It is an object of the present invention to provide an on-off type fluorescent compound used in gene analyses, which is highly stable and highly sensitive, and which enables amplification of a trace amount of gene signal and observation thereof. The present invention provides a compound represented by the following formula (1) or (2):
wherein R1 represents an alkyl group containing 1 to 6 carbon atoms, an amino group, an amide group optionally having a protecting group or a substituent, a halogen atom, or a hydrogen atom; R2 independently represents an alkyl group containing 1 to 6 carbon atoms, a halogen atom, or a hydrogen atom; R3 represents an alkyl group containing 1 to 6 carbon atoms, an aryl group, or a hydrogen atom; R4 represents a group containing an oxygen atom, or a hydrogen atom, wherein R3 may bind to R4 to form a ring.
本发明的目的是提供一种用于基因分析的开关型荧光化合物,它具有高稳定性和高灵敏度,能放大微量基因信号并对其进行观察。本发明提供了由下式(1)或(2)代表的化合物:
其中 R1 代表含有 1 至 6 个碳原子的烷基、氨基、可选择具有保护基团或取代基的酰胺基、卤素原子或氢原子;R2 独立地代表含有 1 至 6 个碳原子的烷基、卤素原子或氢原子;R3 代表含有 1 至 6 个碳原子的烷基、芳基或氢原子;R4 代表含有氧原子或氢原子的基团,其中 R3 可与 R4 结合形成环。
