  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.

  光氧化还原和卡宾联合催化从羧酸合成 α-氨基酮

  摘要：

  α-氨基酮部分存在于许多药理活性分子中，但它们的合成具有挑战性。在此，我们报告了一种温和、操作简单的方法，通过卡宾和光氧化还原催化的结合，将羧酸中的 α-氨基 C(sp 3 )-H 键直接酰化。具体来说，广泛的羧酸、一类原料化学品和容易获得的N之间的交叉偶联反应-烷基苯胺通过单电子N-杂环卡宾催化结合光催化提供了获得结构多样的α-氨基酮的途径。该方法具有广泛的底物范围，并与广泛的官能团兼容。为了证明该方法的潜在应用，我们对一种 α-氨基酮产品进行了进一步的转化。

  One-pot reduction-triggered heterocyclizations from 2-nitrophenols to benzoxazoles and from 1-aryl-2-nitroethanones to oxazoles were investigated. In the presence of indium/AcOH in benzene at reflux, 2-nitrophenols and R-C(OMe)(3) (R=H, Me, Ph) produced excellent yields of corresponding benzoxazoles within an hour. Similarly, 1-aryl-2-nitroethanones and Ph-C(OMe)(3) in the presence of indiurn/AcOH in acetonitrile transformed into the corresponding oxazoles with good yields. (c) 2009 Elsevier Ltd.
