| 製品説明 | Neratinibは、無細胞アッセイにおいてIC50が59 nMおよび92 nMである、高選択的なHER2およびEGFR阻害剤です。KDRおよびSrcを弱く阻害し、Akt、CDK1/2/4、IKK-2、MK-2、PDK1、c-Raf、c-Metに対して有意な阻害はありません。フェーズ3。 |

| in vitro | 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. This compound 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. It 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. This chemical also inhibits the proliferation of EGFR-dependent A431 cells with an IC50 of 81 nM. It 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 this compound results in inhibition of downstream MAPK and Akt pathways with IC50 of 2 nM, more potently than Trastuzumab. It 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. |
| in vivo | 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, this compound inhibits the growth of BT474 xenografts by 70-82%, 67%, and 93% at dose of 5, 10, and 40 mg/kg/day, respectively. It is also effective against SK-OV-3 xenografts with inhibition of 31% and 85% at 5 and 60 mg/kg/day, respectively. This chemical 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. It 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 it has selective activity for cells expressing HER-2 or EGFR. |

| 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 this compound 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 this chemical 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 this compound that inhibits cell proliferation by 50% (IC50) is determined from inhibition curves. | |
