Ki: 2 nM (Vesicular acetylcholine transport), 26 nM (σ1 receptors) and 34 nM (σ2 receptors)
The pharmacological actions of (±)-Vesamicol have been attributed to inhibition of acetylcholine transport into synaptic vesicles and the subsequent quantal release of acetylcholine.
(±)-Vesamicol (3 mg/kg; intraperitoneal injection; once; male Wistar rats) treatment increases the levels of cytosolic acetylcholine (ACh) in all regions of the brain, while those of vesicular ACh decreased in all regions except for the striatum.
| Animal Model: | Male Wistar rats (120-300 g) |
| Dosage: | 3 mg/kg |
| Administration: | Intraperitoneal injection; once |
| Result: | The levels of cytosolic acetylcholine (ACh) increased in all regions of the brain, while those of vesicular ACh decreased in all regions except for the striatum. |
