Two new dicopper(II) complexes bridged by N-(2-hydroxy-5-methylphenyl)-N′-[3-(dimethyl-amino)propyl]oxamide (H3hmpoxd), and end-capped with 4,4′-dimethyl-2,2′-bipyridine (Me2bpy) and 2,2′-bipyridine (bpy), were synthesized and structurally characterized, namely [Cu2(hmpoxd)(CH3OH)(Me2bpy)](ClO4) (1) and [Cu2(hmpoxd)(bpy)](ClO4)∙CH3OH (2). The single-crystal X-ray diffraction analysis reveals that the
N-(2-羟基-5-甲基苯基)-N '-[3-(二甲基-氨基)丙基]乙酰胺(H 3 hmpoxd)桥接的两个新的双铜(II)配合物,并用4,4'封端合成了2-二甲基-2,2'-联吡啶(Me 2 bpy)和2,2'-联吡啶(bpy),并进行了结构表征,即[Cu 2(hmpoxd)(CH 3 OH)(Me 2 bpy)]( ClO 4)(1)和[Cu 2(hmpoxd)(bpy)](ClO 4)·CH 3 OH(2)。X射线单晶衍射分析表明,内,外铜离子被顺式-hmpoxd 3-配体分别位于1和2的方形平面和方形金字塔形几何体中。DNA /蛋白质结合的性质已在理论和实验上进行了研究,表明这两种复合物都可以以嵌入的方式与DNA相互作用,并通过1的Trp213和Trp134的有利结合位点有效地淬灭了BSA蛋白质的固有荧光。2。体外抗癌活性显示这两种复合物对所选的肿瘤细胞系具有活性,并且抗癌活性与其DNA
