生物活性:
BI-4142 is a potent, highly selective and orally active HER2 inhibitor with an IC50 of 5 nM.

体内研究:
BI-4142 (0-100 mg/kg; p.o.; twice per day for 40 days) inhibits tumor growth and inhibits oncogenic signaling.Animal Model:NMRI-Foxn1nu mice, PC-9 HER2YVMA xenograft model
Dosage:3, 10, 30 and 100 mg/kg
Administration:Oral administration, twice per day for 40 days
Result:Resulted in tumor regressions in a dose-dependent manner (113%, 126%, 153% and 166% tumor growth inhibition at 3, 10, 30 and 100 mg/kg, respectively).
Animal Model:BomTac:NMRI Foxn1nu mice
Dosage:1 mg/kg or 10mg/kg and 100 mg/kg
Administration:IV for 1 mg/kg, PO for 10mg/kg and 100 mg/kg (Pharmacokinetic Analysis)

体外研究:
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.BI-4142 (1 nM-5 μM, 72?h or 96?h) shows antiproliferative activity against tumor cells.BI-4142 displays good permeability and no PgP-mediated efflux liability in the CaCo-2 assay.BI-4142 inhibits HER2-dependent cell lines and inhibits downstream signaling.
