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—)。
