  2,2'-[bis(N-bromoethylcarbonyl)amino]biphenyl 、 1,4,7,10-四氮杂环十二烷-1,4,7-三乙酸三叔丁酯 在 potassium carbonate 作用下， 以 乙腈 为溶剂， 反应 18.0h， 以63%的产率得到Tert-butyl 2-[4,7-bis[2-[(2-methylpropan-2-yl)oxy]-2-oxoethyl]-10-[2-oxo-2-[2-[2-[[2-[4,7,10-tris[2-[(2-methylpropan-2-yl)oxy]-2-oxoethyl]-1,4,7,10-tetrazacyclododec-1-yl]acetyl]amino]phenyl]anilino]ethyl]-1,4,7,10-tetrazacyclododec-1-yl]acetate

  Gd Complexes of DO3A-(Biphenyl-2,2′-bisamides) Conjugates as MRI Blood-Pool Contrast Agents

  摘要：

  We report the synthesis of DO3A derivatives of 2,2'-diaminobiphenyl (1a,b) and their Gd complexes of the type [Gd(1)(H2O)]center dot xH(2)O (2a,b) for use as new MRI blood-pool contrast agents (BPCAs) that provide strong and prolonged vascular enhancement. Pharmacokinetic inertness of 2 compares well with that of structurally related Dotarem, a DOTA-based MRI CA currently in use. The R-1 relaxivity in water reaches 7.3 mM(-1) s(-1), which is approximately twice as high as that of Dotarem (R-1 = 3.9 mM(-1) s(-1)). They show interaction with HSA to give association constants (K-a) in the order of two (similar to 10(2)), revealing the existence of the blood-pool effect. The in vivo MR images of mice obtained with 2 are coherent, showing strong signal enhancement in both heart, abdominal aorta, and small vessels. Furthermore, the brain tumor is vividly enhanced for an extended period of time.
