代谢
3-羟基环己烷-1,2-甲酸酰胺(OHHPI-1/2)2和1-羟基-1,2-环己二酸(OHHPA)在非插管大鼠的尿液和粪便样本以及插管大鼠的胆汁和尿液样本中被检测到。1,2-环己二酸(TCDA)仅在口服3,4,5,6-四氢邻苯二甲酰亚胺(TPI)的非插管大鼠的尿液和粪便样本中被检测到。在给予3,4,5,6-四氢苯二甲酸(THPA)后,除了胆管插管大鼠静脉注射的粪便外,OHHPA在所有排泄物中被检测到。在非插管大鼠静脉注射THPA和口服THPA的胆管插管大鼠的所有排泄物中检测到TCDA。在给予TCDA的大鼠中没有检测到OHHPA。将从未经处理的雄性Sprague-Dawley大鼠获得的肝脏、胃、肠道组织及其内容物、肾脏、肺、脾和胰腺、血浆和血细胞样本与40纳米摩尔C14标记的TPI或THPA孵化1小时。像之前一样分析混合物以寻找代谢物。在TPI孵化后,从血细胞的上清液中检测到顺式-1,2-环己二酸亚胺。THPA和3,4,5,6-四氢邻苯二甲酸酐(TPA)在血浆和其他组织中被发现。在THPA孵化后,在肠道组织中检测到反式-TCDA,在肠道和肝脏中检测到OHHPA,在其他组织、血细胞和血浆中检测到TPA。
... 3-hydroxycyclohexane-1,2-carboximide (OHHPI-1/2)2 and and 1-hydroxy-1,2-cyclohexanedicarboxylic-acid (OHHPA) were detected in urine and feces samples from noncannulated rats and in bile and urine samples from cannulated rats. 1,2-cyclohexanedicarboxylic-acid (TCDA) was detected only in urine and feces samples from noncannulated rats administered 3,4,5,6-tetrahydrophthalimide (TPI) orally. Following 3,4,5,6-tetrahydrophthalic-acid (THPA) administration, OHHPA was detected in all excreta except in feces from bile duct cannulated rats injected intravenously. TCDA was detected in feces samples from noncannulated rats administered THPA intravenously and in all excreta from bile duct cannulated rats administered THPA orally. No OHHPA was detected in rats administered TCDA. Liver, stomach, intestinal tissues plus contents, and kidneys, lung, spleen, and pancreas, plasma and blood cell samples obtained from untreated male Sprague-Dawley-rats were incubated with 40 nanomoles C14 labeled TPI or THPA for 1 hour. The mixtures were analyzed for metabolites as before. cis-1,2-Cyclohexanedicarboximide was detected in supernatants from blood cells following incubation with TPI. THPA and 3,4,5,6-tetrahydrophthalic-anhydride (TPA) were detected in the plasma and other tissues. Following incubation with THPA, trans-TCDA was detected in the intestinal tissues, OHHPA was detected in the intestine and liver, and TPA was detected in the other tissues, blood cells, and plasma.
