title: Second-generation kinase inhibitors.
abstract: An increasing number of kinase inhibitor candidates are entering clinical development, representing an important change in the pharmaceutical industry; notably, the development of small-molecule kinase inhibitors for signal transduction therapies. Today, kinase inhibitors garner substantial attention in cancer research. Over the last few years, three distinct small-molecule kinase inhibitors reached the market for treatment of chronic myeloid leukaemia, gastrointestinal stromal tumours, and non-small cell lung cancers. These three drugs, imatinib, gefitinib and erlotinib, act on a distinct subset of dysregulated, and often cancer-relevant kinases. Imatinib, gefitinib and erlotinib are considered the front-runners of targeted kinase inhibitor drugs. The entire research field gains tremendous insights through the ongoing research and clinical trials with these three drugs and with fast following first-generation kinase inhibitors, many of which are in different phases of clinical development. In addition, novel chemogenomic and chemoproteomic technologies are emanating from the current kinase research area, focussing efforts on the generation of spectrum-selective inhibitors for anticancer therapies as opposed to the monospecific inhibitors for the remaining therapeutic areas.
