of the fungal metabolite isolated. The dicarboxylic acid inhibited autoxidation of Fe(2+) to Fe(3+) as well as reduction of Fe(3+) to Fe(2+) by the strong natural reductants, cysteine, glutathione, and ascorbic acid. The formation of charge transfer complexes (CTCs) between 1-heptadecene-2,3-dicarboxylic acid and oxidized intermediates from phenolic substrates were also observed. Thus, we herein report
1999年,我们首次报道了一种白腐真菌,Ceriporiopsis subvermispora产生了一系列新型的烷基衣康酸(ceriporic acid)。在本文中,我们通过格利雅(Grignard)反应合成了代谢物1-壬二茂-2,3-二羧酸(癸二酸B),以分析烷基衣康酸酯的化学性质。合成化合物的质谱仪(MS)和核磁共振谱(NMR)与分离出的真菌代谢物相同。二羧酸抑制Fe(2+)到Fe(3+)的自氧化以及通过强天然还原剂,半胱氨酸,谷胱甘肽和抗坏血酸还原Fe(3+)到Fe(2+)。还观察到1-庚二烯-2,3-二羧酸与酚醛底物的氧化中间体之间形成了电荷转移络合物(CTC)。从而,
