标 题:Polymerization process for the synthesis of vinyl aromatic polymers with a controlled structure
发明人:GHELFI FRANCO; FERRANDO ANGELO; LONGO ALDO; BUFFAGNI MIRKO
权利人:VERSALIS SPA
摘要:The present invention relates to a polymerization process for the synthesis of vinyl aromatic polymers, in which the sequence of monomers in the chain and the linear, branched soluble, or crosslinked insoluble structure, with reactive or different polarity functions, are controlled. Said process comprises the step of polymerizing vinyl aromatic monomers by means of an Atom Transfer Radical Polymerization (ATRP) reaction with an Activator ReGenerated by Electron Transfer (ARGET), the reaction being carried out at a temperature comprised between 25° C. and 110° C. in an inert gas atmosphere in the presence of a complex catalyst containing a cupric halide and a multidentate amine ligand, feeding to the reaction an organic initiator having two geminal halogens, an alkali metal (bi)carbonate, a solvent pair of an aliphatic alcohol and an acetic ester of the same aliphatic alcohol and possibly ascorbic acid, provided that no initiator is used with three or more active halogens, or polyvinyl monomers or inimers.

发明人:YANG DAVID J; YU DONGFANG; THOMPSON ANDREW S
权利人:YANG DAVID J; YU DONGFANG; THOMPSON ANDREW S; CEIL POINT LLC; UNIV TEXAS
摘要:Novel methods of synthesis of chelator-targeting ligand conjugates, compositions comprising such conjugates, and therapeutic and diagnostic applications of such conjugates are disclosed. The compositions include chelator-targeting ligand conjugates optionally chelated to one or more metal ions. Methods of synthesizing these compositions in high purity are also presented. Also disclosed are methods of imaging, treating and diagnosing disease in a subject using these novel compositions, such as methods of imaging a tumor within a subject and methods of diagnosing myocardial ischemia.

摘要:The invention describes novel nitrosated and/or nitrosylated pyruvate compounds and pharmaceutically acceptable salts thereof, and novel compositions comprising at least one nitrosated and/or nitrosylated pyruvate compound, and, optionally, at least one compound that donates, transfers or releases nitric oxide, stimulates endogenous synthesis of nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor or is a substrate for nitric oxide synthase, and/or at least one therapeutic agent. The invention also provides novel compositions comprising at least one pyruvate compound and at least one compound that donates, transfers or releases nitric oxide, elevates endogenous levels of endothelium-derived relaxing factor, stimulates endogenous synthesis of nitric oxide or is a substrate for nitric oxide synthase and/or at least one therapeutic agent. The invention also provides novel kits comprising at least one pyruvate compound, that is optionally nitrosated and/or nitrosylated, and, optionally, at least one nitric oxide donor and/or at least one therapeutic agent. The invention also provides methods for treating diseases resulting from oxidative stress, diabetes, reperfusion injury following ischemia, preservation of tissues, organs, organ parts and/or limbs.

标 题 :Synthesis of backbone modified morpholino oligonucleotides and chimeras using phosphoramidite chemistry
发明人:CARUTHERS MARVIN; PAUL SIBASISH
权利人:UNIV COLORADO REGENTS; UNIV COLORADO REGENTS
摘要:Amine substituted morpholino oligonucleotides, other than the classical N,N-dimethylamino PMO analogue, and methods of efficiently synthesizing these oligonucleotides with high yield are provided. Morpholino oligonucleotides having thiophosphoramidate, phosphoramidate, and alkyl phosphoramidate linkers. Chimeras containing unmodified DNA/RNA and other analogs of DNA/RNA can be prepared. These oligonucleotides form duplexes with complementary DNA or RNA that are more stable than natural DNA or DNA/RNA complexes, are active with RNAse H1, and may be transfected into cells using standard lipid reagents. These analogues are therefore useful for numerous applications.
