treated with beta-glucuronidase and arylsulfatase. Seven metabolites, met B (2), met A-III (3), met E (4), met D (5), met F (6), met G (7), and met H (8) were isolated from the bile treated with the enzymes. Eight metabolites 2-8, and met A-II (9) were isolated from the urine treated with the enzymes. A major metabolite 2, and two minor metabolites 3 and 9 were identified as met B, met A-III, and met A-II
向大鼠口服戈米菌素A(1)后,收集胆汁和尿液,并用β-葡萄糖醛酸苷酶和芳基硫酸酯酶处理。从以下产品中分离出7种代谢物:B(2),A-III(3),E(4),D(5),F(6),G(7)和H(8)用酶处理的胆汁。从用酶处理过的尿液中分离出八种代谢物2-8和A-II(9)。主要代谢物2和两个次要代谢物3和9分别被鉴定为met B,met A-III和met A-II,它们是大鼠肝脏S9混合物形成的1的氧化产物。在化学和光谱研究的基础上确定了5种新的代谢物4-7和8的结构。
