Certain substituted diphenyl ureas, as modulators of kinase activity

Abstract

Certain chemical entities chosen from compounds of Formula 1 and pharmaceutically acceptable salts, solvates, crystal forms, chelates, non-covalent complexes, prodrugs, and mixtures thereof, are provided herein. Pharmaceutical compositions comprising at least one chemical entity and one or more pharmaceutically acceptable vehicle 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. A method for determining the presence or absence of an angiogenic kinase in a sample comprising contacting the sample with at least one chemical entity 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.
