Abstract
  • This work is concerned with determining whether nicotine has a role in promoting oxidative damage in human tissue, particularly in lung tissue. This follows from recent reports of a novel lung disease found in some E-cigarette users, characterized by oxidative damage and elevated levels of neutrophils (termed “vaping disease”). It is thought that taurine has a protective function against oxidative and chlorinating damage by neutrophil generated hypochlorous acid (HOCl) through the formation of taurine chloramine, a less reactive species. Due to the high concentration of taurine in the lungs, it has been hypothesized that taurine chloramine acts as a “reservoir” for chlorinating potential, as to protect tissue. Our exploratory results have shown that nicotine, a molecule containing a tertiary amino group, is able to catalyze chlorinating reactions of taurine chloramine through the formation of a reactive intermediate, which we suspect to be the nicotine chlorammonium ion. This intermediate exhibits a rapid decline in oxidizing capacity over time, suggesting it degrades autocatalytically after formation. Additionally, we have experimentally demonstrated that this intermediate is able to kill E. coli at physiologically relevant nicotine concentrations. These preliminary results suggest that nicotine may have the ability to catalyze reactions that ultimately cause oxidative damage. Key Words: nicotine, chloramine, chlorammonium ion, taurine, oxidative damage
