The effects of ten days' oral treatment with 200 mg/kg/d of 4-(3,4,5-trimethoxythiobenzoyl)tetrahydro-1,4-oxazine (trithiozine) on the mechanical responses of rat stomach in vitro have been studied. Gastric muscular excitation due to vagal stimulation was partially reduced in the trithiozine-pretreated animals, while the amount of acetylcholine (Ach) released both at rest conditions and in response to field stimulation was similar in both controls and drug-pretreated rats. Also muscular responses induced by dopamine (DA) and by serotonin (5-HT) were of similar degree in both groups of rats. On the contrary, the nonadrenergic and non-cholinergic inhibitory response evoked by vagal stimulation in the presence of muscarinic and alpha- and beta-adrenergic receptor blockade, respectively, was enhanced in the drug-pretreated animals. Moreover, trithiozine pretreatment caused an increase of spontaneous motor activity and a remarkable degree of potentiation of the contractile response to prostaglandins (PGs), both exogenously applied or endogenously released by ATP. Our results give further evidence that trithiozine has no anticholinergic activity and that some therapeutic properties of the molecule could be accounted for by an involvement of endogenous PGs.
