[EN] AMINE COMPOUNDS HAVING ANTI-INFLAMMATORY, ANTIFUNGAL, ANTIPARASITIC AND ANTICANCER ACTIVITY [FR] COMPOSÉS AMINE AYANT UNE ACTIVITÉ ANTI-INFLAMMATOIRE, ANTIFONGIQUE, ANTIPARASITAIRE ET ANTICANCÉREUSE
o-, m- and p-alkyloxybenzohydroxamic acids were synthesized and subjected to the examination for antibacterial and antifungal activity. All the hydroxamic acids tested were almost ineffective for pathogens examined of Enterobacteriaceae, but some of alkyloxybenzo- and fatty acyl-hydroxamic acid were found to be as highly effective for pathogenic fungi as butyl p-hydroxybenzoate being used as a comparison. The increase of carbon number of p-alkyloxybenzo- and fatty acyl-hydroxamic acid led to the increase in their antifungal activity, reached to the maximum at C6 in alkyloxy moiety and C10 in fatty acyl derivatives, and then the gradual decrease in both series. Considering the inhibitory power of hydroxamic acid on plant and bacterial urease, we discussed the possible correlation between antimicrobial activity and inhibitory powers on urease activity of the compounds.

isomers showed peaks at m/z 77 for the phenyl anion and m/z 93 for the phenoxyl anion, in addition to that for the ortho-specific enolate anion. Under high collision energy, the ortho isomers also produce a peak at m/z 137 for an alkene loss. The spectra of meta and para compounds show a peak at m/z 92 for the distonic anion produced by the homolysis of the O-C bond. Moreover, a small peak at m/z 136 for
碰撞诱导的衍生自邻烷氧基苯甲酸的阴离子的解离提供了一种生产气态烯醇式阴离子的简便方法。最初损失CO(2)后产生的烷氧基苯基阴离子通过邻位异构体所特有的双氢转移机理消除了苯分子,从而形成了烯醇式阴离子。氘标记研究证实,苯损失中转移的两个氢原子起源于烷基链的位置1和2。氢原子从C-1位置的初始转移形成了苯基阴离子和羰基化合物,两者均以离子/中性络合物的形式紧密结合。通过消除中性羰基化合物,该络合物要么直接断裂以生成苯基阴离子,或通过从C-2位置转移氢原子并在此过程中消除苯分子而形成烯酸酯阴离子。与将氘原子从C-2位置转移相比,当氘原子从C-1位置转移时观察到的明显的主要动力学同位素效应表明,第一次转移是速率确定步骤。量子力学计算表明,苯的中性损失是热力学上有利的过程。在所使用的条件下,除了邻位特异性烯醇根阴离子外,仅邻位异构体的光谱在m / z 77处显示出苯基阴离子峰,在苯氧基阴离子中显示出m

nitride material can be combined with homogeneous nickel catalysts for light-mediated cross-couplings of aryl bromides with alcohols under mild conditions. The metal-free heterogeneous semiconductor is fully recyclable and couples a broad range of electron-poor aryl bromides with primary and secondaryalcohols as well as water.
