    摘要:
    急性肺损伤(ALI)的致死率很高,白细胞介素6(IL-6)和肿瘤坏死因子-α(TNF-α)在ALI病例中对组织恶化的影响最大。在这项研究中,我们基于先前鉴定的先导化合物设计并合成了一系列新的噻唑并[3,2-a]嘧啶衍生物,并评估了它们的抗炎活性。结构-活性关系研究导致发现了两种高效抑制剂。发现这两种有前途的化合物以剂量依赖性方式抑制小鼠原发性腹膜巨噬细胞(MPM)中脂多糖(LPS)诱导的IL-6和TNF-α释放。此外,这些化合物的施用导致肺组织病理学改善并且在体内减弱了LPS诱导的ALI。综上所述,这些数据表明这些新颖的噻唑罗[3,

  • Synthesis of 2-substituted pyrimidines and benzoxazoles via a visible-light-driven organocatalytic aerobic oxidation: enhancement of the reaction rate and selectivity by a base

    An efficient visible-light-driven photocatalytic oxidation of various 2-substituted dihydropyrimidines and phenolic imines has been achieved using an organic photocatalyst eosin Y bis(tetrabutyl ammonium salt) (TBA-eosin Y) and inexpensive oxidant molecular oxygen. With the aid of a base, significantly enhanced photoinduced electron transfer from substrates dihydropyrimidines or phenolic imines to the excited state of TBA-eosin Y has enabled the aerobic oxidation to yield 2-(methylthio)pyrimidines or 2-arylbenzoxazoles selectively.

  • Effect of high pressure on Biginelli reactions. Steric hindrance and mechanistic considerations
    作者:Gérard Jenner
    DOI:10.1016/j.tetlet.2004.05.106
    日期:2004.8
    The effect of high pressure is examined in 3-CC Biginelli reactions. This effect is small when moderately hindered aldehydes or ureas are involved. However, particularly in the case of bulky aldehydes, the sensitivity of the reaction to pressure increases with increasing steric congestion in line with earlier studies described in the reference list. The results also provide insights into the mechanism
    在3-CC Biginelli反应中检查了高压的影响。当涉及中度受阻的醛或脲时,这种作用很小。但是,特别是在大体积醛的情况下,反应对压力的敏感性会随着空间拥堵的增加而增加,这与参考文献中所述的早期研究相一致。结果还提供了对该机制的见解。这样的结果突显了高压活化在制备受阻Biginelli产品中的合成效用。
  • Facile Biginelli-Type Reactions Catalysed by Super Acidic Ionic Liquid under Solvent-Free Conditions
    作者:Liang Wang、Min Zhou、Qun Chen、Ming-Yang He
    DOI:10.3184/174751912x13518654161237
    日期:2012.12
    [MeC(OH)2]+ClO4- as a super acidic ionic liquid is an extremely active catalyst for Biginelli-type reactions. The present method is especially effective for the inactive aliphatic aldehydes. The solvent-free conditions, high catalytic activity, wide substrates tolerance and convenient product isolation make the protocol more advantageous.

    The Biginelli reaction, a one-pot condensation of aldehydes, urea or thiourea, and β-dicarbonyl compounds, is efficiently catalyzed by samarium diiodide. The biologically active dihydropyrimidinones are easily synthesized in moderate to excellent yields under solvent-free conditions. (© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2005)
