产品描述 | Gefitinib hydrochloride (ZD1839 hydrochloride) is a potent and orally active EGFR tyrosine kinase inhibitor (EGFR-TKI) (IC 50 = 33 nM) that selectively inhibits EGF-stimulated tumor cell growth (IC 50 = 54 nM) and that blocks EGF-stimulated EGFR autophosphorylation in tumor cells. Gefitinib hydrochloride also induces autophagy, which has antitumour activity [1] [2]. |
体外活性 | Gefitinib (0.01-0.1 mM) causes increased phosphotyrosine load of the receptor, increased ERK signalling, and stimulation of proliferation and anchorage-independent growth, presumably by inducing EGFRvIII dimerisation in long-term exposure of EGFRvIII-expressing cells. On the other hand, gefitinib (1-2 mM) significantly decreases EGFRvIII phosphotyrosine load, EGFRvIII-mediated proliferation and anchorage-independent growth [1]. Gefitinib (ZD1839) inhibits the monolayer growth of these EGF-driven untransformed cells with IC 50 of 20 nM [2]. Gefitinib leads to an inhibition of CALU-3 and GLC82 cell proliferation, with an IC 50 of 2 μM [3]. |
体内活性 | Gefitinib (150 mg/kg, p.o.) in conbination with Metformin significant reduces in tumor growth in nude mice bearing H1299 or CALU-3 GEF-R cells that are grown subcutaneously as tumor xenografts [3]. In irradiated rats, Gefitinib treatment augmentes lung inflammation, including inflammatory cell infiltration and pro-inflammatory cytokine expression, while Gefitinib treatment reduces fibrotic lung remodeling due to the inhibition of lung fibroblast proliferation [4]. |

对于不同动物的给药剂量换算,您也可以参考 更多...
请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
