개요
Succimer is a newly available oral chelator of lead and other heavy metals. The compound is indicated for the treatment of lead poisoning in children. Succimer does not bind iron, calcium or magnesium and preferentially binds lead, mercury and arsenic over copper or zinc. The metal-bound succimer is excreted in the urine. The drug may also be effective in adults.화학적 성질
white or off-white powder제조 방법
Isolate the solid complexes of trivalent lanthanide complexes with meso-2,3-Dimercaptosuccinic Acid, furan-2-carboxylic acid, meso-2,3-dimercaptosuccinic acid and sarcosine from the mixture of equimolar solutions of metal nitrates and ligands. Adjust the pH of the mixture to 7 by adding dilute solution of KOH. Reflux the mixture in ethanol (15-20 ml) for 3-4 hours on a steam bath. The clear solution gives a solid mass on cooling, filter through G4 glass crucible and wash several times with the mixture of doubly distilled water and alcohol. Recrystallise it to obtain pure crystal and dry at 60 ?? -70 ??C [1].
정의
ChEBI: A sulfur-containing carboxylic acid that is succinic acid bearing two mercapto substituents at positions 2 and 3. A lead chelator used as an antedote to lead poisoning.Pharmaceutical Applications
Dimercaptosuccinic acid (DMSA) is a modification of BAL containing two thiol groups, which are responsible for the unpleasant smell, and two carboxylic acid groups. DMSA is also known under the name Succimer. It chemical name is meso-2,3-dimercaptosuccinic acid and the chemical formula is HO2CCH(SH)CH(SH)CO2H. There are two diastereomeric forms, meso and the chiral DL forms, with the meso isomer being used as chelating agent.DMSA was developed in the 1960s and replaced BAL and edetate in some countries for the treatment of lead, arsenic and mercury poisoning. Furthermore, the dimethylester modification of DMSA has been successfully used for the treatment of heavy-metal poisoning.
Purification Methods
Purify the acid by dissolving it in NaOH and precipitating with dilute HCl, drying and recrystallising from MeOH. IR has at 2544 (SH) and max 1689 (CO2H) cm-1 . The bis-S-acetyl derivative has m 183-185o (from EtOAc or Me2CO), and its Me ester has m 119-120o (from pet ether) [Gerecke et al. Helv Chim Acta 44 957 1961, Owen & Sultanbawa J Chem Soc 3112 1949].
