1H and 13C spectral assignments of an oxytocin-DTPA derivative, a ligand for potential receptor-specific MRI contrast agents.
A new potential ligand for paramagnetic complexes acting as a receptor-specific MRI contrast agent was investigated by means of one- and two-dimensional NMR spectroscopy and mass spectrometry. A complete assignment of the structure is reported.
