The postganglionic sympathetic nerves of the isolated rat stomach were electrically stimulated twice at 1 Hz for 1 min. Prostaglandin E2and ONO-AE-248 (16S-9-deoxy-9β-chloro-15-deoxy-16-hyfroxy-17,17-trimethylene-19,20-didehydro prostaglandin F2) (an EP3receptor agonist) reduced the evoked noradrenaline release, while ONO-DI-004 (17S-2,5-ethano-6-oxo-17,20-dimethyl prostaglandin E1) (an EP1receptor agonist), ONO-AE1-259-01 (11,15-O-dimethyl prostaglandin E2) (an EP2receptor agonist) and ONO-AE1-329 [16-(3-methoxymethyl)phenyl-ω-tetranor-3,7-dithia prostaglandin E1] (an EP4receptor agonist) had no effect. U-46619 (9,11-dideoxy-9α,11α-methanoepoxy prostaglandin F2α) and I-BOP (7-[3-[3-hydroxy-4-(4-iodophenoxy)-1-butenyl]-7-oxabicyclo[2,2,1] hept-2-yl]-,[1S[1α,2α(Z),3β(1E,3S)4α]]-5-heptenoic acid) (TP receptor agonists) also reduced the noradrenaline release and these inhibitory effects were abolished by SQ-29548 (7-[3-[[2-[(phenylamino) carbonyl] hydrazino]methyl]-7-oxabicyclo[2,2,1]hept-2-yl][1S(1α,2α(Z), 3α,4α]-5-heptenoic acid) (a TP receptor antagonist). The inhibitory effect of U-46619, but not ONO-AE-248, was abolished by pertussis toxin. These results suggest that the prostanoid EP3and TP receptors mediate the inhibition of gastric noradrenaline release; TP, but not EP3, receptor-mediated inhibition is mediated by a pertussis toxin-sensitive mechanism in rats.
