代谢
...二苯并[a,e]芘(DB[a,e]P)和二苯并[a,l]芘(DB[a,l]P)的NADPH支持的代谢在未经诱导和3-甲基胆蒽诱导的大鼠肝微粒体中进行。...经过诱导的微粒体代谢二苯并(a,e)芘的代谢物是二苯并(a,e)芘3,4-二氢二醇,3-羟基二苯并(a,e)芘,7-羟基二苯并(a,e)芘和9-羟基二苯并(a,e)芘。其中一些代谢物在评估癌症起始可能途径方面非常有用。
... The NADPH-supported metabolism of dibenzo[a,e]pyrene (DB[a,e]P) and dibenzo[a,l]pyrene (DB[a,l]P) was conducted with uninduced and 3-methylcholanthrene-induced rat liver microsomes. ... The metabolites of dibenzo(a,e)pyrene with induced microsomes were dibenzo(a,e)pyrene 3,4-dihydrodiol, 3-hydroxydibenzo(a,e)pyrene, 7-hydroxydibenzo(a,e)pyrene, and 9-hydroxydibenzo(a,e)pyrene. Some of these metabolites are very useful in assessing possible pathways of activation in the initiation of cancer.
