4-(3-Chloro-4-fluorophenylamino)-7-methoxy-6-[3-(4-morpholinyl)propoxy]quinazoline dihydrochloride

Uses

Gefitinib (ZD 1839) dihydrochloride is a potent, selective and orally active EGFR tyrosine kinase inhibitor with an IC50 of 33 nM. Gefitinib dihydrochloride selectively inhibits EGF-stimulated tumor cell growth (IC50 of 54 nM) and blocks EGF-stimulated EGFR autophosphorylation in tumor cells. Gefitinib dihydrochloride also induces autophagy and cell apoptosis, which can be used for cancer related research, such as Lung cancer and breast cancer [1][2][5].
