破坏核酸结构的可光性核苷酸是有用的机制探针,可作为调节生化过程的工具。以前的探针可能受到需要将多个修饰的核苷酸合并到寡核苷酸中的限制,并且在动力学研究中通过转换为天然核苷酸的限速步骤。芳基硫化物1的光解产生高产量的5-甲基尿嘧啶,产物形成在不到一微秒内完成。芳基硫化物1阻止RNA发夹形成和preQ1类I核糖开关的完全折叠。在350 nm光解时,每个实例都实现了适当的折叠。芳基硫醚是一种新的调节RNA结构的工具,在自由基笼中形成5-甲基尿嘧啶,这表明它在动力学研究中是有用的。
Photolabile nucleotides that disrupt nucleic acid structure are useful mechanistic probes and can be used as tools for regulating biochemical processes. Previous probes can be limited by the need to incorporate multiple modified nucleotides into oligonucleotides and in kinetic studies by the rate-limiting step in the conversion to the native nucleotide. Photolysis of aryl sulfide 1 produces high yields of 5-methyluridine and product formation is complete in less than a microsecond. Aryl sulfide 1 prevents RNA hairpin formation and complete folding of the preQ1 class I riboswitch. Proper folding is achieved in each instance upon photolysis at 350 nm. Aryl sulfide 1 is a novel tool for modulating RNA structure and formation of 5-methyluridine within a radical cage suggests that it will be useful in kinetic studies.
