"

05/01/2008 - "4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) is an important tobacco-specific nitrosamine (TSNA) in the etiology of tobacco-related cancers, and N-glucuronidation is an important mechanism of NNAL detoxification. "
11/25/2019 - "The adduct levels were measured in both tumor and adjacent normal tissues from 30 patients with lung cancer, including 13 current smokers and 17 current non-smokers, as confirmed by measurements of urinary cotinine and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol. "
10/08/2021 - "Our goal was to establish a robust method for simultaneous analysis of urinary total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), N'-nitrosonornicotine (NNN), and cotinine at the Advanced Centre for Treatment, Research and Education in Cancer (ACTREC) in Mumbai, India. "

01/01/2021 - "In this study, we used LC-MS/MS to measure the archetypical tobacco-specific carcinogenic 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK), its major metabolite, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), three biomarkers of oxidative stress (8-oxo-7,8-dihydroguanine, 8-oxoGua; 8-oxo-7,8-dihydro-2'-deoxyguanosine, 8-oxodGuo; 8-oxo-7,8-dihydroguanosine, 8-oxoGuo) and two biomarkers of alkylating stress (N7-methylguanine, N7-MeGua and N3-methyladenine, N3-MeAde), in the urine of smoking and non-smoking COPD patients and healthy controls. "

07/01/2014 - "It was found that target tissues of NNK carcinogenesis in C57BL/6 mice contained high levels of α-hydroxylation metabolites of NNK and its carbonyl reduction metabolite, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL). "
12/01/1995 - "We observed that lung, liver, and nasal mucosa, target tissues of NNK carcinogenesis in F344 rats, were also the tissues that had the highest levels of alpha-hydroxylation metabolites relative to NNK and its carbonyl reduction metabolite, 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL). "
01/01/2018 - "4-(Methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) are carcinogenic in animal models and are believed to play an important role in human lung carcinogenesis for cigarette smokers. "
01/01/2018 - "There is strong evidence that the tobacco-specific nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) and its metabolite 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL) play an important role in carcinogenesis caused by tobacco products. "

"
05/15/2014 - "We also demonstrated that urinary total 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol (NNAL), a biomarker of exposure to the lung carcinogen NNK, is strongly associated with the risk of lung, but not esophageal cancer in smokers. "
