  Discovery and hit-to-lead optimization of novel allosteric glucokinase activators

  摘要：

  We report on a hit generation and hit-to-lead program of a novel class of glucokinase activators (GKAs). Hit compounds, activators at low glucose concentration only were identified by vHTS. Scaffold modification reliably afforded activators also at high substrate level. Potency was increased by introduction of a hydrogen bond acceptor as proposed by molecular docking. Replacement of the initial alkylene linkers with a rigid 1,2-phenylene motif followed by further studies eventually furnished a series of potent lead compounds exhibiting steep SAR.

  The invention is directed to novel bis-quarternary cinchona alkaloid salts and the use of bis-quarternary cinchona alkaloid salts in asymmetric phase transfer catalysis. The present invention is directed to novel bis-quarternary cinchona alkaloid salts and the use of bis-quartenary cinchona alkaloid salts in asymmetric phase transfer catalysis. On certain substrates and under specific reaction conditions, the inventors have discovered that the use of bis-quarternary cinchona alkaloid salts in asymmetric phase transfer catalysis surprisingly provides for a more active and efficient process as compared to mono-quarternary catalysts.
