It is an object of the present invention to provide quenching or fluorescent nucleic acid base analogs and applications thereof. The quencher of the present invention has a 2-nitropyrrole structure represented by Formula I:
(in Formula I, R1 and R2 are groups independently selected from the group consisting of:
ribose and deoxyribose;
hydrogen, hydroxyl and SH groups, and halogens;
substituted or unsubstituted alkyl, alkenyl, and alkynyl groups each having 2 to 10 carbon atoms;
one or more five-membered heterocyclic rings, one or more six-membered heterocyclic rings, and one or more fused heterocyclic rings, these heterocylic rings containing nitrogen or sulfur, and one or more aromatic rings;
sugars, sugar chains, amino acids, and peptides; and
fluorescent molecules linked via linkers).
本发明的目的是提供淬灭或荧光核酸碱类似物及其应用。本发明的淬灭剂具有由式 I 表示的 2-硝基吡咯结构:
(式 I 中,R1 和 R2 是独立选自以下组别的基团:
核糖和脱氧核糖;
氢、羟基、SH 基和卤素;
各自具有 2 至 10 个碳原子的取代或未取代的烷基、烯基和炔基;
一个或多个五元杂环、一个或多个六元杂环、一个或多个融合杂环(这些杂环含有氮或硫)以及一个或多个芳香环;
糖、糖链、氨基酸和肽;以及
通过连接体连接的荧光分子)。
