(a) Industrial Application Field The present invention relates to a novel isoindolinone derivative, and particularly to an isoindolinone derivative that has anti-inflammatory and antithrombotic effects and is useful as a pharmaceutical. (b) Conventional technology Conventionally, as isoindolinone derivatives, 2-
[4-(1-oxo-2-isoindolinyl)phenyl]propionic acid derivatives (Japanese Patent Publication No. 11627/1983, Japanese Patent Publication No. 29492/1983, 50156/1983)
JP-A-53-12852, etc.) and isoindolinyl phenylcarbonylpropionic acid derivatives (JP-A-53-12852, etc.) are known. However, there is no description of salicylic acid derivatives having isoindolinone as the core, nor is there anything that suggests this. (c) Problems to be Solved by the Invention The purpose of the present invention is to synthesize salicylic acid derivatives using isoindolinone as a core. Another object of the present invention is to develop isoindolinone derivatives having excellent pharmacological effects such as anti-inflammatory, antithrombotic, analgesic, and antipyretic effects. (d) Means for solving the problem The present invention is based on the general formula () shown below. (In the formula, R 1 is a hydrogen atom or a lower alkyl group,
The present invention relates to a novel isoindolinone derivative represented by R 2 (representing a hydrogen atom, a lower alkyl group, or an acyl group). In the general formula (), R 1 is a hydrogen atom or a lower alkyl group such as methyl, ethyl, n-propyl, isopropyl, n-butyl, isobutyl, etc., and R 2 is a hydrogen atom or a methyl, ethyl, n-propyl, isopropyl group. , n-butyl, isobutyl, n-pentyl, isopentyl, n-hexyl, lower alkyl groups such as isohexyl, or acetyl, benzoyl, substituted benzoyl (e.g., halogen atom, lower alkyl group, lower alkoxy group, nitro group, trifluoro 1 to 3 with methyl group, etc.
It means an acyl group such as a substituted benzoyl group) or a nicotinoyl group. In addition, -COOR 1 and - described in general formula ()
The substitution position of OR 2 is not particularly limited and may be substituted arbitrarily. Next, the method for producing the isoindolinone derivative of the present invention will be described. Manufacturing method (In the formula, R 1 is a hydrogen atom or a lower alkyl group,
R 2 and R have the same meanings as above) To explain the method in more detail, the O-phthalaldehyde acid or ester represented by the general formula () and the aromatic amine derivative of the general formula () are mixed in an organic solvent ( For example, when reacted at room temperature or under heating in benzene, toluene, xylene, dioxane, chloroform, methylene chloride, tetrahydrofuran, dimethylformamide, dimethyl sulfoxide, methanol, ethanol, propanol, etc., the benzylidene derivative represented by the general formula () is produced. can get. Next, the isolated benzylidene derivative of general formula () is suspended in alcohol and cooled on ice. Therein, sodium borohydride or potassium borohydride, which is a reducing agent, is added to the general formula () by 1 to 3
Add twice the mole. After the addition is complete, return to room temperature,
By reacting for about 0.5 to 10 hours, the target compound represented by the general formula () can be obtained in good yield. In addition, when O-phthalaldehyde acid or ester of general formula () is reacted with aromatic amine derivative of general formula () in an alcohol solvent (e.g., methanol, ethanol, propanol, etc.) at room temperature or under heating, a general reaction can be obtained. A benzylidene derivative represented by the formula () is immediately produced. Next, without isolating and purifying the benzylidene derivative, while cooling the reaction mixture solution on an ice bath, 1 to 3 times the mole of sodium borohydride or potassium borohydride as a reducing agent is added. After the addition is complete, the mixture is returned to room temperature and allowed to react for about 0.5 to 10 hours, thereby making it possible to obtain the target compound represented by the general formula () in an economical manner and in good yield. In addition, these manufacturing methods are only examples, and it can also be manufactured by other known methods. In addition, in the compound of the present invention, -COOH group or -
The compound having an OH group can be made into an inorganic salt or an organic salt, if necessary. In other words, these include pharmacologically acceptable salts, such as metal salts such as sodium and potassium, alkaline earth metal salts such as calcium, and salts with inorganic bases such as aluminum salts. , or organic bases such as ammonium salts, trimethylamine, triethylamine, arginine, and lysine. The compounds of the present invention can also be formulated with various pharmaceutical inert carriers to form tablets, capsules, ointments,
It can be made into various pharmaceutical preparation forms such as creams, gels, lotions, suppositories, sprays, syrups, and injections. (e) Effect The isoindoline derivative of the present invention was shown to have anti-inflammatory and antithrombotic effects in animal experiments using rats and mice, and was also shown to have analgesic and antipyretic effects. (f) Examples The present invention will be explained in more detail by way of Examples below, but of course the present invention is not limited only to these Examples. Example 1 1.5 g of O-phthalaldehydic acid and 1.5 g of 4-aminosalicylic acid were added to 30 ml of methanol, and the mixture was stirred at room temperature for about 30 minutes to precipitate crystals. While cooling the reaction solution on an ice bath and stirring, 0.5 g of sodium borohydride, which is a reducing agent, is gradually added. After the addition was completed, the temperature was returned to room temperature and the mixture was stirred for about 3 hours. The precipitated crystals were collected by filtration, dried, and recrystallized from dimethylformamide to produce N-4-(isoindolyl-
2.4 g of 2-one)-salicylic acid were obtained. Structural formula Melting point 278-280℃ (decomposed) Infrared absorption spectrum νc=o 1680cm -1 Mass spectrum M + 269 Example 2 1.5g of O-phthalaldehydic acid and 1.5g of 4-aminosalicylic acid were added to 30ml of methanol, and the mixture was heated to 30% at room temperature. If the mixture is stirred for more than a minute, a white crystalline benzylidene compound is produced. Next, 2.7 g of the obtained benzylidene compound is suspended in 30 ml of ethanol, and 0.6 g of potassium borohydride is gradually added while stirring and cooling in an ice bath. After the addition is complete, return to room temperature 5
After stirring for more than an hour, the precipitated crystals were collected by filtration, dried, and recrystallized from dimethylformamide to obtain 2.4 g of the compound shown in Example 1 as colorless prism crystals. Melting point 278-280°C (decomposed) Infrared absorption spectrum νc=o 1680cm 1 mass spectrum M + 269 Examples 3-6 The compounds shown in the following table were synthesized by the methods of Examples 1-2.
