  • Patent number: 8101605
    Abstract: Compounds of structure (I): including stereoisomers and pharmaceutically acceptable salts thereof, wherein X, R1, R2, R3, R4, R5, R6 and R7 are as defined herein. Such compounds have activity as SHIP1 modulators, and thus may be used to treat any of a variety of diseases, disorders or conditions that would benefit from SHIP1 modulation. Compositions comprising a compound of structure (I) in combination with a pharmaceutically acceptable carrier or diluent are also disclosed, as are methods of SHIP1 modulation by administration of such compounds to an animal in need thereof.

  • Publication number: 20070208181
    Abstract: The present invention is directed to a method for reducing the emetogenic effects of PDE inhibitors, and more particularly is directed to compounds having PDE4 inhibition activity with little or no emetogenic side-effects, and chemical methods including benzylation for preparing such compounds. A benzyl group may be attached to either a carbon or nitrogen atom of a PDE4 inhibitor. Suitable benzylation chemistry is to extract a hydrogen from a PDE4 inhibitor, preferably with a base, and then react the resulting nucleophilic PDE4 inhibitor with a benzylating agent, e.g., benzyl bromide or a derivative thereof.

  • Patent number: 7078194
    Abstract: Mutant glycosidase enzymes are formed in which the normal nucleophilic amino acid within the active site has been changed to a nonnucleophilic amino acid. These enzymes cannot hydrolyze disaccharide products, but which can still form them. Using this enzyme, oligosaccharides are synthesized by preparing a mixture of an &agr;glycosyl fluoride and a glycoside acceptor molecule; enzymatically coupling the &agr.glycosyl fluoride to the glycoside acceptor molecule to form a glycosyl glycoside product using the mutant glycosidase enzyme; and recovering the glycosyl glycoside product. Particular enzymes include a mutant form of Agrobacterium &bgr.Glucosidase in which the normal glutamic acid residue at position 358 is replaced with an alanine residue.

  • Patent number: 6284494
    Abstract: Mutant glycosidase enzymes are formed in which the normal nucleophilic amino acid within the active site has been changed to a non-nucleophilic amino acid. These enzymes cannot hydrolyze disaccharide products, but which can still form them. Using this enzyme, oligosaccharides are synthesized by preparing a mixture of an &agr;-glycosyl fluoride and a glycoside acceptor molecule; enzymatically coupling the &agr;-glycosyl fluoride to the glycoside acceptor molecule to form a glycosyl glycoside product using the mutant glycosidase enzyme; and recovering the glycosyl glycoside product. Particular enzymes include a mutant form of Agrobacterium &bgr;-Glucosidase in which the normal glutamic acid residue at position 358 is replaced with an alanine residue.

  • Patent number: 5716812
    Abstract: Mutant glycosidase enzymes are formed in which the normal nucleophilic amino acid within the active site has been changed to a non-nucleophilic amino acid. These enzymes cannot hydrolyze disaccharide products, but can still form them. Using this enzyme, oligosaccharides are synthesized by preparing a mixture of an .alpha.-glycosyl fluoride and a glycoside acceptor molecule; enzymatically coupling the .alpha.-glycosyl fluoride to the glycoside acceptor molecule to form a glycosyl glycoside product using the mutant glycosidase enzyme; and recovering the glycosyl glycoside product. Particular enzymes include a mutant form of Agrobacterium .beta.-Glucosidase in which the normal glutamic acid residue at position 358 is replaced with an alanine residue.
