  Core Refinement toward Permeable β-Secretase (BACE-1) Inhibitors with Low hERG Activity

  摘要：

  By use of iterative design aided by predictive models for target affinity, brain permeability, and hERG activity, novel and diverse compounds based on cyclic amidine and guanidine cores were synthesized with the goal of finding BACE-1 inhibitors as a treatment for Alzheimer's disease. Since synthesis feasibility had low priority in the design of the cores, an extensive synthesis effort was needed to make the relevant compounds. Syntheses of these compounds are reported, together with physicochemical properties and structure-activity relationships based on in vitro data. Four crystal structures of diverse amidines binding in the active site are deposited and discussed. Inhibitors of BACE-1 with 3 mu M to 32 nM potencies in cells are shown, together with data on in vivo brain exposure levels for four compounds. The results presented show the importance of the core structure for the profile of the final compounds.

  双金属N-杂环碳烯配合物（M = Au和Pd）-官能化UiO-67 MOF，用于炔​​烃水合-铃木偶联串联反应

  摘要：

  金属N-杂环卡宾配合物（NHC-M）已被认为是一类重要的有机金属催化剂。在这里，我们证明了不同的NHC-M（M = Au和Pd）物种可以通过在溶剂热条件下直接组装NHC-M装饰的配体和金属离子而同时引入单个金属有机骨架（MOF）。获得的具有不同有机金属NHC-M物种的UiO-67-Au / Pd-NHBC MOF可以是高度可重复使用的双重催化剂，以依次促进炔烃水合-Suzuki偶联反应。通过依次制备更多用于各种有机转化的这种新型多催化剂，突显了该策略的潜在用途。

  A range of arylboronic acids undergo a homocoupling reaction in the presence of catalytic amount of gold salts to yield symmetrical biaryls. Alkenylboronic acids, arylboronic esters, and arylborates also participate in the gold-catalyzed homocoupling reaction.

  While phenols are frequent and convenient aryl sources in cross-coupling, typically as sulfonate esters, the direct cross-Ullmann coupling of two different sulfonate esters is unknown. We report here a general solution to this chal-lenge catalyzed by a combination of Ni and Pd with Zn reductant and LiBr as an additive. The reaction has broad scope, as demonstrated in 33 examples (65% ± 11% ave yield)

  虽然苯酚是交叉偶联中常见且方便的芳基来源，通常作为磺酸酯，但两种不同磺酸酯的直接交叉乌尔曼偶联尚不清楚。我们在此报告了针对这一挑战的通用解决方案，该解决方案由 Ni 和 Pd 与 Zn 还原剂和 LiBr 作为添加剂的组合催化。该反应具有广泛的范围，如 33 个实例所示（平均产率 65% ± 11%）。机理研究表明，Pd 强烈偏好三氟甲磺酸芳基酯，Ni 催化剂对甲苯磺酸芳基酯的偏好较小，催化剂之间的芳基转移由 Zn 介导，Pd 通过消耗芳基锌中间体来提高产率。
• Synthesis of a carbon-11 radiolabeled BACE1 inhibitor

  Beta-secretase (BACE1), a transmembrane aspartyl protease, can cleave membrane-bound beta-amyloid precursor proteins (APPs) to initiate the accumulation of amyloid-beta (A beta). The inhibition of BACE-1 to limit the accumulation of neurotoxic A beta peptides could offer a potential treatment for Alzheimer's Disease (AD). However, little is known about the distribution and density of BACE1 in the central nervous system. As a step toward filling this gap in knowledge, we have evaluated a potential radiotracer for the imaging of BACE1 using positron emission tomography (PET). A BACE1 inhibitor, 5, is reported with blood-brain barrier (BBB) permeability and high binding affinity. To characterize the pharmacokinetics and distribution of 5 in the brain, we radiolabeled 5 with carbon-11. Using PET, we found that [C-11]5 shows moderate uptake in the brain when administered intravenously to rodents and further work will be performed in animal models to test its application as a PET imaging probe for the central nervous system. Our study demonstrates the effectiveness of PET at providing brain pharmacokinetic data for BACE1 inhibitors, crucial for the development of treatments for AD where CNS penetration is critical.
