包装规格：5mg 10mg 50mg 100mg in glass bottle
产品简介：Osimertinib mesylate (AZD-9291 mesylate) 是不可逆的突变体选择性 EGFR 抑制剂；对EGFRL858R 和EGFRL858R/T790M 的 IC50 值分别为12 和 1 nM。
溶解性：DMSO:13.89 mg/mL (23.32 mM;ultrasonic and warming and heat to 80°C)
储备液保存：-80°C, 2 years -20°C, 1 year (sealed storage, away from moisture)
体内实验：1、请依序添加每种溶剂： 10% DMSO→40% PEG300→5% Tween-80→45% saline Solubility: ≥ 1.39 mg/mL (2.33 mM); Clear solution 此方案可获得 ≥ 1.39 mg/mL (2.33 mM，饱和度未知) 的澄清溶液。 以 1 mL 工作液为例，取 100 μL 13.9 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中，混合均匀；向上述体系中加入50 μL Tween-80，混合均匀；然后继续加入 450 μL生理盐水定容至 1 mL。 2、请依序添加每种溶剂： 10% DMSO→90% (20% SBE-β-CD in saline) Solubility: ≥ 1.39 mg/mL (2.33 mM); Clear solution 此方案可获得 ≥ 1.39 mg/mL (2.33 mM，饱和度未知) 的澄清溶液。 以 1 mL 工作液为例，取 100 μL 13.9 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液中，混合均匀。 3、请依序添加每种溶剂： 10% DMSO→90% corn oil Solubility: ≥ 1.39 mg/mL (2.33 mM); Clear solution 此方案可获得 ≥ 1.39 mg/mL (2.33 mM，饱和度未知) 的澄清溶液，此方案不适用于实验周期在半个月以上的实验。 以 1 mL 工作液为例，取 100 μL 13.9 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中，混合均匀。 ＜1mg/ml表示微溶或不溶。 普西唐提供的所有化合物浓度为内部测试所得，实际溶液度可能与公布值有所偏差，属于正常的批间细微差异现象。 请根据产品在不同溶剂中的溶解度选择合适的溶剂配制储备液；一旦配成溶液，请分装保存，避免反复冻融造成的产品失效。
靶点：EGFRL858R/T790M：1 nM (IC50) EGFRL858R：12 nM (IC50)
体外研究：Osimertinib (AZD-9291) shows similar potency to early generation tyrosine kinase inhibitor (TKIs) in inhibiting EGFR phosphorylation in EGFR cells harboring sensitising EGFR mutants including PC-9 (ex19del), H3255 (L858R) and H1650 (ex19del), with mean IC50 values ranging from 13 to 54 nM for Osimertinib. Osimertinib (AZD-9291) also potently inhibits phosphorylation of EGFR in T790M mutant cell lines (H1975 (L858R/T790M), PC-9VanR (ex19del/T790M), with mean IC50 potency less than 15 nM.
体内研究：The tumor-bearing mice are treated with Osimertinib (AZD-9291) (5 mg/kg/day) for one to two weeks. Within days of treatment, 5 of 5 C/L858R mice displays nearly 80% reduction in tumor volume by magnetic resonance imaging MRI after therapy with Osimertinib, while 5 of 5 mice treated with vehicle shows tumor growth. Osimertinib (AZD-9291) demonstrates improved rat PK, reduced hERG affinity, and improved IGF1R margins relative to the previously described compounds, and so this compound is selected for further investigation. Osimertinib (AZD-9291) also offers an additional degree of broader chemical and profile diversity when compared to the previously described lead compounds. Upon dosing Osimertinib (AZD-9291) in three efficacy models, The comparable efficacy is observed at relatively low doses (10 mg/kg per day). The excellent efficacy is also observed when Osimertinib (AZD-9291) is dosed at 5 mg/kg per day.
