reaction with the transition metals rhenium and technetium. An amphiphilic rhenium complex is synthesized by a transmetallation reaction with the zinc complex in presence of the polar phosphine sodium triphenylphosphine trisulfonate, which leads to a rhenium complex with a lipophilic dithiocarbamate and a polar phosphine ligand. The study of this rhenium complex has shown that it self-aggregates, leading
一种新的用棕榈酰基官能化的二硫代氨基甲酸锌被描述为通过与过渡金属rh和tech的金属转移反应制备金属表面活性剂的有用工具。通过在极性膦三苯基膦三磺酸钠的存在下与锌配合物发生金属转移反应,可以合成两亲性的complex配合物,从而生成具有亲脂性二硫代氨基甲酸酯和极性膦配体的rh配合物。对该complex配合物的研究表明它会自聚集,导致形成聚集体,这些聚集体已通过动态光散射和低温透射电子显微镜(cryo-TEM)进行了分析。此外,这种两亲性的complex络合物被掺入大豆磷脂酰胆碱脂质体中,脂质体是通过混合磷脂和en复合物还是通过将the复合物掺入预制脂质体中制备的。放射性化合物[99mTc(H2O)3(CO)3] +与上述二硫代氨基甲酸锌,膦三苯膦三磺酸膦钠和磷脂大豆磷脂酰胆碱的一锅反应,导致脂质体被标记为Tc-99m同源复合物根据高效液相色谱(HPLC)数据分析配合物。
