Abstract

PURPOSE:To provide an antiulcer agent containing 1-substituted-3-(2-norbornyl) urea as an active component, having anticholine activity and autonomic nerve suppressing action, free from the central nerve suppressing action as side effect, and useful especially to peptic ulcer caused by stress. CONSTITUTION:The compound of formula (X is O or S; R1 is H or 1-6C alkyl; R2 is 1-6C alkyl or phenyl; when R2 is phenyl, R1 is H) is used as an active component of the objective antiulcer agent. It has been found that the compound of formula is effective to various ulcers as an antiulcer agent, especially as a remedy for peptic ulcer caused by stress. Furthermore, the compound of formula has anticoline activity and autonomic nerve supressing action, and excellent effect to improve the microcirculation. It has little side effect to suppress the central nervous system. The antiulcer agent is administered orally or by intravenous injection. Dose: preferably 1-200mg/kg by oral administration and 0.5-10mg/kg by intravenous injection.

After administering the test compound to a Wistar-SPF (male) (200g), the animal is placed in a stress gauge and immersed in a water tank (22-25°C) in an upright position up to the xiphoid process of the sternum. 20
After an hour, remove the stomach, inject 1 cup of formalin, and immerse the entire stomach in 1% formalin. After 10 minutes, an incision is made along the large curved side, and the length of the hemorrhagic sore that has occurred on the mucosa (line stomach area) is measured using a stereomicroscope, and the sum of the lengths is taken as the ulcer index for each animal. The test compound is suspended in a 0.5z carboxymethyl cellulose solution and administered orally at a rate of 30 mg. The antiulcer effect thus obtained was calculated using the following formula and is shown in Table 1 as the average value for 4 to 5 animals per group.
