  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.

• (3 + 3) Cycloaddition of Oxyallyl Cations with Nitrones: Diastereoselective Access to 1,2-Oxazinanes
  作者：Marie Cordier、Alexis Archambeau

  日期：2018.4.20

  Oxyallyl cations are prepared in situ from readily available α-tosyloxy ketones and act as transient electrophilic partners in (3 + 3) cycloaddition with nitrones. Under mild conditions, this method provides a chemoselective and diastereoselective route to polysubstituted 1,2-oxazinanes. A stepwise process is proposed to rationalize the diastereoselectivity of this transformation.

  由容易获得的α-甲苯磺酰氧基原位制备羟基烯丙基阳离子，并在与硝酮的（3 + 3）环加成中充当瞬态亲电子伙伴。在温和的条件下，该方法为多取代的1,2-恶嗪酮提供了化学选择性和非对映选择性的途径。提出了逐步处理以合理化此变换的非对映选择性。
