Two luminescent ruthenium(II) polypyridine complexes appended with a D-fructose unit, [Ru(N^N)2(bpy-fructose)](PF6)2 (bpy-fructose = 4-(1-deoxy-D-fructos-1-yl)aminocarbonyl-4'-methyl-2,2'-bipyridine; N^N = 4,7-diphenyl-1,10-phenanthroline (Ph2-phen) (1a) and 2,2'-bipyridine (bpy) (2a)) and their D-fructose-free counterparts [Ru(N^N)2(bpy-Et)](PF6)2 (bpy-Et = 4-ethylaminocarbonyl-4'-methyl-2,2'-bipyridine;
两个发光的钌 (II) 多吡啶复合物附加了 D-果糖单元,[Ru(N^N)2(bpy-果糖)](PF6)2 (bpy-果糖 = 4-(1-脱氧-D-果糖- 1-yl)aminocarbonyl-4'-methyl-2,2'-bipyridine; N^N = 4,7-diphenyl-1,10-phenanthroline (Ph2-phen) (1a) 和 2,2'-bipyridine (bpy ) (2a)) 及其不含 D-果糖的对应物 [Ru(N^N)2(bpy-Et)](PF6)2 (bpy-Et = 4-乙基氨基羰基-4'-甲基-2,2'-联吡啶;N^N = Ph2-phen (1b) 和 bpy (2b)) 被合成和表征。研究了复合物的光物理特性、亲脂性、细胞毒性和细胞摄取。激光扫描共聚焦显微镜显示复合物 1a 和 1b 均显示出对人乳腺腺癌 (MCF-7) 细胞的强烈膜染色。然而,虽然复合物
