  • Synthesis and Characterization of Various Benzyl Diethylenetriaminepentaacetic Acids (dtpa) and Their Paramagnetic Complexes, Potential Contrast Agents for Magnetic Resonance Imaging

    Four derivatives of diethylenetriaminepentaacetic acid (= 3,6,9-tris(carboxymethyl)-3,6,9-triazaundecane-dioic acid (H(5)dtpa)), potential contrast agents for magnetic resonance imaging (MRI), carrying benzyl groups at various positions of the parent structure were synthesized and characterized by a thorough multinuclear NMR study, i.e., the (S)- and (R)-stereoisomers 1a and 1b of 4-benzyl-3,6,9-tris(carboxymethyl)-3,6,9-triazaundecanedioic acid (H-5[(S)-(4-Bz)dtpa] and H-5[(R)-(4-Bz)dtpa] the diamide derivative N,N'-bis[benzylcarbamoyl)methyl}diethylenetriamine-N,N',N "-triacetic acid (= 3,9-bis[2-(benzylamino)-2-oxoethyl]-6-(carboxymethyl)-3,6,9-triazaundecanedioic acid: H-3[dtpa(BzA)(2)]: 2), and the diester derivative N,N "-bis([(benzyloxy)carbonyl]methyl]diethylenetriamine-N,N',N "-triacetic acid (= 3,9-bis[2-(benzyloxy)-2-oxoethyl]-6-(carboxymethyl)-3,6,9-triazaundecanedioic acid; H-3[dtpa(BzE)(2)]: 3). From the O-17-NMR chemical shift of H2O induced by their dysprosium complexes with ligands 1-3, it was concluded that only one H2O molecule is contained in the first coordination sphere of these lanthanide complexes. The rotational correlation times (tau(R)) of the complexes were estimated from the H-2-NMR longitudinal relaxation rate of the deuterated diamagnetic lanthanum complexes. The exchange lime of the coordinated H2O molecule (tau(M)) was studied through the temperature dependence of the O-17-NMR transverse relaxation rate. As compared to [Gd(dtpa)](2), the H2O-exchange rate is faster fur [Gd(S)-(4-Bz)dtpa}](2) and [Gd(R)-(4-Bz)dtpa}](2)-, slower for [Gddtpa(BzA)(2)}], and almost identical for [Gddtpa(BzE)(2)}]. The analysis of the H-1-relaxivity of the gadolinium complexes recorded from 0.02 to 300 MHz established that i) the relaxivity of [Gddtpa(BzE)(2)}] is similar to that of [Gd(dtpa)](2-), ii) the slightly slower molecular rotation of [Gddtpa(BzA)(2)}] induces a mild enhancement of its relaxivity, and iii) the marked increase of relaxivity of [Gd(S)-(4-Bz)dtpa}](2) and [Gd(R)-(4-Bz)dtpa}](2-) mainly results from an apparently shorter distance between the gadolinium ion and the H2O protons of the coordinated H2O molecule.

    kinetic inertness of the complexes was also higher than Omniscan® and comparable to another commercial MRI contrast agent Gd-DTPA (Magnevist®). Meanwhile, the viability of HeLa cells remained unaffected after the exposure to the complexes. The efficacy of these complexes as potential positive contrast agents in MRI was further evaluated using in vivo studies, and the complexes were found to exhibit superb
