Usage

Uses

Used in Heavy Metal Poisoning Treatment:
TEC cyclen is used as a chelating agent in the treatment of heavy metal poisoning, particularly for metals with high affinity such as copper. It helps to bind and remove toxic metal ions from the body, providing a therapeutic solution for heavy metal exposure.
Used in Medical Imaging and Diagnostics:
In the medical field, TEC cyclen is used in the synthesis of radioactive metal chelates for imaging and diagnostic purposes. Its strong coordination with metal ions allows for the development of effective imaging agents that can be used to detect and monitor various medical conditions.
Used in Industrial Applications:
TEC cyclen's ability to bind and remove metal ions also makes it useful in various industrial applications. It can be employed in processes that require the removal of metal contaminants or the recovery of valuable metal ions from solutions, contributing to cleaner and more efficient industrial operations.

Compositions for protecting skin

The purpose of the present invention is to provide a skin outer layer composition which does not have or has very low skin irritation or toxicity, and has a high ability to remove formaldehyde and heavy metals compared to conventional material. The present invention provides the skin outer layer composition comprising, as active ingredients, one or more selected from trientine or trientine derivatives represented by chemical formula 1, cyclen or cyclen derivatives represented by chemical formula 2, and cyclam or cyclam derivatives represented by chemical formula 3. In the above formulas, R_1, R_2, R_3, R_4, R_5 and R_6 are each independently hydrogen, -R_7-COOH or salts thereof, and R_7 is a C_1-C_5 aliphatic group, a substituted or unsubstituted aromatic group, or a heterocyclic six-membered or five-membered ring.COPYRIGHT KIPO 2018

Synthesis of macrocyclic bifunctional chelating agents: 1,4,7-tris(carboxymethyl)-10-(2-aminoethyl)-1,4,7,10-tetraazacyclododecane and 1,4,8-tris(carboxymethyl)-11-(2-aminoethyl)-1,4,8,11-tetraazacyclotetradecane

The convenient, synthetically useful bifunctional chelating agents, 1,4,7-tris(carboxymethyl)-10-(2-aminoethyl)-1,4,7,10-tetraazacyclododecane and 1,4,8-tris(carboxymethyl)-11-(2-aminoethyl)-1,4,8,11- tetraazacyclotetradecane, were obtained by reaction of ethyl bromoacetate with 1,4,7,10-tetraazacyclododecane and 1,4,8,11-tetraazacyclotetradecane, followed by reaction with N-(2-bromoethyl)phthalimide. This method is proven to be more efficient to prepare bifunctional chelating agents with aliphatic side arms in high yields, above 53%.

A convenient, novel approach for the synthesis of polyaza macrocyclic bifunctional chelating agents

The convenient synthetically useful bifunctional chelating agents, (10-p-aminobenzyl)-1,4,7,10-tetraazacyclododecane-1,4,7-triacetate (p-ABz-DO3A) 3 and (11-p-aminobenzyl)-1,4,8,11-tetraazacyclotetradecane-1,4,8-triacetate (p-ABz-TE3A) 6, were obtained by reaction of an ethyl bromoacetate with 1,4,7,10-tetraazacyclododecane and 1,4,8,11-tetraazacyclotetradecane followed by reaction with nitrobenzyl bromide. This method proved more efficient than any described in the literature since the overall yield in a two-step synthesis sequence starting from tetraazamacrocycles was 68%.
