Conjugates of tacrine and salicylamide were synthesized as potential multifunctional anti-AD agents. The compounds have high anticholinesterase (IC50 AChE to 0.22 μM, IC50 BChE to 0.01 μM) and low anti-CES activity, displaced propidium iodide from the AChE PAS, being in agreement with the results of molecular docking. The conjugates exhibited ABTS+-scavenging (TEAC to 0.9) and metal-chelating activity
他克林和水杨酰胺的结合物被合成为潜在的多功能抗 AD 剂。这些化合物具有高抗胆碱酯酶(IC 50 AChE 至 0.22 μM,IC 50 BChE 至 0.01 μM)和低抗 CES 活性,从 AChE PAS 中取代了碘化丙啶,与分子对接的结果一致。缀合物表现出ABTS + -清除(TEAC至0.9)和金属螯合活性。

Die Erfindung betrifft als neue Substanzen N-Octylsalicylsäureamid und N-Decyl-salicylsäureamid, ein Verfahren zur Herstellung der genannten Verbindungen aus Salicylsäuremethylester und einem primären Amin sowie die Verwendung der Amide in antimikrobiell wirkenden Zusammensetzungen.
Stilbene, a kind of phytoalexin, plays an important role in resistance to fungal and bacterial infection in plants. It strongly inhibits the growth of fungi and sprout of spore. Stilbene synthase gene (Vst1) obtained from grapevine has been transferred into common spring wheat Jinghong 5 by using the biolistic transformation method. Five transgenic plants (T-0) were obtained from the bombarded 2014 immature embryos. One immune plantlet and 3 plantlets with mid-resistance to powdery mildew were identified from the transgenic plants of T-3 generation which came from 2 T-0 transgenic plants.
Lipase-Catalyzed Solvent-Free Amidation of Phenolic Acids
A series of N-alkyl-substituted amides, based on various phenolic acids, have been synthesized by the condensation of equimolar amounts of phenolic acids with different alkyl amines in the presence of Candida antarctica lipase at 60-90 degrees C in 16-20 h. The reactions were carried out in a solvent-free system without the use of any activating agents. All the products were obtained in appreciable amounts and the yields for different compounds varied between 75.6% and 83.5%. The synthesized compounds were characterized using spectroscopy techniques, namely infrared and NMR (H-1 and C-13).

salicylic acid derivatives exhibit glutathioneperoxidase (GPx)-like activities higher than or equal to ebselen [Yu et al., Chem. Eur. J., 2008, 14, 7066; Org. Biomol. Chem., 2010, 8, 828]. For understanding the absence of GPx-like activity of the homologue of 5-seleninic anhydride of salicyloylglycine with a loger side chain, we have further synthesized 19 new derivatives (5-seleninic acids of methyl
先前我们已经表明,一些5-硒化水杨酸衍生物表现出的谷胱甘肽过氧化物酶(GPx)样活性高于或等于依伯硒仑[Yu et al。,Chem。欧元。J.,2008,14,7066; 单位 生物分子 化学 ,2010,8,828]。为了解不存在具有loger侧链的水杨酰甘氨酸5-硒酸酐的同系物没有GPx样活性的情况,我们进一步合成了19种新衍生物(甲基或苯基水杨酸酯的5-硒酸,N-水杨酰ω-羧烷基胺或ñ-水杨酰基烷基/苯基胺,及其一些二硒化物)。某些带有长侧链或环己基的5-硒酸,无论其衍生自ω-羧烷基胺还是简单的烷基胺,都没有GPx样的活性。缺乏类似GPx的活性,使我们可以定量地将上述3个系列同源物的GPx活性与其疏水性(ClogP)相关联,在每个系列中均显示出令人满意的相关性。然后将分子疏水性广泛应用于包括二芳基二硒化物和依布硒仑衍生物在内的各种已知的芳香族硒GPx模拟物,以相对定量的方式解释其G
