Hoechst 33258 1 的新类似物具有较小的结构变化,即酚基 OH 基团位于间位而不是对位,通过足迹、DNA 熔解研究和高场 1H NMR 光谱显示,其以与 Hoechst 33258 非常相似的方式结合到 DNA 的 AATT 序列,尽管 1H NMR 光谱分析表明配体的酚端可能被撬离小沟(相对于 Hoechst 33258)。 Hoechst 33258,并且 d(CGCGAATTCGCG)2 的主沟结构受到该 Hoechst 33258 类似物的结合的显着干扰。
A new analogue of Hoechst 33258 1 with a small structural change, i.e., the phenolic OH group being located meta rather than para, has been shown by footprinting, DNA melting studies and high-field 1H NMR spectroscopy to bind to the AATT sequences of DNA in a manner grossly similar to Hoechst 33258, although analysis by 1H NMR spectroscopy indicates that the phenolic end of the ligand could be prised away from the minor groove relative to Hoechst 33258, and that the major groove structure of d(CGCGAATTCGCG)2 is significantly perturbed by the binding of this Hoechst 33258 analogue.
