包装规格：5mg 25mg 100mg in glass bottle
产品简介：一种有效的选择性PI3Kγ抑制剂，IC50为30±10nM。
溶解性：溶于DMSO(25mg/mL超声）
储备液保存：-80°C, 2 years -20°C, 1 year
靶点：PI3Kα:935 nM (IC50);PI3Kγ:30 nM (IC50);PI3Kδ:20 μM (IC50);PI3Kβ:20 μM (IC50)
体外研究：AS-252424 also inhibits PI3Kα, PI3Kβ and PI3Kδ with IC50s of 935±150 nM, 20 μM and 20 μM, respectively. AS-252424 inhibits MCP-1-mediated chemotaxis in wild-type primary monocytes in a concentration-dependent manner with an IC50 value of 52 μM, as well as in the monocytic cell line THP-1 with an IC50 value of 53 μM. In the human monocytic cell line THP-1, MCP-1 binding to the GPCR chemokine receptor CCR2, strongly induces phosphorylation of PKB/Akt, which is effectively inhibited by AS-252424 at IC50 values as low as 0.4 μM. In contrast, induction of PKB/Akt phosphorylation by colony stimulating factor (CSF-1), binding to the growth factor receptor c-fms, is only blocked by AS-252424 at IC50 values as high as 4.7 μM.
体内研究：Oral administration of AS-252424 in a mouse model of acute peritonitis leads to a significant reduction of leukocyte recruitment. To evaluate the efficacy of AS-252424 to block leukocyte migration in vivo, it is tested in a mouse model of thioglycollate-induced peritonitis. Oral administration of AS-252424 at 10 mg/kg results in moderate reduction of neutrophil recruitment (35%±14%), almost matching the result observed in PI3Kγ-deficient mice. Given the short oral half-life of AS-252424 (t1/2=1 h) and relative high clearance (2.25 L/kg per h), investigations at later time points (24-48 h) to assess macrophage and monoycyte recruitment are not undertaken. The modest pharmacokinetic properties do not appear to be caused by rapid oxidative metabolism (microsomal metabolism after 1 h: 16% (rat), 10% (human)).
激酶实验：体外PI3Kγ激酶试验： 人PI3Kγ (100 ng)在室温下与激酶缓冲液(10 mM MgCl2，1 mM β-甘油磷酸盐，1 mM DTT，0.1 mM Na3VO4，0.1% 胆酸钠和15 M ATP/100 nCi γ[33]ATP，终浓度)，包含18 M PtdIns和250 M PtdSer (终浓度)的脂囊泡，以及AS-252424或DMSO进行培养。激酶反应通过加入250 g Neomycin包被的闪烁迫近分析(SPA)珠停止。
细胞实验：细胞系：Raw-264巨噬细胞 浓度：0.01 nM 到 0.1 μM 处理时间：5分钟 方法：在无血清培养基中饥饿培养3小时后，Raw-264巨噬细胞用AS-252424 或 DMSO预处理30分钟，并用50 nM C5a刺激5分钟。PKB/Akt磷酸化使用磷酸-Ser-473 Akt特异性抗体和标准ELISA协议进行监测。
动物实验：动物模型：对雌性 C3H 小鼠腹腔注射巯基乙酸盐(40 ml/kg)以诱导产生腹膜炎小鼠模型 剂量：10 mg/kg
保存条件：-20℃
