2S,6S-Hydroxynorketamine Hydrochloride is a compound used in the treatment of neurological disorders such as depression, anxiety and various phobias involving social interaction. N-methyl-D-apartate receptor antagonist. Antidepressant.
(2S,6S)-Hydroxynorketamine hydrochlorideKetamine is a metabolite associated with increased locomotor activity and motor incoordination.It has been found that the NMDAR antagonist (R,S)-ketamine must be metabolized to (2S,6S;2R,6R)-hydroxynorketamine (HNK) to have antidepressant effects. The (2R,6R)-HNK enantiomer appears to be the enantiomer most responsible for antidepressant effects, while (2S,6S)-hydroxynorketamine was associated with increased locomotor activity and motor incoordination. (2S,6S)-HNK, was also found to increase the function of the mammalian target of rapamycin (mTOR) 2-fold at 0.05 nM. (2S,6S)-HNK and (2R,6R)-HNK both inhibited intracellular concentrations of D-serine, an endogenous NMDA receptor co-agonist, with IC50 values of 0.18 nM and 0.68 nM, respectively. Neither bind with high affinity to NMDA receptors, with Ki values of 21.19 μM and > 100 μM for (2S,6S)-HNK and (2R,6R)-HNK, respectively.
