New compounds, 6-hydroxytoluquinol-hydrate (3, 4) (VI), terremutin-hydrate (VII), and 4-chloro-3, 6-dihydroxytoluquinone (II) were isolated from Aspergillus terreus ATCC 12238 together with terreic acid, terremutin, 3, 6-dihydroxytoluquinone, and terrein. The metabolic relationships among the metabolites were studied by administration experiments using 14C-compounds and the metabolic scheme was proposed. The metabolic pattern of"epoxy compounds (terreic acid and terremutin)→quinone (3, 6-dihydroxytoluquinone) or its quinol→hydroaromatic compound (VI)"was essentially the same as observed in Aspergillus fumigatus DH 413 and IFO 4399.
新化合物 6-羟基甲苯醌水合物 (3, 4) (VI)、terremutin 水合物 (VII) 和 4-氯-3, 6-二羟基甲苯醌 (II) 与土酸、terremutin 一起从 Aspergillus terreus ATCC 12238 中分离出来、 3, 6-二羟基甲苯醌和土曲霉醇。通过14C化合物的给药实验研究了代谢物之间的代谢关系,并提出了代谢方案。 “环氧化合物(土酸和terremutin)→醌(3, 6-二羟基甲苯醌)或其对苯二酚→氢化芳香族化合物(VI)”的代谢模式与在烟曲霉DH 413和IFO 4399中观察到的基本相同。
