The present invention provides, for example, a labeling substance that allows the double helix structure of a nucleic acid to be detected effectively. The present invention provides a compound having a structure derived from mononucleoside or mononucleotide, with the structure being represented by the following formula (1), (1b), or (1c), a tautomer or stereoisomer thereof, or a salt thereof.
In the above formulae, B is an atomic group having a nucleobase skeleton, E is an atomic group having a deoxyribose skeleton, a ribose skeleton, or a structure derived from either one of them, or an atomic group having a peptide structure or a peptoid structure, and Z11 and Z12 each are a hydrogen atom, a protecting group, or an atomic group that exhibits fluorescence and may be identical to or different from each other.
本发明提供了一种标记物质,例如,允许有效检测核酸的双螺旋结构。本发明提供了一种化合物,其结构源自单核苷酸或单核苷酸,该结构由以下公式(1),(1b)或(1c)表示,或其互变异构体或立体异构体,或其盐。在上述公式中,B是具有核碱基骨架的原子基团,E是具有脱氧核糖骨架,核糖骨架或源自其中任何一种的结构的原子基团,或具有肽结构或肽骨架的原子基团,Z11和Z12分别是氢原子,保护基或表现出荧光并且可以相同或不同的原子基团。
