Description

EGFR-IN-44 (Compound 6a) is a potent, orally active EGFR tyrosine kinase inhibitor with an IC50 of 4.11 nM. EGFR-IN-44 induces cell apoptosis and shows an oral bioavailability value of 33.57%. EGFR-IN-44 can be studied for non-small-cell lung cancers[1].

IC50 & Target

IC50: 0.26 nM (EGFR T790M/L858R), 1.33 nM (EGFR L858R), 4.11 nM (EGFR)[1]

In Vitro

EGFR-IN-44 (Compound 6a) (0-10 µM, 72 h) shows anti-proliferative activities against tumor cell lines[1].
EGFR-IN-44 binds to the ATP binding site of EGFR[1].
EGFR-IN-44 (0-10 nM, 48 h) induces H1975 cell apoptosis via the mitochondrial pathway, arrests cell cycle in G0/G1 phase, and suppresses cell migration[1].
EGFR-IN-44 (0-10 nM, 48 and 72h) shows hypotoxicity against normal cells[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Cell Proliferation Assay[1]

Cell Line: H1975 (EGFRT790M/L858R), PC9 (EGFRdel19), and H292 (EGFRWT)
Concentration: 0-10 µM
Incubation Time: 72 h
Result: Showed anti-proliferative activities with IC50 values of 0.0022 ± 0.001, 0.0048 ± 0.001, and 4.499 ± 0.057 µM against H1975, PC9, and H292 cells, respectively.

Apoptosis Analysis[1]

Cell Line: H1975
Concentration: 1, 5, and 10 nM
Incubation Time: 48 h
Result: Effectively induced cell apoptosis in a dose-dependent manner. Resulted in 33.7%, 52.4%, and 56.2% apoptosis at 1, 5, and 10 µM, respectively, compared to 5.81% apoptosis in the control group.

Western Blot Analysis[1]

Cell Line: H1975
Concentration: 5, 10, and 25 nM
Incubation Time: 48 h and 72 h
Result: Dose-dependently upregulated the expression levels of the proapoptotic proteins Bad and Bax and downregulated the expression level of the antiapoptotic protein Bcl-2. Sufficiently reduced the phosphorylation of EGFR and AKT.

Cell Cycle Analysis[1]

Cell Line: H1975
Concentration: 5 nM
Incubation Time: 0, 12, 24, or 48 h
Result: Exhibited a significant increase in the G0/G1 cell population and a dramatic decrease in G2/M phase.

Cell Cytotoxicity Assay[1]

Cell Line: LO2, HK2, HLF, and 293A
Concentration: 0.1, 1, 5, and 10 µM
Incubation Time: 48 h and 72 h
Result: Showed hypotoxicity with IC50 values of 7.247, 4.586, 3.787, and 2.925 µM against LO2, HK2, HLF, and 293A cells, respectively. The cell morphology was changed compared to the control.
In Vivo

EGFR-IN-44 (Compound 6a) (25 mg/kg; i.g.; daily, 7days) shows strong antitumor activity without obvious toxicity[1].

MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.

Animal Model: Male BALB/c nude mice (5 weeks old, 18 - 20 g), H1975 xenograft model[1]
Dosage: 25 mg/kg
Administration: Intragastric administration, daily, 7 days
Result: Showed strong tumor inhibition (TGI = 90.24%) without obvious toxicity.
Animal Model: Male Sprague–Dawley (SD) rats[1]
Dosage: 1 mg/kg and 5 mg/kg
Administration: Intravenous injection and oral administration (Pharmacokinetic Analysis)
Result: In Vivo PK parameters of EGFR-IN-44 [1]

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
