A new series of complexes of the type cis-PtL2X2 [where L is a monodentate AQ-Y(CH2)nNH2 and L2 is a bidentate AQ-Y(CH2)nNH(CH2)2NH2; AQ = anthraquinone, X = Cl, I, Y = NH, O] in which anthraquinone intercalators are tethered to the cis-PtCl2 unit via an (aminoalkyl)amino, (oxyalkyl)amino, or polyethylene glycol (aminoethyl)amino linker chains was prepared and screened in vitro against P388 leukemia
一系列新的顺式-PtL2X2型配合物[其中L是单齿AQ-Y(CH2)nNH2,L2是双齿AQ-Y(CH2)nNH(CH2)2NH2;AQ =蒽醌,X = Cl,I,Y = NH,O],其中蒽醌嵌入剂通过(氨基烷基)氨基,(氧基烷基)氨基或聚乙二醇(氨基乙基)氨基连接链束缚在顺式PtCl2单元上制备并体外筛选抗P388白血病。对选定的复合物进行了体内毒性研究。通过元素分析,195Pt NMR光谱和FTIR对所有配合物进行表征。1:1 Pt-嵌入剂复合物显示出比1:2 Pt-嵌入剂复合物更高的体外细胞毒性活性。二氯化物配合物始终比二碘化物对应物更具活性。在1:具有较短连接链(n = 2、3)的1 Pt-嵌入剂复合物表现出最高的细胞毒活性。三种化合物,[[[2-[[2-(蒽醌-1-基氨基)乙基]氨基]乙基]胺-N,N']二氯铂(II),[[2-[[3-(蒽醌-1-基氨基) )丙基]氨基]乙基]胺
