2,8-Quinolinediol

2,8-Quinolinediol (CAS No.: 15450-76-7) is a quinoline-derived small molecule recognized as an endogenous metabolite and widely utilized as a biochemical reagent in life sciences research, particularly in studies related to cellular metabolism, oxidative stress, and neurobiology. Characterized by multifunctional chemical reactivity, it is capable of modulating metal ion chelation and redox processes, thereby influencing reactive oxygen species homeostasis, membrane integrity, and intracellular signaling pathways associated with cellular stress responses and metabolic regulation. Emerging evidence indicates that altered levels of this metabolite may be associated with pathological conditions, including cognitive impairment in patients undergoing hemodialysis, suggesting potential relevance in disease-related metabolic profiling. In experimental settings, 2,8-Quinolinediol is employed in enzyme activity assays, cell-based models, and mechanistic studies investigating interactions with biomacromolecules and redox-sensitive pathways, although its precise molecular targets remain to be fully elucidated. Its biological effects are typically observed in the low micromolar to micromolar concentration range depending on assay conditions, and it serves as a versatile tool in drug discovery, biomaterials research, and the development of models for studying oxidative damage and signaling dysregulation, with dosing and application parameters varying according to specific experimental objectives.
