Alvimopan is a gastroprokinetic peripherally restricted mu-opioid receptor antagonist (MOR). It has a favorable kinetic activity (0.2 ng/ml) and dissociates more slowly than most other ligands.
| Mechanism of Action | Alvimopan competitively binds to the mu-opioid receptor in the gastrointestinal tract. It has a low systemic absorption and a high affinity for mu-opioid receptors. This compound assists gastrointestinal motility dysfunction. |
| Purity Level | 98.0%-102.0% (anhydrous basis)02.0% (anhydrous basis) |
| Eukaryotic Cell Culture Applications | In vitro studies with Alvimopan using CHO cell membranes revealed that it inhibited GTP binding with an IC50 of 1.7 nM. |
| Molecular Formula | C25H32N2O4 |
| Solubility | Slightly soluble in DMSO. Very slightly soluble in water. |
