S2185 Allitinib (AST-1306) Allitinib (AST-1306, AST-6) is a novel irreversible inhibitor of EGFR and ErbB2 with IC50 of 0.5 nM and 3 nM, also effective in mutation EGFR T790M/L858R, more potent to ErbB2-overexpressing cells, 3000-fold selective for ErbB family than other kinases. Pan ErbB4, IC50: 0.8 nM
S1011 Afatinib (BIBW2992) Afatinib (BIBW2992) inhibits EGFR/ErbB irreversibly in vitro with IC50 of 0.5, 0.4, 10, 14, 1 nM for EGFRwt, EGFR L858R , EGFR L858R/T790M ErbB2 (HER2) and ErbB4 (HER4), respectively. Afatinib induces autophagy. Pan ErbB4, IC50: 1 nM
S6897 Epertinib hydrochloride Epertinib hydrochloride (S-222611 hydrochloride) is a potent, orally active, reversible, and selective tyrosine kinase inhibitor of EGFR, HER2 and HER4 with IC50 of 1.48 nM, 7.15 nM and 2.49 nM, respectively. Epertinib hydrochloride (S-222611 hydrochloride) exhibits antitumor activity. Pan HER4, IC50: 2.49 nM
S8814 TAS6417 TAS6417 (CLN-081, TPC-064) is a novel EGFR inhibitor that targets EGFR exon 20 insertion mutations while sparing wild-type (WT) EGFR. IC50 values ranges from 1.1 ± 0.1 to 8.0 ± 1.1 nmol/L. Pan HER4, IC50: 4 nM
S7298 AZ5104 AZ5104, the demethylated metabolite of AZD-9291, is a potent EGFR inhibitor with IC50 of <1 nM, 6 nM, 1 nM, and 25 nM for EGFR (L858R/T790M), EGFR (L858R), EGFR (L861Q), and EGFR (wildtype), respectively. Phase 1. Pan ErbB4, IC50: 7 nM
S7358 Poziotinib (HM781-36B) Poziotinib (HM781-36B, NOV120101) is an irreversible pan-HER inhibitor with IC50 of 3.2 nM, 5.3 nM and 23.5 nM for HER1, HER2, and HER4, respectively. Poziotinib also induces apoptosis and G1 cell cycle arrest. Phase 2. Pan HER4, IC50: 23.5 nM
S2727 Dacomitinib (PF-00299804) Dacomitinib (PF299804, PF299) is a potent, irreversible pan-ErbB inhibitor, mostly to EGFR with IC50 of 6 nM in a cell-free assay. Dacomitinib inhibits ERBB2 and ERBB4 with IC50 of 45.7 nM and 73.7 nM, respectively. Dacomitinib is effective against NSCLCs with EGFR or ERBB2 mutations (resistant to gefitinib) as well as those harboring the EGFR T790M mutation. Dacomitinib inhibits cell growth and induces apoptosis. Phase 2. Pan ErbB4, IC50: 73.7 nM
