  • Publication number: 20140154772
    Abstract: Methods of inhibiting phosphatidylinositol 3-kinase delta isoform (PI3K?) activity, and methods of treating diseases, such as disorders of immunity and inflammation, in which PI3K? plays a role in leukocyte function are disclosed. Preferably, the methods employ active agents that selectively inhibit PI3K?, while not significantly inhibiting activity of other PI3K isoforms. Compounds are provided that inhibit PI3K? activity, including compounds that selectively inhibit PI3K? activity. Methods of using PI3K? inhibitory compounds to inhibit cancer cell growth or proliferation are also provided. Accordingly, the invention provides methods of using PI3K? inhibitory compounds to inhibit PI3K?-mediated processes in vitro and in vivo.

  • Patent number: 7541020
    Abstract: Aminoalkyl glucosaminide phosphate (AGP) compounds that are adjuvants and immunoeffectors are described and claimed. The compounds have a 2-deoxy-2-amino glucose in glycosidic linkage with an aminoalkyl (aglycon) group. Compounds are phosphorylated at the 4 or 6 carbon on the glucosaminide ring and comprise three 3-alkanoyloxyalkanoyl residues. The compounds augment antibody production in immunized animals as well as stimulate cytokine production and activate macrophages. Compositions and methods for using the compounds as adjuvants and immunoeffectors are also disclosed.
