Datasheet of PD158780
Description:. PD158780 is a very potent inhibitor of EGFR with IC50 of 0.08 nM; pan-specific antagonist of ErbB receptor. in vitro: PD158780 potently inhibited the LPA-stimulated MAP kinase kinase 1/2 (MKK1/2) activation and EGF receptor tyrosine phosphorylation in HeLa cells, while it had no detectable effect on c-Src kinase activity. PD158780 also inhibited LPA-induced MKK1/2 activation and DNA synthesis in NIH 3T3 cells. Furthermore, we compared LPA-stimulated MKK1/2 and MAP kinase activation, transcriptional activity of the c-fos promoter, and DNA synthesis in B82L cells, which lack endogenous EGF receptor, and B82L cells expressing kinase-defective or wild-type human EGF receptor. in vivo: NRG-1beta dramatically increases gamma oscillation power in hippocampal slices from both rats (2062 +/- 496%) and mice (710 +/- 299%). These effects of NRG-1beta are blocked by PD158780, a pan-specific antagonist of ErbB receptors, and are mediated specifically via ErbB4 receptors, because mice harboring a targeted mutation of ErbB4 do not respond to NRG-1.
