Abstract: Certain imidazopyrazines and pharmaceutical compositions thereof are provided herein. Methods of treating patients suffering from certain diseases and disorders responsive to the inhibition of Syk activity, which comprises administering to such patients an amount of at least one chemical entity effective to reduce signs or symptoms of the disease or disorder are provided. Also provided are methods for determining the presence or absence of Syk kinase in a sample.

Abstract: Compounds of Formula I that inhibit Btk are described herein. Pharmaceutical compositions comprising at least one compound of Formula I, together with at least one pharmaceutically acceptable vehicle chosen from carriers, adjuvants, and excipients, are described. Methods of treating patients suffering from certain diseases responsive to inhibition of Btk activity and/or B-cell activity are described. Methods for determining the presence of Btk in a sample are described.

Abstract: Certain chemical entities chosen from compounds of Formula 1 and pharmaceutically acceptable salts, solvates, chelates, non-covalent complexes, and prodrugs thereof, are provided herein. Pharmaceutical compositions comprising at least one chemical entity and one or more pharmaceutically acceptable vehicles chosen from carriers, adjuvants, and excipients, are also provided herein. Methods of treating patients suffering from certain diseases and disorders responsive to angiogenic kinase modulation, which comprise administering to such patients an amount of at least one chemical entity effective to reduce signs or symptoms of the disease or disorder are disclosed. These diseases include cancer, including breast neoplasia, endometrial cancer, colon cancer, and neck squamous cell carcinoma. Methods of treatment include administering at least one chemical entity as a single active agent or administering such at least one chemical entity in combination with one or more other therapeutic agents.

Abstract: Pyridone and aza-pyridone compounds of Formula I are provided, including stereoisomers, tautomers, and pharmaceutically acceptable salts thereof, useful for inhibiting Btk kinase, and for treating immune disorders such as inflammation mediated by Btk kinase. Methods of using compounds of Formula I for in vitro, in situ, and in vivo diagnosis, and treatment of such disorders in mammalian cells, or associated pathological conditions, are disclosed.
