Kit a type III receptor tyrosine kinase, along with its ligand the stem cell factor, play a critical role in normal cell growth, differentiation, development and survival. Ligand independent activation of kit (dysregulated kit function) has been found to be an important component of oncogenesis in a large number of neoplastic disorders such as systemic mastocytosis, gastro intestinal stromal tumors, germ cell tumors, acute myelogenous leukemia with the disruption of the core binding factor, amongst others. The identification of small molecule inhibitors with activity against Kit, has offered a wider and more effective range of therapeutic options in the treatment of these neoplastic processes. Novel tyrosine kinase inhibitors such as imatinib, nilotinib and dasatinib, have been found to be effective in the management of various subtypes of systemic mastocytosis and gastrointestinal stromal tumors. Non-tyrosine kinase inhibitors like rapamycin, 17-AAG and IMD- 0354 have been added to the therapeutic armamentarium, with the hope that combination therapy might have a synergistic effect, or prevent/delay the development of drug resistance.
