  Discovery of novel benzofuran-based compounds with neuroprotective and immunomodulatory properties for Alzheimer's disease treatment

  摘要：

  To address the multifactorial nature of Alzheimer's Disease (AD), a multi-target-directed ligand approach was herein developed. As a follow-up of our previous studies, a small library of newly designed 2-arylbenzofuran derivatives was evaluated towards cholinesterases and cannabinoid receptors. The two most promising compounds, 8 and 10, were then assessed for their neuroprotective activity and for their ability to modulate the microglial phenotype. Compound 8 emerged as able to fight AD from several directions: it restored the cholinergic system by inhibiting butyrylcholinesterase, showed neuroprotective activity against A beta(1-42) oligomers, was a potent and selective CB2 ligand and had immunomodulatory effects, switching microglia from the pro-inflammatory M1 to the neuroprotective M2 phenotype. Derivative 10 was a potent CB2 inverse agonist with promising immunomodulatory properties and could be considered as a tool for investigating the role of CB2 receptors and for developing potential immunomodulating drugs addressing the endocannabinoid system.

  iron-catalyzed cross-electrophile coupling of aryl chlorides with unactivated alkyl chlorides via an iron/B2pin2 catalytic system has been developed. (Hetero)aryl chlorides undergo this transformation smoothly under mild conditions, furnishing the alkylated products with good efficiency. This protocol features excellent functional group compatibility and gram-scale synthesis, which also enables the late-stage functionalization

  已经开发了通过铁/B 2 pin 2 催化体系进行铁催化芳基氯与未活化的烷基氯的交叉亲电子偶联的例子。 (杂)芳基氯在温和条件下顺利进行这种转化，以良好的效率提供烷基化产物。该方案具有良好的官能团兼容性和克级合成能力，也能够实现生物活性分子的后期功能化，从而为药物化学的发展提供了绝佳的机遇。初步实验和计算研究表明该反应可能涉及Fe 0 /Fe II /Fe 0 /Fe催化循环。两个Li与铁的协同作用对于通过氧化加成和阳离子辅助单电子转移途径激活芳基-Cl和烷基-Cl至关重要。
