Introduction: Protein tyrosine kinase inhibitors are currently one of the most important classes of cancer drugs and one of the most impressive approaches of targeted cancer therapy. Aberrant activation of tyrosine kinase pathways is among the most dysregulated molecular pathways in human cancers; therefore, a large number of tyrosine kinases may serve as valuable molecular targets. To date, several inhibitors of tyrosine kinases have been approved and there are hundreds more compounds that are in various stages of development. Because of the deregulation in human malignancies, the ABL1, SRC, the epidermal growth factor receptor and the vascular endothelial growth factor receptor kinases are among the protein kinases that are considered as prime molecular targets for selective inhibition. Areas covered: This review focuses on most important small-molecule inhibitors that serve as a model for future development. They also provide a broad overview of some of the new approaches and challenges in the field. Expert opinion: With the exception of a few malignancies seemingly driven by a limited number of genetic lesions, current targeted therapeutic approaches have shown only limited efficacy in advanced cancers. Consequently, more sophisticated strategies, such as identification of pathogenic 'driver' mutations and optimization of personalized therapies are needed.
