标题:侧链对叔胺官能化多肽的ph和热响应性的影响
摘要:侧链上的ph的结构影响的系统调查和叔胺官能化聚(热响应性升-谷氨酸)s(ta-的pgs)中的溶液中进行.通过铜(i)催化的叠氮基叔胺与聚(γ-炔丙基-L-谷氨酸)(pplg)的叠氮化物-炔烃环加成点击反应有效合成了ta-Pgs聚合物.进行了比浊法测量,以表征ta-Pg在水溶液中的ph和温度诱导的相变,这表明该性质对氮的结构依赖性取代基团和1,2,3-三唑环与侧链中叔胺基团之间的"连接基".详细地讲,Ta-Pg的ph响应特性基本上由侧链中n-取代基团的疏水性决定,Ph转变点(ph T)随着n-取代基团疏水性的增加而降低,而ta Pg的温度响应性受n取代基或"连接基"的影响.具有中等n取代胺基(例如dea,Pr和pd)或支链"连接子"(例如iso-丙烯和2-甲基丙烯基)更可能表达因ph值变化而调整的lcst型相变.这项研究揭示的这些结构-属性关系将有助于开发ta-Pg在智能药物输送系统中的应用.©2013

标题 :Synthesis of 2-alkyl amino acids
发明人:CHORGHADE MUKUND S; GURJAR MUKUND K; MOHAPATRA DEBENDRA K
权利人:GENZYME CORP
摘要:Non-natural amino acids such as 2-alkylated amino acids allow for the synthesis of a wider variety of peptidal and non-peptidal pharmaceutically active agents. A method of preparing a 2-alkyl amino acid involves a Michael-type addition of a nucleophile to a dialkyl 2-methylidenylpropan-1,3-dioate and the conversion of a ester moiety into an amino moiety. The present invention also discloses a method of preparing a class of iron chelating agents related to desferrithiocin, all of which contain a thiazoline ring. In this method, an aryl nitrile or imidate is condensed with cysteine, a 2-alkyl cysteine, or a cysteine ester.

标 题 :Solvent-free synthesis of ethereally substituted blocked monosaccharides and the selective hydrolysis thereof
发明人:ARORA SUDERSHAN K
权利人:GREENWICH PHARMA
摘要:A solvent-free method for synthesizing an ethereally-substituted, blocked monosaccharide comprising the steps of: n 1) mixing, in the absence of solvent, a partially blocked monosaccharide unblocked at one position, an alkyl halide or a substituted alkyl halide, and an anhydrous alkali base; n 2) heating the mixture to a temperature sufficient to allow the mixture to react; n 3) maintaining the mixture at a suitable temperature for a time sufficient to form an ethereally-substituted blocked monosaccharide and drive off any water produced; n 4) removing any unreacted alkyl halide or substituted alkyl halide from the mixture; n 5) recovering the ethereally-substituted blocked monosaccharide product from the mixture; and, optionally, n 6) selectively hydrolyzing the ethereally-substituted blocked monosaccharide product to remove one or more of the acetal blocking groups.
