| | N-(2-Hydroxyethyl)ethylenediaminetriacetic acid Usage And Synthesis |
| Chemical Properties | Crystalline | | Uses | Chelating compound. | | Uses | N-(2-Hydroxyethyl)ethylenediaminetriacetic acid is a chelating agent. | | in vivo | EDTA-OH (50 mg/kg, i.p. for 5 days) decreases the aluminium concentration in blood and brain and oxidative stress in brain. EDTA-OH is blood-brain barrier permeable, which could be an antidote for aluminium overload[3]. | Animal Model: | Aluminium overload in wistar rats[3] | | Dosage: | 50 mg/kg | | Administration: | i.p. for 5 days | | Result: | Inhibited GST activity, reduced the concentration of aluminium in blood and brain. |
| | Purification Methods | Crystallise HEDTA from warm H2O, after filtering, by addition of 95% EtOH and allowing to cool. The crystals, collected on a sintered-glass funnel, are washed three times with cold absolute EtOH, then again crystallised from H2O. After leaching with cold H2O, the crystals are dried at 100o under vacuum. [Spedding et al. J Am Chem Soc 78 34 1956, Beilstein 4 IV 2449.] |
