Five unusual hexose derivatives were isolated from the carbohydrate portion of the solid-state fermentation extract of Actinosynnema pretiosum ssp. auranticum ATCC 31565, which is a producing strain of maytansinoids that are a family of 19-membered macrocyclic lactams having extraordinary cytotoxic and antineoplastic activities. Their structures were determined to be 2-deoxy-α-D-arabino-hexopyranose (1), 2-deoxy-β-D-arabino-hexopyranose (2), 3,6-anhydro-2-deoxy-α-D-arabino-hexcofuranose (3), 3,6-anhydro-2-deoxy-β-D-arabino-hexofuranose (4), and 2-(D-glycerol-1,2-dihydroxyethyl)furan (5) by NMR spectroscopic experiments.
从 Actinosynnema pretiosum ssp 固态发酵提取物的碳水化合物部分中分离出五种不寻常的己糖衍生物。 auranticum ATCC 31565,是一种美登木素生物碱生产菌株,美登木素生物碱是 19 元大环内酰胺家族,具有非凡的细胞毒性和抗肿瘤活性。它们的结构被确定为2-脱氧-α-D-阿拉伯-吡喃己糖(1)、2-脱氧-β-D-阿拉伯-吡喃己糖(2)、3,6-脱水-2-脱氧-α-D-通过 NMR 光谱实验分析阿拉伯呋喃己糖 (3)、3,6-脱水-2-脱氧-β-D-阿拉伯呋喃己糖 (4) 和 2-(D-甘油-1,2-二羟乙基)呋喃 (5) 。
