Carbonyl compounds (RCS)

Carbonyl compounds constitute a broad chemical class characterized by a carbon-oxygen double bond, including aldehydes, ketones, and carboxylic acids. In a therapeutic and pathological context, the term generally refers to Reactive Carbonyl Species (RCS), which are highly reactive metabolic intermediates generated through lipid peroxidation, glycation, and oxidative stress (PMID: 18501201). Excessive accumulation of these compounds, known as carbonyl stress, leads to the covalent modification of proteins and DNA, resulting in the formation of Advanced Glycation End-products (AGEs) and Advanced Lipoxidation End-products (ALEs) (PMID: 10333930). These modifications are heavily implicated in the progression of chronic diseases, particularly diabetic complications, atherosclerosis, and neurodegenerative disorders like Alzheimer's disease (PMID: 31747808). Because 'Carbonyl compounds' is a broad chemical designation rather than a specific biological entity, it is not considered a discrete therapeutic target in the traditional sense. Instead, pharmacological intervention focuses on using chemical scavengers like hydralazine to neutralize these molecules or targeting specific enzymes involved in their detoxification, such as the glyoxalase system or carbonyl reductases (PMID: 15157303).
