Description

Application

Tyrphostin AG 1478 has been used as epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor to study its effect on desmoid cell mobility in boyden chamber motility assays. It has also been used to inhibit phosphorylation of c-Met by exogenous transforming growth factor α in epidermoid carcinoma cell line A431.

Biochem/physiol Actions

Tyrphostin AG 1478 is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor. It contributes to the development of hypomagnesemia and cardiac dysfunction in rats. Tyrphostin AG 1478 acts as a potential therapeutic agent for breast cancer.

Preparation Note

Tyrphostin AG 1478 dissolves in DMSO:MeOH (1:1) at 10 mg/ml to yield a clear, colorless solution. It is also soluble in methylene chloride (10 mg/ml), ethanol (10 mg/ml) and 0.1 N HCl (less than 0.4 mg/ml). However, it is insoluble in water, 2-hydroxypropyl-β-cyclodextrin, and 0.1 N NaOH.

The effects of a new epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor, tyrphostin AG 1478, were tested on three related human glioma cell lines: U87MG, which expressed endogenous wild-type (wt) EGFR, and two retrovirally infected U87MG cell populations which
