Synthesis of a novel suppressor of beta-cell apoptosis via diversity-oriented synthesis
The synthesis of a stereochemically diverse library of medium-sized rings accessible via a “build/couple/pair” strategy is described. Key aspects of the synthesis include SNAr cycloetherification of a linear amine template to afford eight stereoisomeric eight-membered lactams and subsequent solid-phase diversification of these scaffolds to yield a 6488-membered library. Screening of this compound collection in a cell-based assay for the suppression of cytokine-induced beta-cell apoptosis resulted in the identification of a small-molecule suppressor capable of restoring glucose-stimulated insulin secretion in a rat beta-cell line. The presence of all stereoisomers in the screening collection enabled preliminary determination of the structural and stereochemical requirements for cellular activity, while efficient follow-up chemistry afforded BRD0476 (probe ML187), which had an approximately 3-fold increase in activity. These results demonstrate the utility of diversity-oriented synthesis to probe discovery using cell-based screening and the importance of including stereochemical diversity in screening collections for the development of stereo/structure-activity relationships.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.Application In Synthesis of Tetrahydro-2H-pyran-4-carbonyl chloride, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 40191-32-0, in my other articles.
