Yvonne; Fish, Paul V. published an article on February 1 ,2020. The article was titled 《Scaffold-hopping identifies furano[2,3-d]pyrimidine amides as potent Notum inhibitors》, and you may find the article in Bioorganic & Medicinal Chemistry Letters.SDS of cas: 108831-66-9 The information in the text is summarized as follows:
The carboxylesterase Notum is a key neg. regulator of the Wnt signaling pathway by mediating the depalmitoleoylation of Wnt proteins. Our objective was to discover potent small mol. inhibitors of Notum suitable for exploring the regulation of Wnt signaling in the central nervous system. Scaffold-hopping from thienopyrimidine acids 1 and 2, supported by X-ray structure determination, identified 3-methylimidazolin-4-one amides 20-24 as potent inhibitors of Notum with activity across three orthogonal assay formats (biochem., extra-cellular, occupancy). A preferred example 24 demonstrated good stability in mouse microsomes and plasma, and cell permeability in the MDCK-MDR1 assay albeit with modest P-gp mediated efflux. Pharmacokinetic studies with 24 were performed in vivo in mouse with single oral administration of 24 showing good plasma exposure and reasonable CNS penetration. We propose that 24 is a new chem. tool suitable for cellular studies to explore the fundamental biol. of Notum. In the experiment, the researchers used many compounds, for example, 6-Methyl-3H-thieno[2,3-d]pyrimidin-4-one(cas: 108831-66-9SDS of cas: 108831-66-9)
6-Methyl-3H-thieno[2,3-d]pyrimidin-4-one(cas: 108831-66-9) belongs to pyrimidine. Pyrimidine nucleotide derivatives have a wide range of biological applications. For example, pyrimidine derivatives are useful in DNA repair studies involving cancer and epigenetics.SDS of cas: 108831-66-9
