NCIt definition : The dihydrochloride salt form of NRC-2694, an orally bioavailable, small-molecule
inhibitor of epidermal growth factor receptor (EGFR), with potential antineoplastic
activity. Upon oral administration, EGFR inhibitor NRC-2694 binds to and inhibits
EGFR, which prevents EGFR-mediated signaling and leads to cell death in EGFR-expressing
tumor cells. EGFR, a receptor tyrosine kinase mutated in many tumor cell types, plays
a key role in tumor cell proliferation and tumor vascularization.;
