The histamine H(3) receptor shows high degree of stereoselectivity for histamine analogues branched in the side chain. The hypothesis that gastroprotection by (R)-alpha-methylhistamine could be H(3) receptor-mediated was tested by comparing the effec

1. The histamine H2 receptor agonists, dimaprit, impromidine, amthamine, and several dimaprit- and impromidine-analogues were investigated for their spasmolytic activity on the guinea pig duodenum, precontracted with acetylcholine or KCl. 2. Almost a

The effect of a new histamine H2-receptor antagonist derived from the lamtidine molecule and containing a nitric oxide (NO)-donor furoxan moiety (derivative 1) was studied for its gastric antisecretory activity and for a possible gastroprotective eff

(R)-alpha-Methylhistamine, a selective agonist of histamine H3 receptors, prevents macroscopically visible gastric lesions by absolute ethanol in the rat. A further insight into its activity was the aim of our study. Rats were given saline or (R)-alp

The hypothesis that prejunctional histamine H3 receptors and alpha-2 adrenoceptors interact with each other was assessed on the cholinergic transmission of the guinea pig duodenum. Specific agonists acting at histamine H3 receptors, alpha-2 adrenocep

The effect of the histamine H3 receptor agonist (R) alpha-methylhistamine on duodenal bicarbonate secretion was investigated in the anaesthetized rat. (R) alpha-methylhistamine (3-30 mumol/kg i.v.) caused a dose-dependent increase in alkaline secreti

Fedotozine was rested in colonic strips removed during surgery from patients suffering from different diseases of the colon; the effects were compared to those of morphine and of the selective opiate agonist U-69593. Fedotozine did not affect the spo

The ability of (R)-alpha-methylhistamine, the selective agonist of histamine H3 receptors, to reduce ethanol-induced gastric damage was examined in the rat. (R)-alpha-methylhistamine (1-100 mg/kg intragastrically) caused a dose-related reduction in t
