  摘要：

  报道了使用非亲核烷基作为亲核试剂的光活化的AlCl 3催化炔烃的区域选择性分子内亲核环化反应。光激发后，邻烷基苯基炔基酮可以转移到（E）-光烯醇中。因此，由非亲核烷基形成亲核亚甲基。AlCl 3催化剂可以稳定（E）-光烯醇中间体，并促进进一步的分子内亲核环化。DFT计算表明，AlCl 3催化的环化是区域选择性的决定步骤。

  In the effort of finding novel acetyl cholinesterase (AChE) inhibitors to improve the efficacy of Alzheimer’s disease (AD) treatment, series of substituted aryl-1´-methyldispiro[indan-2,2´ pyrrolidine-3´,2-indan]-1,3,1-trione and substituted 7´-aryl-5´,6´,7´,7a´-tetrahydrodispiro-[indane-2,5´-pyrrolo[1,2-c][1,3]thiazole-6´,2-indan]-1,3,1-trione analogues were synthesized using [3+2]-cycloaddition reactions. These newly synthesized pyrrolidine compounds were assayed for their biological activity using Ellman’s method. The structural elucidation of the compounds was performed by using 1H-NMR, 13C-NMR, ESI-MS spectra and elemental analyses. Eight out of twenty synthesized compounds showed more than 50% inhibition at concentration of 10 µM. Compound 2e, 2i and 3e were among the most active one, giving IC50 value as 3.3 M for 2e, 3.7 µM for 2i and 5.5 µM for 3e, respectively. Lineweaver-Burk plot indicated that 2i inhibits AChE in a competitive manner. Molecular modelling study was performed to disclose the binding interaction of these compounds with the active site of AChE.

  inhibition of ROS production in LPS-stimulated RAW 264.7 macrophages. Among all the tested compounds, 6-hydroxy-2-(2-(trifluoromethoxy) benzylidene)-2,3-dihydro-1H-inden-1-one (compound 44) showed the strongest inhibitory activity of ROS production. Further studies on the mode of action revealed that compound 44 potently suppressed LPS-stimulated ROS production via modulation of NADPH oxidase. The findings

  To develop effective therapeutics for inflammatory bowel disease (IBD), 2-benzylidene-2,3-dihydro-1-Hinden-1-one and benzofuran-3(2H)-one derivatives, were designed and synthesized and their structure activity relationships (SAR) were investigated. Compounds 7, 25, 26, 32, 39, 41, 52, 54, and 55 showed potent inhibitory effect (>70%) on the TNF-alpha-induced adhesion of monocytes to colon epithelial cells, which is one of the hallmark events leading to IBD. Such inhibitory activity of the compounds correlated with their suppressive activities against the TNF-alpha-induced production of ROS; ICAM-1 and MCP-1 expression, critical molecules involved in monocyte-epithelial adhesion; and NF-kappa B transcriptional activity. In addition, compounds 41 and 55 significantly suppressed the lipopolysaccharide (LPS)-induced expression of the TNF-alpha gene, with compound 55 showing better efficacy. This inhibition of TNF-alpha expression by compounds 41 and 55 corresponded to their additional inhibitory activity against AP-1 transcriptional activity, which is another transcription factor required for high level TNF-alpha expression. The strong inhibitory activity of compound 55 against an in vivo colitis model was confirmed by its dose dependent inhibitory activity in a rat model of 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced colitis, demonstrating compound 55 as a new potential candidate for the development of therapeutics against IBD.
