Abstract:
Disclosed are novel α-galactosylceramide derivatives, pharmaceutically acceptable salts thereof, preparation methods thereof, and pharmaceutical compositions for use in an immune adjuvant containing the same as an active ingredient. The derivatives, in which the amide moiety of α-GalCer is bioisosterically replaced with a triazole moiety, direct cytokine secretion toward IL-4 rather than IFN-γand thus can be used as a therapeutic for autoimmune diseases regulated by IL-4, such as type 1 diabetes and multiple sclerosis.
Abstract:
A novel ligand conjugate which is effectively utilizable for analyzing a function of a protein; a ligand-supporting object; and a method of analyzing a protein. The ligand conjugate has a structure which comprises: a linker compound having a structure represented by the following General Formula (1): (wherein n and p each is an integer of 0 to 6) in which X is a structure comprising one, two, or three hydrocarbon derivative chains which have an aromatic amino group at the end and may have a carbon-nitrogen bond in the main chain, Y is a hydro-carbon structure containing one or more sulfur atoms, and Z is a straight-chain structure comprising a carbon-carbon bond or carbon-oxygen bond; and a sugar which has a reducing end and is bonded to the linker compound through the aromatic amino group.
Abstract:
A process for isolating rhamnolipids is provided. The process includes providing an aqueous medium containing at least one rhamnolipid and having a pH of less than 6. Next, the aqueous medium is brought into contact with at least one organic solvent to provide a multiphase system and then the aqueous phase is separated off. The pH is then increased to a value of 6 or more to provide a multiphase organic system. Next, a rhamnolipid-enriched organic phase is separated off. An optional step of further purifying the rhamnolipid may be performed.

Abstract:
In preparing a glycoside compound from (a) a furanose compound or pyranose compound, and (b) an alcohol compound, a process for preparing a glycoside compound in which glycosidic bond locates selectively trans form relative to C-2 hydroxyl group, the process comprising using a furanose compound wherein the hydroxyl at the 2-position may have a substituent protected with a group A, or a pyranose compound which may have a substituent wherein R2 and R3 are the same or different and are each alkyl having 1 to 4 carbon atoms or aryl having or not having a substituent, or R2 and R3 are combined to form alkylene having 2 to 4 carbon atoms (the alkylene may be substituted with alkyl having 1 to 4 carbon atoms, or may have intervening phenylene), and m and n are each an integer of 0 or 1.
Abstract:
The present invention relates to synthetic lipoteicoic acid (LTA) mimetics which are useful as vaccine components for therapy and/or prophylaxis of bacterial infection.
Abstract:
A method for preparing a precursor used to label hepatocyte receptors is revealed. The precursor contains a bifunctional structure including trisaccharide and DTPA ligand. During synthesis processes of the precursor, silica gel columns and Reverse phase-18 (RP-18) columns are used for purification. Thus both the purification times and cost of each purification are reduced. Moreover, use diethyl ether to facilitate precipitation of products and remove a part of coupling reagent. Removing the coupling reagent helps purification of products. Furthermore, Nα,Nα-bis(carboxymethyl)-L-lysine hydrate and benzyl chloroformate are coupled to form a trisaccharide skeleton so as to ensure the yield rate of trisaccharide structure.
