (E)-4-(hept-1-enyl)-7-(3-methylbut-2-enyl)-2,3-dihydrobenzofuran-2,5-diol (2), along with seven known compounds (3-9) including five benzaldehyde compounds, flavoglaucin (3), tetrahydroauroglaucin (4), dihydroauroglaucin (5), auroglaucin (6), and 2-(2',3-epoxy-1',3'- heptadienyl)-6-hydroxy-5-(3-methyl-2-butenyl)benzaldehyde (7), one diketopiperazine alkaloid, echinulin (8), and 5,7-dihydroxy-4-methylphthalide (9). The chemical structures of these compounds were established on the basis of extensive 1D and 2D NMR and HRMS data. Compounds 1-4 and 6 showed good binding affinity for human opioid or cannabinoid receptors. These findings have important implications for psychoactive studies with this class of compounds.
真菌扩展青霉的生物活性导向分离得到两个新的苄基衍生物,(E)-2-(庚-1-烯基)-3-(羟甲基)-5-(3-甲基-2-丁烯基)-1,4-苯二酚(1)和(E)-4-(庚-1-烯基)-7-(3-甲基-2-丁烯基)-2,3-二氢苯并呋喃-2,5-二醇(2),以及七个已知化合物(3-9),包括五个苯甲醛化合物,黄曲霉素(3)、四氢金雀花碱(4)、二氢金雀花碱(5)、金雀花碱(6)和 2-(2',3'-环氧-1',3'-庚二烯基)-6-羟基-5-(3-甲基-2-丁烯基)苯甲醛(7),一个二酮哌嗪生物碱,埃奎林(8)和 5,7-二羟基-4-甲基邻苯二甲酸酐(9)。这些化合物的化学结构是基于广泛的 1D 和 2D NMR 和 HRMS 数据确定的。化合物 1-4 和 6 对人阿片类或大麻素受体表现出良好的结合亲和力。这些发现对这类化合物的精神活性研究具有重要意义。
