Abstract The material balance for the biotransformation of grindelic acid by Aspergillus niger was determined along with the isolation of two novel dimers identified as methyl-8α-hydroxy-grindelate-7β- O -7′β-ether hydrate and methyl-3β-acetoxy-8α-hydroxy-grindelate-7β- O -7′β-ether hydrate. Also identified were the known 19-hydroxy-grindelic acid and the novel 6α,17-dihydroxy-grindelic acid. All compounds
摘要 确定了黑曲霉生物转化甘地酸的物质平衡,并分离了两种新型二聚体,鉴定为甲基-8α-羟基-格林地酸-7β-O -7'β-醚水合物和甲基-3β-乙酰氧基- 8α-羟基-grindelate-7β-O -7'β-醚水合物。还确定了已知的 19-羟基-格林德酸和新的 6α,17-二羟基-格林德酸。所有化合物均以其乙酸甲酯衍生物的形式分离。已知的 3β-羟基-7α,8α-环氧格林德酸是将 3β-羟基-格林德酸用作生物转化底物时形成的唯一产物。
