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:
[Formula 1]
(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基类似物及其应用。本发明的淬灭剂具有由式I表示的2-硝基吡咯结构:[Formula 1](在式I中,R1和R2是从以下组成的组中独立选择的基团:核糖和去氧核糖;氢、羟基和SH基团、卤素;取代或未取代的具有2到10个碳原子的烷基、烯基和炔基基团;一个或多个含氮或硫的五元杂环环、一个或多个含氮或硫的六元杂环环以及一个或多个融合的杂环环;糖、糖链、氨基酸和肽;以及通过连接物连接的荧光分子)。
