| 产品描述: | IP受体拮抗剂;an IP receptor antagonist;RO1138452是人类IP(前列环素)受体更有效的高亲和力配体和功能拮抗剂之一。RO1138452拮抗碳环前环素诱导的人类神经母细胞瘤腺苷酸环化酶的激活,以剂量依赖的方式阻断环状AMP的积累。同样,RO1138452抑制of化伊洛前列素与啮齿动物成神经细胞瘤细胞的结合,其K | i |约为1.5 nM。在大鼠中,水平为2-20 mg / kg时,RO1138452在标准抗伤害性试验中显示出明显的镇痛活性。;RO1138452 is one of the more potent high-affinity ligands and functional antagonists for the human IP (prostacyclin) receptor. RO1138452 antagonizes the carbaprostacyclin-induced activation of human neuroblastoma adenylate cyclase, blocking cyclic AMP accumulation in a dose-dependent manner. Likewise, RO1138452 inhibits the binding of tritiated iloprost to rodent neuroblastoma cells with a K|i|of about 1.5 nM. At levels between 2-20 mg/kg in rats, RO1138452 shows significant analgesic activity in standard antinociceptive assays. |
| 体内研究: |
RO1138452 是一种有效的选择性人和大鼠腹腔注射;受体拮抗剂,具有镇痛和抗炎作用。RO1138452 (1-10 mg/kg,iv) 显著减少乙酸引起的腹部收缩。RO1138452 (3-100 mg/kg,po) 显著减少 Carrageenan 诱导的机械痛觉过敏和水肿形成。RO1138452 (5 mg/kg,iv) 给药大鼠一小时后,总血浆浓度为 0.189 μg/mL,而游离血浆浓度计算为 0.009 μg/mL (28 nM)。 |
