    Differential sensitivity of EGFR-mutant glioma and lung cancer cell lines to the irreversible EGFR inhibitors HKI-272 and CI-1033. C, HKI-272 is more potent than CI-1033 in blocking EGFR phosphorylation in SKMG3 cells with EGFR EC mutation. SKMG3 cells were treated with the indicated doses of CI-1033 or HKI-272, and whole lysates were analyzed by immunoblot with the indicated antibodies.

    Differential sensitivity of EGFR-mutant glioma and lung cancer cell lines to the irreversible EGFR inhibitors HKI-272 and CI-1033. A, HKI-272 induces cell death in GBM cells with EGFR EC mutation (SKMG3, SF268) but not EGFR wild-type (WT EGFR) cancer cell lines or astrocytes (NHA). Cell death was assessed by trypan blue exclusion after 5 days of inhibitor treatment. Cells lines in black express wild-type EGFR, whereas those in red contain EGFR EC mutations.

  • HER2 mutations V777L, D769H, V842I, G309A induce gain-of-function over HER2 WT in MCF10A mammary epithelial cells. B, HER2 WT, L755S, and del.755–759 cells were grown in Matrigel in the presence of DMSO vehicle (0.5%), neratinib (0.5  μmol/L) or gefitinib (0.5  μmol/L). Phase contrast images were obtained as in A. C,  MCF10A-HER2 WT or mutants were seeded in soft agar. After 7 days of growth, they were treated with DMSO vehicle (0.5%), lapatinib (0.5 μmol/L) or neratinib (0.5 μmol/L) for an additional week. Error bars represent 95% highest posterior density intervals. *, Significant difference between the HER2 mutant and HER2 WT; #, the effect of inhibitor treatment was significant (95% highest posterior density interval did not contain 0 for both).  D, photomicrographs of the colonies in soft agar on day 12, magnification ×40.

製品説明 Neratinib (HKI-272) is a highly selective HER2 and EGFR inhibitor with IC50 of 59 nM and 92 nM in cell-free assays; weakly inhibits KDR and Src, no significant inhibition to Akt, CDK1/2/4, IKK-2, MK-2, PDK1, c-Raf and c-Met. Phase 3.

Neratinib weakly inhibits tyrosine kinases KDR and Src with IC50 of 0.8 μM and 1.4 μM, respectively, being 14- and 24-fold less active compared with HER2. Neratinib displays no activity against other serine-threonine kinases such as Akt, cyclin D1/cdk4, cyclin E/cdk2, cyclin B1/cdk1, IKK-2, MK-2, PDK1, c-Raf, and Tpl-2, as well as the tyrosine kinase c-Met. Neratinib selectively inhibits the proliferation of 3T3 cells transfected with the HER2 (3T3/neu), as well as two other HER-2-overexpressing SK-Br-3 and BT474 cells with IC50 values of 2-3 nM, displaying >230-fold potency compared with non-transfected 3T3 cells as well as MDA-MB-435 and SW620 which are EGFR- and HER2-negative. Neratinib also inhibits the proliferation of EGFR-dependent A431 cells with an IC50 of 81 nM. Neratinib reduces HER2 receptor autophosphorylation in BT474 cells with an IC50 of 5 nM, and EGF-dependent phosphorylation of EGFR in A431 cells with IC50 of 3 nM. Blocking of HER-2 by Neratinib results in inhibition of downstream MAPK and Akt pathways with IC50 of 2 nM, more potently than Trastuzumab. Neratinib inhibits the cyclin D1 expression and the phosphorylation of the Rb-susceptibility gene production in BT474 cells with IC50 of 9 nM, leading to G1-S arrest and ultimately decreased cell proliferation.

体内試験 Oral administration of Neratinib significantly inhibits the growth of 3T3/neu xenografts, with inhibition of 34%, 53%, 98%, and 98% at dose of 10, 20, 40, and 80 mg/kg/day, respectively. Consistent with the inhibition of HER-2 phosphorylation by 84% within 1 hour of administration at 40 mg/kg/day, Neratinib inhibits the growth of BT474 xenografts by 70-82%, 67%, and 93% at dose of 5, 10, and 40 mg/kg/day, respectively. Neratinib is also effective against SK-OV-3 xenografts with inhibition of 31% and 85% at 5 and 60 mg/kg/day, respectively. Neratinib is less potent against EGFR-dependent A431 xenografts than HER-2-dependent tumors, with 32% and 44% inhibition at 5 and 20 mg/kg/day, respectively. Neratinib displays little activity against MCF-7 and MX-1 xenografts expressing low levels of HER-2 and EGFR, with only 28% inhibition at 80 mg/kg/day, suggesting that Neratinib has selective activity for cells expressing HER-2 or EGFR.

Cell-free autophosphorylation assay using time-resolved fluorometry:

Neratinib is prepared as 10 mg/mL stocks in DMSO and diluted in 25 mM HEPES (pH 7.5; 0.002 ng/mL-20 μg/mL). Purified recombinant COOH-terminal fragments of HER2 (amino acids 676-1255) or epidermal growth factor receptor (EGFR) (amino acids 645-1186) [diluted in 100 mM HEPES (pH 7.5) and 50% glycerol] is incubated with increasing concentrations of Neratinib in 4 mM HEPES (pH 7.5), 0.4 mM MnCl2, 20 μM sodium vanadate, and 0.2 mM DTT for 15 minutes at room temperature in 96-well ELISA plates. The kinase reaction is initiated by the addition of 40 μM ATP and 20 mM MgCl2 and allowed to proceed for 1 hour at room temperature. Plates are washed, and phosphorylation is detected using Europium-labeled anti-phospho-tyrosine antibodies (15 ng/well). After washing and enhancement steps, signal is detected using a Victor2 fluorescence reader (excitation wavelength 340 nm, emission wavelength 615 nm). The concentration of Neratinib that inhibits receptor phosphorylation by 50% (IC50) is calculated from inhibition curves.

  • 実験の流れ: Cells are exposed to various concentrations of Neratinib for 2, or 6 days. Cell proliferation is determined using sulforhodamine B, a protein binding dye. Briefly, cells are fixed with 10% trichloroacetic acid and washed extensively with water. Cells are then stained with 0.1% sulforhodamine B and washed in 5% acetic acid. Protein-associated dye is solubilized in 10 mM Tris, and absorbance is measured at 450 nM. The concentration of Neratinib that inhibits cell proliferation by 50% (IC50) is determined from inhibition curves.
