Targeting the dimerization of epidermal growth factor receptors with small-molecule inhibitors.

ABSTRACT: The epidermal growth factor (EGF) receptor is a receptor tyrosine kinase involved in the control of cell proliferation, and its overexpression is strongly associated with a variety of aggressive cancers. For example, 70-80% of metaplastic (cancer cells of mixed type) breast carcinomas overexpress EGF receptors. In addition, the EGF receptor is a highly significant contributor to common brain tumors (glioblastoma multiforme), both in initiation and progression (Huang P.H., Xu A.M., White F.M. (2009) Oncogenic EGFR signaling networks in glioma. Sci Signal;2:re6.). Brain metastases, an unmet medical need, are also common in metastatic cancer associated with overexpression of EGF receptors. Formation of EGF receptor homodimers is essential for kinase activation and was the basis for exploring
