产品描述 Pelitinib (EKB-569) (EKB-569) is an effective irreversible EGFR inhibitor (IC50: 38.5 nM).
靶点活性 EGFR:38.5 nM
体外活性 在达EGFR的A431异种移植模型中,Pelitinib(10 mg/kg,p.o.)可有效抑制EGFR磷酸化,1 h内抑制90%,24 h后抑制率>50%.小鼠气道上皮细胞重构模型,可被病毒感染诱导,具有延迟但永久性转变为杯状细胞化生的特点,Pelitinib(20 mg/kg/day)可完全阻断纤毛细胞的增加和Clara细胞的减少,从而从3个方面校正上皮细胞重构,并明显抑制杯状细胞的发生.Pelitinib(20 mg/kg/day)抑制APCMin/+小鼠体内87%的肿瘤发生,与2倍剂量EKI-785(40 mg/kg/day)的作用接近,与体内活性较高一致. Pelitinib对体内气道上皮细胞中EGFR信号有选择性抑制效果.
体内活性 Pelitinib(75-500 nM)可特异性抑制AKT和ERK1/2的活化,而对NF-κB通路无影响。在正常人角质细胞中,Pelitinib也可有效抑制TGF-α介导的EGFR活化(IC50:56 nM),抑制STAT3和ERK1/2的活化(IC50:60 nM和62 nM)。在A431和正常人角质细胞中,Pelitinib对EGF诱导的EGFR磷酸化有抑制作用(IC50:20-80 nM),还抑制STAT3的磷酸化(IC50:30-70 nM)。 Pelitinib对正常人角质细胞(IC50:61 nM),以及A431(IC50:125 nM)和MDA-468(IC50:260 nM)肿瘤细胞的增殖有明显抑制作用,但对MCF-7细胞活性较低(IC50:3.6 μM)。
激酶实验 Autophosphorylation of EGFR in cells: For experiments using cells in culture, A431 cells are treated with various concentrations of Pelitinib for 2.75 hours before co-incubation with 100 ng/mL EGF for 0.25 hour. Cells are washed twice with cold phosphate-buffered saline (PBS) before adding to lysis buffer (10 mM Tris, pH 7.5, 5 mM ethylenediamine tetra-acetic acid (EDTA), 150 mM NaCl, 1% Triton X-100, 1% Sodium deoxycholate, 0.1 % SDS, 1 mM PMSF, 10 mg/mL pepstatin A, 10 mg/mL leupeptin, 20 KIU/mL aprotinin, 2 mM sodium orthovanadate, and 100 mM sodium fluoride) for 20 minutes on ice, before immunoprecipitation and SDS-PAGE-immunoblotting. For immunoprecipitation, cultured cells are placed in cold lysis buffer and immediately homogenized on ice with a polytron with several pulses. The homogenate is first centrifuged at 2500 rpm (20 minutes, 4 °C) and then again at 14,000 rpm in a microcentrifuge (10 minutes, 4 °C). Supernatants (1000 μg protein) are incubated for 2 hours at 4 °C with 15 mL of EGFR polyclonal antibody. After 2 hours, 50 μL of protein G plus/protein A agarose beads is added and incubated with constant rotation for 2 hours at 4 °C. After washing with lysis buffer, beads are boiled for 2 minutes in Laemmli sample buffer. Proteins are then resolved by SDS-PAGE, transferred to immobilon membrane and probed overnight with an anti-phosphotyrosine antibody conjugated with horseradish peroxidase (HRP). Membranes are developed using the ECL reagent. Total EGFR protein is determined by stripping membranes and re-probing with receptor-specific antibodies. Quantitation of bands is done by densitometry, using ImageQuant software with a Molecular Dynamics laser transmittance scanner.
细胞实验 Cells are seeded in 96-well dishes, and after 2 hours, Pelitinib is added and incubated for 5 days. After incubation, the medium is removed from each well and fresh medium (150 μL) + 1 mg/mL MTT solution (50 μL) is added. After incubation for 2 hours at 37 °C, the medium is replaced with 150 μL DMSO, and absorbance at 540 nm in each well is determined. The IC50 is calculated by linear regression of the data.
