Polycyclic aromatic hydrocarbons (PAHs) are ubiquitous environmental pollutants. Due to its structural similarity with the potent carcinogen dibenzo[a,l]pyrene (DB[a,l]P) and because of its environmental presence, dibenzo[c,mno]chrysene (naphtho[1,2-a]pyrene, N[1,2-a]P) is of considerable research interest. We therefore developed an efficient synthesis of N[1,2-a]P, and examined its in vitro metabolism
多环芳烃(PAHs)是普遍存在的环境污染物。由于其与强致癌物二苯并[a,l]((DB [a,l] P)的结构相似性,并且由于其存在环境,因此二苯并[c,mno]((萘并[1,2-a] ,、 N [1,2-a] P)具有相当大的研究兴趣。因此,我们开发了N [1,2-a] P的有效合成方法,并通过雄性Sprague Dawley大鼠肝脏S9组分检查了其体外代谢。评价了其在鼠伤寒沙门氏菌TA 100中的诱变活性和在小鼠胚胎成纤维细胞中形态细胞转化的能力。根据光谱分析,体外主要代谢产物被鉴定为峡湾区二氢二醇反式9,10-二羟基-9,10-二氢-N [1,2-a] P(N [1,2-a ] P-9,10-二氢二醇),K区二醇N [1,2-a] P-4,5-二氢二醇和N [1,2-a] P-7,8-二氢二醇,以及1-,3-和10-羟基-N [1,2-a] P;通过独立合成也证实了N [1,2-a] P-9
