the synthesis and characterization of three new diphosphine ligands with polyether groups of general formula R(OCH 2 CH 2 ) n PPhCH 2 CH 2 PPh(CH 2 CH 2 O) n R: 1 (R = Me, n = 3), 2 (R = Bu, n = 3) and 3 (R = Bu, n = 4). trans-[ 99m TcO 2 L 2 ] + complexes were prepared by reaction between the diphosphine ligands and the 99m Tc-gluconate precursor. The homologous rhenium complexes, trans-[ReO 2 L 2
我们报告了三种具有通式 R(OCH 2 CH 2 ) n PPhCH 2 CH 2 PPh(CH 2 CH 2 O) n R: 1 (R = Me, n = 3) 的聚醚基团的新型二膦配体的合成和表征, 2 (R = Bu, n = 3) 和 3 (R = Bu, n = 4)。反式-[ 99m TcO 2 L 2 ] + 配合物通过二膦配体和99m Tc-葡萄糖酸盐前体之间的反应制备。通过与[ReO 2 py 4 ]Cl和葡萄糖酸氧铼(V)的配体取代反应合成了同源铼配合物,反式-[ReO 2 L 2 ]Cl (L=1,2,3),并通过红外表征, ESMS和'H, 13 C 1 H}, 31 P 1 H} NMR光谱。所有这些数据都与螯合到反式 ReO 2 单元的二膦配合物的形成一致。铼和 99m Tc 配合物的 HPLC 分析显示出非常相似的曲线和保留时间,与同源复合物的形成一致。对大鼠的初步生物分布研究显示三种
