| Chemical Properties | Colourless crystals | | Uses | Bifunctional DOTA aconjugates to peptides and has become an established strategy for constructing target-specific metal containing agents including targeted MRI contrast agents and diagnostic and ther
apeutic radiopharmaceuticals. | | Uses | 1,4,7,10-Tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) is a macrocyclic complexing agent.- It has been used for radiolabeling of carbon nanotube bioconjugates by chelating 64Cu radioisotope.
- DOTA can be activated with N-hydroxysulfosuccinimidyl for conjugation with monoclonal antibodies in clinical radioimmunotherapy.
- It can form complexes with gadolinium for application as MRI contrast agents.
- Metal complexes of DOTA-peptide conjugates can be used as therapeutic radiopharmaceuticals.
| | Definition | ChEBI: An azamacrocyle in which four nitrogen atoms at positions 1, 4, 7 and 10 of a twelve-membered ring are each substituted with a carboxymethyl group. |
