Triethylenetetramine Dihydrochloride

Triethylenetetramine Dihydrochloride (CAS No.: 38260-01-4) is a synthetic polyamine derived small molecule and a copper selective metal chelator that is broadly categorized as a chemical biology and disease mechanism research tool for studies of metal ion homeostasis, oxidative stress biology, and copper dependent cellular processes in biomedical research and early drug discovery workflows. Functionally, this compound is used to sequester labile Cu(II) pools and thereby modulate copper availability in biochemical and cellular systems, with downstream effects that are commonly investigated in pathways linked to redox regulation, mitochondrial function, metalloprotein activity, angiogenesis associated signaling, and apoptosis related stress responses, while mechanistic studies in oncology and metabolic disease models also examine proposed relationships to telomerase associated regulation and copper dependent enzyme networks. Reported activity in the literature is generally described through chelation driven functional responses rather than a single canonical receptor potency metric, and concentration dependent effects in vitro are typically observed from micromolar to low millimolar experimental windows depending on medium composition, copper burden, exposure duration, and model context, whereas quantitative potency endpoints such as IC50 or EC50 are assay specific and should be established under controlled conditions for each platform. In practical use, Triethylenetetramine Dihydrochloride is frequently applied in cell based perturbation studies, mechanistic phenotypic assays, and exploratory in vivo models of copper overload or copper dysregulation, as well as in screening cascades that profile copper chelation mediated rescue or sensitization phenotypes, and the concentrations or doses used in experiments typically depend on specific experimental designs and research objectives.
