R. Schreiber et al., LY354740 affects startle responding but not sensorimotor gating or discriminative effects of phencyclidine, EUR J PHARM, 388(2), 2000, pp. R3-R4
LY354740 {(1S,2S,5R,6S)-2-aminobicyclo[3.1.0]hexane-2,6-dicarboxylate monoh
ydrate}, a selective group II metabotropic glutamate (mGlu) receptor agonis
t, was recently reported to attenuate the behavioral effects of phencyclidi
ne (PCP) in rats. In the present study, LY354740 failed to attenuate the di
scriminative stimulus properties of PCP and its disruption of prepulse inhi
bition of the acoustic startle response, at a dose range which decreased st
artle responding. The suggestion that mGlu group II receptor activation ind
uces antipsychotic effects may be premature. (C) 2000 Elsevier Science B.V.
