(S)-(-)-3-Amino-1-hydroxypyrrolidin-2-one Chemical Properties,Uses,Production
Uses
(S)-(-)-HA-966 is an NMDA antagonist/partial agonist and is a potent sedative with ataxic action.
Biological Activity
Possesses potent sedative and ataxic action, probably through disruption of striatal dopaminergic mechanisms.
in vivo
(S)-(-)-HA 966 ((-)-HA 966; 3 and 5 mg/kg; i.p.) prevents restraint stress-induced dopamine utilization in both the medial prefrontal cortex and nucleus accumbens. (S)-(-)-HA 966 suppresses fear-induced behaviors: immobility and defecation[1].
(S)-(-)-HA 966 (3 mg/kg; i.p.) prevents locomotor sensitization without altering the acute motoric response elicited by cocaine[1].
(S)-(-)-HA 966 (5 mg/kg; i.p.) blocks acute cocaine-induced locomotion but resulted in sedation[1].
IC 50
