Abstract

Bioluminescent imaging (BLI) technology has been extensively applied due to various advantages such as noninvasiveness, high sensitivity and selectivity, excellent biocompatibility and real-time visualization and monitoring. The firefly luciferase (Fluc)/luciferin system, one of the principal bioluminescent systems, has been developed as a sensor for imaging biological processes. However, a limited number of Fluc substrates hamper the further application of firefly luciferase/luciferin systems for biomedical purposes. Here we describe an approach to synthesize a series of novel luciferin substrates (cyaLucs) that produced elevated bioluminescent signals in vitro. Furthermore, we demonstrate the high efficiency of N-cyclobutylaminoluciferin (cybLuc) with high light emission and long duration in deep tissue imaging by diagnosis of cerebral tumors in vivo in a rodent model.
