We synthesized the six presumed metabolites (2—7) of 4-(2-methyl-1H-imidazol-1-yl)-2,2-diphenylbutanamide [KRP-197/ONO-8025, 1], a urinary incontinence therapeutic agent, in order to confirm the structures of the metabolites. Metabolite (2) was synthesized via glucuronidaion of compound (1) and methyl 2,3,4-tri-O-benzoyl-1-methanesulfonyl-α-D-glucopyranuronate. Metabolite (3) was synthesized via 3-(tert-butoxycarbonyl)-2-methyl-1,3-imidazolidine-4,5-dione. Metabolites (4—7) were synthesized via 4-amino-2-diphenylbutanamide, respectively. The structures of the metabolites (2—7) in humans were identified by means of synthesis of the authentic compounds.
我们合成了4-(2-甲基-1H-咪唑-1-基)-2,2-二苯基丁酰胺[KRP-197/ONO-8025, 1]这一尿失禁治疗药物的六种假定代谢物(2—7),以确认这些代谢物的结构。代谢物(2)通过化合物(1)与甲基2,3,4-三-O-苯甲酰基-1-甲磺酰基-α-D-吡喃葡萄糖醛酸的葡萄糖醛酸化反应合成。代谢物(3)通过3-(叔丁氧羰基)-2-甲基-1,3-咪唑烷-4,5-二酮合成。代谢物(4—7)分别通过4-氨基-2-二苯基丁酰胺合成。通过合成标准化合物,确定了人体内代谢物(2—7)的结构。
