Definitions
- the present invention relates to a novel methotrexate derivative, and more particularly, to a novel methotrexate derivative useful as an anti-rheumatic drug.
- Methotrexate has long been used as a treatment for leukemia, but in 1951 Gubner et al. Used aminopterin for rheumatoid arthritis (RA) and psoriasis. After reporting its efficacy, it has been noted as a therapeutic agent for RA and has been used mainly in Europe and the United States. More recently, a detailed study of dosage and administration has revealed that low-dose methotrexate therapy has relatively few side effects and excellent efficacy. Have been. However, since side effects such as liver damage and pulmonary fibrosis caused by taking methotrexet cannot be ignored, there is a demand for a drug with less side effects and excellent efficacy.
- the inventor of the present invention has conducted intensive research for a methotrexate derivative of this kind that has a better balance of efficacy and side effects as an antirheumatic agent, and has accomplished the present invention.
- the present invention provides the following general formula (I)
- R i and R z may be the same or different and represent a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms.
- the present invention also provides an anti-rheumatic drug having at least one of these compounds as an active ingredient.
- Figure 1 shows the cell proliferation rate at each concentration of the test drug
- the compounds of the present invention are known from W092 / 93436 as the general formula of the general concept. This is a novel compound that has not been described in the literature and is synthesized, for example, as follows.
- R and R may be the same or different and each represent a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms, A represents a protecting group, and X represents a halogen atom.
- the reaction for obtaining the compound of the general formula (3) from the compound of the general formula (1) and the compound of the general formula (2) is carried out by a commonly used amide bond formation reaction.
- the solution dissolved in a solvent such as rometan is added to an aqueous solution of the compound of the general formula (2) under ice-cooling or water-cooling, and potassium carbonate, sodium hydroxide, and sodium hydrogen carbonate are added.
- the reaction is carried out by stirring at room temperature in the presence of an inorganic salt such as water.
- examples of the protecting group represented by A include an amino group-protecting group such as an acyl group, and preferably include a carbobenzyloxy group, a tosyl group, and an acetyl group.
- the compound of the general formula (1) can be obtained, for example, by the method described in International Publication WO92 / 93436.
- the compound of the general formula (3) is deprotected by a usual method and converted into a compound of the general formula ().
- a compound of the general formula (3) is added to a solution of anisol-phenol or the like in a hydrogen bromide-acetic acid solution.
- the reaction is preferably carried out by stirring at room temperature for 10 to 60 hours.
- the protecting group is a carbobenzoxyl group
- the compound of the general formula (3) is dissolved in a solvent such as methanol, ethanol or acetic acid, and after adding palladium monocarbon, the mixture is placed under a hydrogen atmosphere. room temperature ⁇
- the compound of the general formula (4) and the compound of the general formula (5) are converted to a dimethyl acetate compound.
- a solvent such as dimethylformamide
- the reaction is carried out by stirring at 0 to 100 ° C, preferably at 50 ° C to 70 ° C.
- R z is a hydrogen atom
- an aqueous solution of an alkali such as a 1N aqueous solution of sodium hydroxide is added to a solvent such as methanol or ethanol, and the temperature is reduced from 0 ° C to 60%.
- the desired product is obtained by stirring at 15'C to 35 ° C.
- examples of the halogen atom represented by X include a bromine atom and a chlorine atom.
- the compound of the present invention can also be synthesized by the following method.
- R 1, R 2 , and R 3 may be the same or different and represent a hydrogen atom or a lower alkyl group having 1 to 4 carbon atoms, and X represents a halogen atom.
- the reaction for obtaining the compound of the formula (8) is carried out by reacting the compound of the general formula (4) with the compound of the general formula
- the reaction is performed in the same manner as in the reaction for obtaining the compound of the general formula (6) from the compound of the (5).
- the compound represented by the general formula (7) can be obtained, for example, by the method described in International Publication WO92 / 93436.
- the reaction for obtaining the compound (6) is carried out by a commonly used amide bond formation reaction.

- Organic salts such as tansulfonate, benzenesulfonate, p-toluenesulfonate, and metal salts such as sodium, potassium, and magnesium salts;
- it is an inorganic or organic acid salt, more preferably a hydrobromide or a methansulfonate.
- the drug containing the compound of the present invention can be administered orally or parenterally, but oral administration, local administration into the joint cavity and the like are preferable.
- the dosage varies depending on the patient's weight, symptoms, etc., but is usually preferably from 0.01 to 100 mg / day Z persons.
- Examples of the dosage form of the drug containing the compound of the present invention include liquid preparations such as injections, tablets, capsules, and powders.
- the compound of the present invention represented by the general formula (I) has an excellent anti-rheumatic action and toxicity balance as compared with methotrexate and existing methotrexate derivatives, so ⁇ Useful as a gusset.
- Example 1 Dissolve the compound of Example 1 (5.8 g) in ethanol (300), add 1N sodium hydroxide aqueous solution (32.2) at room temperature and add room temperature to room temperature. Then, the reaction solution was evaporated to dryness under reduced pressure, and the obtained solid was dissolved in water (100), and 1N hydrochloric acid was used.
- Example 2 The compound (100 mg) obtained in Example 2 was suspended in 2.4% hydrobromic acid (10), and dissolved by heating to 60'C in a hot water bath. Next, the mixture was filtered with a cotton plug, and the filtrate was cooled to room temperature and left overnight.
