In this study, a new firefly luciferin analog that can switch firefly bioluminescence (BL) activity from ‘off’ to ‘on’ state was designed and synthesized. BL inactive N-Ac-γ-glutamate luciferin 3 contains an acyclic precursor of the thiazoline moiety. Enzymatic treatment of 3 with aminoacylase resulted in a smooth removal of the acyl protecting group and concomitant cyclization to provide BL active carboluciferin 2.
