• Ru ^II and Ir ^III Complexes Containing ADA and DAD Triple Hydrogen Bonding Motifs: Potential Tectons for the Assembly of Functional Materials
  作者：Aidan P. McKay、Joseph I. Mapley、Keith C. Gordon、David A. McMorran

  DOI：10.1002/asia.201801748

  日期：2019.4.15

  characterisation of a series of [RuII(bpy)2L] and [Ir(ppy)2L] complexes containing ligands L with the potential to engage in triple hydrogen bonding interactions is described. L1 and L2 comprise pyridyl triazole chelating units with pendant diaminotriazine units, capable of donor‐acceptor‐donor (DAD) hydrogen bonding, while L3 and L4 contain ADA hydrogen bonding units proximal to N^N and N^O cleating sites, respectively

  描述了一系列含有配体L的[Ru II（bpy）2 L]和[Ir（ppy）2 L]配合物的合成和表征，该配合物具有参与三氢键合作用的潜力。L1和L2包含带有二氨基三嗪侧链的吡啶基三唑螯合单元，能够进行供体-受体-供体（DAD）氢键，而L3和L4分别包含靠近N ^ N和N ^ O裂解位点的ADA氢键单元。X射线晶体学分析显示含有Ru II配合物的L1和L2可通过氢键二聚体，而[Ru II（bpy）2 L 4 ]通过扩展的氢键基序组装形成一维链。相比之下，对于L3的Ru II和Ir III配合物，未观察到预期的氢键模式。光谱研究表明，配合物的吸收光谱是由MLCT和LLCT跃迁的组合产生的。Ir III和Ru II配合物的L1和L2配合物在固态发光，似乎氢键合到互补物质上可能会促进其3的调谐ILCT排放。低频拉曼光谱为L4配合物在固态中有序相互作用提供了进一步的证据，这与X射线晶体学的结果一致。

• A novel series of metabotropic glutamate receptor 5 negative allosteric modulators based on a 4,5,6,7-tetrahydropyrazolo[1,5-a]pyridine core

  A series of potent non-acetylinic negative allosteric modulators of the metabotropic glutamate receptor 5 (mGlu5 NAMs) was developed starting from HTS screening hit 1. Potency was improved via iterative SAR, and physicochemical properties were optimized to deliver orally bioavailable compounds acceptable for in vivo testing. A lead molecule from the series demonstrated dose-dependent activity in the second phase of the rat formalin test from 30 mg/kg, and a preliminary PK/PD relationship was established.

• Synthesis, DNA binding, fluorescence measurements and antiparasitic activity of DAPI related diamidines

  A novel series of extended DAPI analogues were prepared by insertion of either a carbon-carbon triple bond (16a-d) or a phenyl group (21a, b and 24) at position-2. The new amidines were evaluated in vitro against both Trypanosoma brucei rhodesiense (T. b. r.) and Plasmodium falciparum (P. f.). Five compounds (16a, 16b, 16d, 21a, 21b) exhibited IC50 values against T. b. r. of 9 nM or less which is two to nine folds more effective than DAPI. The same five compounds exhibited IC50 values against P. f. of 5.9 nM or less which is comparable to that of DAPI. The fluorescence properties of these new molecules were recorded, however; they do not offer any advantage over those of DAPI. (C) 2009 Elsevier Ltd. All rights reserved.
