Description: FIELD OF THE INVENTION The present invention relates to alkylenediamine derivatives having activity against Helicobacter pylori and anti-ulcer activity. BACKGROUND OF THE INVENTION Various theories have been proposed, as to the cause of ulcers in human. In particular, stress, and the taking ofnon-steroidal anti-inflammatory drugs for rheumatic diseases, are closely related to ulcer formation, mainly due to increased gastric acid secretion.

WIS: Restraint and Water Immersion Stress-Induced Ulcer Inhibition Test i)Meaning The degree of inhibition of the stress ulcer formation is tested. ii)Method Male Crj:SD or Slc:SD rats (6 to 7- week- old) were fasted overnight, but allowed free access to water. Each group has 5 to 8 of these rats. The sample compound was dissolved or suspended in an aqueous solution of 0.3% sodium carboxymethylcellulose or 0.05% Tween 80 and then was orally administered (100 mg/10 ml/kg). To a control group, the vehicle was administered. 10 minutes later, the rats were placed in a stress cage and immersed to the level of xipfoid process in a water bath (21°C) for 7 hours. At the end of the stress, the rats were sacrificed by inhalation of ether or carbon dioxide. Then, the stomach of each was removed, inflated by injecting 10 ml of 5% formalin neutral buffer solution, and immersed in 1% formalin neutral buffer solution for 30 minutes or more to be fixed. The stomach was incised along the greater curvature and then the length of each erosion in the glandular portion was determined under dissecting microscope. The sum of the length of erosions per stomach was defined as ulcer index (UI). iii)Judgment Standard The effect obtained when 100 mg/kg of the sample compound had been administered was expressed as ulcer formation inhibitory rate (%) as follows: ulcer formation inhibitory rate (%) = (1- (UI in sample group/UI in control group)) × 100 VOL. TAO: Acid Secretion Inhibition Test In Vivo i)Meaning Inhibitory effect on acid secretion in vivo is confirmed. ii)Method Male Crj:Donryu rats (7-week-old) were fasted overnight but allowed free access to water. In each group, 8 to 10 of these rats were used under urethane anesthesia (1.25 g/kg). The sample compound dissolved or suspended in an aqueous solution of 0.5% sodium carboxymethylcellulose or U.05% Tween 80 was orally administered (100 mg/10 ml/kg). 30 minutes later, the abdomen of each was incised and the pylorus was ligated. 30 minutes after the ligation, 30 mg/kg of histamine dissolved in physiological saline was subcutaneously administered and, 3 hours thereafter, the rat was sacrificed with carbon dioxide. Immediately thereafter, each stomach was removed and the gastric contents were collected and each volume was determined. The total acid output was determined by titration of the gastric juice with 0.1N NaOH. iii)Judgment Standard With respect to the gastric juice volume (VOL) and the total acid output (TAO), the effects obtained when 100 mg/kg of the sample compound, had been administered were expressed as their respective inhibitory rates (%) as follows: each inhibitory rate (%) = (1- (value in sample group/ value in control group)) X 100 CAP: Acid Secretion Inhibition Test In Vitro i)Meaning The acid secretion inhibitory activity in a cell level is studied. It can also be used for studying the mechanism of the effect. ii)Method ii- a) Preparation of isolated gastric fundus gland suspension First, an isolated gastric fundic gland sample was prepared. Namely, a male Japanese White rabbit (2.5 to 3 kg) was anesthetized to death with Nembutal™ and then the abdomen was incised. Immediately thereafter, the stomach was removed and, after its pyloric and cardiac antrum were severed, incised along its greater curvature into two sheets. The gastric contents adhering to the mucosal surface was washed out with ice-cooled PBS (-) and then carefully washed therein. The gastric wall was spread on a cork board with its mucosal surface facing up and the feed and mucus thereon were completely removed with sterile gauze. The mucosa was separated therefrom by a spatula and then collected in ice-cooled PBS (-). After being washed twice with PBS (-), the mucosa was minced into 2-3mm 3 pieces by scissors. These pieces were further washed twice with a nutrient solution. The nutrient solution comprises 132.4 mM of NaCl, 5.4 mM of KCl, 5 mM of Na 2 HPO 4 • 12H 2 O, 1 mM of NaH 2 PO 4 • 2H 2 O, 1.2 mM of MgSO 4 , 1 mM of CaCl 2 , 25 mM of HEPES, 2 mg/ml of glucose, and 1 mg/ml of BSA. Into 70 ml of the nutrient solution containing 1 mg/ml of collagenase, minced mucosal pieces were dispersed and intensely stirred in a conical flask with a stirrer at 37°C for 40 to 60 minutes. During this period, 100% O 2 was sprayed on the nutrient solution surface and the pH was appropriately measured such that it was immediately adjusted to pH 7.4, when the value was therebelow, with a base. The nutrient solution was added to the reaction solution so as to attain the total amount of about 200 ml. Alter being filtered through a mesh, the suspension was divisionally introduced into 50 ml centrifuge tubes and left for 15 minutes such that gastric fundic gland was deposited. The supernatant was repeatedly removed by an aspirator, dispersed in the nutrient solution, and then left such that the gastric fundic gland was washed three times. At this time, without using a pipette, the suspension was alternately introduced into two centrifuge tubes so as to effect dispersion. The number of cells was counted under microscope and adjusted to 1.6 × 10 6 cells/ml. ii-b) [ 14 C]-aminopyrine uptake test Then, [ 14 C]-aminogyrine uptake test was performed. After an Eppendorf tube was weighed, 10 µ l (final concentration: 10 -5 M) of histamine dissolved in the above-mentioned nutrient solution, 10 µ l (final concentration: 10 -5 M) of the test compound dissolved in DMSO, and 10 µ (final concentration: 0.05 µ Ci/ml) of [ 14 C]-aminopyrine diluted with the nutrient solution were introduced therein and then 970 µ l of the isolated gastric fundic gland suspension prepared above was added thereto. Subsequently, this mixture was shaken at 37°C for 40 minutes at 125 cycles/minute. After being centrifuged for 30 minutes, 200 µ 1 of its supernatant was collected into a mini-vial, while the rest was removed by an aspirator. The gland pellet was completely dried as the tube with its lid being opened. was kept for one night in a drying oven at 80°C and then the lid was closed and the weight was determined at room temperature. Then 100 µ of IN KOH was added thereto and the tube with its lid being closed was treated at 60°C for 1 to 2 hours so as to dissolve the pellet Then, the contents thereof were transferred to a mini- vial. Into the mini-vial containing the supernatant or gland pellet, 4 ml of Atomlite™ was added and then the radioactivity was measured by a liquid scintillation counter. Here, after the radioactivity of the gland pellet was corrected by using a sample in which 20 mM of NaSCN was added so as to cancel the hydrogen ion concentration gradient, the integration ratio of aminopyrine specifically trapped by the gland pellet was calculated. This experiment was performed in duplicate. ii-c) Calculation of the accumulation rate of aminopyrine Here, its principle will be briefly explained. In the isolated gastric fundic gland, acid is accumulated in a space between its secretory tubule and intraglandular cavity. Aminopyrine is weak base (pKa=5.0) and nonionic in a neutral solution so as to freely pass through the cell membrane, whereas it is ionized in an acidic solution and thus cannot pass through the cell membrane due to its electric charge. Therefore, aminopyrine is accumulated in a closed acidic space within the isolated gastric fundic gland. In view of this characteristic, the accumulation rate (R) of aminopyrine is calculated by the following equation: R = ((corrected radioactivity of precipitate)/ (radioactivity of supernatant)) X (200/(mg dry weight of gland pellet)) iii)Judgment Standard The effect of the sample compound at the final concentration of 10 -5 M was expressed by acid secretion inhibitory rate (%) as follows: acid secretion inhibitory rate (%) = (1-(R in sample group/R in control group)) x 100 AHP: Antibacterial Activity Test Against Helicobacter pyroli i)Meaning The minimum inhibitory concentration (MIC) against Helicobacter pyroli (microaerophilic gram-negative bacterium which is supposed to deeply involve in pathogenesis, relapse, and recrudescence of ulcer, referred to as " HP " in the following) is measured so as to find out compounds which have antimicrobial activity against Helicobacter pyroli . ii)Method MICs were determined by the agar dilution method. The stock culture (-80°C) of HP NCTC 11637 was thawed and cultured on tripticase soy agar supplemented with 5% sheep blood at 37°C in an atmosphere of 5% O 2 , 10% CO 2 , and 85%N 2 . Grown colonies were transferred to the same plate and precultured for 3 days under the same condition. An appropriate amount of the colony grown on the plate by preculturing was suspended in Mueller Hinton broth till turbidness was recognizable by naked eyes, and diluted 100- fold in the same broth; this resulted in a bacterial suspension for inoculation containing about 10 5 cfu/ml of the bacteria. A 1,000 µ g/ml solution of the sample compound containing DMSO not more than 25% was serieslly diluted 2- fold in sterile purified water. 100 µ l volume from each dilution was mixed thoroughly with 900 µ l of brucella agar supplemented with 5% horse blood and solidified in a 24 well micro plate, thereby yielding an MIC measurement plate. 10 µ l of the bacterial suspension for inoculation (about 10 3 cfu) was inoculated on this plate and cultured for 7 days under the same condition as that of preculture. Thereafter, it was judged whether there had been bacteria growth or not. iii)Judgment Standard The minimum concentration of the sample compound when there were no visible colonies or, if any, 5 or less colonies of HP was defined as MIC ( µ g/ml). PD: Gastric Mucosal Integrity Test i)Meaning There is a possibility that the anti-ulcer mechanism of the compounds which were effective in the experimental ulcer model may be attributed to adaptive cytoprotection, which means exhibiting of apparent anti-ulcer effect due to increase in the amount of endogeneous prostaglandins in the gastric mucosa caused by necrotizing agents. In this case, since the sample compound has a necrotizing effect, it is inappropriate as an anti- ulcer medicament. Therefore, the gastric mucosal potential difference (PD), which reflects the integrity of the gastric mucosa, is measured so as to confirm that the sample compound has no damaging effect on gastric mucosa, which is toxicity at gastric mucosal level. ii)Method Male Crj:SD rats (7 to 8-week-old) were fasted overnight, but allowed free access to water, and then, under urethane anesthesia (1.25 g/kg, i.p.), fixed to a cork board on its back. The abdomen of each rat was incised, and a small incision was made in the forestomach. Then, the inside of the stomach was washed with physiological saline heated at 37°C. From the forestomach, along the greater curvature thereof, the stomach was incised without damaging blood vessels. After the height of the cork board was adjusted on a jack, the stomach was mounted on ex vivo chamber. The area of the gastric mucosa exposed to the inside of this chamber was 2.5 cm 2 . The inside of the chamber was perfused with physiological saline warmed at 37°C by micro tube pump. By using an agar bridge containing 3M KCl, the potential difference between the chamber and the abdominal cavity was measured by a PD meter. Here, the rectal temperature was measured to control the body temperature during the experiment After the PD was sufficiently stabilized, the perfusate was stopped and then 100 mg/10 ml/kg of the sample compound dissolved or suspended in an aqueous solution of 0.5% sodium carboxymethyl cellulose or 0.05% Tween 80 was administered into the chamber, while PD was recorded for 60 minutes. To a control, the vehicle was administered. iii)Judgment Standard The change in PD during 60 minutes after the administration of 100 mg/kg of the sample compound was collectively studied and, with reference to the positive control, classified into 5 levels as follows: 5: Same as the control with no recognizable damage at all. 4: Though a slight PD-decreasing tendency suggesting a slight possibility of mucosal damage is found, there is no problem. 3: Though a weak decrease in PD and a possibility of a weak mucosal damage is recognized, there is no substantial problem. 2: Medium degree of decrease in PD is found and a mucosal damage is recognized. 1: Heavy degree of decrease in PD is found and a remarkable mucosal damage is recognized. AT: Single Dose Toxicity Pretest i)Method Male Slc:ICR mice (5-week-old) were used. Each group has 3 to 5 mice and each mouse was fasted, but allowed free access to water, for 4 to 5 hours from 9 a.m. in the test day. Then, 2,000 mg/10 ml/kg of the sample compound dissolved or suspended in an aqueous solution of 0.5% sodium carboxymethyl cellulose was orally administered thereto. To a control, only the vehicle was administered. The behavior and symptom were observed at each of 15 minutes, 30 minutes, 1 hour, 2 hours, and 3 hours after the administration and then daily till one week thereafter. The body weight was measured before and after the fasting as well as at the same time everyday. The dead animals were immediately subjected to autopsy and their organs were observed microscopically. Also, the living animals were sacrificed with ether or carbon dioxide one week after the administration and then their organs were observed microscopically. ii)Judgment Standard The toxicity at the single dose of 2,000 mg/kg of the sample compound was expressed as being classified into 5 levels. 5: Mortality rate is 0%; no toxicity is found at all both in behavior and organs. 4: Mortality rate is 0%; while no toxicity is found in organs, slight toxicity is observed in behavior and body weight increase. 3: While there is a dead animal (though not all the animals are dead), no toxicity is found in organs. 2: Regardless of whether there is a dead animal or not, toxicity is found in organs. 1: All the animals are dead. MTT: Cell Damaging and Protecting Effect Test i)Meaning It is confirmed that there is no toxicity in cell level. Those having a toxicity in cell level are inappropriate as an anti-ulcer drug. Also, it can be confirmed that the effects of the sample compounds in other cell level tests do not result from their toxicity. ii)Method A male Japanese White rabbit (2.5 to 3 kg) was anesthetized to death by Nembutal™ and, immediately thereafter, its stomach was removed. The greater curvature of the stomach was incised so as to remove the stomach contents therefrom. After the mucosal surface was washed with HBSS (Hanks' Balanced Salt Solution), the stomach in ice- cooled HBSS was transferred to a laboratory. Then, after the pyloric antrum was removed, the gastric corpus mucosa was separated by a spatula and then minced into 2 to 3 mm 3 pieces in BME (Basal Medium Eagle). Thereafter, these pieces were shaken at 120 to 130 cycles/minute for 15 minutes at 37°C in BME 60ml containing 280 U/ml of dispase and 30 to 50 U/ml of collagenase. Here, the concentration of collagenase was appropriately changed for each lot in view of the state of cells. The pieces were washed twice with EBSS (Earle's Balanced Salt Solution) containing 1 mM of EDTA and then shaken in MEM (Minimum Essential Medium) containing 1 mM of EDTA at 37°C for 5 minutes. Subsequently, they were shaken in the dispase and collagenase having the same concentrations as those mentioned above for 15 minutes so as to remove the supernatant and then further shaken at 37°C for 50 to 60 minutes at 120 to 130 cycles/minute. Then, after being washed twice with HBSS, Ham F12 containing 2% of Ultrocer G™ was used to attain the concentration of 1 x 10 6 cells/ml. Thus formed suspension was dispensed in each well of a 96-well plate by 200 µ l. The plate was incubated in the atmosphere composed of 5% CO and 95% air at 37°C for three days so as to attain a confluent state and then subjected to MTT assay. The sample compound was dissolved in DMSO so as to attain a concentration of 10 -2 M and then diluted with HBSS containing 2% of Ultrocer G™ so as to attain a final concentration of 10 -4 M. To each group, which 8 wells were used for, 10 µ l of MTT reagent was added immediately after 100 µ l of the medium in each well was exchanged for same volume of the resulting solution of the sample compound. After being incubated in an atmosphere composed of 5% CO 2 and 95% air at 37°C for 4 hours, thus formed solution was centrifuged and then its supernatant was discarded. Subsequently, 100 µ l of 100% ethanol was added to the residue so as to dissolve MTT formazan. Then, the absorbance (OD: 570 to 630) was measured by a microplate reader. This method utilizes a phenomenon in which MTT is changed to MTT formazan only by mitochondria of living cells so as to change color. iii)Judgment Standard The cell damaging or cell protecting effect of the sample compound at the final concentration of 10 -4 M was expressed as cell damaging rate (%) as follows: cell damaging rate (%) = (1- (absorbance in sample group/absorbance in control group)) × 100 Accordingly, the smaller value is better in the cell damaging rate.
