Summary for Patent: 8,138,195

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

Non-Orange Book US Patents Family Members for Patent 8,138,195

For Orange Book-listed patents (shown in the main table above) generic applications must certify that the listed patents are expired, invalid, or will not be infringed by generic entry.

The non-Orange Book patents listed below do not require formal certifications, so they do not automatically impede generic entry. Instead, they represent potential opportunities for branded firms to block generic entry through patent infringment challenges.
