Anodic oxidation of 7,12-dimethylbenz[a]anthracene (7,12-DMBA) in the presence of dG yields four adducts and one oxygenated derivative of 7,12-DMBA: 7-methylbenz[a]anthracene (MBA)-12-CH 2 -C8dG (13%), 7-MBA-12-CH 2 -N7Gua (55%), 12-MBA-7-CH 2 -N7Gua (12%), 7-MBA-12-CH 2 -C8Gua (10%), and 7,12-(CH 2 OH) 2 -BA (10%). The first three are primary products of the electrochemical reaction, whereas the last
在 dG 存在下,7,12-二甲基苯并 [a] 蒽 (7,12-DMBA) 的阳极氧化产生四种加合物和一种 7,12-DMBA 的氧化衍生物:7-甲基苯并 [a] 蒽 (MBA)-12 -CH 2 -C8dG (13%), 7-MBA-12-CH 2 -N7Gua (55%), 12-MBA-7-CH 2 -N7Gua (12%), 7-MBA-12-CH 2 -C8Gua (10%) 和 7,12-(CH 2 OH) 2 -BA (10%)。前三个是电化学反应的初级产物,而后两个是次级产物
