Product Description
HBED di-HCl is an orally bioactive hexadentate phenolic aminocarboxylic acid iron chelator. HBED refers to N,N'-bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid, which induces iron excretion in primates. HBED di-HCl has potential as an alternative to deferoxamine for iron chelation therapy.
HBED dihydrochloride (CAS#: 35369-53-0) is an orally bioactive hexadentate phenolic aminocarboxylic acid iron chelator. It refers to N,N'-bis(2-hydroxybenzyl)ethylenediamine-N,N'-diacetic acid, which induces iron excretion in primates. The compound has the molecular formula C20H26Cl2N2O6 and a molecular weight of 461.34 g/mol. It appears as a solid and should be stored as powder at -20°C for up to 3 years or at 4°C for up to 2 years, and in solvent at -80°C for up to 6 months or at -20°C for up to 1 month. The compound has a purity of ≥98%. It has potential as an alternative to deferoxamine in iron chelation therapy. Iron chelation therapy is used to treat iron overload disorders such as thalassemia and hemochromatosis, where excess iron accumulates in tissues and causes organ damage. The compound's hexadentate structure allows it to bind iron with high affinity and selectivity.
Biological Activity I Assay Protocols (From Reference)
Targets
HBED dihydrochloride targets iron, functioning as a hexadentate chelator that binds iron with high affinity and induces iron excretion. Iron is an essential element that plays a critical role in various physiological processes including oxygen transport, electron transfer, and DNA synthesis. However, excess iron can be toxic, leading to oxidative stress and organ damage. Iron chelators are used to treat iron overload disorders such as thalassemia, hemochromatosis, and myelodysplastic syndromes. The compound's phenolic aminocarboxylic acid structure provides multiple coordination sites that allow it to bind iron with high affinity and selectivity. Its oral bioavailability makes it a promising alternative to deferoxamine, which requires parenteral administration. The compound induces iron excretion in primates, demonstrating its efficacy in vivo. Its mechanism of action involves binding to excess iron in the body and facilitating its excretion through the urine and feces.
ln Vitro
In vitro, HBED dihydrochloride is used as an iron chelator in biochemical research. The compound's ability to bind iron can be studied using various analytical techniques including UV-Vis spectroscopy, potentiometry, and mass spectrometry. Its iron-binding affinity and selectivity can be assessed by comparing its binding constants with those of other chelators. In cell culture, the compound may be used to study the effects of iron depletion on cellular processes including proliferation, differentiation, and oxidative stress. Its oral bioavailability makes it suitable for development as a therapeutic agent for iron overload disorders. The compound may also be used in studies of iron metabolism and homeostasis.
ln Vivo
varied administration techniques result in varied activity from HBED monohydrochloride dihydrate. At dosages of 81, 162, and 324 μMol/kg, oral administration of HBED did not result in any significant effects. On the other hand, following subcutaneous delivery, dosages of 162 and 324 μMol/kg enhanced net iron excretion [1].
Cell Assay
Cellular assays for HBED dihydrochloride involve treating cells with the compound and assessing its effects on iron levels, oxidative stress, and cell viability. Cells are treated with the compound at various concentrations, and intracellular iron levels are measured using colorimetric or fluorescent assays. Oxidative stress markers such as reactive oxygen species and lipid peroxidation are assessed. Cell viability is measured using MTT or similar assays. The compound's effects on iron-dependent cellular processes including proliferation, differentiation, and apoptosis are evaluated. These assays are used to study the compound's mechanism of action and its potential as an iron chelation therapy.
Animal Protocol
Animal studies for HBED dihydrochloride have demonstrated that the compound induces iron excretion in primates. In these studies, the compound is typically administered orally to animals, and iron levels in urine and feces are measured. The compound's efficacy in reducing iron burden is assessed by measuring tissue iron levels in the liver, heart, and other organs. The compound's oral bioavailability and pharmacokinetic properties are also evaluated. In animal models of iron overload, the compound's ability to prevent or reverse iron-induced organ damage is assessed. These studies support the compound's potential as an alternative to deferoxamine in iron chelation therapy.
ADME/Pharmacokinetics
Pharmacokinetic data for HBED dihydrochloride indicate that it is orally bioactive. The compound is absorbed from the gastrointestinal tract and distributed to tissues where it binds iron. The compound induces iron excretion in primates, indicating that it is effective in vivo. Its pharmacokinetic properties make it a promising alternative to deferoxamine, which requires parenteral administration. However, comprehensive pharmacokinetic studies including absorption, distribution, metabolism, and excretion are limited. The compound's stability in solution has rarely been reported.
