产品描述:基本信息 产品编号: P11138 产品名称: Parecoxib Sodium CAS: 198470-85-8   储存条件 粉末 2-8℃ 四年     分子式: C19H17N2NaO4S 溶于液体 -80℃ 6个月 分子量: 392.40 -20℃ 1个月 化学名:  N-[4-(5-METHYL-3-PHENYLISOXAZOL-4-YL)PHENYLSULFONYL]PROPIONAMIDE, SODIUM SALT Solubility (25°C):   体外:   DMSO 78mg/mL (198.77mM) Ethanol   Water 12.5mg/mL (31.85mM) 体内(现配现用):   <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。   制备储备液   浓度   溶液体积 质量   1mg   5mg   10mg 1mM 2.5484mL 12.7421mL 25.4842mL 5mM 0.5097mL 2.5484mL 5.0968mL 10mM 0.2548mL 1.2742mL 2.5484mL 50mM 0.0510mL 0.2548mL 0.5097mL   生物活性 产品描述 一种选择性强、口服活性强COX-2抑制剂。 靶点 COX-2   体外研究 Parecoxib Sodium (0-200μM;24-48 hours) inhibits the cell proliferation of GBM cells in a dose-dependent manner in GBM cells.Parecoxib Sodium (200μM;24-48 hours) results in a decreased migratory ability of U343 cells than PBS-treated group. Cell Viability Assay Cell Line: GBM cells:U251 and U343 cells Concentration: 0μM,20μM,50μM,100μM and 200μM Incubation Time: 24-48 hours Result: Resulted in a slower BrdU incorporation rate of GBM cells including U251 and U343 cells. 体内研究 Parecoxib Sodium (intraperitoneal injection;2.5,5.0 or 10mg/kg;once a day;21 days) does not affect locomotor activity in the elevated plus-maze test,and Parecoxib at 5 and 10mg/kg shows higher levels of percentage of time spent in the open arms. Animal Model: Naive adult male ICR mice,15 weeks old and weighing 25-35g Dosage: 2.5mg/kg,5.0mg/kg or 10mg/kg Administration: Intraperitoneal injection;2.5,5.0 or 10mg/kg;once a day;21 days Result: Exerted an anxiolytic-like effect in the elevated plus-maze test.
