包装规格：5mg 10mg 25mg 50mg 100mg in glass bottle
产品简介：Niraparib (MK-4827) tosylate hydrate 是高效的，具有生物口服利用度的 PARP1 和 PARP2 抑制剂，IC50 分别为 3.8 nM 和 2.1 nM。Niraparib tosylate hydrate 抑制 DNA 损伤修复，诱导凋亡 (apoptosis) 并具有抗肿瘤活性。
储备液保存：-80°C, 6 months -20°C, 1 month (sealed storage, away from moisture)
靶点：PARP-2: 2.1 nM (IC50) PARP-1: 3.8 nM (IC50) V-PARP: 330 nM (IC50) TANK-1：570 nM (IC50) PARP-3：1300 nM (IC50)
体外研究：Niraparib (MK-4827) tosylate hydrate inhibits PARP activity with EC50=4 nM and EC90=45 nM in a whole cell assay. Niraparib tosylate hydrate inhibits proliferation of cancer cells with mutant BRCA-1 and BRCA-2 with CC50 in the 10-100 nM range. Niraparib tosylate hydrate displays excellent PARP 1 and 2 inhibition with IC50=3.8 and 2.1 nM, respectively, and in a whole cell assay. Niraparib tosylate hydrate inhibits PARP within 15 minutes of treatment reaching about 85% inhibition in the A549 cells at 1 h and about 55% inhibition at 1 h for the H1299 cells.
体内研究：Niraparib (MK-4827) tosylate hydrate is well tolerated and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer. Niraparib (MK-4827) tosylate hydrate is well tolerated in vivo and demonstrates efficacy as a single agent in a xenograft model of BRCA-1 deficient cancer. Niraparib (MK-4827) tosylate hydrate is characterized by acceptable pharmacokinetics in rats with plasma clearance of 28 (mL/min)/kg, very high volume of distribution (Vdss=6.9 L/kg), long terminal half-life (t1/2=3.4 h), and excellent bioavailability, F=65%. Niraparib (MK-4827) tosylate hydrate enhances radiation response of p53 mutant Calu-6 tumor in both cases, with the single daily dose of 50 mg/kg being more effective than 25 mg/kg given twice daily.
