N-Nitrosoanabasine or NAB is a potent carcinogen and biomarker of exposure to cigarette smoke. It′s found in a variety of tobacco products including chewing tobacco and snuff. Certified Spiking Solutions® are suitable for use in LC-MS/MS or GC/MS methods for nicotine testing, environmental monitoring, or clinical and diagnostic testing of nicotine biomarkers.

Exposure to tobacco-specific nitrosamines (TSNA) has been measured in the saliva of 12 users of Sudanese oral snuff (toombak). Using GC coupled to thermal energy analysis, levels of N'-nitrosonornicotine (NNN), N'-nitrosoanatabine (NAT), N'-nitrosoanabasine (NAB) and 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) were measured before
We compared the metabolism in the F-344 rat of the moderately potent esophageal carcinogen N'-nitrosonornicotine (NNN, 2'-(3-pyridyl)-N-nitrosopyrrolidine) and its weakly active homologue N'-nitrosoanabasine (NAB, 2'-(3-pyridyl)-N-nitrosopiperidine). Urine was the major pathway of excretion for both nitrosamines. The major urinary metabolites of

This research assessed the relationship between the deliveries of carcinogenic tobacco-specific nitrosamines (TSNAs) and the Federal Trade Commission (FTC) "tar" ratings of US commercial cigarettes. Analysis of covariance (ANCOVA) was used to assess the explanatory power of FTC tar, the

Tobacco-specific nitrosamines (TSNA) are among the most important and abundant strongly carcinogenic agents in unburned tobacco. It has been established that 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) induces lung tumors in rodents independent of the route of administration. N'-Nitrosonornicotine (NNN) causes tumors of the

Smokeless tobacco (ST) is known to adversely effect the oral mucosa, but knowledge about the influence on immune defence is limited. Few studies have investigated the effect of ST on the local immune response. In the present study, we have
