N-(2-furoyl)glycine

N-(2-furoyl)glycine (CAS No.: 5657-19-2) is an endogenous small-molecule metabolite detected in human urine, arising primarily from hepatic biotransformation of dietary and xenobiotic furan-containing compounds, including metabolites associated with coffee consumption and furfural exposure. As a conjugated glycine derivative of furoic acid, it is widely recognized as a non-invasive biomarker for assessing exposure to furan-related compounds and for investigating metabolic responses to dietary intake. Its formation reflects phase II detoxification processes, particularly glycine conjugation pathways involved in xenobiotic clearance, making it a valuable probe for studying liver metabolism and systemic metabolic flux. Although no direct molecular targets or signaling pathways have been definitively established, N-(2-furoyl)glycine is frequently utilized in metabolomics and pharmacokinetic studies to profile biochemical pathway activity and to support biomarker discovery in disease-related metabolic perturbations. In experimental settings, it is commonly employed as an analytical reference standard or as a monitored metabolite in biofluids, with concentration ranges in biological samples typically falling within low micromolar levels depending on exposure conditions. Its application spans in vitro assays, preclinical models, and high-throughput metabolomic analyses, where dosing or measurement parameters are adjusted according to specific study designs and analytical requirements.
