Certain substituted imidazo[1,2-a]pyrazines, as modulators of kinase activity

Abstract

Certain substituted imidazo[1,2-a]pyrazines and the pharmaceutically acceptable salts thereof, are provided herein. Pharmaceutical compositions containing one or more compound of Formula I, or a pharmaceutically acceptable salt of such compounds, and one or more pharmaceutically acceptable carriers, excipients, or diluents, are also provided herein. Methods of treating patients suffering from certain diseases and disorders responsive to EphB4 kinase modulation, which comprise administering to such patients an amount of a compound of Formula I effective to reduce signs or symptoms of the disease or disorder are disclosed. Methods of treatment include administering a compound of Formula I as a single active agent or administering a compound of Formula I in combination with one or more other therapeutic agents. A method for determining the presence or absence of an angiogenic kinase in a sample comprising contacting the sample with a compound of Formula I under conditions that permit detection of activity of the angiogenic kinase, detecting a level of the activity of the angiogenic kinase, and therefrom determining the presence or absence of the angiogenic kinase in the sample.
