包装规格:5mg 25mg 50mg 100mg in galss bottle
产品简介:一种PI3K-γ的有效抑制剂,选择性是对其他脂质和蛋白激酶的100倍以上。IC50为16nM。
溶解性:溶于DMSO(100mg/mL)
储备液保存:-80°C, 1 years -20°C, 6 months
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 (4.73 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。 2、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 2.5 mg/mL (4.73 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,此方案实验周期在半个月以上的动物实验酌情使用。 以 1 mL 工作液为例,取 100 μL 25.0 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:PI3Kγ:16 nM (IC50);PI3Kα:3.2 μM (IC50);PI3Kβ:3.5 μM (IC50)
体外研究:Eganelisib (IPI549) inhibits PI3Kγ with IC50 of 16 nM, with >100-fold selectivity over other lipid and protein kinases (PI3Kα IC50=3.2 μM, PI3Kβ IC50=3.5 μM, PI3Kδ IC50>8.4 μM). Eganelisib is evaluated for activity across all Class I PI3K isoforms. The binding affinity of Eganelisib for PI3K-γ is determined by measuring the individual rates constants and for PI3K-α, β and δ using equilibrium fluorescent titration. Eganelisib is a remarkably tight binder to PI3Kγ with a Kd of 290 pM and >58-fold weaker affinity for other Class I PI3K isoforms (PI3Kα Kd=17 nM, PI3Kβ Kd=82 nM, PI3Kδ Kd=23 M). In PI3K-α, -β, -γ, and -δ dependent cellular phospho-AKT assays, Eganelisib demonstrates excellent PI3K-γ potency (IC50=1.2 nM) and selectivity against other Class I PI3K isoforms (>146-fold). Cellular IC50s for Class I PI3Kα (250 nM), PI3Kβ (240 nM), PI3Kγ (1.2 nM), PI3Kδ (180 nM) are determined in SKOV-3, 786-O, RAW 264.7, and RAJI cells, respectively, by monitoring inhibition of pAKT S473 by ELISA. Furthermore, Eganelisib dose dependently inhibits PI3Kγ dependent bone marrow-derived macrophage (BMDM) migration. Eganelisib is selective against a panel of 80 GPCRs, ion channels, and transporters at 10 μM.
体内研究:Eganelisib (IPI549) demonstrates favorable pharmacokinetic properties and robust inhibition of PI3K-γ mediated neutrophil migration. In vivo (mice, rats, dog, and monkeys), Eganelisib has excellent oral bioavailability, low clearance, and distributed into tissues with a mean volume of distribution of 1.2 L/kg. Overall, Eganelisib has a favorable pharmacokinetic profile to allow potent and selective inhibition of PI3K-γ in vivo. The t1/2 of IPI-549 for mouse, rat, dog and monkey is 3.2, 4.4, 6.7 and 4.3 h, respectively. Eganelisib significantly reduces neutrophil migration in a dose dependent manner in this model when administered orally at all of the tested doses.
细胞实验:细胞系: SKOV-3细胞 浓度:-- 处理时间:30 min 方法:将SKOV-3以200,000 cells/200 μL/well的密度接种于96孔细胞培养板中,培养于含10% FBS的RPMI-1640培养基中。在5% CO2、37℃培养箱中培养过夜。第二天,加入化合物,DMSO的终浓度为0.5%,在小分子化合物中孵育30分钟(5% CO2,37℃)。然后加入预冷的Lysis buffer,将培养板置于冰上孵育5分钟,3000 rpm,4℃离心5分钟。
