  Design and application of a rigid quinazolone scaffold based on two-face Bim α-helix mimicking

  摘要：

  Based on our previous discovery of an anthraquinone scaffold mimicking two faces of Bim a-helix, we derived a quinazolone scaffold through structure simplification and optimization. It was inferred that a rigid bicyclic ring was necessary and efficient to maintain the two-faced binding mode. A novel dual inhibitor 6c [6,7,8-trihydroxy-3-(2-hydroxy-5-methylbenzyl)-2-phenylquinazolin-4(3H)-one] was obtained based on this scaffold. 6c exhibited dual binding activity with Ki values of 0.123 mu M for Mcl-1 and 0.179 mu M for Bcl-2.

  9-bis(phenyldiazo)-1,10-phenanthroline (L2) ligands produced two new mononuclear five-coordinate cobalt(II)-complexes 1b and 2 respectively. In complex 1a and 1b, the ligands L1a and L1b are coordinated to the cobalt(II)-center in a tridentate mode utilizing all of its nitrogen donor sites while in complex 2 one of the azo-donor sites of the ligand L2 remain pendant. All these complexes were characterized using available

  Tankyrases (TNKSs), members of the PARP (Poly(ADP-ribose)polymerases) superfamily of enzymes, have gained interest as therapeutic drug targets, especially as they are involved in the regulation of Wnt signalling. A series of 2-arylquinazolin-4-ones with varying substituents at the 8-position was synthesised. An 8-methyl group (compared to 8-H, 8-OMe, 8-OH), together with a 4′-hydrophobic or electron-withdrawing

  Tankyrases (TNKSs) 是 PARP（聚（ADP-核糖）聚合酶）酶超家族的成员，作为治疗药物靶点引起了人们的兴趣，特别是因为它们参与 Wnt 信号传导的调节。合成了一系列在 8 位具有不同取代基的 2-芳基喹唑啉-4-酮。8-甲基（与 8-H、8-OMe、8-OH 相比）与 4'-疏水或吸电子基团一起对 TNKS 提供了最大的效力和选择性。所选化合物与 TNKS-2 的共晶结构表明，与 PARP-1/2 相比，TNKS-2 中 8 位附近的蛋白质更具疏水性，从而使选择性合理化。NAD +-结合位点包含容纳 2-芳基的疏水腔；在 TNKS-2 中，它有一条通往外部的隧道，但在 PARP-1 中空腔是封闭的。8-Methyl-2-(4-trifluoromethylphenyl)quinazolin-4-one 被确定为 TNKSs 和 Wnt 信号传导的有效和选择性抑制剂。这种
