Application

Tyrphostin AG 879 (AG879) has been used for studying its effect on ErbB2 receptor phosphorylation in A431 cells. This study reported that AG879 at 10 muM can cause 15% inhibition of receptor phosphorylation1. AG879 has also been used as a neurotrophic tyrosine kinase receptor inhibitor to study the disruption of Sertoli cell aggregation2.

Biochem/physiol Actions

Tyrphostin AG 879 is known to block RAF-1 and Her-2 expression and exhibit anticancer functions in breast cancer cells3. Furthermore, AG879 is known to block ETK1-PAK1 interactions and the growth of RAS-induced sarcomas in nude mice4.
Inhibits the tyrosine kinase activity of the nerve growth factor receptor (TrkA; pp140trk) and heregulin receptor erbB-2 (HER-2).
