What is ASIMADOLINE?
The Uses of ASIMADOLINE
Acimadolin is a K-opioid agonist that raises the sensitivity threshold in patients with irritable bowel syndrome (IBS), barely crosses the blood-brain barrier, and is well tolerated. It cannot significantly improve the pain threshold of patients, Can significantly reduce pain intensity.
Biological Activity
Asimadoline (EMD-61753) is an orally active, selective, peripherally active κ-opioid agonist with IC50s of 5.6 nM and 1.2 nM for guinea pig and human recombinant κ-opioid, respectively. It has low permeability to the blood-brain barrier and has peripheral anti-inflammatory effects. Also Asimadoline improves allodynia in diabetic rats and has potential for irritable bowel syndrome (IBS) research.
in vitro
Asimadoline (EMD-61753) has high selectively in κ: μ: δ opioid binding ratios of 1:501:498 in human recombinant receptors. The IC 50 for Asimadoline binding to μ -opioid receptors is 3 μM and to δ-opioid receptors is 0.7 μM. The IC 50 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.
It has affinity to sodium and L type Ca 2+ ion channels at IC 50 concentrations 150 to 800 fold the IC 50 for the κ receptors.
At high concentrations, Asimadoline demonstrates spasmolytic action against 400 μM barium chloride in the rat duodenum (IC 50 =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; sc) 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.
