DETAILED DESCRIPTION OF THE INVENTION The present invention relates to novel amidine derivatives represented by the following general formula, acid addition salts thereof, and methods for producing them. The symbols in the formula have the following meanings. R: hydrogen atom or lower alkyl group m and n: each integer of 1 to 3 Y: oxygen atom or sulfur atom R 1 : hydroxyl group, lower alkoxy group or lower acyloxy group R 2 : hydrogen atom, lower alkyl group In addition, the above general To further explain the compound of formula:
The word “lower” in the explanation of general formulas refers to the number of carbon atoms from 1 to
It is a straight or branched carbon chain having 5 carbon atoms. Therefore, lower alkyl groups include methyl, ethyl, isopropyl, butyl, and the like, and lower alkoxy groups include methoxy, ethoxy, propoxy, and the like. Further, the lower acyloxy group means an acetoxy group, a propionyloxy group, an isobutyroyloxy group, etc. Since the compound of the above general formula [] forms an acid addition salt and has tautomers, it includes these salts and isomers. The compound [ ] provided by the present invention is characterized in that it has a gastric acid secretion suppressing action, and its action is not based on anticholinergic action. Furthermore, the compound []
Some of them suppress gastric acid secretion based on their antagonism of histamine H2 receptors. Most of conventional commercially available antacids are based on anticholinergic effects, and side effects due to anticholinergic effects have been pointed out, so the compound of the present invention has been proposed as a new type of gastric acid secretion inhibitor. It's promising. The object compound of the present invention can be obtained using the Shay rat 4hr method (Shsy rat 4hr method).
et al., Gastroenterology, Vol. 5, pp. 43-61, 1945.
(2007), it has been confirmed that doses of 10 to 50 mg/Kg or less effectively suppress gastric acid secretion. For the purpose of suppressing gastric acid secretion, the compound of interest of the present invention is suitably administered at 100 to 800 mg per day in 1 to 4 divided doses. Administration is carried out in the form of free base or pharmaceutically acceptable salts. Acceptable salts include, for example, hydrochlorides, hydrobromides, hydroiodides, sulfates, maleates, picrates, and the like. Administration can be carried out either orally or parenterally, and dosage forms suitable for such administration can be prepared by conventional methods. According to the present invention, the amidine derivative represented by the general formula [] is produced by the following method. (In the formula, R′ means a lower alkyl group. Also,
R, m, n, Y, R 1 and R 2 have the meanings given above. ) This method involves reacting the starting compound [ 1 ] with the amine represented by the compound [ 1 ] in a reaction-corresponding amount, or reacting the raw material compound [ 2 ] with the amine represented by the compound [ 2 ] in the reaction-corresponding amount. It is carried out by. Amine used here [
1 ] or [ 2 ] can react with the raw material compound to give the target compound [ ], and [ 1 ] includes, for example, ammonia, ammonium chloride,
Lower alkylamines such as methylamine, ethylamine, and isopropylamine; and [ 2 ] includes hydroxylamine, O-methylhydroxylamine, O-ethylhydroxylamine, O-ethylhydroxylamine, and
O-lower alkylhydroxylamines such as -butylhydroxylamine; O- such as O-acetylhydroxylamine, O-propionylhydroxylamine, O-butyroylhydroxylamine, etc.
These include lower acylhydroxylamines. This reaction is usually carried out in a solvent, and examples of suitable solvents include alcohol, isopropanol, chloroform, ether, tetrahydrofuran, and benzene. These solvents preferably do not contain water. There is no particular restriction on the reaction temperature, but it is appropriate to carry out the reaction at room temperature or under heating. Further, the liquid property of the reaction solution is preferably neutral to basic. In order to further explain the manufacturing method of the present invention,
Examples are listed below. Furthermore, among the symbols indicating the physical and chemical properties of the products in the examples, mp means the melting point and Anal. means the elemental analysis value, respectively. Example 1 Methyl 3-(2-guanidinothiazole-4-
Dissolve 4.72 g of (methylthio)propionimidate in 35 ml of methyl alcohol, and dissolve 1.2 g of hydroxylamine hydrochloride in 0.93 g of sodium methoxide.
After adding 25 ml of the methyl alcohol solution of the free hydroxylamine treated in step (g) and stirring at room temperature for 2 hours, the solvent was distilled off under reduced pressure, and the residue was purified by column chromatography using a chloroform-methyl alcohol mixed solvent as a developing solvent. Recrystallization from acetone yields 1.3 g of 3-[(2-guanidinothiazol-4-yl)methylthio]propionamide oxime. This material exhibits the following physical and chemical properties.
