DNA-sequence-selective hairpin polyamide platinum(II) complexes, containing pyrrole and imidazole heterocyclic rings, have been synthesised by different methods. A six-ring complex, selective for (A/T)GGG(A/T) DNA sequences, was made by using solid-phase synthesis, whilst an eight-ring complex, selective for (A/T)CCTG(A/T) DNA sequences, was made by utilising standard wet chemistry. Solid-phase synthesis resulted
已通过不同方法合成了两种含有吡咯和咪唑杂环的DNA序列选择性发夹式聚酰胺铂(II)复合物。通过固相合成制备了对(A / T)GGG(A / T)DNA序列具有选择性的六环复合物,而对(A / T)CCTG(A / T)具有选择性的八环复合物DNA序列是通过使用标准的湿化学法制得的。固相合成比湿法合成具有更高的收率,更少的纯化且更有效。因此,这是进行进一步工作的首选方法。金属配合物通过(1)H和(195)Pt NMR光谱法和ESI质谱法表征。这两种化合物为合成包含多个发夹和/或铂基的更复杂分子提供了基础。
