Loperamide was tested on electrically-evoked contractions using a series of "in vitro" isolated preparations, in comparison with morphine, met-enkephalin, beta-endorphin, ethylketocyclazocine used as representative agonists of mu, delta, epsilon, kappa receptors respectively. The IC50 of loperamide on myenteric plexus longitudinal muscle of guinea pig ileum(More)
The effects of (S)-4-amino-5-[(4,4-dimethylcyclohexyl)amino]-5-oxo-pentanoic acid ((S)CR 2249), a new chemical entity selected among a series of glutamic acid derivatives, were investigated on N-methyl-D-aspartate (NMDA)-evoked release of [3H]noradrenaline from rat hippocampal slices. (S)CR 2249 facilitated glycine-mediated reversion of kynurenate(More)
The effects of S-4-amino-5-[4,4-dimethylcyclohexyl)amino]-5-oxopentanoic acid (CR 2249), a new entity selected from a new series of glutamic acid derivatives, has been investigated in different paradigms for screening nootropics. CR 2249 ameliorated the memory retention deficit produced by scopolamine in step-through-type passive avoidance in rats and by(More)
CR 1409, a glutaramic acid derivative with competitive cholecystokinin-antagonistic activity, was administered IP and evaluated in comparison with proglumide (the model CCK-receptor antagonist), gabexate (protease inhibitor) and PGE2 (cytoprotective) on two different models of experimental pancreatitis. Acute pancreatitis was induced in mice by six IP(More)
A surface-labeled lyophilized lymphocyte (sLL) preparation has been developed using human peripheral blood mononuclear cells prelabeled with a fluorescein isothiocyanate conjugated anti-CD4 monoclonal antibody. The sLL preparation is intended to be used as a reference material for CD4+ cell counting including the development of higher order reference(More)
Exposure assessment may be performed by ambient air monitoring and by biological monitoring (BM) of body fluids. The main analytical technique in BM, for the analysis of Volatile Organic Compounds (VOCs) in blood and urine, is the static head-space technique followed by capillary gas chromatography with different detectors. The actual measurement(More)
New glutaramic acid derivatives with cholecystokinin antagonistic activity were evaluated for their capacity to inhibit the satiety effect induced in the rat by intraperitoneal (i.p.) injection of cholecystokinin octapeptide (CCK-8). The most active compound, CR 1409, is about 4000 times more potent than proglumide when injected peripherally (i.p.). This(More)
