Chemical Name: (R)-(-)-2-(2-Chlorophenyl)-2-(methylamino)cyclohexanone hydrochloride
Biological Activity(R)-(-)-Ketamine hydrochloride is a NMDA antagonist (Ki = 1.4 μM); exhibits more potent and longer lasting antidepressant effects compared to its enantiomer (S)-ketamine in vivo. Also may not display the psychotomimetic or addictive side effects associated with (S)-ketamine. (R)-(-)-Ketamine hydrochloride upregulates KCNQ2 channels in mouse ventral hippocampal glutamatergic neurons in vitro and in vivo. It exerts its sustained antidepressant effetcs via KCNQ2 cell type specific regulation.
