The Effect of N-nitrosation of Secondary Amines in Vitro by Fermented Celery Powder
Abstract:N-nitrosaminesis a kind of poison which can induce cancer. Nitrite can react withsecondary amines to form N-nitrosamines in meat production. The objective of this experiment was to study N-nitrosamines formation ofthree kinds offermentationcelery powder (FCP506, FCP504, and FCP-homemade) and nitritein vitro nitrosation reaction system bydifferent pH, temperature, and the ratio of the s...
متن کاملCopper(II)-catalyzed oxidative N-nitrosation of secondary and tertiary amines with nitromethane under an oxygen atmosphere.
The combination of a catalytic amount of Cu(OTf)2 and less than a stoichiometric amount of 1,8-diazabicyclo[5.4.0]undec-7-ene (DBU) under an O2 atmosphere effectively promoted the N-nitrosation of both secondary aromatic/aliphatic amines and tertiary aromatic amines with nitromethane (CH3NO2) leading to the preparation of N-nitrosamine derivatives.
متن کاملN-Cyanation of Secondary Amines Using Trichloroacetonitrile.
A one-pot N-cyanation of secondary amines has been developed using trichloroacetonitrile as an inexpensive cyano source. A diverse range of cyclic and acyclic secondary amines can be readily transformed into the corresponding cyanamides in good isolated yields, with the method successfully utilized in the final synthetic step of a biologically active rolipram-derived cyanamide. This approach ex...

Characterization of bacterial cytochrome cd(1)-nitrite reductase as one enzyme responsible for catalysis of nitrosation of secondary amines.
Bacterial formation of carcinogenic N-nitroso compounds may play a role in the etiology of human cancer. Biochemical and immunological studies in denitrifying bacteria (Pseudomonas aeruginosa) strongly support the identification of cytochrome cd(1)-nitrite reductase as the enzyme responsible for the catalysis of nitrosation through the production of nitric oxide or NO(+)-like species. Interesti...
