Structure-Activity Relations in Carcinogenesis by N-Nitroso Compounds,structures have been carried out with the aim of using the differences in activity to suggest possible mechanisms of their carcinogenic action. This approach, which is common in pharmacology, has proved very useful.

Comparison of Mutagenic and Carcinogenic Properties,ons of each test system have become topics of scientific investigation and discussion, especially because of the role they play in regulatory policies. The purpose of organizing this volume was an attempt to examine and compare the genotoxic properties of one extensively studied class of compounds, namely, N-nitroso compounds.

Effects of pH and Structure on the Mutagenic Activity of N-Nitroso Compounds,itions..The contribution to human cancer caused by continued exposure to low levels of N-nitroso compounds is uncertain, but exposure of pregnant mice to levels of 10 ppb of DMN resulted in significant lung tumor formation in the male progeny.. A generalized scheme for the metabolism and decomposition of N-nitroso compounds is given in Figure 1..

A detailed investigation of the toxicity of nitrosodimethylamine began in England in the 1950s as a result of another accidental poisoning, the first results being reported
