摘要:由1,2,4-三甲氧基苯(i)2-甲基-5,7,8-三甲氧基-1,4-萘醌(viii)合成2-甲基-3-丙酮基-7-甲氧基萘(xiie)(xiie))进行.与我们先前的实验相反,与3-甲基-5,7,8-三甲氧基-1,4-萘醌(xvii)的类似加成反应可显着简化麦考宁(xxa)的合成.如预期的那样,爪哇霉素(xxa)和异爪哇霉素(xiie)在uv,Ir,NMR中显示.质谱图没有或只有很小的差异,在结构上无法解释,而两种物质的混合样品却给出了令人惊讶的大的熔点降低.

权利人:MANSOORI G ALI; UNIV ILLINOIS
摘要:Systems and methods for synthesizing silver nanoparticles (SNPs) using Trichoderma fungi have been developed. In an aspect, Trichoderma reesei was used for the extracellular synthesis of silver nanoparticles. In the biosynthesis of metal nanoparticle by a fungus, one or more enzymes or metabolites are produced that reduce a salt to its metallic solid nanoparticles through a catalytic process.

权利人:UNIV JEFFERSON
摘要:A process for the synthesis and delivery of bioactive compounds, compounds that have a therapeutic, biochemical, or immunologic, effect on an animal, such as human. In the process, clavibacter is genetically altered so that it synthesizes the bioactive compound. A plant may be infected with the genetically altered clavibacter and used an as oral delivery system.

权利人:UNIV IOWA RES FOUND
摘要:The present invention provides novel methods for the synthesis of racemic and enantiomers of modafinil via microbial oxidation-amidation transformation. The methods include the successive oxidation-amidation of benzhydrylsulfanyl carboxylic acid to produce racemic and enantiomers of modafinil using at least one microorganism of yeast, bacteria, or fungus. Also disclosed are pharmaceutical compositions of racemic and enantiomers of modafinil along with their use in the treatment of diseases, including attention deficit hyperactivity disorder and drug addiction.

标题 :Enzymatic synthesis of soluble glucan fiber
发明人：DICOSIMO ROBERT; CHENG QIONG; ELIOT ANDREW C; OUWEHAND ARTHUR; PAYNE MARK S; YOU ZHENG
权利人:DU PONT
摘要:An enzymatically produced soluble α-glucan fiber composition is provided suitable for use as a digestion resistant fiber in food and feed applications. The soluble α-glucan fiber composition can be blended with one or more additional food ingredients to produce fiber-containing compositions. Methods for the production and use of compositions comprising the soluble α-glucan fiber are also provided.
