  There has been a need for coelenteramide analogs or the like that produce fluorescent proteins which exhibit different fluorescent characteristics from those of the existing fluorescent proteins. Disclosed is a compound represented by general formula (1) (wherein R1 represents a substituted or unsubstituted aryl, a substituted or unsubstituted arylalkyl, a straight or branched alkyl which may optionally be substituted with an alicyclic group, an alicyclic group or a heterocyclic group; R2 represents hydrogen or —(SO2)R4; R3 represents hydrogen, hydroxyl, methoxy or acetoxy; R4 represents a substituted or unsubstituted aryl, a substituted or unsubstituted arylalkyl or a straight or branched alkyl which may optionally be substituted with an alicyclic group; and X1 represents —C(═S)— or —SO2—).

  有需要制备与coelenteramide类似的化合物或其他化合物，这些化合物能够产生不同于现有荧光蛋白的荧光特性。本发明揭示了一种化合物，其通式为（1）（其中，R1代表取代或未取代的芳基，取代或未取代的芳基烷基，可选地用含脂环基的直链或支链烷基取代的直链或支链烷基，脂环基或杂环基；R2代表氢或—（SO2）R4；R3代表氢，羟基，甲氧基或乙酰氧基；R4代表取代或未取代的芳基，取代或未取代的芳基烷基或可选地用含脂环基的直链或支链烷基取代的直链或支链烷基；X1代表—C（═S）—或—SO2—）。

  A fluorescent protein (bFP) having chemiluminescence activity is a complex composed of the apoprotein of a calcium-binding photoprotein, coelenteramid or an analog thereof, and calcium ions or divalent or trivalent ions that can be substituted for the calcium ions. In the complex, the ratio of the number of molecules of the apoprotein to that of the coelenteramid is 1:1 and the ratio of the number of molecules of the apoprotein to that of the divalent or trivalent ions is 1:1 to 1:4. The fluorescent protein is used as a marker because it catalyzes luminescence of coelenterazine and has fluorescence capability. Removal of calcium ions etc. from this fluorescent protein (bFP) having luminescence activity provides a novel fluorescent protein (gFP). Mixing this gFP with the coelenterazine provides a calcium-binding photoprotein, which emit light instantaneously, enabling use as a marker.
