Discovery of benzimidazole derivatives as modulators of mitochondrial function: A potential treatment for Alzheimer's disease
摘要:
In this study, we designed a library of compounds based on the structures of well-known ligands of the 18 kDa translocator protein (TSPO), one of the putative components of the mPTP. We performed diverse mitochondrial functional assays to assess their ability to restore cells from A beta-induced toxicity in vitro and in vivo. Among tested compounds, compound 25 effectively improved cognitive function in animal models of AD. Given the excellent in vitro and in vivo activity and a favorable pharmacokinetic profile of compound 25, we believe that it can serve as a promising lead compound for a potential treatment option for AD.

This paper reports the transition metal-free C(sp3)−H sulfenylation of arylacetamides by using thiophenols as the sulfenyl reagents. The reactions take place in the presence of only K3PO4. Control experiments indicate that the reactions proceed via a featured sulfur-centred free radical intermediate. In addition, the synthesis of 2-thiomethyl benzoxazoles has been realized via the p-toluenesulfonic
本文报道了使用苯硫酚作为亚苯基试剂对芳基乙酰胺进行无过渡金属的 C( sp 3 )-H 亚苯基化反应。反应仅在 K 3 PO 4存在下发生。对照实验表明反应通过以硫为中心的自由基中间体进行。此外,2-硫甲基苯并恶唑的合成是通过对甲苯磺酸(p- TSA)促进的苯磺酰化产物的环化实现的。

efficient palladium-catalyzed carbonylative cyclization of N-substituted 2-iodobenzamides and 2-iodoanilides was investigated for the synthesis of phthalimides and benzoxazinones, respectively, by usingphenylformate as a CO source. The present catalytic protocol circumvents the use of an expensive phosphine ligand as well as solvent in the case of the phthalimidesynthesis. Moreover, mild reaction conditions
通过使用甲酸苯酯作为 CO 源,研究了一种简单有效的钯催化的 N-取代 2-碘苯甲酰胺和 2-碘苯胺的羰基化环化反应,分别用于合成邻苯二甲酰亚胺和苯并嗪酮。本催化协议在邻苯二甲酰亚胺合成的情况下避免使用昂贵的膦配体以及溶剂。此外,温和的反应条件和对各种官能团的耐受性增强了该方法的普遍适用性。
