The present invention is based on the general formula () A novel 2,3-dihydro-
This invention relates to indene derivatives. To explain R 1 in the above general formula () more specifically, the halogen atom is fluorine, chlorine,
Represents bromine and iodine. The compound of the present invention is a new compound that has not been described in any literature, and has useful pharmacological effects such as remarkable anti-inflammatory effect, analgesic effect, antipyretic effect, anti-allergic effect, platelet aggregation inhibiting effect, and anti-hypercholesterol effect. It is a compound useful as So far, only sodium cromoglycate has been known as an antiallergic agent, particularly as an atopic antiallergic agent. However, sodium cromoglycate has the disadvantage that sufficient pharmacological effects cannot be expected when administered orally.
It is desired to develop an atopic antiallergic agent that can be administered orally. Therefore, the present inventors searched for a new compound that can be orally administered and has an atopic antiallergic effect, and searched for a new compound that can be administered orally and has a 2,3-
When dihydro-indene derivatives were synthesized and various pharmacological effects were investigated, they were found to have remarkable anti-inflammatory, analgesic, antipyretic, and antiallergic effects when administered orally. Furthermore, the present invention was completed based on the discovery that the compound of the present invention has pharmacological effects such as platelet aggregation inhibiting effect and anti-hypercholesterolemic effect, and is an industrially useful compound as a pharmaceutical. The compounds of the present invention can be obtained in good yields by the methods described below, but these production methods are merely examples, and of course they can also be produced by other chemically similar methods. Manufacturing method A However, in the formula, R 1 has the same meaning as above, R 3 represents a hydrogen atom, a lower alkoxy group, or a lower alkoxycarbonyl group, X represents a halogen atom, and Y represents a cyano group or a lower alkoxycarbonyl group. Manufacturing method B However, in the formula, R 1 and Y have the same meanings as above,
R 2 represents a pyrrolidino group, a piperidino group, or a morpholino group. These manufacturing methods will be explained in more detail. Production method A involves combining compound () and an alkylating agent in the presence of an alkali (e.g., sodium methylate, sodium ethylate, potassium t-butyrate, sodium amide, sodium hydride, etc.) in a solvent (e.g., methanol, ethanol, tetrahydrofuran, benzene, toluene, xylene, dioxane, dimethylformamide, dimethyl sulfoxide, hexamethylene phosphotriamide, etc.) for 3 to 48 hours at room temperature or heating as necessary, and then hydrated using a mineral acid (e.g. hydrochloric acid, sulfuric acid, etc.). Obtained by decomposition. Incidentally, during the hydrolysis reaction, an organic solvent such as acetic acid may be used to maintain uniformity of the reaction. Production method B involves the reaction of compound () with acrylonitrile or acrylic acid lower alkyl ester in an organic solvent (e.g. methanol, ethanol, tetrahydrofuran, dioxane, benzene, dimethylformamide, etc.), passing nitrogen if necessary.
After heating at 30 to 120° C. for 48 hours, it may be hydrolyzed with a mineral acid (eg, hydrochloric acid, sulfuric acid) in an organic solvent such as acetic acid, or with diluted hydrochloric acid, diluted sulfuric acid, etc. in the absence of a solvent. Next, examples of the present invention will be shown. Example 1 22 g of 3-pyrrolidino-5-chloro-indene and 18 g of acrylic acid methyl ester were added to 70 ml of dioxane.
and heated under reflux for 5 hours. After the reaction, the solvent was distilled off under reduced pressure, the residue was dissolved in 100 ml of acetic acid, and diluted with hydrochloric acid.
100 ml was added and heated under reflux for 3 hours. After the reaction is complete,
The solvent was distilled off under reduced pressure, and the resulting crude product was recrystallized from ethyl acetate by adding ice water to give 16 g of 6-chloro-1-oxo-2,3-dihydro-2-indenpropionic acid as colorless needles. I got it. The melting point of this substance was as follows. Melting point: 171-173°C Examples 2-3 According to the method of Example 1, the following compounds were obtained. Example 2 6-fluoro-1-oxo-2,3-dihydro-2-indenepropionic acid Melting point 109-110.5°C Colorless needles Example 3 6-nitro-1-oxo-2,3-dihydro-
2-indenepropionic acid Melting point: 125-127°C Colorless needle crystals Next, the results of pharmacological experiments on the compound of the present invention will be shown. Experimental Example 1 Effect on Passive Arthus Response in Rats Using the method of Denk et al [z.
Immun; Taetsforsch, 138, 169 (1969)]. That is, anti-BSA rabbit serum (precipitated antibody titer 32 times) was applied to rats that had been fasted for 18 hours.
Sensitization was carried out by injecting 0.3 ml of a 10% solution of the same into the tail vein.
0.025% bovine serum albumin (BSA) 30 minutes after sensitization
Induction was performed by subcutaneously injecting 0.1 ml of the solution into the right hind foot pad of each individual. Three hours after the induction, the paw volume was measured according to Fujihira's method [Applied Pharmacology 5, 169 (1971)], and the edema suppression rate was calculated according to the following formula. 7-chlor-1-oxo-1 of the test compound and comparator drug,
2,3,4-tetrahydro-2-naphthalenepropionic acid (hereinafter referred to as Comparative Compound 1) and indomethacin (hereinafter referred to as Comparative Compound 2) were both suspended in a 0.5% aqueous solution of gum tragacanth at 100 mg/Kg each.
and 5 mg/Kg was orally administered 1 hour before BSA induction. In addition, a solvent was administered to the control group. Edema rate (%) = Foot volume 3 hours after BSA induction - Foot volume before BSA induction / Foot volume before BSA induction x 100 Edema suppression rate (%) = Edema rate of control group - Edema rate of drug administration group / The edema rate of the control group x 100 The results are shown in the table below.
