熔点：溶于DMSO
包装规格：5mg 10mg 25mg 50mg 100mg in glass bottle
产品简介：一种具有选择性的和潜在抗癌活性的Met、TIE2、VEGFR2和Trk激酶抑制剂，IC50 值分别为2.7、8、9.2和0.83nM。
储备液保存：-80°C, 2 years -20°C, 1 year
体内实验：1、请依序添加每种溶剂：10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 2.5 mg/mL (4.90 mM); 澄清溶液 此方案可获得 ≥ 2.5 mg/mL（饱和度未知）的澄清溶液。 以 1 mL 工作液为例，取 100 μL 25.0 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。 ＜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：VEGFR2:9.2nM(IC50);Trk1:0.85nM(IC50);Trk2:4.6nM(IC50);Trk3:0.93nM(IC50);MET:2.7nM(IC50);TIE2:8nM(IC50);FLT3:9.3 nM (IC50)
体外研究：Altiratinib also inhibits MET isoforms METD1228H, METD1228N, METY1230C, METY1230D, METY1230H, METM1250T with IC50s of 3.6, 1.3, 1.2, 0.37, 1.5 and 6 nM, respectively. Altiratinib inhibits MET phosphorylation with IC50 values of 0.85 and 2.2 nM, respectively. In the U-87 glioblastoma cell line, MET and HGF are both expressed. Altiratinib blocks autocrine activation of MET phosphorylation in these cells (IC50=6.2 nM). Altiratinib potently inhibits cellular proliferation in MET-amplified EBC-1 and MKN-45 cells, as well as TPM3-TRKA fusion KM-12 cells. Activation of MET is known to increase the motility and invasiveness of cancer cells: Altiratinib inhibits HGF-induced A549 cell migration, with an IC50 of 13 nM. Altiratinib also inhibits FLT3-ITD mutant MV-4-11 cell proliferation with an IC50 of 12 nM.
体内研究：A single oral dose of 30 mg/kg Altiratinib leads to >95% inhibition of MET phosphorylation for the entire 24-hour period. A single 10 mg/kg oral dose of Altiratinib exhibits complete inhibition of MET phosphorylation through 12 hours and 73% inhibition at 24 hours postdose. Altiratinib dosed at 10 mg/kg twice a day leads to a significant 90% decrease in BLI signal. Altiratinib exhibits properties amenable to oral administration and exhibits substantial blood–brain barrier penetration, an attribute of significance for eventual treatment of brain cancers and brain metastases.
