Coelenterazine analogs with different luminescence properties from conventional ones and coelenteramide analogs with different fluorescence properties from conventional ones have been desired. The invention provides coelenterazine analogs modified at the 8-position of coelenterazine and coelenteramide analogs modified at the 2- or 3-position of coelenteramide.
