  摘要：

  通过包含 N-O 螯合咔唑基腙配体的对伞花烃 Ru( II ) 有机金属络合物催化的一锅多组分反应，合成了一系列具有不同取代基功能的具有生物学意义的 2-氨基-4 H-色烯。使用各种光谱（FT-IR、UV-vis、NMR 和 HR-MS）和分析方法合成和表征了一组对伞花烃 Ru( II ) 配合物。借助单晶 X 射线衍射研究证实了其中一种配合物的分子结构。2-氨基-4 H-色烯衍生物已在温和条件下通过钌( II) 催化剂介导的取代苯甲醇、间苯二酚和丙二腈的无受体脱氢偶联。本催化协议提供了各种 2-氨基-4 H-色烯，从各种容易获得的伯醇中以高达 95% 的高产率提供，而无需使用任何利用低催化剂负载的氧化剂/添加剂。通过醛和亚苄基丙二腈中间体的形成以及水和氢作为副产物的排放，已经描述了催化合成 2-氨基-4 H-色烯化合物的合理机制。有趣的是，从合成的 2-氨基-4 H-色烯中成功构建了具有良好收率的药用重要的他克林类似物。

  An efficient synthesis of novel pyrano[2,3-b]pyridine derivatives has been achieved by the cyclocondensation of 2-amino-3-cyano-4H-chromenes and cyclohexanone in the presence of aluminium chloride under controlled microwave irradiation. The experimental conditions have been thoroughly optimized and established, allowing significant rate enhancements and excellent yields. The starting 4H-chromenes were

  The pharmacological analysis of racemic chromenotacrines (CT) 1-7, bearing the 11-amino-12-aryl-8,9,10,12tetrahydro-7H-chromeno[2,3-b]quinolin-3-ol ring skeleton, in a series of experiments targeted to explore their potential use for the treatment of Alzheimer's disease (AD), is reported. The toxicological evaluation showed that among all these chromenotacrines, CT6 is much less hepatotoxic than tacrine in a range of concentrations from 1 to 300 mu M, measured as cell viability in HepG2 cells. Moreover, CT6 did not significantly increase lactate dehydrogenase, aspartate transaminase, and alanine transaminase release in HepG2 cells. Besides, CT6 treatment exerts a high protective effect against the lipid peroxidation induced after H2O2-treated SH-SY5Y cells, in a concentration-dependent manner. cm showed an excellent antioxidant profile in the AAPH test, and protects against the decrease in cell viability induced by respiratory chain inhibitors (Oligomicyn A/Rotenone) and NO donors in neuronal cultures. This effect could be due to a mixed antiapoptotic and antinecrotic neuroprotective effect at low and intermediate CT6 concentrations, respectively. CT1-7 are potent and selective inhibitors of EeAChE in the submicromolar range. CT3 [IC50 (EeAChE) = 0.007 +/- 0.003 mu M], and CT6 IC50 (EeAChE) = 0.041 +/- 0.001 mu M are the most potent AChE inhibitors. Kinetic studies on the non-toxic chromenotacrine CT6 showed that this compound behaves as a non-competitive inhibitor (Ki = 0.047 +/- 0.003 mu M), indicating that CT6 binds at the peripheral anionic site, a fact confirmed by molecular modeling analysis. In silica ADMET analysis showed also that CT6 should have a moderate BBB permeability. Consequently, non-toxic chromenotacrine CT6 can be considered as an attractive multipotent molecule for the potential treatment of AD. (C) 2014 Elsevier Masson SAS. All rights reserved.
