AG1478 (also known as Tyrphostin AG 1478 ) is a selective EGFR inhibitor, which induced cell cycle arrest in G1 phase, is developed as potential drug for nasopharyngeal carcinoma treatment. In addition was shown, that AG1478 effectively blocked the leiomyoma cell growth and is unaffected by the presence of physiological concentrations of progesterone and estradiol. The growth-arresting properties of AG1478, unaffected by ovarian steroidal hormones, identify it as a potential lead agent for the non-surgical management of uterine leiomyomas. Also was investigated the action of the combination AG1478 in combination with HGF tyrosine kinase inhibitors on non-small cell lung cancer (NSCLC) cells, and was suggested, that these combinations of drugs could be potentially used for treatment of NSCLC.

Sample Use Guides

xenografted mice: treated with saline as placebo, 0.4 mg AG1478 i.p.
Route of Administration: Intravenous
AG1478 (1-1000 nM) significantly inhibited both LPS-induced and TNF-α-induced secretion of MUC5AC and IL-8 from cultured NCI-H292 cells in a dose-dependent manner. The expression of MUC5AC and IL-8 messenger RNAs was also significantly inhibited. Intranasal instillation of AG1478 one hour after intranasal LPS instillation significantly inhibited LPS-induced goblet cell metaplasia, mucus production, and neutrophil infiltration in rat nasal epithelium, as did intraperitoneal injection of AG1478 one hour before LPS instillation.
