  Rational design of the first small-molecule antagonists of NHERF1/EBP50 PDZ domains

  摘要：

  This report describes the first small-molecule antagonists that specifically target the ligand-binding pocket of PDZ domains of NHERF1 multi-functional adaptor protein. Comparison of the peptide sequence homology between the native ligand of NHERF1 PDZ domains and an indole-based non-peptide chemical scaffold allowed the design of a small-molecule antagonist of NHERF1 PDZ domains.

  Mannich-isomerization reaction that allows the direct construction of 1,4-stereocenters in a highly stereoselective manner. This asymmetric transformation demonstrated the potential of a tandem nucleophilic addition-isomerization reaction as a broadly useful strategy for the efficient construction of 1,4-stereocenters. Notably, this tandem reaction was mediated by a single chiral betaine as a dual-functional

  包含不相邻立体中心的手性基序的构建是一项重大挑战，因为它们通常是使用不同的手性催化剂在不同的步骤中构建的。因此，开发简化此类复杂基序构造的新策略已成为不对称合成的主要焦点。我们在此报告了前所未有的不对称串联曼尼希异构化反应，该反应允许以高度立体选择性的方式直接构建 1,4-立体中心。这种不对称转化证明了串联亲核加成异构化反应作为有效构建 1,4-立体中心的广泛有用策略的潜力。值得注意的是，这种串联反应是由作为双功能催化剂的单一手性甜菜碱介导的，

  We designed and synthesized a series of indole-2-amide-based compounds that antagonize interaction between the Dishevelled (Dvl) PDZ domain and a peptide derived from the natural PDZ ligand Frizzled-7 (Fz7). These compounds inhibit Tcf-mediated transcription activated by exogenous Dvl via the biochemical antagonism. We confirmed tumor cell-selective activation of caspases by these compounds.

  The development of selective inhibitors for individual PLA(2) enzymes is necessary in order to target PLA(2)-specific signaling pathways, but it is challenging due to the observed promiscuity of known PLA(2) inhibitors. In the current work, we present the development and application of a variety of synthetic routes to produce pentafluoro, tetrafluoro, and trifluoro derivatives of activated carbonyl groups in order to screen for selective inhibitors and characterize the chemical properties that can lead to selective inhibition. Our results demonstrate that the pentafluoroethyl ketone functionality favors selective inhibition of the GVIA iPLA(2), a very important enzyme for which specific, potent, reversible inhibitors are needed. We find that 1,1,1,2,2-pentafluoro-7-phenyl-heptan-3-one (FKGK11) is a selective inhibitor of GVIA iPLA(2) (X-1(50) = 0.0073). Furthermore, we conclude that the introduction of an additional fluorine atom at the alpha' position of a trifluoromethyl ketone constitutes an important strategy for the development of new potent GVIA iPLA(2) inhibitors.
