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.
Selective inhibitor of epidermal growth factor receptor protein
