  摘要：

  在绝对DMF中黄酮醇（flaH）的钾盐的氧合导致O-苯甲酰水杨酸钾和一氧化碳在40°C时产率为95％。动力学测量得出速率定律-d [flaK] / dt = k（2 ）[flaK] [O（2）]。速率常数，激活焓和313.16 K处的熵如下：k（2）/ M（-）（1）s（-1）=（3.28 +/- 0.10）x 10（-1），DeltaH（ ）/ kJ mol（-1）= 29 +/- 2，DeltaS / J mol（-1）K（-1）= -161 +/-6。该反应符合4'-取代的Hammett线性自由能关系黄酮醇和释放电子的基团使氧化反应更快。4'-取代的黄酮酸酯的阳极氧化波电势E（a）与反应速率密切相关。在更多的负E（a）值观察到更快的反应速率。反应混合物的EPR光谱（g = 2.0038，dH = 1.8 G，a（H）= 0。

  A synthetic route to 2-O-(diphenylacetyl)salicylic acid derivatives was developed and the effects of the products on the heat-denaturation of albumin and on heat-induced erythrocytolysis were examined (in vitro anti-inflammation test). Trichloroethyl salicylate was acylated with diphenylacetic acid and its derivatives in the presence of methanesulfonyl chloride and pyridine, and the products were deprotected with zinc-acetic acid to give 2-O-(diphenylacetyl)salicylic acid derivatives. Their biological effects resembled those of ibuprofen.

• Benzoylsalicylic acid derivatives as defense activators in tobacco and Arabidopsis

  Systemic acquired resistance (SAR) is a long lasting inducible whole plant immunity often induced by either pathogens or chemical elicitors. Salicylic acid (SA) is a known SAR signal against a broad spectrum of pathogens in plants. In a recent study, we have reported that benzoylsalicylic acid (BzSA) is a SAR inducer in tobacco and Arabidopsis plants. Here, we have synthesized BzSA derivatives using SA and benzoyl chlorides of various moieties as substrates. The chemical structures of BzSA derivatives were elucidated using Infrared spectroscopy (IR), Nuclear magnetic spectroscopy (NMR) and High-resolution mass spectrometer (HRMS) analysis. The bioefficacy of BzSA derivatives in inducing defense response against tobacco mosaic virus (TMV) was investigated in tobacco and SA abolished transgenic NahG Arabidopsis plants. Interestingly, pre-treatment of local leaves of tobacco with BzSA derivatives enhanced the expression of SAR genes such as NPR1 [Non-expressor of pathogenesis-related (PR) genes 1], PR and other defense marker genes (HSR203, SIP1C, WIPK) in systemic leaves. Pre-treatment of BzSA derivatives reduced the spread of TMV infection to uninfected areas by restricting lesion number and diameter both in local and systemic leaves of tobacco in a dose-dependent manner. Furthermore, pre-treatment of BzSA derivatives in local leaves of SA deficient Arabidopsis NahG plants induced SAR through AtPR1 and AtPR5 gene expression and reduced leaf necrosis and curling symptoms in systemic leaves as compared to BzSA. These results suggest that BzSA derivatives are potent SAR inducers against TMV in tobacco and Arabidopsis. (C) 2017 Elsevier Ltd. All rights reserved.
