  • Title: Behavioral activity of 1S,3R-ACPD, an agonist of metabotropic glutamate receptors.
    Author: Zalewska A, Wiśniewski K.
    Journal: Pol J Pharmacol; 1997 Aug; 49(4):239-48. PubMed ID: 9437767.
    Abstract:
    The influence of intracerebroventricular (i.c.v.) injections of 1-aminocyclopentane-1,3-dicarboxylic acid (1S,3R-ACPD), an agonist of metabotropic glutamate receptors, on the activity of the central nervous system was examined in rats. 1S,3R-ACPD at the i.c.v. doses of 100 and 200 nmole significantly decreased apomorphine-induced stereotypy, and at a dose 200 nmole significantly diminished catalepsy caused by haloperidol, two behavioral symptoms controlled mainly by central dopaminergic system. The tested compound had no influence on the locomotor and exploratory activity of rats estimated in open field. 1S,3R-ACPD significantly improved acquisition at the i.c.v. dose of 100 nmole, and consolidation of information at the i.c.v. doses of 100 and 200 nmole. The tested compound had no influence on retention processes in passive avoidance situation. This compound also did not improve recognition memory tested in the object recognition test. These results indicated that 1S,3R-ACPD improved memory motivated affectively but had no influence on recognition memory and the diminished dopaminergic transmission.
