A one-step method for the synthesis of aromatic indolizine derivatives byintramolecular 1,5-dipolar cyclization reaction of 2-(2-arylethenyl)pyridinium N-ylidesin the presence of an oxidant has been studied for the first time. In the presence ofelectron-deficient olefins, however, 2-(2-phenylethenyl)pyridinium N-ylides underwent1,3-dipolar cycloadditions and then aromatized in situ by TPCD to produce indolizinederivatives, indicating 1,3-dipolar cycloaddition proceed more readily than 1 ,5-dipolarcyclization in these conditions. Pyridinium disubstituted N-ylides, readily obtainedfrom corresponding pridinium and β-chlorovinyl ketone, underwent thermalintramolecular 1,5-dipolar cyclization to give indolizine derivatives easily.Indolizinecarbaldehyde derivatives were synthesized starting from 2-pyridinecarbaldehyde in four-steps involving 1,3-dipolar cycloaddition reaction.

The viscosity properties of break flour, middling flour, and oat flour (mixture of break flour and middling flour with nature milling ratio) were investigated. The results showed that after high-temperature treatment, the average gelatinization temperature of break flour, middling flour and oat flour decreased significantly, which were lower than that of oat without high-temperature treatment. Their peak viscosity, final viscosity and hold viscosity increased both under air-heating (140℃, 155℃) and far-infrared heating (200℃), compared with non-treated samples. With the temperature of high-temperature effects treatment increasing gradually, their viscosity properties decreased.

The eukaryotic translation initiation factor 5A (eIF-5A) is a small acidic protein (18k Da), widely presents in all organisms from archebacteria to mammals but not in eubacteria, with highly conserved sequences. eIF5A is unique in that it is the only protein known to contain the unusual amino acid residue hypusine (hydroxyputrescine-lysine), which is essential for eIF5A function and is formed by post-translational modification of a specific lysine residue.
真核生物翻译起始因子5A(eIF5A)是一个分子量约18 kDa的酸性蛋白,其序列从古细菌到哺乳动物高度保守,并广泛存在于各种真核生物细胞中。eIF5A是迄今为止唯一一种已知含有特殊氨基酸残基hypusine的蛋白质。hypusine是一种蛋白翻译后修饰产物,它的形成对eIF5A的功能完整至关重要,相关的研究结果表明hypsine在控制细胞周期循环的过程当中扮演着一个重要的角色。
