Nitroso derivatives with unique characteristics have been extensively studied in various fields, including biology and clinical research. Although there has been substantial investigation of "nitrosable" components in many drugs and commonly consumed nutrients, there is still a need for a higher awareness about their formation and characterization. This study demonstrates how these derivatives can be produced through a mechanochemical procedure under solid-state conditions. The results include synthesizing previously unknown compounds with potential biological and pharmaceutical applications, such as a nitrosamine derived from a Diclofenac-like structure.

Nitroso groups are widely present in biologically active compounds in medicinal chemistry, and nitroso compounds serve as important building blocks in organic chemistry and materials science. Nitrosoarenes, in particular, showcase remarkable versatility, functioning as both electrophilic and nucleophilic reagents in a broad spectrum of organic reactions, thereby holding significant relevance in organic chemistry. This review aims to provide a comprehensive overview of the latest advancements in nitrosoarene reactions spanning a decade.

Disulfide-containing nitrosoarenes with [bis(4-nitrosobenzyl) disulfide, ()] or without [4-nitrosophenyl disulfide, (), and 1,2-bis(4'-nitroso-[1,1'-biphenyl]-4-yl)disulfane, ()] an alkyl spacer between the sulfur headgroup and the aromatic moiety (phenyl in () or biphenyl in ()) were synthesized and used as precursors to form azodioxy thiolate films on Au(111) substrates. Due to the incorporated disulfide functionalities, these specifically designed nitrosoarenes are enabled to self-polymerize through azodioxy bonds on a gold surface. Thin films of (), (), and () were prepared at different adsorption times via the solution-phase self-assembly of molecules onto the Au(111) surface and characterized by Raman spectroscopy, ellipsometry, water contact angle measurements, atomic force microscopy (AFM), and scanning tunneling microscopy (STM).

The increasing complexity of food production and processing has raised concerns regarding food process contaminants, which pose significant public health risks. Food process contaminants can be introduced during diverse phases of food processing such as drying, heating, grilling, and fermentation, resulting in the synthesis of harmful chemicals including acrylamide (AA), advanced glycation end products (AGEs), heterocyclic aromatic amines (HAAs), furan and its naturally occurring derivatives, polycyclic aromatic hydrocarbons (PAHs), N-nitroso compounds (NOCs), 2-chloropropane-1,2-diol esters (2-MCPDE), and 3-chloropropane-1,2-diol esters (3-MCPDE), ethyl carbamate (EC), glycidyl esters (GE), and 4-methylimidazole (4-MEI), all of these are harmful to human health. Although these compounds can be somewhat prevented during processing, eliminating them can often be challenging due to their unknown formation mechanism.

Nitrites in meat products are important food additives with coloring, antibacterial and antioxidant effects, but excessive intake of nitrites can pose health risks, including an increased risk of cancer due to the formation of carcinogenic nitrosamines. In the present study, Limosilactobacillus fermentum CGMCC 1.7434 was screened and the effects of it and Debaryomyces hansenii GDMCC 2.
