The BL spectra of the CTZ analogues 1a–d, 2a–d, and 3a–d according to marine luciferases. (A) The BL spectra of 1-series CTZ analogues with RLuc8.6–535. Inset a shows the optical image of BL. (B) The BL spectra of 1d according to various RLuc derivatives. (C) The BL spectra of 1-series CTZ analogues with ALuc16. Inset b shows the optical image of BL. (D) The BL spectra of 2- and 3-series CTZ analogues with ALuc16. (E) The BL spectra of 3a and 3d with NanoLuc. Abbreviations: CTZ, native coelenterazine; FWHM, full width half maximum; BL, bioluminescence.
