  抑制癌症相关突变异柠檬酸脱氢酶：合成、结构-活性关系和选择性抗肿瘤活性

  摘要：

  异柠檬酸脱氢酶 1 (IDH1) 的突变常见于某些癌症，例如神经胶质瘤。与野生型 (WT) IDH1 不同，突变酶催化 α-酮戊二酸还原为d -2-羟基戊二酸 (D2HG)，从而引发癌症。几种 1-hydroxypyridin-2-one 化合物被鉴定为 IDH1(R132H) 的抑制剂。共合成了 61 种衍生物，并研究了它们的构效关系。用K i鉴定了有效的 IDH1(R132H) 抑制剂值低至 140 nM，而它们对 WT IDH1 具有弱活性或无活性。发现所选化合物对 IDH1(R132C) 的活性与其对 IDH1(R132H) 的抑制活性以及 D2HG 的细胞产生相关，R 2分别为 0.83 和 0.73。在基于细胞的模型测定中发现几种抑制剂可渗透血脑屏障，并对具有IDH1 R132H 突变的神经胶质瘤细胞表现出有效的选择性活性（EC 50 = 0.26–1.8 μM）。

  Click chemistry has been utilized to access 2,6-bis(1-aryl-1,2,3-triazol-4-yl)pyridines (BTPs) as versatile extended heteroaromatic building blocks for their exploitation in supramolecular chemistry, in particular foldamer and ligand design. In addition to their high-yielding synthesis using Cu(I)-catalyzed Huisgen-type 1,3-dipolar cycloaddition reactions the formed triazole moieties constitute an

  点击化学已被用作2,6-双（1-芳基-1,2,3-三唑-4-基）吡啶（BTP）的通用扩展杂芳族结构单元，可用于超分子化学，特别是折叠剂和配体设计。除了使用Cu（I）催化的Huisgen型1,3-偶极环加成反应进行高产率合成外，形成的三唑部分还构成了BTP框架的组成部分，并编码了其明显的构象偏好及其螯合能力。在末端芳基和中央吡啶部分上均带有供电子和吸电子取代基的各种对称和非对称BTP已被有效地合成，并且可以容易地用两亲性侧链和卟啉发色团后官能化。在溶液和固态下，BTP支架均采用高度保守的类似马蹄铁的抗-抗构象。在质子化或金属配位时，BTP支架切换为螯合的syn-syn构象。已经制备了铁和euro配合物，通过单晶X射线衍射分析成功表征了铁和euro的配合物，并研究了它们的自旋态和发光性质。扩展的杂芳族BTP支架应被证明对响应性折叠基骨架的设计以及新的磁性和发光材料的制备有用。通过单晶X射线衍射

• Copper(ii)-mediated chiral helicity amplification and inversion of meta-ethynylpyridine polymers with metal coordination sites
  作者：Shunsuke Takashima、Hajime Abe、Masahiko Inouye

  DOI：10.1039/c1cc12358k

  日期：——

  meta-Ethynylpyridine polymers bearing metal coordination sites associate with alkyl glycoside guests to show induced circular dichroism (ICD) bands. The addition of a Cu(II) ion changed the intensity or the sign of these ICD bands. The changes suggested chiral helicity amplification or inversion of the polymers by Cu(II)-mediated cross-linking at the coordinating side chains.
