Nitrilotriacetic acid (NTA) is the aminopolycarboxylic acid with the formula N(CH 2 CO 2 H) 3. It is a colourless solid. It is a colourless solid. Its conjugate base nitrilotriacetate is used as a chelating agent for Ca 2+ , Co 2+ , Cu 2+ , and Fe 3+ .

Nitrilotriacetonitrile (NTAN) is a precursor for nitrilotriacetic acid (NTA, a biodegradable complexing agent and building block for detergents), for tris(2-aminoethyl)amine (a tripodal tetradentate chelating agent known under the abbreviation tren) and for the epoxy resin crosslinker aminoethylpiperazine.
An aminopolycarboxylic acid (sometimes abbreviated APCA) is a chemical compound containing one or more nitrogen atoms connected through carbon atoms to two or more carboxyl groups. Aminopolycarboxylates that have lost acidic protons form strong complexes with metal ions.
Nausea and vomiting are two of the most feared cancer treatment-related side-effects for people with cancer and their families. In 1983, Coates et al. found that people receiving chemotherapy ranked nausea and vomiting as the first and second most severe side-effects, respectively. [ 98 ]
Such substances are often similar in structure to the metabolite that they interfere with, such as the antifolates that interfere with the use of folic acid; thus, competitive inhibition can occur, and the presence of antimetabolites can have toxic effects on cells, such as halting cell growth and cell division, so these compounds are used in ...
DOTA is derived from the macrocycle known as cyclen.The four secondary amine groups are modified by replacement of the N-H centers with N-CH 2 CO 2 H groups. The resulting aminopolycarboxylic acid, upon ionization of the carboxylic acid groups, is a high affinity chelating agent for di- and trivalent cations.
As biodegradable alternatives from the class of widespread chelating agents, only nitrilotriacetic acid (NTA) is sufficiently biodegradable under certain conditions (which is suspected of being carcinogenic, though) and the chelating active amino acid derivatives β-alaninediacetic acid and methylglycine diacetic acid (Trilon M®).
