代谢
(14)C-1,4-环己烷二甲醇(CHDM)(70% 反式异构体,30% 顺式异构体)溶于水,并通过灌胃的方式给予查尔斯河CD(SD)雄性和雌性大鼠,剂量为40或400 mg/kg体重。通过气相色谱和气相色谱-质谱法在血浆和尿液中鉴定代谢物。除了CHDM之外,在血浆中还检测到了4-羟甲基环己烷羧酸。尿液中原有的CHDM未被检测到。尿液中鉴定出的主要代谢物是环己烷二羧酸(68%)和4-羟甲基环己烷羧酸(31%)。尿液中不到2%的放射性物质未被完全鉴定。尿液中排出的代谢物的顺反比与原始剂量相同。
(14)C-1,4-cyclohexanedimethanol (CHDM) (70% trans-, 30% cis-isomers) was dissolved in water & given to male & female charles river cd (SD) rats by gavage in doses of 40 or 400 mg/kg of body wt. Metabolites were identified in plasma & urine by gas chromatography & gas chromatography-mass spectrometry. In addn to CHDM, 4-hydroxymethylcyclohexanecarboxylic acid was detected in plasma. Unchanged chdm was not detected in urine. The major metabolites identified in urine were cyclohexanedicarboxylic acid (68%) & 4-hydroxymethylcyclohexanecarboxylic acid (31%). Less than 2% of radioactivity in urine was not fully characterized. The cis-trans ratio of metabolites excreted in urine was the same as that of original dose.
