Abstract : several - aromaticamino ketones , which were designed according to some hypothetical models of the cyclooxygenase and 5 - lipoxygenase active sites , were synthesized by an amino exchange reaction . the structures of the eight new compounds were confirmed by ir , 1h - nmr and elemental analysis . the results of the pharmacological tests showed some of the investigated compounds had significant anti - inflammatory activity on croton oil - induced ear edema of mice 文摘:根据环氧化酶、 5 -脂氧化酶活性中心结构模型设计了一组-芳胺酮类化合物,并用胺交换反应合成了这些化合物.经红外光谱、核磁共振氢谱及元素分析证实了8个未见文献报道的化合物的结构.药理实验结果显示.部分受试化合物在巴豆油诱发小鼠足趾肿胀模型中表现出一定的抗炎活性
This review focuses on morphological and physiological reactions of fruit tree to water stress . leaf area , root growth and microstructure of leaves and roots were investigated . some physiological and biochemical index of fruit tree leaves and roots under water stress , such as variations of stomatal aperture , photosynthesis , photoinhibition , metabolism of lipoxygenase , content of proline , nuclear acid and endogenous phytohormones , were summarized 从水分胁迫对果树叶、根的形态指标及显微结构,叶片气孔行为、光合作用、光抑制、活性氧代谢、脂氧合酶代谢、多胺代谢、脯氨酸、核酸代谢、内源激素变化等生理生化方面综述了近十几年来的研究成果,为全面研究果树抗旱机理及进一步制定抗旱措施奠定理论基础。
