suberate (octanedioate)

suberate (octanedioate) (CAS No.: 505-48-6) is a medium-chain dicarboxylic acid widely utilized as a biochemical intermediate and metabolic probe in studies of fatty acid oxidation and mitochondrial function. As a downstream oxidation product of unsaturated fatty acids such as oleic acid, suberate is frequently detected in biological fluids and serves as a marker associated with perturbations in β-oxidation pathways and carnitine-dependent acyl transport processes. Elevated levels of this metabolite have been correlated with deficiencies in enzymes involved in mitochondrial fatty acid metabolism, including medium-chain acyl-CoA dehydrogenase and carnitine-acylcarnitine translocase, making it a useful analytical indicator in mechanistic investigations of inherited metabolic disorders. At the cellular level, suberate has been reported to modulate signaling pathways such as Akt, as well as downstream networks including TGF-β and MAPK cascades, suggesting broader roles in cellular stress responses and metabolic regulation. Its biological activity is generally characterized in the low micromolar to millimolar concentration range depending on the experimental system. In research settings, suberate is applied in metabolomic profiling, pathway elucidation, and functional assays using cell-based or in vivo models to investigate mitochondrial dysfunction and lipid metabolism, with experimental concentrations tailored to specific study designs and objectives.
