The Dimercaptosuccinic acid, with its CAS registry number
2418-14-6, has the systematic name of 2, 3-disulfanylbutanedioic
acid. For being a kind of white crystalline powder, it is soluble
in caustic soda liquid. As to its usage, it is usually applied as
the intermediate of sodium dimercaptosuccinate, and it could also
be used as the detoxicant and health supplements.
DMSA/Dimercaptosuccinic Acid is indicated for the treatment of lead
poisoning in children with blood levelmeasured above 45 µg/dL.The
use of DMSA is not approved for prophylactic/prevention of lead
poisoning in anticipation of exposure in known lead contaminated
environments. Its elimination half-life is 2.5- 3.5 h. DMSA can
cross the bloodbrain barrier of mice, but not that of humans,
limiting its use to extracting heavy metals from parts of the body
other than the central nervous system.
Another application for DMSA is for provocation of tissue heavy
metals in anticipation of a urine test. This is sometimes called a
"challenge" or "provoked" heavy metals test. DMSA is used to help
mobilize heavy metals stored in body tissues (and therefore not
typically present in the circulation) and increase the excretion of
heavy metals in the urine. In a study by Howard Frumkin et al.,
this sort of test was shown to not reliably provide an indication
of past chronic mercury exposure, something it was often used for.
A 2004 study by GP Archbold, et al. called the results of a DMSA
challenge test "misleading" for the purposes of diagnosing mercury
toxicity. Moreover, DMSA share the limitation of extracellular
distribution, which makes it unable to cross the cell membrane and
chelate heavy metals from intracellular sites.
