包装规格:1mg 5mg 10mg 25mg 50mg 100mg in glass bottle
产品简介:一种口服有效的,选择性的,具有周边活性的κ-opioid激动剂,对豚鼠和人重组κ-opioid的IC50s分别为5.6nM和1.2nM。Asimadoline hydrochloride对血脑屏障的渗透性低,具有外周抗炎作用。Asimadoline hydrochloride可改善糖尿病大鼠的异常性疼痛,并具有用于肠易激综合征(IBS)研究的潜力。
溶解性:溶于DMSO(240mg/mL超声)
储备液保存:-80°C, 6 months -20°C, 1 month (sealed storage, away from moisture)
体内实验:1、请依序添加每种溶剂: 10% DMSO→40% PEG300→5% Tween-80→45% Saline Solubility: ≥ 6 mg/mL (13.30 mM); 澄清溶液 此方案可获得 ≥ 6 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 60.0 mg/mL 的澄清 DMSO 储备液加到 400 μL PEG300 中,混合均匀;再向上述体系中加入 50 μL Tween-80,混合均匀;然后再继续加入 450 μL 生理盐水 定容至 1 mL。 2、请依序添加每种溶剂: 10% DMSO→90% (20% SBE-β-CD in Saline) Solubility: ≥ 6 mg/mL (13.30 mM); 澄清溶液 此方案可获得 ≥ 6 mg/mL(饱和度未知)的澄清溶液。 以 1 mL 工作液为例,取 100 μL 60.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中,混合均匀。 3、请依序添加每种溶剂: 10% DMSO→90% Corn Oil Solubility: ≥ 6 mg/mL (13.30 mM); 澄清溶液 此方案可获得 ≥ 6 mg/mL(饱和度未知)的澄清溶液,此方案实验周期在半个月以上的动物实验酌情使用。 以 1 mL 工作液为例,取 100 μL 60.0 mg/mL 的澄清 DMSO 储备液加到 900 μL玉米油中,混合均匀。 <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。
靶点:IC50: 5.6 nM (guinea pig κ opioid);1.2 nM (human recombinant κ opioid)
体外研究:Asimadoline (EMD-61753) hydrochloride has high selectively in κ: μ: δ opioid binding ratios of 1:501:498 in human recombinant receptors. The IC50 for Asimadoline hydrochloride binding to μ-opioid receptors is 3 µM and to δ-opioid receptors is 0.7 µM. The IC50 values for D1, D2, kainate, σ, PCP/NMDA, H1, α1, α2, M1/M2, glycine, 5HT1A, 5HT1C, 5HT1D, 5HT2, 5HT3, AMPA and kainate/AMPA receptors are all >10 µM. Asimadoline hydrochloride has affinity to sodium and L type Ca2+ ion channels at IC50 concentrations 150 to 800 fold the IC50 for the κ receptors. At high concentrations, Asimadoline hydrochloride demonstrates spasmolytic action against 400 µM barium chloride in the rat duodenum (IC50=4.2 µM), suggesting that Asimadoline hydrochloride may block the direct stimulant effects of barium on smooth muscle through mechanismsthat are not identified.
体内研究:Asimadoline (EMD-61753 hydrochloride; 1, 5, 15 mg/kg; s.c.) acutely ameliorates both formalin-evoked hyperalgesia and tactile allodynia in diabetic rats. The absorption rate following oral administration is 80% in rats and >90% in dogs and monkeys. The metabolism of Asimadoline hydrochloride is rapid and appears similar in animals and man. Asimadoline hydrochloride has peripheral anti-inflammatory actions that are partly mediated through increase in joint fluid substance P levels. Treatment with Asimadoline hydrochloride (5 mg/kg/day; i.p.) produces marked (and sustained) attenuation of the disease with all three time regimes.
