(57) [Summary] [Purpose] A novel and useful Cypridina luciferin that can be used as a substrate for sugar hydrolases such as α-D-galactosidase to emit light and can be used for quantification of sugar hydrolases. Obtain the derivative. [Structure] A Cypridina luciferin derivative represented by the following general formula (1). Embedded image (R 1 and R 2 are hydrogen, an alkyl group having 1 to 20 carbon atoms, An aryl group having 6 to 20 carbon atoms or an arylalkyl group having 7 to 19 carbon atoms. R 3 is an alkyl group or an alkoxy group having 1 to 5 carbon atoms. n is an integer of 0-5. ) |
