Small molecule fluorescent probes for established drug targets such as nucleic acids including DNA and RNA has been developed and disclosed herein. These nucleic acid probes bind to multiple DNA and RNA structures, and to sites crucial for nucleic acid function, such as DNA and RNA major grooves. Displacement of the probes by other binders such as small molecule compounds and/or proteins illicits a fluorescence change in the probe that once detected and analyzed provide binding information of these other binders of interest. Similarly, changes in fluorescence upon binding of the probes to nucleic acid have been applied to screen nucleic acid of different sequence and conformation. The nucleic acid probes and method of uses disclosed herein are advantageously suitable for high-through put screening of libraries of small molecule compounds, proteins, and nucleic acids.
本文开发并公开了针对核酸(包括 DNA 和 RNA)等既定药物靶点的小分子荧光探针。这些核酸探针与多种 DNA 和 RNA 结构以及对核酸功能至关重要的位点(如 DNA 和 RNA 主要沟槽)结合。探针被其他结合剂(如小分子化合物和/或蛋白质)置换后,探针的荧光会发生变化,这种变化一旦被检测和分析,就会提供这些其他相关结合剂的结合信息。同样,探针与核酸结合后的荧光变化也可用于筛选不同序列和构象的核酸。本文公开的核酸探针和使用方法非常适用于小分子化合物、蛋白质和核酸文库的高通量筛选。

with receptor 1 more strongly in the presence of sodium cations, whereas in the presence of potassium or ammonium cation the anion binding strength was greatly diminished. A homotopic anion receptor 3, lacking a crownether unit, was unable to bind sodium salt more strongly than tetrabutylammonium salts. Solution and solid-state X-ray measurements revealed that strong sodium coordination with the cation-binding
