the synthesis of a 5′-boronoribonucleotidic phosphoramidite building block, its incorporation at the 5′ extremities of RNA sequences, and its ability to generate boronate internucleosidic linkages by RNA- and DNA-templated ligation. Moreover, melting denaturation studies also revealed that 5′-boronic acid ended RNA sequences are able to promote the formation of RNA loops in the presence of RNA templating
能够控制超分子生物聚合物组装和拆卸的模板的使用是一种有吸引力的方法,其应用范围从设计新的生物聚合物到调节复杂的生物系统。因此,基于自组装核酸的系统具有构建定义明确且刺激响应的分子结构的实质潜力。我们在这里首次报告5'-硼核糖核苷酸亚磷酰胺构件的合成,在5'末端的RNA序列的掺入以及通过RNA和DNA模板连接产生硼酸核苷间键的能力。此外,熔融变性研究还表明,在存在RNA模板伴侣的情况下,5'-硼酸末端的RNA序列能够促进RNA环的形成。
