step toward identifying the spectrum of PAH o-quinone-amino acid adducts that may form in biological systems, several naphthalene-1,2-dione-amino acid adducts were synthesized. Each adduct was formed as a 1,4-Michael addition product and spectral data corroborate that these adducts were either o-quinones or catechols. PAH o-quinone adducts can be used as standards to identify their presence in vitro and
多环芳烃(PAH)是环境污染物,可能导致癌症并需要代谢激活才能发挥其致癌作用。作为确定可能在生物系统中形成的PAH邻醌-氨基酸加合物光谱的一步,合成了几种萘1,2-二酮-氨基酸加合物。每个加合物形成为1,4-迈克尔加成产物,并且光谱数据证实这些加合物是邻醌或邻苯二酚。PAH邻醌加合物可以用作标准品,以鉴定它们在体外和体内的存在。
