The biological study of mutual-through type (I) compound shows these compound biologically actives, and promptly they have significant antiulcer action, cytoprotection for example, and in addition, they also have significant anti-microbial effect.
Therefore, the invention still further relates to methods of treatment, this method comprise to Mammals (comprising the people) organism with separately or with the logical formula I compound (wherein R and n are as defined above) of pharmaceutical compositions drug treatment effective dose to prevent and/or treat the various ulcers of ESD.
Therapeutic activity with the logical formula I compound of following method research.
The research of the gastric damage that brings out by acidiferous alcohol.
Method [Gastroenterology 77,761-767(1979)] according to A.Robert is tested.Every heavy female rats of 120 to 150g is used for these experiments in fasting after 24 hours.To treat that substances adds in the stomach of animal by stomach tube as 80% tween suspension.After half an hour, the acidiferous alcohol of every 100g body weight 0.5ml is applied in the stomach of animal by stomach tube.Put to death animal after 1 hour, take out its stomach, and cut along greater gastric curvature.Measure reddish-brown striped (going out blood injury) and calculate the average total length of a stomach.The activity and the control group of test compound are compared.Behind oral administration, the ED that the The compounds of this invention described in the embodiment 1 shows
50Value is 0.3mg/kg.
The test of Shay ' s ulcer
According to Gastroenterology 5b, 5-13(1945) described method is tested.With the fasting 24 hours in the grid cage of every heavy 120 to 150g male H-Wister mouse.Drink water the pylorus of ligation animal under the slight anesthesia of ether arbitrarily to animal.After 4 hours, put to death animal, take out its stomach, and measure the volume and the pH value of stomach, use the output of titration measuring HCl in some cases with excessive ether.
Found that the ED of The compounds of this invention behind oral administration
50Value is 26mg/kg.
The activity of anti-helicobacter pylori
With agar diffusion and agar dilution, in activity from the isolated helicobacter pylori culture research of patient's various ulcer logical formula I compound of the present invention.
Minimum inhibition concentration (MIC) value of having found embodiment 1 compound is 0.9/ μ g/ml.
The result can be clear that by these pharmacology, and logical formula I compound of the present invention has good antiulcer agent performance, and the effect of significant anti-helicobacter pylori.
New logical formula I compound (wherein R and n are as defined above) of the present invention prepares by following method:
Use logical formula III alcohol:
