Sulfur Compounds and N-Alkyl Pyrroles in Tobacco Smoke

Hazardous Compounds in Tobacco Smoke

Tobacco smoke is a toxic and carcinogenic mixture of more than 5,000 chemicals. The present article provides a list of 98 hazardous smoke components, based on an extensive literature search for known smoke components and their human health inhalation risks. An electronic database of smoke components containing more than 2,200 entries was generated. Emission levels in mainstream smoke have been ...

Decarboxylative formation of N-alkyl pyrroles from 4-hydroxyproline.

N-Alkyl pyrroles are obtained in a single step from 4-hydroxyproline and aldehydes in just 15 min under microwave irradiation.

Association between tobacco smoke and serum nitric oxide metabolites concentration

Introduction: Cigarette smoking affects nitric oxide production. The aim of this study was to determine associations between tobacco smoke and serum nitric oxide metabolites (NOx) concentration. Methods: Serum NOx concentration was measured by the Griess method in 230 nonsmokers, 238 active, 196 passive and 29 waterpipe smokers. Subjects were selected from participants of Tehran Lipid and Gl...

Biological activity of tobacco smoke and tobacco smoke-related chemicals.

Exposure to whole cigarette smoke from reference cigarettes results in the prompt (peak activity is 6 hrs), but fairly weak (similar to 2 fold), induction of murine pulmonary microsomal monooxygenase activity. This activity can be detected by using as substrates either benzo(a)pyrene or ethoxyresorufin, and can be inhibited by treatment with cycloheximide or actinomycin D. Unlike the induction ...
