Product Introduction

Bioactivity

名稱	(S)-Afatinib
描述	(S)-Afatinib (BIBW2992) is an irreversible EGFR family inhibitor with IC50s of 0.5/0.4/10/14/1 nM for EGFRwt, EGFR (L858R), EGFR (L858R/T790M), HER2, and HER4, respectively.
細胞實驗	Cells (1×10^4) were transferred into each well of a 96-well plate and cultured over night in serum-free media for EGFR phosphorylation assay. After addition of test compounds on the next day, the plates were then incubated at 37°C for 1 hour. EGF-stimulation was done at 100 ng/ml for 10 min at room temperature. Cells were washed with ice cold PBS before extraction with 120 μl per well HEPEX buffer and shaken for 1 h at room temperature. In all 2×10^4 cells per well was used for HER2 phosphorylation assay. Streptavidin precoated plates were coated with anti-EGFR-biotin at 1:100 dilution with blocking buffer and c-erb2/HER2 oncoprotein Ab-5(Clone N24)-Biotin. Extracts from above steps were then transferred to the antibody-coated wells and incubated for 1 h at room temperature. Assessment of color development is described in Supplementary information. Extinction was measured at 450 nm. The data generated were analysed by the program PRISM. Normalized values were used to calculate the IC50 by a nonlinear regression curve fit (variable slope) [1].
激酶實驗	The wild type tyrosine kinase domain of the human EGFR, as well as the EGFR L858R/T790M double mutant, were fused to Glutathione-S-transferase (GST) and extracted as described in Supplementary methods. The L858R mutant was purchased from Upstate. Enzyme activity was then assayed in the presence or absence of serial inhibitor dilutions performed in 50% Me2SO. A random polymer pEY (4:1) from Sigma was used as substrate. Biotinylated pEY was added as a tracer substrate. The kinase domain of HER2 was cloned using baculovirus system and extracted similarly to that of EGFR kinase domain. Detailed procedures for EGFR, HER2, SRC, BIRK and VEGFR2 kinase activity assays are included in Supplementary information [1].
動物實驗	Six weeks old female athymic nude mice (nu/nu) weighing about 16-20 gram were housed by Laboratory Animal Services Centre of The Chinese University of Hong Kong. The experiment was conducted by researchers under license from the Hong Kong Government Department of Health and according to approval given by Animal Experimentation Ethics Committee of the Chinese University of Hong Kong. ESCC xenografts were established by inoculating HKESC-2 (0.6 × 10^5 cells re-suspended in 50 μl of HBSS-buffer) subcutaneously into both flanks of the nude mice. When tumor size reached to 4-6 mm diameter, they were randomized in either treatment (15 mg/kg) or vehicle control group. Afatinib for treatment was prepared by dissolving in 0.5% methylcellulose before administration. Either drug or vehicle was administered to mouse by oral gavage in a schedule of 5 days on plus 2 days off for two weeks. Drug efficacy was evaluated by monitoring the change in tumor size with caliper. Tumor volume was calculated with the formula Tumor Volume = (width2 × length)/2 [2].
體外活性	(S)-Afatinib對EGFR與HER2的野生型及其突變形式展示出強大活性（IC50分別為：EGFRwt 0.5 nM、EGFR L858R 0.4 nM、EGFR L858R/T790M 10 nM、HER2 14 nM）。在人類乳腺癌細胞系中，使用100 nM (S)-Afatinib足以阻止hereregulin刺激的HER3磷酸化作用[1]。食管鱗狀細胞癌（ESCC）細胞系對于afatinib敏感，IC50濃度處于較低μM范圍內（72小時培養(yǎng)下：HKESC-1 = 0.002 μM、HKESC-2 = 0.002 μM、KYSE510 = 1.090 μM、SLMT-1 = 1.161 μM與EC-1 = 0.109 μM）。ErbB家族下游效應物如pAKT、pS6與pMAPK的磷酸化在HKESC-2與EC-1中被顯著抑制。兩個細胞系在暴露于afatinib后24小時觀察到凋亡現象[2]。
體內活性	每日口服BIBW2992，劑量為20 mg/kg，連續(xù)25天治療，顯著促進腫瘤退化并下調EGFR和AKT的磷酸化水平。通過NCIH1975細胞系（表達EGFR L858R/T790M）引起的異種移植瘤形成，經BIBW2992處理后被有效控制，20 mg/kg劑量的T/C值為12% [1]。Afatinib能有效抑制小鼠體內HKESC-2腫瘤生長，且無明顯毒副作用；單獨使用Afatinib在體內模型中對食管鱗狀細胞癌（ESCC）表現出優(yōu)秀的生長抑制效果 [2]。
存儲條件	Powder: -20°C for 3 years \| In solvent: -80°C for 1 year \| Shipping with blue ice.
溶解度	H2O : < 1 mg/mL (insoluble or slightly soluble) DMSO : 90 mg/mL (185.2 mM) Ethanol : 12 mg/mL (24.7 mM) 10% DMSO+40% PEG300+5% Tween 80+45% Saline : 9 mg/mL (18.52 mM), Suspension. Please add co-solvents sequentially, clarifying the solution as much as possible before adding the next one. Dissolve by heating and/or sonication if necessary. Working solution is recommended to be prepared and used immediately.
