代谢
从口服beta-Myrcene后的大鼠尿液中分离出的代谢物包括:10-羟基沉香醇、7-甲基-3-亚甲基-辛-6-烯-1,2-二醇、1-羟基甲基-4-异丙烯基环己醇、10-羧基沉香醇和2-羟基-7-甲基-3-亚甲基-辛-6-烯酸。用苯巴比妥处理的大鼠肝脏微粒体在NADPH和氧气的存在下将beta-Myrcene转化为10-羟基沉香醇。NADH既不支持此反应,也没有显示出任何协同效应。从苯巴比妥处理的大鼠中制备的微粒体的转化速率显著高于从3-甲基胆蒽处理或对照微粒体制备的转化速率。10-羟基沉香醇的形成被美替拉酮、一氧化碳、SKF-525A、对氯汞苯甲酸盐(p-CMB)和细胞色素c所抑制...
Metabolites isolated from the urine of rats after oral administration of beta-myrcene were: 10-hydroxylinalool, 7-methyl-3-methylene-oct-6-ene-1,2-diol, 1-hydroxymethyl-4-isopropenyl cyclohexanol, 10-carboxylinalool and 2-hydroxy-7-methyl-3-methylene-oct-6-enoic acid. Liver microsomes prepared from phenobarbital-treated rats convert beta-myrcene to 10-hydroxylinalool in the presence of NADPH and oxygen. NADH neither supported this reaction nor did it show any synergistic effect. The rate of conversion was significantly greater in microsomes prepared from phenobarbital-treated rats than from 3-methylcholanthrene-treated or control microsomal preparations. The formation of 10-hydroxylinalool was inhibited by metyrapone, carbon monoxide, SKF-525A, p-chloromercuric benzoate (p-CMB) and cytochrome c. ...
