Abstract: The problems of contamination of many products by nitroso compounds have been discussed since 1970's and have been partially solved, namely, the contamination by carcinogenic volatile N-nitrosamines. However, there is still a gap in knowing… read more here.

Abstract: N-Nitroso compounds (NOC) are known for the carcinogenicity of most members. However, 13% of 332 NOC reviewed in 1984 were found to be non-carcinogenic. The non-carcinogenicity of all N-nitrosamines with even one tertiary alkyl group… read more here.

Abstract: Herein, a photoinitiated radical relay reaction of quinoxalin-2(1H)-ones, with acyloxy nitroso compounds as a source of radicals, is described. Although the C-H functionalization of quinoxalin-2(1H)-ones has been investigated, its difunctionalization, the simultaneous construction of C-C… read more here.

DOI: 10.1080/13510002.2016.1168589
Abstract: Objective: We present evidence that nitrite and nitrosothiols, nitrosoamines and non-heme dinitrosyl iron complexes can reversibly inhibit catalase with equal effectiveness. Methods: Catalase activity was evaluated by the permanganatometric and calorimetric assays. Results: This inhibition… read more here.
