Abstract: The synthesis of peptide-luciferin conjugates has a pivotal role in the development of bioluminescent detection systems that are based on the determination of protease enzyme activity. This work describes the optimized synthesis of an N-peptide-6-amino-d-luciferin conjugate (Fmoc-Gly-Pro-6-amino-d-luciferin) with a simple fragment condensation method in adequate yields. Fmoc-Gly-Pro-6-amino-d-luciferin was produced from a previously synthesized Fmoc-Gly-Pro-OH and also previously synthesized 6-amino-2-cyanobenzothiazole with an optimized method, to which conjugate cysteine was added in an also improved way. The resulting conjugate was successfully used in a bioluminescent system, in vitro, demonstrating the applicability of the method. Graphical Abstract: [Figure not available: see fulltext.].
