New techniques, such as crystallography and three-dimensional modeling, can be used to assist the development of selective targeted agents for cancer treatment. In this Review, Pierotti and colleagues discuss the molecular features of KIT and PDGFRA receptor tyrosine kinases, which are druggable targets in gastrointestinal stromal tumors. The authors focus on the major challenge in kinase drug discovery—the emergence of resistance—and discuss techniques for predicting and preventing this adverse event.
