  • New immunoeffector compounds
    Publication number: 20070004914
    Abstract: This invention provides compounds containing a 2-deoxy-2-amino-?-D-glucopyranose (glucosamine)glycosidically linked to an cyclic aminoalkyl (aglycon) group. The invention further provides methods for inducing an immune response using the compounds of the present invention in the presence or absence of an antigen. In addition, methods for treating disease with the compounds of the present invention with or without an antigen are also provided in this invention.

  • Inhibitors of human phosphatidylinositol 3-kinase delta
    Publication number: 20050261317
    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 PI3K5, 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.
