(R)-(+)-HA-966

(R)-(+)-HA-966 ((+)-HA-966) is a partial agonist/antagonist of glycine site of the N-methyl-D-aspartate (NMDA) receptor complex. (R)-(+)-HA-966 selectively blocks the activation of the mesolimbic dopamine system by amphetamine[1][2]. (R)-(+)-HA-966 can cross the blood-brain barrier and has the potential for neuropathic and acute pain[3].
