Displacement reactions of 2-chloro- and 2,9-dichloro-1,10-phenanthroline: synthesis of a sulfur-bridged bis-1,10-phenanthroline macrocycle and a 2,2′-amino-substituted-bis-1,10-phenanthroline
摘要:
The synthesis and structural assignments of 9-chloro-1,1-phenanthroline-2(1H)-thione and 1,10-dihydro-1,10-phenanthroline-2,9-dithione have been accomplished. The sulfur-bridged bis-1,10-phenanthroline macrocycle was readily prepared by heating the thione or equimolar amounts of the dithione and 2,9-dichloro-1,10-phenanthroline in diphenyl ether. Displacements of 2-chloro- or 2,9-dichloro-1,10-phenanthroline with N,N-dimethylethylenediamine afforded the corresponding airline and diamino analogues. Am amino-substituted-2,2'-bis-1,10-phenanthroline has been prepared. (C) 2009 Elsevier Ltd. All rights reserved.

Synthesis of a New Copper Complex of a Macrocyclic Compound Consisting of 1,10-Phenanthroline, and Its DNA Binding and Cleaving Activity
interaction of [Cu(smc)] with DNA was examined by UV-vis absorption spectroscopy, circular dichroism spectroscopy, and viscometry. The binding constant of [CuI(smc)] with DNA is 4.2 × 104 M−1, which is almost identical with that of bis(1,10-phenanthroline)copper, [CuI(phen)2]. A viscosity measurement indicates that [CuI(smc)] binds to DNA by an intercalative mode. [Cu(smc)] cleavesDNA in the presence of a
合成了由两个硫原子 [Cu(smc)] 桥接的两个 1,10-菲咯啉分子组成的大环化合物的铜配合物。[Cu(smc)] 与 DNA 的相互作用通过 UV-vis 吸收光谱、圆二色光谱和粘度测定法进行了检查。[CuI(smc)]与DNA的结合常数为4.2 × 104 M-1,与双(1,10-菲咯啉)铜[CuI(phen)2]的结合常数几乎相同。粘度测量表明 [CuI(smc)] 通过嵌入模式与 DNA 结合。[Cu(smc)] 在有氧条件下,在还原剂存在的情况下切割 DNA。在这个过程中·OH起着重要的作用。
