  2-Arylbenzofuran-based molecules as multipotent Alzheimer's disease modifying agents

  摘要：

  The complex etiology of Alzheimer's disease prompts scientists to develop multi-target strategies to combat causes and symptoms. In line with this modern paradigm and as a follow-up to our previous studies, we designed and synthesized a focused collection of new 2-arylbenzofurans and evaluated their biological properties towards specific targets involved in AD, namely human AChE and human BuChE, and A beta fibril formation. Selected compounds were also tested for their ability to inhibit A beta neurotoxicity in terms of neuronal viability loss, and to prevent A beta peptide-binding to cell membrane and intracellular reactive oxygen species (ROS) formation. The different modifications introduced in the structure of our lead compound led to an increase in activity towards one or more of the selected targets: the anticholinesterase activity of some compounds was found to be significantly higher than previously obtained related molecules, and the compounds also proved to possess A beta anti-aggregating properties and neuroprotective effects. The most interesting multi-target compounds were 18, and 1. Interestingly, 1 also showed good selectivity and moderate affinity for CB1 receptor, opening new perspectives in the field of research on AD, since cannabinoid ligands have been widely reported to have neuroprotective properties.

  Multi-target strategy to address Alzheimer’s disease: Design, synthesis and biological evaluation of new tacrine-based dimers

  摘要：

  The multifactorial nature of Alzheimer's disease (AD) offers us a textbook example where parental compounds, mostly marketed, are modified with the aim of improving and/or conferring two or even more biological activities to contrast or less frequently revert the disease's symptoms. This is the case of tacrine and its dimeric derivative bis(7)-tacrine which, for instance, paved the way for the development of a broad collection of very interesting homo- and heterodimeric structures, conceived in light of the emerging multi-target approach for AD-related drug discovery. As a contribution to the topic, we report here the design, synthesis and biological evaluation of 12 compounds referable to bis(7)-tacrine. In addition to the cholinesterase activity, some of the selected compounds (7-9 and 12) were capable of inhibiting the non-enzymatic function of AChE and/or showed a remarkable activity against BACE1. Thus, the present study outlines a series of newly synthesized molecules, structurally related to bis(7)-tacrine, endowed with extended biological profile in agreement with the emerging multi-target paradigm.

  meta‐substituted phenols in which a single palladium catalyst accomplishes a Suzuki–Miyaura cross‐coupling between a β‐chlorocyclohexenone and an arylboronic acid, and oxidation of the resulting cyclohexenone to the corresponding phenol upon introduction of a terminal oxidant and electron transfer mediator. Notably, this method also allows ready access to ortho, meta‐disubstituted phenols, sterically congested

  我们报告了一种合成间位取代酚的新方法，其中单个钯催化剂完成了β-氯代环己烯酮和芳基硼酸之间的Suzuki-Miyaura交叉偶联，并在引入环戊烯酮之后将所得环己烯酮氧化为相应的苯酚末端氧化剂和电子转移介体。值得注意的是，这种方法还可以方便地使用邻位，间-二取代的苯酚，空间上拥挤的联芳基苯酚以及更高度取代的苯酚。

  synthetic method for the preparation of benzofurans has been developed. The key step of this method is the [3,3]-sigmatropic rearrangement of N-trifluoroacetyl-ene-hydroxylamines, which was triggered by acylation of oxime ethers. TFAA has been proved to be the best reagent to induce [3,3]-sigmatropic rearrangement for the synthesis of cyclic oracyclic dihydrobenzofurans. On the other hand, the TFAT-DMAP

  An efficient and practical method for construction of 2-arylbenzo[b]furans from 2-methoxychalcone epoxides has been reported. Catalyzed by 2 mol % of BF3·Et2O, 2-methoxychalcone epoxides went through the Meerwein rearrangement, followed by deformylation in one-pot to successfully afforded 2-methoxydeoxybenzoins. Afterward, 2-arylbenzo[b]furans were obtained in high yields (87%–100%) via intermolecular
