NCIt definition : A selective thiophene-derived tyrosine kinase inhibitor with potential antineoplastic
activity. Tyrosine kinase inhibitor OSI-930 inhibits stem cell factor receptor (c-Kit)
and the vascular endothelial growth factor receptor 2 (VEGFR2), which may result in
the inhibition of both tumor cell proliferation and tumor angiogenesis. Both c-Kit
and VEGFR2 are overexpressed in a variety of cancers.;
