Application

Tyrphostin 1 has been used to study its effect on the increase of transgene expression in HeLa and NIH3T3 cells.

Biochem/physiol Actions

Tyrphostin 1 is a small molecule inhibitor of epidermal growth factor (EGF) receptor kinase function. This molecule associates with the substrate subsite of the protein tyrosine kinase (PTK) domain. Tyrphostin 1 is also known to block EGF-dependent receptor autophosphorylation,. Furthermore, studies have reported that tyrphostin 1 can block Ca2+ channels and inhibit growth in vascular smooth muscle cells,.
EGFR tyrosine kinase inhibitor.
