So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic.Mallinger, Aurelie; Crumpler, Simon; Pichowicz, Mark; Waalboer, Dennis; Stubbs, Mark; Adeniji-Popoola, Olajumoke; Wood, Bozena; Smith, Elizabeth; Thai, Ching; Henley, Alan T.; Georgi, Katrin; Court, William; Hobbs, Steve; Box, Gary; Ortiz-Ruiz, Maria-Jesus; Valenti, Melanie; De Haven Brandon, Alexis; Te Poele, Robert; Leuthner, Birgitta; Workman, Paul; Aherne, Wynne; Poeschke, Oliver; Dale, Trevor; Wienke, Dirk; Esdar, Christina; Rohdich, Felix; Raynaud, Florence; Clarke, Paul A.; Eccles, Suzanne A.; Stieber, Frank; Schiemann, Kai; Blagg, Julian researched the compound: tert-Butyl 4-(dimethylcarbamoyl)piperidine-1-carboxylate( cas:254905-58-3 ).Product Details of 254905-58-3.They published the article 《Discovery of Potent, Orally Bioavailable, Small-Molecule Inhibitors of WNT Signaling from a Cell-Based Pathway Screen》 about this compound( cas:254905-58-3 ) in Journal of Medicinal Chemistry. Keywords: trisubstituted pyridine preparation bioavailability WNT signaling inhibitor antitumor. We’ll tell you more about this compound (cas:254905-58-3).
WNT signaling is frequently deregulated in malignancy, particularly in colon cancer, and plays a key role in the generation and maintenance of cancer stem cells. The authors report the discovery and optimization of a 3,4,5-trisubstituted pyridine, 1-(3,5-Dichloropyridin-4-yl)piperidine-4-carboxamide (9), using a high-throughput cell-based reporter assay of WNT pathway activity. The authors demonstrate a twisted conformation about the pyridine-piperidine bond of (9) by small-mol. x-ray crystallog. Medicinal chem. optimization to maintain this twisted conformation, cognisant of physicochem. properties likely to maintain good cell permeability, led to 8-[3-Chloro-5-[4-(1-methyl-1H-pyrazol-4-yl)phenyl]pyridin-4-yl]-2,8-diazaspiro[4,5]decan-1-one (74) (CCT251545), a potent small-mol. inhibitor of WNT signaling with good oral pharmacokinetics. The authors demonstrate inhibition of WNT pathway activity in a solid human tumor xenograft model with evidence for tumor growth inhibition following oral dosing. This work provides a successful example of hypothesis-driven medicinal chem. optimization from a singleton hit against a cell-based pathway assay without knowledge of the biochem. target.
