  proposed binding mode of the preferred substrate, Aβ3E−42. An in vitro structure–activity relationship study identified several excellent QC inhibitors demonstrating 5- to 40-fold increases in potency compared to a known QC inhibitor. When tested in mouse models of AD, compound 212 significantly reduced the brain concentrations of pyroform Aβ and total Aβ and restored cognitive functions. This potent Aβ-lowering

  谷氨酰胺基环化酶（QC）通过产生β淀粉样肽（pGlu-Aβ）的N末端焦谷氨酸与毒性淀粉样蛋白斑块的形成有关，因此可能参与了阿尔茨海默氏病（AD）的发病机理。我们基于优选底物Aβ3E-42的拟议结合模式设计了谷氨酰环化酶（QC）抑制剂库。一项体外结构-活性关系研究确定了几种出色的QC抑制剂，与已知的QC抑制剂相比，其效能提高了5至40倍。在AD的小鼠模型中测试时，化合物212显着降低了焦状Aβ和总Aβ的大脑浓度，并恢复了认知功能。这种强大的Aβ降低作用是通过将一个额外的结合区并入我们先前建立的药效团模型中而实现的，从而导致在QC结合位点与Glu327的羧酸酯基团发生强相互作用。我们的研究为设计新型QC抑制剂作为AD的潜在治疗方法提供了有用的见识。

  A palladium-catalyzed difluoromethylation of a series of heteroaryl chlorides, bromides and iodides under mild conditions is described. A wide range of heteroaryl halides such as pyridyl, pyrimidyl, pyrazyl, funanyl, thienyl, pyazolyl, imidazolyl, thiazolyl, and oxazolyl halides were efficiently difluoromethylated, thus providing medicinal chemists an alternative choice for the preparation of drug
