Background

Tyrphostin AG 1478 is a tyrosine kinase inhibitor specifically selective to EGFR (ErbB1), with an IC₅₀ of about 3 nM in vitro (1,2). Treatment of cell with 50-150 nM of AG 1478 can substantially block EGFR activiation in vivo (3). In addition to EGFR, AG 1478 also inhibits ErbB4 activation induced by radiation in cancer cells (4). Testing of AG 1478 alone or in combination with other treatments to assess anti-tumor and anti-fibrotic effectiveness has yielded promising results (5-8).
