CAS 137076-54-1: TRI-TERT-BUTYL 1,4,7,10-TETRAAZACYCLODODECANE-TETRAACETATE

t-Butyl ester-protected DOTA derivative allows the selective conjugation of the macrocyclic chelator to peptides during Fmoc-SPPS. DOTA forms highly stable chelates with radioactive isotopes of Ga,In,and Y, as well as with radionuclides of Lu, Gd, and other lanthanides.

Tri-tert-butyl 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetate (TBA) is a gadolinium chelate that is used as a contrast agent in magnetic resonance imaging. TBA binds to the malignant cells and shows an increase in uptake of the gadolinium contrast agent. TBA has been shown to be effective in the diagnosis of cancerous brain tissue and is also able to detect cancer cells in animals. TBA has shown some efficacy against bacterial infection by binding to the cell membrane and inhibiting protein synthesis. It is also able to act synergistically with antibiotics such as penicillin or ampicillin to kill bacteria more effectively.

DOTA-tri(t-butyl ester) is used to make G3 MRI contrast agents for MR angiography and tumor imaging.

Applications DOTA-tris (t-Bu ester), is a Bifunctional chelator, that can be used in the preparation of gadolinium complexes as MRI blood contrast agents.

DOTA-tris(tBu)ester

DOTA(tBu)3-OH is a Building Block that is used in peptide synthesis. It can be used as a condensation reagent or as a building block for the synthesis of peptides and antibodies. DOTA(tBu)3-OH is also an additive for labelling and building blocks for peptide synthesis. DOTA(tBu)3-OH is stable and not toxic to cells, making it useful in cell culture applications. It has been shown to react with the side chain amino groups of lysine residues on proteins, including antibody molecules.
