| Targets |
EGFR-IN-1 HCl targets the epidermal growth factor receptor (EGFR), specifically the L858R/T790M mutant form. It is an irreversible inhibitor that covalently binds to the kinase domain of the mutant EGFR. Its 100-fold selectivity for the mutant over wild-type EGFR reduces potential toxicity in normal tissues.

| ln Vitro |
EGFR-IN-1 hydrochloride (compound 24) had a substantial antiproliferative effect on H1975 and HCC827 cells, with IC50 values of 4 and 28 nM, respectively, after being applied for 72 hours (10 μM) [1]. In H1975 and HCC827 cells, EGFR-IN-1 hydrochloride suppresses p-EGFR with IC50 values of 4 and 9 nM, respectively. A panel of 100 kinases is highly selective for EGFR-IN-1 [1].
In vitro, EGFR-IN-1 HCl is a potent inhibitor of the L858R/T790M mutant EGFR with 100-fold selectivity over wild-type EGFR. It shows potent anti-tumor and anti-proliferative activity in H1975 cells (which harbor the L858R/T790M mutation) and mutant HCC827 cells with IC50s of 4 and 28 nM, respectively. Its irreversible binding ensures sustained inhibition. |
| ln Vivo |
EGFR-IN-1 hydrochloride (30 mg/kg; oral; once daily for 2 weeks) revealed considerable tumor growth inhibition without noticeable weight loss [1]. EGFR-IN-1 hydrochloride was assessed in a time-course PD experiment at an oral dose of 30 mg/kg. EGFR-IN-1 reduces EGFR phosphorylation by >50%, lasting >12 hours. EGFR-IN-1 achieved a maximum concentration of 0.10 μM at 2 hours, with a systemic exposure (AUC0-inf.) of 0.33 μM. h[1].
In vivo, EGFR-IN-1 HCl (30 mg/kg; p.o.; daily for 2 weeks) displays significant tumor growth inhibition with no observed loss in body weight. It is evaluated in a time course pharmacodynamic experiment upon oral dosing at 30 mg/kg. The compound's oral bioavailability and efficacy make it a promising candidate for treating gefitinib-resistant NSCLC. |
| Enzyme Assay |
The in vitro enzyme inhibition assay for EGFR-IN-1 HCl measures its ability to inhibit EGFR kinase activity. The assay is performed using purified EGFR enzymes (wild-type and L858R/T790M mutant) and a peptide substrate. The compound's ability to inhibit substrate phosphorylation is measured, and IC50 values are calculated. The 100-fold selectivity for the mutant over wild-type is confirmed in these assays.

In vivo animal experiments are performed using xenograft models of gefitinib-resistant NSCLC. Tumor-bearing mice are administered EGFR-IN-1 HCl via oral gavage at 30 mg/kg daily for 2 weeks. Tumor volume is measured over time. Pharmacodynamic studies evaluate EGFR phosphorylation and downstream signaling in tumor tissues. Body weight is monitored to assess tolerability. |
| ADME/Pharmacokinetics |
EGFR-IN-1 HCl has a molecular formula and molecular weight consistent with its structure. It is soluble in DMSO and other organic solvents. For storage, it should be kept at -20°C, protected from light and moisture. The compound is supplied with high purity for research purposes. For in vivo administration, appropriate formulations should be used. It is an orally active compound.

| Toxicity/Toxicokinetics |
As a potent and irreversible EGFR inhibitor, EGFR-IN-1 HCl is not intended for human use as a research chemical. Its toxicological profile is not fully characterized. Standard laboratory safety precautions should be followed when handling it. Its effects are related to its mechanism as an EGFR mutant-selective inhibitor, which could have significant biological consequences.
