DNA Adduct Formation from Metabolic 5′-Hydroxylation of the Tobacco-Specific Carcinogen N′-Nitrosonornicotine in Human Enzyme Systems and in Rats

N ′-Nitrosonornicotine (NNN) is carcinogenic in multiple animal models and has been evaluated as a human carcinogen. NNN can be metabolized by cytochrome P450s through two activation pathways: 2′-hydroxylation and 5′-hydroxylation. While most previous studies have focused on 2′-hydroxylation in targ...
