calculations. A very good agreement between experiment and theory was obtained, with a standard deviation of 0.13 V. It was shown that theoretical calculations can be of a limited predictive power for new RuII complexes, though it was difficult to reproduce differences smaller than 0.05 V. Several compounds of this series exhibited a considerable cytostatic effect and activity against the hepatitis C
制备了一系列乙炔基-或(4-硼苯基)联吡啶和-菲咯啉作为通用结构单元,用于通过交叉偶联反应将双齿 N-配体连接到其他分子。它们与 Ru(bpy)2Cl2 的络合得到相应的 RuII 络合物。通过乙炔基-或4-硼基苯基联吡啶和-菲咯啉与9-苄基-8-溴腺嘌呤的交叉偶联反应制备通过共轭乙炔或亚苯基连接基连接的在8位带有联吡啶或菲咯啉复合物的9-苄基腺嘌呤衍生物。它们与 Ru(bpy)2Cl2 的络合提供了相应的 Ru 络合物作为电化学 DNA 标记的模型化合物。同样的化合物也可以通过 9-苄基-8-溴腺嘌呤与炔烃和硼酸的 Ru 络合物的交叉偶联直接制备。两种方法在核酸标记的潜在应用方面进行了比较。通过 X 射线衍射确定了两种 Ru 配合物的晶体结构。用碳糊和汞电极通过循环或方波伏安法研究了带有菲咯啉或联吡啶配体和 Ru 配合物的模型嘌呤的电化学。将标题化合物的实验氧化还原电位与量子化学计算进行
