BI-4142 is a potent, highly selective and orally active HER2 inhibitor with an IC50 of 5 nM[1].
BI-4142 shows inhibition with IC50 values of 10 nM, 18 nM, 270 nM and 2400 nM against HEK HER2YVMA, Ba/F3 HER2YVMA, HEK EGFRWT and Ba/F3 EGFRWT, respectively[1].
BI-4142 (1 nM-5 μM, 72 h or 96 h) shows antiproliferative activity against tumor cells[1].
BI-4142 displays good permeability and no PgP-mediated efflux liability in the CaCo-2 assay[1].
BI-4142 inhibits HER2-dependent cell lines and inhibits downstream signaling[1].

| Cell Line: | NCI-H2170 HER2WT, NCI-H2170 HER2YVMA, A431 EGFRWT, Ba/F3 HER2YVMA, Ba/F3 HER2YVMA,S783C, Ba/F3 EGFRWT and Ba/F3 EGFRC775S cells |
| Concentration: | 1 nM-5 μM |
| Incubation Time: | 72 h or 96 h |
| Result: | Showed antiproliferative effect with IC50 values of 16 nM, 82 nM, >5 µM, 4 nM, 24 nM, 718 nM and 43 nM against NCI-H2170 HER2WT, NCI-H2170 HER2YVMA, A431 EGFRWT, Ba/F3 HER2YVMA, Ba/F3 HER2YVMA,S783C, Ba/F3 EGFRWT and Ba/F3 EGFRC775S, respectively. |
BI-4142 (0-100 mg/kg; p.o.; twice per day for 40 days) inhibits tumor growth and inhibits oncogenic signaling[1].
