[graph: see text] We describe the synthesis of new environmentally sensitive fluorescence probes to elucidate DNA structures. DNA oligonucleotides containing fluorophore dan (6-(dimethylamino)-2-acylnaphthalene)-modified dC or dG were able to monitor the microenvironmental changes in both the major and minor grooves of DNA with a B- to A-DNA conformational transition and RNA hybridization.
[图表:见正文] 我们描述了用于阐明DNA结构的新型环境敏感荧光探针的合成。含有荧光团dan(6-(二甲基氨基)-2-酰基萘)修饰的dC或dG的DNA寡核苷酸能够监测DNA从B型到A型构象转变以及RNA杂交过程中主沟和副沟的微环境变化。
