Hypolocomotion induced by peripheral or central injection of CCK in the mouse is blocked by the CCKA receptor antagonist devazepide but not by the CCKB receptor antagonist L-365,260.

Abstract:

The pharmacological mechanisms underlying the hypolocomotion induced by intraperitoneal (i.p.) and intracerebroventricular (i.c.v.) injections of cholecystokinin octapeptide sulphated (CCK) in the mouse were examined using selective CCKA and CCKB receptor antagonists. Locomotor activity was measured in photocell cages. CCK (10 micrograms/kg i.p.) significantly reduced activity in mice tested in the afternoon but not in the morning, indicating a circadian variation in the effect of the peptide...
