Stimulation of cannabinoid receptors by exogenous agonists, such as CP55940 or WIN 55,212-2, causes inhibition of the electrically-evoked release of acetylcholine and motor activity in the guinea-pig ileum (see review by Pertwee, 1999), and these effects are competitively antagonized by the specific CB receptor antagonist SR141716A (Pertwee et al., 1996; Coutts and Pertwee, 1997).
Inhibition by CP55940 of the electrically-evoked release of [

CP55,940 induced quench of fura-2 fluorescence by Mn2+ (50 microM), suggesting the presence of Ca2+ influx across the plasma membrane.
CP55,940 (10 microM)-induced [Ca2+]i increase in Ca(2+)-free medium was inhibited by 84% by pretreatment with 1 microM thapsigargin, an endoplasmic reticulum Ca2+ pump inhibitor.
CP55,940 (20 microM) did not induce acute cell death after incubation for 30 min as assayed by trypan blue exclusion.

 Director's Report 5/02 - Basic Research
Treatment of neonatal rat brain cortical microglial cells with the cannabinoid paired enantiomers CP55940 and CP56667 resulted in a stereoselective differential effect on inducible NO production.
The analog CP55940 exerted a dose-dependent inhibition of interferon gamma (IFN gamma)/bacterial lipopolysaccharide (LPS)-inducible NO production which was significantly greater than that exerted by CP56667.
Collectively, these results indicate that the cannabinoid analog CP55940 selectively inhibits inducible NO production by microglial cells and that this inhibition is effected, at least in part, through the CB1 receptor.

The cannabinoid CB1 receptor agonist, CP55940, inhibits vesicular release evoked with 2 Hz stimulation.
CP55940 slowed the release elicited by 2 Hz stimulation, and this was prevented by AM251.

Thus, levels of anandamide, although not of 2-arachidonoyl glycerol or palmitoylethanolamide, increased in the small intestine in response to cholera toxin as did the expression of CB receptors.
The intestinal fluid accumulation induced by cholera toxin was increased by SR141716A but not by SR144528 and was reduced by CP55940 and ACEA pretreatment in a manner that was sensitive to antagonism by SR141716A but not SR144528.

EPSCs were evoked in patch-clamped layer V pyramidal cells by stimulation of layer V afferents.
Monosynaptic EPSCs were strongly depressed by bath application (1?M) of the cannabinoid receptors agonists WIN55212-2 (-50,4 ± 8,8 %) and CP55940 (-42,4 ± 10,9 %).
Unexpectedly, SR141716A alone produced a significant increase of glutamatergic synaptic transmission (+46,9 ± 11,2 %) which could be partly reversed by WIN55212-2.

In addition, binding studies with radioligands for 5-HT3 as well as for cannabinoid CB1 and CB2 receptors were carried out.
In competition experiments on membranes of HEK293 cells transfected with the h5-HT3A receptor cDNA, WIN55,212-2, CP55940, anandamide and SR141716A did not affect [3H]-GR65630 binding, but 5-HT caused a concentration dependent-inhibition.
