产品描述 | Endomorphin 1 is a high affinity and selective agonist of the μ-opioid receptor and displays reasonable affinities for kappa3 binding sites (Ki: 20~30 nM). |
靶点活性 | κ3 opioid receptor:20-30 nM (Ki) |
体外活性 | Endomorphin是一种内源性阿片肽,也是两种Endomorphins之一。它是μ-阿片受体的高亲和力、高选择性激动剂,并且与Endomorphin 2一同作用。Endomorphin 1和Endomorphin 2都能强效地竞争μ1与μ2受体位点。Endomorphins对delta或kappa1结合位点的亲和力很低,其Ki值均大于500 nM。 |
体内活性 | Endomorphin 1和Endomorphin 2均为有效的镇痛剂,其效果分别在10分钟和15分钟达到顶峰。所有后续研究均在达到最大效应时进行。这两种化合物在脊髓上方和脊髓内均完全活跃,且没有出现效应上限。Endomorphin 1和Endomorphin 2的作用特征与吗啡相似。在对CD-1小鼠产生超过70%镇痛效果的剂量下,这两种化合物在CXBK小鼠中均无镇痛活性。 |
激酶实验 | 125I-Endomorphin 1 or 125I-Endomorphin 2 binding (0.2 nM) is performed in potassium phosphate buffer (50 mM, pH 7.4; 0.5 mL) with MgCl2 (5 mM) at a tissue concentration of 10 mg wet weight/mL for brains or 0.06 mg protein/mL for MOR-1/CHO cells. Specific binding is determined in the presence and absence of either 1 μM of the corresponding unlabeled peptide. The entire mixture is then incubated at 25°C for 1 hr and filtered over no. 32 glass fiber filters which have been presoaked for 1 hr in 0.5% polyethyleneimine and washed twice with ice-cold Tris buffer using a Brandel cell harvester. The filters are then counted on a Packard Cobra gamma counter. The other opioid receptor binding assays are performed. |
动物实验 | Groups of mice are treated i.c.v. with Endomorphin 1 (12 μg) or Endomorphin 2 (3 μg) 15 min before a 0.5-cc charcoal meal (2.5% gum tragacanth,10% activated charcoal in water). The mice are killed 30 min later and the distance the charcoal traveled is measured. |

请在以下方框中输入您的动物实验信息后点击计算,可以得到母液配置方法和体内配方的制备方法: 比如您的给药剂量是10 mg/kg,每只动物体重20 g,给药体积100 μL,一共给药动物10 只,您使用的配方为5% DMSO+30% PEG300+5% Tween 80+60% ddH2O。那么您的工作液浓度为2 mg/mL。
母液配置方法:2 mg 药物溶于 50 μL DMSO (母液浓度为 40 mg/mL), 如您需要配置的浓度超过该产品的溶解度,请先与我们联系。
体内配方的制备方法:取 50 μL DMSO 主液,加入 300 μL PEG300, 混匀澄清,再加 50 μL Tween 80,混匀澄清,再加 600 μL ddH2O, 混匀澄清。
