Pentetic acid is a pentacarboxylic acid. It has a role as a copper chelator. It is a conjugate acid of a pentetate(1-).|Pentetic acid, also known as diethylenetriaminepentaacetic acid (DTPA), is a synthetic polyamino carboxylic acid with eight coordinate bond forming sites that can sequester metal ions and form highly stable DTPA-metal ion complexes. DTPA, along with its calcium and zinc trisodium salts, are the only FDA approved agents for the treatment of internal contamination by transuranics. It is currently considered, in all the dosage forms, as a member of the list of approved inactive ingredients for drug products by the FDA. DPTA was developed by the pharmaceutical company CIS US and FDA approved on April 14, 2004.|Pentetic acid is a Lead Chelator. The mechanism of action of pentetic acid is as a Lead Chelating Activity.|Pentetic Acid is an edetate and a chelating agent used in preparing radiopharmaceuticals. Pentetic acid (DTPA) has strong affinity for iron but also shows affinities for other heavy metals, thereby is used in the treatment of iron-storage disease and poisoning from heavy and radioactive metals. DTPA may chelate metallic moieties of unbound, extracellular radioimmunotherapeutics, thereby aggregating radioimmunotherapeutics locally to higher concentrations, and improving tumor cell radiocytotoxicity, while sparing normal tissues from the radiocytotoxic effects. In addition, DTPA is used in radioimaing procedures when complexes with radioisotopes, ex., Tc 99m or In 111.|An iron chelating agent with properties like EDETIC ACID. DTPA has also been used as a chelator for other metals, such as plutonium.
