Maleimide-DTPA

Maleimide-DTPA (MDTPA) is a monoreactive DTPA derivative (MDTPA) with maleimide group as peptide binding site, which can be combined with radionuclides to prepare radionuclide conjugates (RDC) . Maleimide-DTPA can chelate indium-111 (111In) and label peptides and peptides with indium-111. For example, it has high stability when combined with OST7 incubated in human serum, which is better than cyclic cDTPA. Maleimide-DTPA is a good material for medical imaging or treatment.
