General description
Cyclen is a microcyclic tetramine that can be used as a ligand that forms a co-ordination linkage with the surface metal cations. It can be used as a synthetic precursor. It can be prepared by S-alkylation of dithiooxamide with an excess amount of bromoethane.
Application
Cyclen is an azamocrocycle, which can be used in the development of fluorescent nanosensors for the detection of metal ions.

Pseudocontact shifts (PCS) from paramagnetic lanthanide ions present powerful long-range structural restraints for structural biology by NMR spectroscopy, but site-specific tagging of proteins with lanthanides remains a challenge, as most of the available lanthanide tags require proteins with single cysteine

Differences in tissue pH can be diagnostic of cancer and other conditions that shift cell metabolism. Paramagnetic probes are promising tools for pH mapping in vivo using magnetic resonance spectroscopy (MRS) as they provide uniquely shifted MR signals that change
