General description

A cell-permeable and irreversible inhibitor of EGF-receptor (EGFR) kinase activity in vivo (IC50 = 250-490 pM) as well as EGF-stimulated autophosphorylation of tyrosine residues in the EGFR in vivo (IC50 = 5 nM). Blocks EGF-mediated growth in A431 cells. Inhibits proliferation of EGFR or c-ErbB2 expressing cells (IC50 = 31-125 nM) by covalently binding to the EGFR.
A cell-permeable and irreversible inhibitor of EGF-stimulated autophosphorylation of tyrosine residues in the epidermal growth factor receptor (EGFR) in vivo (IC50 = 250-490 pM) and blocks EGF-mediated growth. Also inhibits proliferation of cells that overexpress EGFR or c-Erb-2 (IC50 = 31-125 nM) by covalently binding to EGFR.

Acantholysis in pemphigus vulgaris (PV) may be triggered by desmoglein (Dsg) and non-Dsg autoantibodies. The autoantibody profile of each patient results in distinct intracellular signalling patterns. Based on our previous findings, we aimed to elucidate whether PV acantholysis in a
