Chelation therapy is a medical procedure that involves the administration of chelating agents to remove heavy metals from the body. [1] Chelation therapy has a long history of use in clinical toxicology [2] and remains in use for some very specific medical treatments, although it is administered under very careful medical supervision due to various inherent risks, including the mobilization of ...
Ethylenediaminetetraacetic acid (EDTA), also called EDTA acid, is an aminopolycarboxylic acid with the formula [CH 2 N(CH 2 CO 2 H) 2] 2. This white, slightly water-soluble solid is widely used to bind to iron (Fe 2+ /Fe 3+) and calcium ions (Ca 2+), forming water-soluble complexes even at neutral pH. It is thus used to dissolve Fe- and Ca ...
A 2012 research review found that chelation wasn’t an effective treatment for autism, and children have died from receiving EDTA chelation therapy, according to the Centers for Disease Control ...
Although the concept and practical use of metal chelation is common, chelation of inert metals, such as platinum, has been rarely reported and the yield was extremely low. [2] To produce chelated platinum solution, tetraammonium EDTA , NTA, DTPA or HEDTA type chelating agent was mixed with platinum or platinum chemical compounds.

In vitro, EDTA, 1,10-phenanthroline and other chelating compounds lower the concentration of metal to the point where the metal is removed from the enzyme active site. Classical lock and key inhibitors such as phosphoramidon and bestatin bind tightly by approximating the transition state of the hydrolysis of the peptide, preventing it from ...
Sodium calcium edetate is in the chelating agent family of medication. [3] It is a salt of edetate with two sodium atoms and one calcium atom. [4] It works by binding to a number of heavy metals, which renders them almost inert and allows them to leave the body in the urine.
Treatment with chelating agents such as EDTA leads to complete inactivation. EDTA is a metal chelator that removes zinc, which is essential for activity. They are also inhibited by the chelator orthophenanthroline .
