개요
Iminodiacetic acid is an amino dicarboxylic acid that is glycine in which one of the hydrogens attached to the nitrogen is substituted by a carboxymethyl group. It has a role as a chelator. It is a glycine derivative, an amino dicarboxylic acid and a non-proteinogenic alpha-amino acid. It is a conjugate acid of an iminodiacetate.

Mechanism of Action
LEAD NITRATE ALONE OR CHELATED WITH DIFFERENT CHELATING AGENTS INCL IMINODIACETIC ACID (IDA) WAS ADMIN TO PREGNANT RATS ON DAYS 9, 11 OR 16 OF GESTATION. THE LEAD-CHELATE COMPLEX EITHER REDUCED OR EQUALED BUT DID NOT ENHANCE THE OVERALL EMBRYO OR FETAL TOXICITY. THERE WERE NO QUALITATIVELY DIFFERENT EFFECTS PRODUCED WITH CHELATED LEAD VERSUS LEAD ALONE. THE CHELATING AGENTS WERE MORE EFFECTIVE AFTER DAY 9 THAN DAYS 11 OR 16. EDTA PRODUCED THE GREATEST REDUCTION IN OVERALL EFFECT, WHILE IDA PROVIDED THE LEAST PROTECTION.
MeSH Pharmacological ClassificationChemicals that bind to and remove ions from solutions. Many chelating agents function through the formation of COORDINATION COMPLEXES with METALS.
Absorption, Distribution and ExcretionPLACENTAL PERMEABILITY & TRANSFER OF LEAD NITRATE ALONE & CHELATED WITH IMINODIACETIC ACID (PBIDA) IN RATS WERE STUDIED. LITTLE OR NO DIFFERENCES IN MATERNAL BLOOD OR FETAL LEAD CONTENT WERE OBSERVED WITH PBIDA COMPLEX.
