| 包装规格: | 2mg 5mg 10mg 25mg 50mg 100mg in glass bottle |
| 产品简介: | 一种EGFR抑制剂,抑制EGFR,EGFRL858R,EGFRT790M,EGFRL858R/T790M和ErbB2的IC50值分别为0.75,0.5,0.79,2.3,19nM。 |
| 溶解性: | 溶于DMSO(≥28mg/m) |
| 储备液保存: | -80°C, 6 months -20°C, 1 month (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: ≥ 2.08 mg/mL (2.44 mM); 澄清溶液 此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 20.8 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 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: ≥ 2.08 mg/mL (2.44 mM); 澄清溶液 此方案可获得 ≥ 2.08 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 20.8 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。 <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: | EGFR:0.75nM(IC50);EGFRL858R:0.5 nM(IC50);EGFRT790M:0.79 nM(IC50);EGFRL858R/T790:2.3 nM (IC50);ErbB2:19 nM (IC50) |
| 体外研究: | AV-412 inhibits autophosphorylation of EGFR and ErbB2 with IC50 of 43 and 282 nM, respectively. AV-412 also inhibits epidermal growth factor (EGF)-dependent cell proliferation with an IC50 of 100 nM. AV-412 abrogates EGFR signaling in the gefitinib-resistant H1975 cell line, which harbors a double mutation of L858R and T790M in EGFR. |
| 体内研究: | In animal studies using cancer xenograft models, AV-412 (30 mg/kg) demonstrates complete inhibition of tumor growth of the A431 and BT-474 cell lines, which overexpress EGFR and ErbB2, respectively. AV-412 suppresses autophosphorylation of EGFR and ErbB2 at the dose corresponding to its antitumor efficacy. When various dosing schedules are applied, AV-412 shows significant effects with daily and every-other-day schedules, but not with a once-weekly schedule, suggesting that frequent dosing is preferable for this compound. Furthermore, AV-412 shows a significant antitumor effect on the ErbB2-overexpressing breast cancer KPL-4 cell line, which is resistant to gefitinib. |
