tetradecanedioate

tetradecanedioate (CAS No.: 821-38-5) is an endogenous long-chain dicarboxylic fatty acid metabolite involved in lipid metabolism and energy homeostasis, and is increasingly utilized in biomedical research as a functional probe of membrane transport and metabolic regulation. This compound has been shown to interact with members of the organic anion transporting polypeptide (OATP) family, suggesting a role in modulating transporter-mediated uptake processes and influencing the disposition of structurally diverse substrates. As such, tetradecanedioate is widely regarded as a candidate endogenous biomarker for evaluating OATP activity and investigating transporter-mediated drug–drug interactions. Mechanistically, it is associated with pathways governing fatty acid oxidation and cellular lipid handling, and may indirectly reflect alterations in metabolic flux and membrane transport efficiency. Although detailed quantitative activity parameters are not consistently reported, its biological effects in experimental systems are typically observed within low micromolar to higher concentration ranges depending on assay conditions and model systems. In vitro and in vivo studies commonly employ tetradecanedioate in cell-based transport assays, metabolic profiling, and pharmacokinetic investigations, where concentrations or doses are adjusted according to specific experimental objectives. Its relevance in probing lipid metabolism, transporter function, and compound interaction networks makes it a valuable tool in drug discovery and mechanistic pharmacology research.
