The Firefly luciferase assay is commonly used as a transcriptional reporter due to its sensitivity to changes in reporter transcription and short half-life. However, compounds that resemble FLuc substrates can act as competitive inhibitors of the enzyme, leading to an increase in luminescence signal and difficulty in distinguishing active compounds against the target from those active against FLuc. A biochemical assay was used to screen the MLSMR library for FLuc activity to identify compounds that are FLuc inhibitors. Is the molecule effective to this assay?
