Description

TECHNICAL FIELD
The present invention, which relates to a novel acetamide derivative having both of an inhibition of gastric acid secretion and a potentiation of defensive factor, is a useful invention in the medicinal field.
BACKGROUND ART
Peptic ulcer occurs owing to ill-balance between offensive factors such as gastric acid and pepsin, and defensive factors such as gastric mucus and mucosal blood flow. In particular, gastric acid is considered to take part in it importantly. Therefore, there are now widely used offensive factor inhibitors, for example, histamine H.sub.2 -receptor blockers having particularly potent inhibition of gastric acid secretion, such as cimetidine and famotidine. However, there is a problem in the use of histamine H.sub.2 -receptor blockers such as recrudescence or relapse of the ulcer after breaking the use thereof. It is considered that such problem occurs mainly due to defensive factors such as gastric mucosa, which are weakened by the potent inhibition of gastric acid secretion. So, there has been desired the development of a medicament having both of an inhibition of gastric acid secretion and a potentiation of defensive factor. As such medicaments, there are described, for example, compounds having pyridine ring in Japanese Unexamined Patent Publication No. 225371/1988, U.S. Pat. Nos. 4,912,101 and 4,977,267. However, there has not yet been known any compound which satisfactorily possesses both of the above-mentioned inhibition of gastric acid secretion and potentiation of defensive factor.
The object of the present invention is to provide a novel compound effective for preventing and treating peptic ulcer and gastritis, which not only has both of potent inhibition of gastric acid secretion and potentiation of defensive factor, but also has an accelerating effect for curing chronic ulcer.

(a) N-�4-�3-(piperidinomethyl)phenoxy!-cis-2-butenyl!-2-�2-(ethoxycarbonylamino)ethylsulfinyl!acetamide ##STR141##
There was dissolved 1.64 g (0.0074 mol) of 2-�2-(ethoxycarbonylamino)ethylsulfinyl!acetic acid in 80 ml of 50% dimethylformamide-dichloromethane and added 1.13 g (0.0074 mol) of HOBt and 1.52 g (0.0074 mol) of DCC under cooling with ice, and the mixture was stirred for 30 minutes under cooling with ice. Thereto was added 1.91 g (0.0074 mol) of 4-�3-(piperidinomethyl)-phenoxy!-cis-2-butenylamine and the mixture was stirred for 18 hours at room temperature. The obtained precipitate was filtrated off, and the filtrate was washed with 5% aqueous solution of sodium hydroxide and with water successively, and dried over anhydrous sodium sulfate. The solvent was removed under reduced pressure, and the residue was purified by silica gel column chromatography (chloroform:methanol=10:1). Then the obtained crystals were recrystallized from ethyl acetate-n-hexane (1:1) to give 1.3 g of the titled compound.

(b) N-�4-�3-(piperidinomethyl)-phenoxy!-cis-2-butenyl!-2-�2-(ethoxycarbonylamino)ethylsulfinyl!acetamide hibenzoate ##STR142##
There were dissolved 9 g (0.0 19 3 mol) of the acetamide obtained in the above step (a) and 4.68 g (0.0193 mol) of hibenzoic acid in 30 ml of ethanol and the mixture was stirred for 3 hours at room temperature. Thereto was added 120 ml of ethyl acetate, and when the deposit of crystals starts, the mixture was allowed to stand under cooling with ice. The deposited crystals were filtrated and dried, and then dissolved in 65 ml of ethanol. To the solution was added 360 ml of ethyl acetate and the solution was allowed to stand at room temperature. When the deposit of crystals starts, the solution was allowed to stand further overnight in the refrigerator. The obtained crystals were filtrated to give 10 g of the hibenzoate as white crystals.

(c) N-�4-�3-(piperidinomethyl)phenoxy!-cis-2-butenyl!-2-�2-(ethoxycarbonylamino)ethylsulfinyl!acetamide fendizoate ##STR143##
There were dissolved, at 50.degree. C., 8.0 g (0.017 mol) of the acetamide obtained in the above step (a) and 5.47 g (0.017 mol) of fendizoic acid in 13 ml of ethanol and added 130 ml of acetone and the mixture was allowed to cool.

Test Example
With respect to anti-ulcer effect of the compounds having the general formula (I), there were carried out a test of ulcer induced by pylorus-ligation, which ulcer is induced mainly due to offensive factors; a test of ulcer induced by hydrochloric acid/ethanol, which ulcer is induced mainly due to defensive factors such as mucosal blood flow and mucus; and a test of ulcer induced by a stress of restraint plus water-immersion, which ulcer is induced due to both of offensive and defensive factors. Further, there were carried out a test of ulcer induced by acetic acid as a chronic ulcer model and a test of cure-prolonged ulcer induced by acetic acid. Also, there was examined an activity of increasing gastric mucosal blood flow, which activity brings about acceleration of regeneration of the gastric mucosa. As test compounds, hydrochloride salts were used.
The test methods and results thereof are shown in the followings.
�Test of ulcer induced by pylorus-ligation!
The pylorus of a wistar male rat weighing 230 to 250 g, which had fasted for 48 hours, was ligated under ether-anesthesia, according to a usual method. After 14 hours, the animal was sacrificed by ether and the stomach was taken out therefrom.
The area of the ulcer generated on the fore-stomach was measured and the total area of the ulcer per rat was classified into the following six grades to give ulcer coefficients (Table 4).
