标 题:Synthesis of bis trialkylsilylamide and resulting composition
发明人：FORAT GERARD
权利人:RHODIA CHIMIE SA
摘要:The invention concerns the synthesis of bis trialkylsilylamide which consists in: subjecting the amide to the action of a trialkylsilyl halide on an amide bearing a Rf group in the presence of a base whose halide, or halohydrate is insoluble in the medium and in the presence of a covalent and non-hydrophilic solvent. The invention is applicable to organic synthesis.

发明人：FORAT GERARD; MAS JEAN-MANUEL; SAINT-JALMES LAURENT
权利人:RHONE POULENC CHIMIE
摘要:The invention relates to a reagent which is useful for the synthesis of oxysulphide-containing fluorine-containing organic derivatives by reacting with an oxide of sulphur, especially sulphur dioxide, characterized in that it comprises: a) a fluorocarboxylic acid of formula Ew-CF2-COOH where Ew is an electron-withdrawing group or atom which is at least partially salified by an organic or inorganic cation, and b) an aprotic polar 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. This reagent can be used by heating in order to form fluorine-containing sulphinic or sulphonic acids.

发明人：BRAUN MAX; BRAUKMUELLER SASKIA
权利人:SOLVAY FLUOR & DERIVATE
摘要:3-aminocrotonate compounds, e.g. diesters, which are substituted on the C-4 atom by at least two chlorine and/or fluorine atoms, are produced by reacting corresponding acetoacetate compounds with ammonia and primary and secondary amines while simultaneously or subsequently eliminating water. The reaction is carried out in the presence of onium salts formed from primary or secondary amines and carboxylic acids. Preferably, two phases are formed; one phase containing the crotonate compound product with a good degree of purity and the other phase containing the onium salt and water.

标题 :Methods of modulating functions of polypeptide GalNAc-transferases and of screening test substances to find agents herefor, pharmaceutical compositions comprising such agents and the use of such agents for preparing medicaments

摘要:Attachment of O-glycans to proteins is controlled by a large family of homologous polypeptide GalNAc-transferases. Polypeptide GalNAc-transferases contain a C-terminal sequence with similarity to lectins. This invention discloses that the putative lectin domains of GalNAc-transferase isoforms, GalNAc-T4, -T7, -T2, and -T3, are functional and recognize carbohydrates, glycopeptides, and peptides and discloses the lectin domains of GalNAc-T1-T16. These lectin domains have different binding specificities and modulate the functions of GalNAc-transferase isoforms differently. Novel methods for identification of inhibitors or modulators of binding activities mediated by lectin domains of polypeptide GalNAc-transferases are disclosed. Direct binding activity of GalNAc-transferase lectins has been demonstrated for the first time and methods to measure lectin mediated binding of isolated lectins or enzymes with lectin domains are disclosed. The present invention specifically discloses a novel selective inhibitor of polypeptide GalNAc-transferase lectin domains, which provides a major advancement in that this inhibitor and related inhibitors sharing common characteristics of activity bind lectin domains without serving as acceptor substrate for glycosyltransferases involved in synthesis of O-glycans. This inhibitor is represented by the β-anomeric configuration of GalNAc-benzyl, GalNAcβ-benzyl. Methods for inhibiting intracellular transport, cell surface expression, and secretion of mucins and O-glycosylated glycoproteins without affecting O-glycosylation processing are disclosed using the novel selective inhibitor identified.
