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。

Asimadoline (EMD-61753) is an orally active, selective and peripherally active κ-opioid agonist with IC 50 s of 5.6 nM (guinea pig) and 1.2 nM (human recombinant). Asimadoline has low permeability across the blood brain barrier and has peripheral anti-inflammatory actions. Asimadoline ameliorates allodynia in diabetic rats and has the potential for irritable bowel syndrome (IBS).

IC50: 5.6 nM (guinea pig κ opioid), 1.2 nM (human recombinant κ opioid)

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 Ca 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.

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.
has not independently confirmed the accuracy of these methods. They are for reference only.
