gefitinib impurity 1

Gefitinib impurity 1 is a compound derived from Gefitinib, a potent and selective EGFR tyrosine kinase inhibitor (IC 50 = 33 nM). This orally active compound selectively inhibits tumor cell growth stimulated by EGF (IC 50 = 54 nM) and inhibits EGFR autophosphorylation induced by EGF in tumor cells. Additionally, Gefitinib induces autophagy and exhibits antitumor activity.
