Provided herein are analogs of unnatural nucleotides bearing predominantly hydrophobic nucleobase analogs that form unnatural base pairs during DNA polymerase- mediated replication of DNA or RNA polymerase-mediated transcription of RNA. In this manner, the unnatural nucleobases can be introduced in a site-specific way into oligonucleotides (single or double stranded DNA or RNA), where they can provide for site-specific cleavage, or can provide a reactive linker than can undergo functionalization with a cargo -bearing reagent by means of reaction with a primary amino group or by means of click chemistry with an alkyne group of the unnatural nucleobase linker.
本文提供了一些不自然核苷酸的类似物,主要带有疏水性核碱基类似物,这些类似物在DNA聚合酶介导的DNA复制或RNA聚合酶介导的RNA转录过程中形成不自然碱基对。通过这种方式,可以将这些不自然碱基以特定位置的方式引入寡核苷酸(单链或双链DNA或RNA)中,从而可以实现特定位置的切割,或者可以提供一个反应性连接物,通过与主要氨基团反应或与不自然碱基连接物的炔基团进行点击化学反应,从而实现与携带试剂的载体的官能化。
