Metabolites of guaiacol glycerol ether and its mononicotinate in rabbit urine were investigated. As the metabolites of guaiacol glycerol ether, β-(2-methoxyphenoxy) lactic acid, (2-methoxyphenoxy) acetic acid, β-(4-hydroxy-2-methoxyphenoxy) lactic acid, and (4-hydroxy-2-methoxyphenoxy) acetic acid (trace) were separated with unchanged GGE, and identified with the authentic samples by thin-layer chromatography. Two of the metabolites, β-(4-hydroxy-2-methoxyphenoxy) lactic acid and (4-hydroxy-2-methoxyphenoxy) acetic acid showed hypocholesteremic action on hypercholesteremia caused by intravenous injection of Triton to rats. As metabolites of guaiacol glycerol ether in rabbit liver and kidney in vitro, only β-(2-methoxyphenoxy) lactic acid was detected with the unchanged drug by thin-layer chromatography.
研究了兔尿中愈创木酚甘油醚及其单烟酸酯的代谢物。作为愈创木酚甘油醚、β-(2-甲氧基苯氧基)乳酸、(2-甲氧基苯氧基)乙酸、β-(4-羟基-2-甲氧基苯氧基)乳酸和(4-羟基-2-甲氧基苯氧基)的代谢物使用未改变的 GGE 分离乙酸(痕量),并通过薄层色谱法与真实样品进行鉴定。其中两种代谢物β-(4-羟基-2-甲氧基苯氧基)乳酸和(4-羟基-2-甲氧基苯氧基)乙酸对大鼠静脉注射Triton引起的高胆固醇血症显示出降胆固醇作用。作为愈创木酚甘油醚在兔肝脏和肾脏中的体外代谢物,通过薄层色谱法仅检测到原形药物的β-(2-甲氧基苯氧基)乳酸。
