4、04) effectively inhibits the in vitro kinase activity of wild-type EGFR (IC50=6 nM)withsimilar efficacy. Dacomitinib also effectively inhibits wild-type ERBB2 with IC50 of 45.7 nM. In H441, an IC50is reached with Dacomitinib but only at a very high concentration (4 M) and likely reflects off-target

5、effects.In cell lines wild-type for both EGFR and K-ras (H322, H1819, and Calu-3), Gefitinib and Dacomitinib botheffectively inhibit growth of H1819 and Calu-3 cells but not of H322 cells. Dacomitinib is a pan-ERBB inhibitorand most EGFR mutant cell lines express multiple ERBB family members, the ef

6、fects on EGFRphosphorylation could potentially be indirect. Dacomitinib inhibits EGFR phosphorylation in all of the differentEGFR T790M proteins whereas Gefitinib is ineffective even at 10 M. In the NIH3T3 cells, phosphorylation ofEGFR L858R/T790M is completely inhibited by 1 nM Dacomitinib, whereas

7、 100 nM or greater is required toinhibit EGFR WT/T790M or Del/T790M 1. The HER2-amplified cell lines are most sensitive to growthinhibition by Dacomitinib (IC50 2.體內(nèi)研究 To evaluate the efficacy of Dacomitinib, xenografts in nu/nu mice are generated using HCC827 GFP andHCC827 Del/T790M cells and treat

8、ed the mice with Dacomitinib. Dacomitinib (10 mg/kg/d by daily oralgavage) effectively inhibits the growth of HCC827 GFP xenografts. In contrast, HCC827 Del/T790Mxenografts are resistant to Gefitinib, whereas Dacomitinib treatment is substantially more effective atinhibiting growth of this xenograft

9、 model 1.PROTOCOLKinase Assay 1 The catalytic domains of ERBB1, ERBB2, and ERBB4 tagged with glutathione S-transferase are expressedin insect cells and purified. ELISA-based enzyme assays and IC50 determinations for ERBB1, ERBB2, andERBB4 are performed. Enzyme assays and IC50 determinations for all
