J.Med.Chem., 63:12942-12956, 2020 Cited by PubMed Abstract: Carboxylesterase Notum is a negative regulator of the Wnt signaling pathway. There is an emerging understanding of the role Notum plays in disease, supporting the need to discover new small-molecule inhibitors. A crystallographic X-ray fragment screen was performed, which identified fragment hit 1,2,3-triazole as an attractive starting point for a structure-based drug design hit-to-lead program. Optimization of identified oxadiazol-2-one as a preferred example with properties consistent with drug-like chemical space. Screening in a cell-based TCF/LEF reporter gene assay restored the activation of Wnt signaling in the presence of Notum. Mouse pharmacokinetic studies with oral administration of demonstrated good plasma exposure and partial blood-brain barrier penetration. Significant progress was made in developing fragment hit into lead (>600-fold increase in activity), making it suitable as a new chemical tool for exploring the role of Notum-mediated regulation of Wnt signaling.
