assay. The results of these studies show the presence of several platinum species in solution. Based on the column retention properties of the species as well as their behavior to changes in pH, it is concluded that these solution components are various monomers and oligomers of the parent platinum complex. These results are in agreement with previous 195 Pt and 15 N NMR studies from other diamineplatinum(II)
摘要具有硫酸根或新型磺基丙酸根阴离子离去基团的水溶性(1,2-二芳基-1,2-乙二胺)铂(II)配合物的合成,固态和溶液化学以及体外细胞毒性活性,被描述。通过使(1,2-二芳基-1,2-乙二胺)二碘铂(II)络合物与硫酸银或磺基丙酸银在水中反应来制备化合物。固态络合物的IR研究表明,这些制剂是铂类物质的混合物,其中阴离子离去基团显示出各种形式的铂配位。这些组成根据用于分离铂络合物的方法而变化。通过反相HPLC测定研究水溶液的化学性质。这些研究的结果表明溶液中存在几种铂。根据物质的柱保留特性及其对pH值变化的行为,可以得出结论,这些溶液组分是母体铂配合物的各种单体和低聚物。这些结果与先前从其他二胺铂(II)配合物中进行的195 Pt和15 N NMR研究一致。芳族取代的类型对水性铂族物质的定性组成有影响。与具有对氟基团的配合物相比,在具有邻苯酚基团的铂配合物的水溶液中观察到另外的铂物质。铂络
