... 2-乙酰氨基芴的代谢及活化形成共价结合并具有致突变性的中间产物 ... 已在大鼠肝细胞悬浮液中进行了研究:细胞系可预测地产生了氧化、脱乙酰化和结合的代谢物。用β-萘黄酮预处理动物增加了酚类、结合和共价结合蛋白产物的含量。同样,添加4-硝基酚...增加了游离酚类的浓度并减少了结合:同时,共价蛋白结合的速率降低了。形成环状羟基化9-羟基-2-AAF被证实。...。
... Metabolism of 2-acetylaminofluorene & activation to covalently bound and mutagenic intermediates ... /has been studied in/ rat-hepatocyte suspensions: the cell system predictably afforded oxidized, deacetylated, and conjugated metabolites. Pre treatment of animals with beta-naphthoflavone increased the phenolic, conjugated and covalently bound protein products. Similarly, the addition of 4-nitrophenol ... increased concn of free phenols and decr conjugation: at same time rates of covalent protein binding were diminished. Formation of alicyclic hydroxylated 9-hydroxy-2-aaf was demonstrated. ... .
