Nitrosamines and Derivatives

Applications 4-Methylmorpholine is used in the synthesis of novel and selective TYK2 inhibitors, used in the treatment of inflammatory diseases. Also used in the preparation of cathespin K inhibitors which are highly selective.

Applications N'-Nitrosonornicotine (NNN) is a tobacco alkaloid known as esophageal carcinogen. NNN is the cause of esophageal and oral cavity cancer in smokers and snuff dippers. The studies showed that the carcinogenicity of (S)-NNN, the predominant enantiomer in tobacco products, may be greater than that of (R)-NNN or racemic NNN.

Stability Light Sensitive
Applications Labelled NNK (M325750). This compound was present in the highest concentrations in smokeless tobacco out of the nitrosamines identified. It is likely to be important in the etiology of cancers of the lung, oral cavity, and pancreas in people who use tabacco products. Readily produces cancer in rats and hamsters. Carcinogen.
