So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Wang, Rui; Ranganathan, Srivathsan V.; Haruehanroengra, Phensinee; Mao, Song; Scalabrin, Matteo; Fabris, Daniele; Chen, Alan; Liu, Hehua; Hassan, Abdalla E.

Keywords: DNA bipyridine complex metal ion binding; DNA material; DNA scaffold; click reaction; metallic DNA; propargyl-DNA. We’ll tell you more about this compound (cas:1762-34-1).
The facile construction of metal-DNA complexes using ‘Click’ reactions is reported here. A series of 2′-propargyl-modified DNA oligonucleotides were initially synthesized as structure scaffolds and were then modified through ‘Click’ reaction to incorporate a bipyridine ligand equipped with an azido group. These metal chelating ligands can be placed in the DNA context in site-specific fashion to provide versatile templates for binding various metal ions, which are exchangeable using a simple EDTA washing-and-filtration step. The constructed metal-DNA complexes were found to be thermally stable. Their structures were explored by solving a crystal structure of a propargyl-modified DNA duplex and installing the bipyridine ligands by mol. modeling and simulation. These metal-DNA complexes could have wide applications as novel organometallic catalysts, artificial RNases, and potential metal delivery systems.
