Cyclen

Description:

Cyclen, or 1,4,7,10-tetraazacyclododecane, is a cyclic polyamine characterized by its unique structure, which consists of a twelve-membered ring containing four nitrogen atoms and eight carbon atoms. This compound is known for its ability to form stable complexes with metal ions, making it valuable in various applications, including coordination chemistry and medicinal chemistry. Cyclen exhibits a high degree of flexibility due to its cyclic nature, which allows it to adapt to different geometries when binding to metal ions. Its nitrogen atoms can act as Lewis bases, facilitating the formation of chelate complexes. Cyclen is also soluble in water and organic solvents, enhancing its utility in biological systems. Additionally, it has been studied for its potential use in drug delivery and as a contrast agent in magnetic resonance imaging (MRI) due to its ability to encapsulate metal ions. Overall, cyclen's unique structural and chemical properties make it a significant compound in both research and practical applications.

Cyclan is an aza-crown ether (analogous to crown-ethers) with a molecular formula (CH2CH2NH)n, where n is 3 to 6. In the case of cyclan, or 1,4,7,10-Tetraazacyclododecane, its structure is formed by 4 units of CH2CH2NH (n=4). In chemical synthesis, the hydrogen atoms of the amine groups in cyclan are substituted by different functional groups to yield a series of modified 1,4,7,10-Tetraazacyclododecane or cyclans, which can be used as chelating agents.
