摘要:The present invention relates to an improved process for the synthesis of glucagon-like-peptide-1 (GLP-1) and its analogs by using combination of solid and solution phase synthesis of Fmoc protected amino acids in a sequential manner, optionally incorporating Boc protected dipeptide for unnatural amino acid in the Sequence of GLP-1, cleaving GLP-1 sequence from the resin followed by purification; attaching side-chain to the desired amino acid in the solution phase to synthesize desired GLP-1 analog, purifying it to Semaglutide. Temperature gradient is applied during initial coupling of amino acids to facilitate completion of difficult coupling reactions.

标题 :Preparation of high purity phenothiazine N-alkylsulfonates and their use in chemiluminescent assays for the measurement of peroxidase activity
发明人：DELLA CIANA LEOPOLDO
权利人:CYANAGEN SRL
摘要:A process is described for preparing, efficiently and with a high degree of purity N-alkylsulfonates of phenothiazine. The process consists in (a) the preparation of the phenothiazine anion, and (b) the reaction of said anion with cyclic alkyl sulfonates, such as 1,3-propane sultone and 1,4-butane sultone. This process is simpler, more direct, and more efficient than the procedures currently used for the synthesis of N-alkylsulfonates derivatives of phenothiazine. In addition, the products obtained with this process are far more pure than those obtained through current procedures and therefore ideal for bioanalytical applications that require high sensitivity, such as assays based on the measurement of peroxidase activity using chemiluminescence.

摘要:The invention relates to a process for the anionic polymerization and copolymerization of vinyl, dienic and heterocyclic monomers. According to the invention, the process consists in carrying out the reaction in the presence of an initiator consisting of a molecular combination of an alkali metal amide and the salt of the same alkali metal with at least one hydroxylic compound and in the absence of solvent. The initiator can be prepared by intimately mixing its constituents or in the presence of a solvent of low polarity which is subsequently evaporated off, or in situ in the monomer. Application to the synthesis of special or widely used polymers and copolymers.

摘要:A process for the synthesis of novel compounds is described comprising reacting tetrachloroethylene with substances containing active methylene group in the presence of free radical initiators. Also, a process for grafting tetrachloroethylene is described comprising reacting these compounds with polymers containing active methylene group in the presence of free radical initiators. Furthermore, a method of conducting such reactions to high conversion is described, comprising conducting the reactions in the reflux condensate. The present invention provides a novel and high yield route for heretofore unobtainable materials.
