proven (III)的配合物已被证明是特别有效的磁共振成像(MRI)造影剂。实现更敏感的基于小g的MRI造影剂的一种基本策略是增加水合数q,以提高松弛度。在这项工作中,合成了一系列带有3个配位水分子的二亚乙基三胺-N-氧化物五乙酸-双酰胺基Gd(III)配合物,其中的水合数通过发光测量来验证。所有复合物的弛豫度约为市售MRI造影剂的三倍,范围为12.5至18.8 mM -1 s -1(1.5 T; 25°C)。使用HYPERQUAD程序在25°C下由电位滴定数据计算出Gd(III)配合物的形成常数,该常数证明了其优于商用MRI造影剂Gd-DTPA-BMA(Omniscan®)的稳定性。配合物的动力学惰性也高于Omniscan®,可与另一种商用MRI造影剂Gd-DTPA(Magnevist®)相提并论。同时,暴露于复合物后,HeLa细胞的活力仍不受影响。使用体内研究进一步评估了这些复合物

gadolinium complexes of [bis(R-amide)dtpaH3] (where R = Pri,, Bui,, Bz and phenylethyl, L1--L4)) with potential application as contrast agents for magneticresonanceimaging has been prepared and characterized ; the relaxivity of these complexes is comparable to the contrast agent [Gd(dtpa)(H2OO)]; which is which is currently used in clinics; the X-ray structure analysis of the gadolinium(III) complex of L3

kinetic inertness of the complexes was also higher than Omniscan® and comparable to another commercial MRIcontrastagent 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 contrastagents in MRI was further evaluated using in vivo studies, and the complexes were found to exhibit superb
