An RNA of the present invention is an RNA containing a 5′ cap structure and a coding region having a 5′ initiation codon and a 3′ stop codon on both ends of the coding region, the RNA having a nucleoside compound introduced at a site selected from among the 5′ cap structure and 10 bases from a 5′ end of the RNA, wherein the nucleoside compound is such that a group is attached to (i) a carbon atom at position 8 of a purine nucleus or (ii) a carbon atom at position 5 or 6 of a pyrimidine nucleus, the group being represented by formula (I):
A-X═X-# (I)
where A represents an aryl group or a heteroaryl group, # represents a site where the group represented by the formula (I) is attached to the carbon atom at the position 8 of the purine nucleus or the carbon atom at the position 5 or 6 of the pyrimidine nucleus, and two Xs, which are identical to or different from each other, each represents a nitrogen atom or CH whose H may be substituted by alkyl.
本发明的RNA是一种包含5'帽结构和编码区域的RNA,该编码区域的两端具有5'起始密码子和3'终止密码子,该RNA在从5'端选定的位置引入了一个核苷化合物,其中该核苷化合物是这样的,一个基团连接到(i)嘌呤核的第8位碳原子或(ii)嘧啶核的第5位或第6位碳原子,该基团由式(I)表示:A-X═X-#(I),其中A代表芳基或杂环基,#代表基团所连接到的嘌呤核的第8位碳原子或嘧啶核的第5位或第6位碳原子的位置,两个X,它们相同或不同,每个代表氮原子或其氢可能被烷基取代的CH。
