The hydroxyl groups of dibenz[a,h]anthracene trans-1,2-dihydrodiol and chrysene trans-3,4-dihydrodiol are known to be predominantly in quasi-axial conformations. These dihydrodiols were metabolized by liver microsomes from 3-methylcholanthrene-pretreated rats to form 1,2,3,4-tetrahydrotetrols as the major products. The major metabolites of the dihydrodiols were isolated by reversed-phase high-performance liquid chromatography and identified by ultraviolet--visible absorption and mass spectral analyses. The results indicate that axial hydroxyl groups of dibenz[a,h]anthracene trans-1,2-dihydrodiol and of chrysene trans-3,4-dihydrodiol do not direct metabolism away from their respective vicinal double bond.
已知二苯并[a,h]蒽反式-1,2-二氢二醇和屈反式-3,4-二氢二醇的羟基主要处于准轴向构象。这些二氢二醇由经3-甲基胆蒽预处理大鼠的肝微粒体代谢,形成1,2,3,4-四氢四醇作为主要产物。通过反相高效液相色谱法分离二氢二醇的主要代谢产物,并通过紫外-可见吸收和质谱分析进行鉴定。结果表明,二苯并[a,h]蒽反式-1,2-二氢二醇和屈反式-3,4-二氢二醇的轴向羟基不会使代谢偏离其各自的邻位双键。
