  Synthesis of Dithiolethiones and Identification of Potential Neuroprotective Agents via Activation of Nrf2-Driven Antioxidant Enzymes

  摘要：

  Oxidative stress is implicated in the pathogenesis of a wide variety of neurodegenerative disorders, and accordingly, dietary supplement of exogenous antioxidants or/and upregulation of the endogenous antioxidant defense system are promising for therapeutic intervention or chemoprevention of neurodegenerative diseases. Nrf2, a master regulator of the cellular antioxidant machinery, cardinally participates in the transcription of cytoprotective genes against oxidative/electrophilic stresses. Herein, we report the synthesis of 59 structurally diverse dithiolethiones and evaluation of their neuroprotection against 6-hydroxydopamine- or H2O2 -induced oxidative damages in PC12 cells, a neuron-like rat pheochromocytoma cell line. Initial screening identified compounds 10 and 11 having low cytotoxicity but conferring remarkable protection on PC12 cells from oxidative-mediated damages. Further studies demonstrated that both compounds upregulated a battery of antioxidant genes as well as corresponding genes' products. Significantly, silence of Nrf2 expression abolishes cytoprotection of 10 and 11, indicating targeting Nrf2 activation is pivotal for their cellular functions. Taken together, the two lead compounds discovered here with potent neuroprotective functions against oxidative stress via Nrf2 activation merit further development as therapeutic or chemopreventive candidates for neurodegenerative disorders.

  The comprehensive study of the reactions of carbonyl compounds and ethyl diazoacetate in the presence of a Brønsted acid catalyst is described. In result, a broad range of 3-oxo-esters were synthesized from a variety of ketones and aliphatic aldehydes by 1,2-aryl/alkyl/hydride shift. Aryl–methyl ketones produced only aryl-migrated products, whereas other ketones yielded a mixture of products. For diaryl

  Iron-catalysed 1,2-acyl migration of tertiary α-azido ketones and 2-azido-1,3-dicarbonyl compounds provides a simple and atom-economical approach toward enamides and isoquinolones. This paper reports two catalyst systems for these transformations which employ iron(II) complexes [Fe(dpbz)]Br2 (dpbz = 1,2-bis(diphenylphosphino)benzene) and FeBr2/Et3N, respectively. [Fe(dpbz)]Br2 was found to be highly

  铁催化的α-叠氮基酮和2-叠氮基-1,3-二羰基化合物的1,2-酰基迁移为酰胺和异喹啉酮提供了一种简单且原子经济的方法。本文报道两种催化剂体系用于这些转化其采用铁（II）配合物的[Fe（dpbz）]溴2（dpbz = 1,2-双（二苯基膦基）苯）和FeBr 2 / ET 3 N，分别。发现[Fe（dpbz）] Br 2在将2-叠氮基-2,3-二氢-1 H-茚满-1-酮转化为异喹诺酮方面非常有效。另一方面，由于Et 3的有益作用，FeBr 2 / Et 3 N的试剂组合具有更宽的催化范围N.后一种催化剂体系可使2-叠氮基-2-甲基-1,3-二羰基化合物在温和条件下以良好的收率转化为相应的酰胺。
