We synthesized new DNA intercalators, polyol- or cyclic sugar-linked anthraquinone derivatives. The binding affinity of these DNA intercalators is suggested to be controlled by the configuration and steric structure of sugar chain with the cyclic sugar chain interacting more strongly than the open-chain polyol unit with double stranded DNA.
我们合成了新的 DNA 中间体--多元醇或环糖连接的
蒽醌衍
生物。这些 DNA 中间体的结合亲和力受糖链的构型和立体结构控制,环糖链比开链多元醇单元与双链 DNA 的相互作用更强。
