Asimadoline
Asimadoline (EMD-61753) is an orally active, selective and peripherally active κ-opioid agonist with IC50s 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).

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[1].
Asimadoline has affinity to sodium and L type Ca2+ ion channels at IC50 concentrations 150 to 800 fold the IC50 for the κ receptors[1].
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[1].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
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[1].
Treatment with Asimadoline (5 mg/kg/day; i.p.) produces marked (and sustained) attenuation of the disease with all three time regimes[2].
