CAS No. : 153205-46-0
MCE 国际站:Asimadoline
产品活性:Asimadoline (EMD-61753) 是一种口服有效的,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 5.6 nM 和 1.2 nM。Asimadoline 对血脑屏障的渗透性低,具有外周抗炎作用。Asimadoline 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。
研究领域:GPCR/G Protein | Neuronal Signaling
作用靶点:Opioid Receptor
In Vitro: Asimadoline (EMD-61753) has high selectively in κ: μ: δ opioid binding ratios of 1:501:498 in human recombinant receptors. The IC50 for Asimadoline 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 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 demonstrates spasmolytic action against 400 µM barium chloride in the rat duodenum (IC50=4.2 µM), suggesting that Asimadoline may block the direct stimulant effects of barium on smooth muscle through mechanisms that are not identified.
In Vivo: Asimadoline (EMD-61753; 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 is rapid and appears similar in animals and man. Asimadoline has peripheral anti-inflammatory actions that are partly mediated through increase in joint fluid substance P levels.
Treatment with Asimadoline (5 mg/kg/day; i.p.) produces marked (and sustained) attenuation of the disease with all three time regimes.
