Sigma 1 Receptor 17.4 nM (IC50) |
Sigma 2 Receptor 1784 nM (IC50) |
Exposure of the neurons to H2O2 induced cell death, while pretreatment with Cutamesine inhibits neuronal cell death. Cutamesine also reduces the activation of the MAPK/ERK pathway and down-regulated the ionotropic glutamate receptor, GluR1[2].
MedChemExpress (MCE) has not independently confirmed the accuracy of these methods. They are for reference only.
A single injection of 1 mg/kg i.p. of Cutamesine produced a significant decrease and increase in the number of spontaneously active SNC and VTA DA neurons, respectively[3].
The repeated administration (one injection per day for 21 days) of 0.3 and 1 mg/kg i.p. of Cutamesine produced a significant increase in the number of spontaneously active VTA DA neurons[3].
