标题:淀粉基仿生谷胱甘肽过氧化物酶的构建及其催化机制
摘要:谷胱甘肽过氧化物酶(gpx)是人体重要的含硒抗氧化酶.仿生gpx的制备及其催化行为的模拟对于抗氧化药物的开发具有重要意义.目前已报道的基于大分子的仿生硒酶大多难以降解,限制了其在医疗,保健,功能食品等领域的应用.为解决这一问题,本文以糯玉米淀粉酯化制备的辛烯基丁二酸改性淀粉(osa淀粉)为原料,合成了一种新型硒功能化淀粉(se-Starch). Osa淀粉与硒化氢钠反应.这种硒淀粉作为一种仿生硒酶,其特征在于1 H NMR,Eds,Xps,Sem,Xrd 和 Ft-Ir.催化活性为2.48 μm.min-1的se-淀粉表现出典型的饱和动力学和酶学催化行为.这种催化活性是代表小分子仿生gpx的phseseph的1.04x10 5倍.催化机理研究表明,与淀粉结合的辛烯基琥珀酸分子赋予其疏水性微环境,有利于疏水性底物的结合,从而提高催化活性.该工作不仅为构建基于天然聚合物的仿生gpx提供了新思

权利人:AIR PROD & CHEM
摘要:A process is described for the synthesis of an aryl sulfur pentafluoride compound. In one embodiment of the present invention, there is provided a process for preparing an aryl sulfurpentafluoride compound comprising: combining an at least one aryl sulfur compound with a fluorinating agent to at least partially react and form an intermediate aryl sulfurtrifluoride product; and exposing the intermediate aryl sulfurtrifluoride product to the fluorinating agent and optionally a fluoride source to at least partially react and form the aryl sulfurpentafluoride compound.

权利人:RHODIA CHIMIE SA
摘要:The invention relates to a nucleophilic reagent which is useful for grafting a substituted difluoromethyl group onto a compound containing at least one electrophilic function, or for the synthesis of oxysulphide-containing and fluorine-containing organic derivatives, wherein said reagent comprises:a) a fluorocarboxylic acid of formula Ew-CF2-COOH where Ew represents an electron-withdrawing atom or group, at least partially salified with an organic or inorganic cation, andb) a polar aprotic solvent;and in that the content of releasable protons carried by its various components, including their impurities, is at most equal to half the initial molar concentration of the said fluorocarboxylic acid.A synthetic process uses this reagent by heating in order to graft a substituted difluoromethyl group onto various compounds.
