Tyrphostin AG 99 is a potent, cell-permeable and reversible inhibitor of EGFR and EGF-dependent cell proliferation.

Epidermal growth factor receptor (EGFR) kinase inhibitor (IC 50 = 10 μ M) that is selective over insulin receptor kinase. Blocks tyrosine phosphorylation of p145 met and promotes cell death of normal and cancer cells via activation of caspase-like proteases in vitro .
