exocylic imine groups bearing a range of substituents. The zinc complexes can be quantitatively and rapidly transmetallated to the corresponding copper complexes and this route or direct reaction with the free ligand can be used to radiolabel the monomericspecies with (64)Cu. In vivo and in vitro studies of one of the (64)Cu imine complexes shows substantial hypoxic selectivity and high tumour uptake in

metal center to be in an N2S2 distorted square planar coordination geometry. Electrochemical measurements show that the copper(II) complexes undergo a reversible reduction attributable to a Cu(II)/Cu(I) process. The ligands and the copper(II) complexes featuring a carboxylicacid functional group have been conjugated to the tumor targeting peptide bombesin(7−14)-NH2. The bifunctional peptide conjugates
通过新的不对称双(硫代半碳zone酮)前体H 2 L 1的选择性转氨反应,制备了二乙酰基双(4-甲基硫代半碳carb酮)(H 2 atsm)的新双功能衍生物。新衍生物含有脂肪族羧酸(H 2大号2和H 2大号3),吨-丁基氨基甲酸叔丁酯(H 2大号4),或铵离子(H 2大号5)的官能团。新的配体和铜(II)配合物已通过NMR光谱,质谱和微分析进行了表征。复合铜II(L 4)在结构上通过X射线晶体学表征并且显示出金属中心处于N 2 S 2扭曲的正方形平面配位几何形状。电化学测量表明,铜(II)配合物经历可逆还原,这归因于Cu(II)/ Cu(I)过程。配体和具有羧酸官能团的铜(II)络合物已与靶向肿瘤的肽bomstin(7-14)-NH 2结合。。为了开发新的正电子发射断层扫描(PET)成像剂,将双功能肽偶联物用64铜进行了放射性标记。偶联物在室温和温和条件下以高放射化学纯度(> 95%)快速

Two new bifunctional chelators that are derivatives of the bis(thiosemicarbazone) ATSMH2 proligand have been prepared, one with two phenyl carboxylate substituents on the exocyclic nitrogens (L1H2) and one with a single phenyl carboxylate (L2H2). The new ligands have been characterised by NMR spectroscopy, mass spectrometry and in the case of L1H2 by X-ray crystallography. The copper, nickel and zinc complexes of the new ligands have been synthesised and characterised. Electrochemical measurements show that the copper(II) complexes undergo a reversible reduction attributable to a Cu(II)/Cu(I) process. The new proligands have been tethered to the N-α-Boc-protected amino acids lysine and ornithine using solution and solid phase methods. The new amino acid conjugates form copper complexes and the complexes have been characterised by mass spectrometry and electronic spectroscopy. The bifunctional chelator L2H2 has been conjugated to the tumour targeting peptide octreotide and the new ATSMH2âoctreotide conjugate and its copper complex have been characterized by mass spectrometry. These new systems have the potential to be used for new targeted copper radiopharmaceuticals for imaging and therapy.
