A Putative Frizzled 7-Targeting Compound Acts as a Firefly Luciferase Inhibitor.

ABSTRACT: The Frizzled family (FZD_1-10) of G protein-coupled receptors regulates WNT signaling mediating proliferative input. Dysregulation of FZD₇ and exaggerated WNT/β-catenin signaling is frequently observed in intestinal cancers. Therefore, it is attractive to develop therapeutics targeting FZD₇ for cancer treatment. Structure-based virtual screening has identified compound 28, which inhibited WNT/β-catenin signaling based on the luciferase-based reporter gene TOPFlash assay. However, upon pharmacological validation, compound 28 rather acts as a potent Firefly luciferase (Fluc) inhibitor (IC₅₀ = 30 nM), matching the reported IC₅₀ for compound 28-mediated inhibition in the TOPFlash assay. Moreover, we employed Fluc-independent assays, a FZD
