标 题 :Synthesis of anti-inflammatory compounds, and novel trisaccharides useful in the synthesis of anti-inflammatory compounds
发明人：LAINE ROGER A
权利人:UNIV LOUISIANA STATE; AGRICULTURAL AND MECHANICAL CO
摘要:Anti-inflammatory compounds are useful, for example, in treating arthritis and heart attack patients. Novel oligosaccharides useful in the rapid synthesis of certain anti-inflammatory compounds are disclosed, as is a rapid method of synthesizing the oligosaccharides. Low pH can loosen the acceptor specificity of galactosyltransferase (lactose synthase: EC 2.4.1.22), allowing the rapid synthesis of novel oligosaccharides. The disaccharides cellobiose (β1→4), laminaribiose (β1→3), gentiobiose (β1→6) and maltose (α1→4) acted as acceptors for lactose synthase under low pH conditions. From these four acceptors, the following four novel trisaccharides were synthesized: Gal p (β1→4)Glc p (β1→3) -Glc, Gal p (β1→4)Glc p (β1→4)-Glc, Gal p (β1→4)Glc p (β1→6)-Glc and Gal p (β1→4)Glc p (α1→4)Glc. These trisaccharides, and other oligosaccharides, may be synthesized in a few days with the disclosed technique, as opposed to the several months which would likely have been required with more traditional organic synthetic methods. These trisaccharides may be used as intermediates in the rapid synthesis of anti-inflammatory compounds.

摘要:Described are novel processes for the synthesis triflated sugars. These sugars are useful for the production of compounds, such as D-1-deoxynojirimycin (DNJ) and D-1-deoxygalactonojirimycin (DGJ). In particular, described is a multi-kilogram scale stabilization method for the synthesis of imino sugars.

摘要:The present invention relates to a recombinant process for the production of truncated or mutated dextransucrases while conserving the enzymatic activity or their specificity in the synthesis of the α-1,6 bonds. The present invention relates to nucleic acid sequences of truncated or mutated dextransucrases, vectors containing the nucleic acid sequences and host cells transformed by sequences encoding truncated or mutated dextransucrases. In another aspect, the invention concerns a method for producing, in a recombinant manner, truncated or mutated dextransucrases which conserve their enzymatic activity or which conserve their specificity in the synthesis of α-1,6 bonds and can produce, from saccharose, dextrans with high molar mass and modified rheological properties compared with the properties of dextran obtained with the native enzyme and isomalto-oligosaccharides with a controlled molar mass and dextrans. The dextrans and isomalto-oligosaccharides of the invention can be used namely as texturing agents or as prebiotics.

权利人:UNIV CALIFORNIA
摘要:Glycosylated polyamines comprising of mono- or oligo-saccharides that are glycosidically linked to an aliphatic polyamine, and pharmaceutically acceptable salts, prodrugs and derivatives thereof are provided. An exemplary glycosylated polyamine has the following structure: n Glycosylated polyamines, their pharmaceutically acceptable salts, prodrugs and derivatives are useful, for example, as anticancer compounds for the treatment of a variety of cancers. Methods for synthesis of glycosylated polyamines are disclosed. In addition, metal complexes of glycosylated polyamines, the preparation of such metal complexes, analytical methods using the metal complexes are provided. Methods for detecting equatorial and axial conformation of a group other than hydrogen at the C2 position of a saccharide molecule are also provided. The compounds of the invention can be used as anti-cancer agents (e.g., against breast, ovarian, colon or renal cancers). Furthermore, the compounds of the invention are ligands for the estrogen receptor and thus can be used to modulate estrogen receptor activity, for example to treat or prevent breast cancer, to treat or prevent osteoporosis or to reduce the risk of cardiovascular disease in a subject (e.g., a postmenopausal female subject).
