  Synthesis of a Novel Suppressor of β-Cell Apoptosis via Diversity-Oriented Synthesis

  摘要：

  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.

  Profiling of eight stereoisomeric T. cruzi growth inhibitors revealed vastly different in vitro properties such as solubility, lipophilicity, pK(a), and cell permeability for two sets of four stereoisomers. Using computational chemistry and NMR spectroscopy, we identified the formation of an intramolecular NH -> NR3 hydrogen bond in the set of stereoisomers displaying lower solubility, higher lipophilicity, and higher cell permeability. The intramolecular hydrogen bond resulted in a significant pKa difference that accounts for the other structure property relationships. Application of this knowledge could be of particular value to maintain the delicate balance of size, solubility, and lipophilicity required for cell penetration and oral administration for chemical probes or therapeutics with properties at, or beyond, Lipinski's rule of 5.
