RO1138452
CAS No. : 221529-58-4
MCE 国际站:RO1138452
产品活性:RO1138452 是一种有效的选择性前列环素 IP (prostacyclin) 受体拮抗剂。RO1138452 对 IP 受体具有高的亲和力。在人血小板中,pKi 值为 9.3±0.1; 在重组 IP 受体系统中,pKi 值为 8.7±0.06。
研究领域:GPCR/G Protein
作用靶点:Prostaglandin Receptor
In Vitro: RO1138452 is IP receptor antagonist. The pIC50 values of RO1138452 in attenuating cAMP accumulation is 7.0±0.07. Functional antagonism of RO1138452 is studied by measuring inhibition of carbaprostacyclin-induced cAMP accumulation in CHO-K1 cells stably expressing the human IP receptor. The antagonist affinity (pKi) of RO1138452 is 9.0±0.06. Selectivity profiles for RO1138452 are determined via a panel of receptor binding and enzyme assays. RO1138452 displays affinity at imidazoline2 (I2) (8.3) and platelet activating factor (PAF) (7.9) receptors. RO1138452 (10 pM-10 μM) added to cells concurrently with a fixed concentration of Taprostene (1 μM) prevents, in a concentration-dependent manner, the inhibition of CXCL9 and CXCL10 release, with p[A]50 (molar) values of -8.73±0.11 and -8.47±0.16 (p>0.05), respectively.
In Vivo: RO1138452 is a potent and selective antagonist for both human and rat IP receptors and that is possesses analgesic and anti-inflammatory potential. RO1138452 (1-10 mg/kg, i.v.) significantly reduces acetic acid-induced abdominal constrictions. RO1138452 (3-100 mg/kg, p.o.) significantly reduces carrageenan-induced mechanical hyperalgesia and edema formation. One hour after administration of RO1138452 (5 mg/kg, i.v.) to rats, the total plasma concentration is 0.189 μg/mL, whereas the free plasma concentrations is calculated to be 0.009 μg/mL (28 nM).

的产物。这些酸性和酚类物质能结合血清中的钙并改变其浓度,导致错误的结果。 因此,当使用简单的 SDI 水用于供给临床生化仪时,可能会出现上述两个问题: ➤ 钙泄漏,会干扰血钙浓度 ➤ 存在大量有机酸,可通过结合而改变血钙浓度 所以,对于一个成熟的水纯化工艺通常应该包括反渗透(RO)和电去离子(EDI)的组合,RO-EDI 的组合能确保恒定的水质,而不会出现使用 SDI 水时水的离子纯度下降的情况。另外,RO-EDI 能非常有效去除大量有机酸(腐殖酸和富里酸),减少分子与钙的结合。
性T细胞表型的异同点。可以看出,第一,所有的记忆性T细胞(CD4TCM、CD4TEM、CD8TCM和CD8TEM)皆为CD45RO+,但CD8TCM中有一个亚群为CD45RO-CD45RA+,特称为CD8TEMRA。第二,对CCR7和CD62L这两种表面分子,只有TCM为阳性,而TEM为阴性,这也是表9―5所展示的情况。CD27和CD28的表达格局比较复杂,虽主要于表达在TCM,但也有例外。至于其他一些标志的表达格局,则因细胞亚群的不同而呈现变化。 人体记忆
