ADMET

代谢
当向带有插管胆管的大鼠施用柑橘红2号时,在胆汁中检测到了6种红色、水溶性的代谢物,并且在尿液中存在1-氨基-2-萘酚葡萄糖苷酸和1-氨基-2-萘酚硫酸盐的微量。
When citrus red number 2 was administered to rats with cannulated bile ducts, 6 red-colored, water-soluble metabolites were detected in bile, and traces of 1-amino-2-naphthol glucuronide and 1-amino-2-naphthol sulfate were present in urine.

代谢
1-氨基-2-萘基葡萄糖苷酸是人体内柑橘红2号的代谢物。
1-Amino-2-naphthyl glucuronide is a metabolite of citrus red number 2 in humans.
来源:Hazardous Substances Data Bank (HSDB)
代谢
正常大鼠服用色素后的尿液中含有6种代谢物:两种红色代谢物中的一种是柑橘红2号O-葡萄糖苷酸(2,5-二甲氧基苯基偶氮-2-萘基葡萄糖苷酸);两种产品未鉴定;另外两种是1-氨基-2-萘酚葡萄糖苷酸和1-氨基-2-萘酚硫酸盐。服用色素的狗的尿液中含有12种代谢物,其中1-氨基-2-萘酚硫酸盐的含量较高;然而,1-氨基-2-萘基葡萄糖苷酸未被检测到。
The urine of normal rats dosed with the color contained 6 metabolites: 1 of the two red-colored metabolites was the O-glucuronide of citrus red number 2 (2,5-dimethoxyphenylazo-2-naphthyl glucuronide); two of the products were unidentified; two others were 1-amino-2-naphthol glucoronide and 1-amino-2-napthol sulfate. The urine of dogs given color contained 12 metabolites, one of which, 1-amino-2-naphthol sulfate, was present in high concentrations; however, 1-amino-2-napthyl glucoronide was not detected.

代谢
在大鼠、兔和狗的肠内容物中体外孵化颜色的乳液,结果发现颜色被细菌群落破坏。
In vitro incubation of emulsions of the color with the intestinal contents of the rat, rabbit and dog resulted in destruction of the color by the bacterial flora.
来源:Hazardous Substances Data Bank (HSDB)
代谢
在大鼠尿液中发现了少量1-氨基-2-萘磺酸。这说明在动物体内,颜色在偶氮键处被还原,随后发生共轭作用,生成1-氨基-2-萘酚的O-葡糖苷酸和醚磺酸衍生物。
Small amounts of 1-amino-2-naphthyl sulphate were identified in the urine of rats. This demonstrates that the color is reduced at the azo linkage in the animal body followed by conjugation to give the o-glucuronide and ethereal sulphate derivatives of 1-amino-2-naphthol.

吸收、分配和排泄
在大鼠单次口服2-20毫克溶于玉米油中的剂量后,48小时内,粪便中回收了5到7%的给药色素。当剂量降至0.5毫克时,未发现色素。当以0.5%的干混合物给药时,粪便中发现了26.3%。兔子和狗显示了类似的结果。
After single oral doses of 2-20 mg in corn oil solution to rats, five to seven percent of the administered color was recovered in the feces in 48 hr. When the dose was reduced to 0.5 mg no color was found. When administered as a 0.5 percent dry mixture, 26.3 percent was found in the feces. Rabbits and dogs showed similar results.

吸收、分配和排泄
单次给药后,在体内脂肪中发现了少量色素。重复给药导致脂肪中色素浓度逐渐降低,最终在七到十天内完全消失。
After a single dose small amounts of the color were found in the body fat. Repeated administration resulted in gradual reduction of the concentration of the color in the fat and finally it disappeared altogether after seven to 10 days.
