| Targets |
BI-4142 targets HER2 (human epidermal growth factor receptor 2), a receptor tyrosine kinase involved in cell proliferation and survival. HER2 is overexpressed or mutated in various cancers, including breast cancer and non-small cell lung cancer. By inhibiting HER2, BI-4142 blocks downstream signaling pathways that drive tumor growth. The compound is selective for HER2 and targets exon 20 insertion mutants.

| ln Vitro |
BI-4142 has IC50 values of 10 nM, 18 nM, 270 nM, and 2400 nM, respectively, indicating that it inhibits HEK HER2YVMA, Ba/F3 HER2YVMA, HEK EGFRWT, and Ba/F3 EGFRWT [1]. The anti-proliferative activity of BI-4142 (1 nM-5 μM, 72 hours or 96 hours) against tumor cells has been reported [1]. In the CaCo-2 experiment, BI-4142 shows high permeability and no propensity for PgP-mediated efflux [1]. BI-4142 suppresses downstream signaling and HER2-dependent cell lines [1].
In vitro, BI-4142 shows inhibition with IC50 values of 10 nM, 18 nM, 270 nM, and 2400 nM against HEK HER2YMM cells. It is a potent inhibitor of HER2 with an IC50 of 5 nM. The compound inhibits HER2-dependent cell proliferation and downstream signaling. |
| ln Vivo |
BI-4142 (0-100 mg/kg; oral; twice daily for 40 days) suppresses oncogenic signaling and tumor development [1]. Tumor growth inhibition was 113%, 126%, 153%, and 166% at 3, 10, 30, and 100 mg/kg, respectively. Animal Models: NMRI-Foxn1nu mice, PC-9 HER2YVMA xenograft model [1]. Dosage: 3, 10, 30, and 100 mg/kg. Administration: Oral twice daily for 40 days. Results: At dose -caused tumor regression in a dependent manner.
In vivo, BI-4142 has been studied in preclinical models. Oral administration twice daily for 40 consecutive days showed efficacy. The compound has shown potential in preclinical studies for reducing inflammation and improving cellular function in Parkinson's disease models. It is under investigation for its safety and efficacy in clinical trials. |
| Enzyme Assay |
A cell-free assay for BI-4142 would involve measuring its inhibition of HER2 kinase activity. In these assays, recombinant HER2 kinase is incubated with a peptide substrate and ATP in the presence of varying concentrations of the compound. The incorporation of phosphate into the substrate is measured, and IC50 values are calculated. For BI-4142, the IC50 for HER2 is 5 nM.

Cellular assays for BI-4142 typically involve assessing its effects on HER2-dependent cell proliferation and signaling. Cells expressing HER2 (e.g., HEK HER2YMM cells) are treated with the compound, and cell viability is measured. The inhibition of downstream signaling, such as phosphorylation of HER2 and its substrates, can be assessed by Western blotting. |
