Further, the inhibitory effect of proton pump activity was measured by the same method as in Experiment 1-2 of WO 94/14795. Namely, the proton pump activity stimulated by Mg ++ was used as a negative comparative group, and the activity stimulated by Mg^ and K + was used as a positive comparative group. The comparative compound was omeprazole. Test tubes were divided into 4 groups: Group 1 as negative comparative group(n=3), Group 2 as positive comparative group(n=3), Group 3(n=5x2) to be administered with the compound of the present invention and Group 4(n=5x2) to be administered with the comparative compound. The inhibitory effects of Groups 3 and 4 on proton pump activity were measured by employing the compound prepared in Examples and omeprazole, respectively, each of which was dissolved in dimethylsulfoxide at 5 different concentrations. To each of Groups 1, 2, 3 and 4 were added 100 /. 1 of magnesium chloride(40mM) dissolved in 40mM Tris-HCl buffer(pH 6.0) and 100 μ g of the enzyme source. The 50 μ 1 of potassium chloride(50mM) and 50 μ 1 of ammonium chloride(6mM) dissolved in 40mM Tris-HCl buffer(pH 6.0) were added to all groups except for group 1. 10 μ l of dimethylsulfoxide was added to each of Groups 1 and 2; and to Group 3 was added 10 μ l of dimethylsulfoxide solution prepared by dissolving compound of Example at 5 different concentration(n=5x2). To Group 4, 10 z l of the solution prepared by dissolving omeprazole in dimethylsulfoxide at 5 different concentration(37.6, 21.4, 12.2, 7.0 and 4.0 μ M) was added(n=5x2). 40mM Tris-HCl buffer(pH=6.0) was added thereto so as to make the total volume 400 μ l. Thereafter, the test tube of each Group were placed at 37 °C for 30 minutes for the preincubation. lOO μ l ATP solution (6.6mM) was added until the reaction volume became 500 l. After the reaction was carried out at 37 ° C for 30 minutes, 25% cold trichloroacetic acid was added to terminate the enzyme reaction. The released inorganic phosphate was measured by an automatic analyzer(Express 550, corning). The difference between Group 1 and Group 2 represents the proton pump activity activated by K + only. The IC 5 os of Group 3 and 4 were calculated from Litchfield-wilcoxon equation[see, e.g., J. Pharmacol. Exp. Ther.. 96, 99(1949)]. The concentrations of the test compounds inhibiting 50% of the proton pump activity are represented as IC 5 o in Table 1. Table 1.

Test 2 : Inhibition of gastric secretion In accordance with the method disclosed in Shay, H., et al., Gastroenterology 5 . 43-61(1945), Test 2 was carried out. Sprague-Dawly rats having a body weight of 170± 10g were divided into 3 groups(n=5) and deprived of food for 24 hours before the experiment with free access to water. Under ether anesthesia, the abdomen was incised, and the pylorus was ligated. As a comparative group, Group 1 was administered intraduodenally in a volume of 0.5ml/200g of 30% aqueous polyethylene glycol 400 solution. Groups 2 and 3 were administered intraduodenally with the compound of Example and omeprazole, respectively, each of which was suspended in 30% aqueous polyethylene glycol 400 solution at a concentration of 20mg/kg. After closing the abdominal cavity, the rats were placed for 5 hours and then killed by cervical dislocation. The stomach was extracted to obtain gastric juice. Tne gastric juice was centrifuged at l,000g to remove precipitates. The amount and acidity of the gastric juice were measured. Relative volumes, relative acid concentrations and relative acid outputs of the test compounds were calculated from equations( I ), (II ) and (IE) and the results are shown in Table 2. Relative volume = (the average amount of gastric juice of Group 1 - the average amount of gastric juice of Group 2) / (the average amount of gastric juice of Group 1 - the average amount of gastric juice of Group 3) — ( I ) Relative acid concerntration = (the average acidity of Group 1 - the average acidity of Group 2) / (the average acidity of Group 1 - the average acidity of Group 3) — (II) Relative acid output = (the total amount of acid output of Group 1 - the total amount of acid output of Group 2) / (the total amount of acid output of Group 1 - the total amount of acid output of Group 3) — (HI) The results are shown in Table 2.
