Cannabinoid receptor agonists inhibit electrically evoked isometric contractions of the myenteric plexus--longitudinal muscle preparation of the guinea-pig small intestine (MPLM), probably by reducing release of acetylcholine (ACh) through the activation of prejunctional CB1 receptors. As CB1
1. Methyl arachidonyl fluorophosphonate (MAFP) (1 microM) significantly attenuated the ability of WIN 55,212-2, CP 55,940, (-)-delta 9-tetrahydrocannabinol (THC), nabilone and (R)-(+)-arachidonoyl-1'-hydroxy-2'-propylamide (methanandamide) to inhibit electrically-evoked isometric contractions of the
1. The dose-related inhibition of the twitch responses of the myenteric plexus-longitudinal muscle preparation of the guinea-pig small intestine by cannabinoid (CB) agonists, (+)-WIN 55212 and CP 55940 during stimulation at 0.1 Hz with supramaximal voltage was confirmed. These agonists inhibited
1. CP 50,556, CP 55,940, nabilone, CP 56,667, delta 9 -tetrahydrocannabinol (THC) and cannabinol each inhibited electrically-evoked contractions of the myenteric plexus-longitudinal muscle preparation of guinea-pig small intestine in a concentration-related manner. The IC50 values of these
