  • Publication number: 20160257671
    Abstract: Compounds of formula (I): where n, R1, R4a, R4b, R5, R7 and R8 are defined herein, or pharmaceutically acceptable salts thereof, are described herein. The disclosed 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 formula (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.
    Type: Application

  • Patent number: 7459479
    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.
    Type: Grant
