4-(3-Chloro-4-fluorophenylamino)-7-methoxy-6-[3-(4-morpholinyl)propoxy]quinazoline dihydrochloride Chemical Properties,Usage,Production
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].
in vivo
Gefitinib dihydrochloride (Oral administration, 75 mg/kg/d, 21 days) inhibits the M2-like polarization of macrophages in LLC mice metastasis model[3].
Gefitinib dihydrochloride (Oral administration, 75 mg/kg for the initial week, daily for 5 consecutive days per week) eliminates phosphorylation of HER2 and HER3 and signaling through MAPK and Akt in lobular hyperplasias and carcinomas, increases MAPK activity and cytokine production in splenocytes and lymph nodes[5].
Gefitinib dihydrochloride (Oral gavage, 150 mg/kg, daily) enhances the anti-tumor effect of Cisplatin in H358R xenograft[7].
| Animal Model: | LLC mice metastasis model[3] |
| Dosage: | 75 mg/kg/d, for 21 days. |
| Administration: | Oral administration |
| Result: | Reduced the number of lung metastasis nodules, down-regulated the expression of M2 marker genes and the percentages CD206+ and CD68+ macrophages in tumor tissues. |
| Animal Model: | BALB-NeuT transgenic mouse model[5] |
| Dosage: | 75 mg/kg for the initial week, and increased by 15 mg/kg every other week, daily for 5 consecutive days per week, followed by 2 days without treatment and repeated for 8–9 weeks. |
| Administration: | Oral administration |
| Result: | Reduced tumor multiplicity from 9.6 to 0.58 (83%), and reduced the number and size of lobules and lobular nodules in treated mice. |
