The present invention relates to novel oxamide derivatives, processes for their preparation, and pharmaceutical compositions containing them. More specifically, the present invention provides oxamide derivatives which have an immunomodulatory effect and therefore have a therapeutic effect on immune diseases such as rheumatoid arthritis, and which are also useful for viral diseases or anti-cancer immunotherapy. The present invention relates to a manufacturing method and a pharmaceutical composition containing the same. Traditionally, for autoimmune diseases such as rheumatoid arthritis,
Numerous steroidal and non-steroidal anti-inflammatory drugs are also used clinically. However, many of these drugs are still not fully satisfactory in terms of their pharmacological effects, side effects, toxicity, etc. The present inventors have conducted extensive research into chemical substances that exert specific effects on cells involved in immune responses and have the ability to change the immune response of the host. and,
We have succeeded in obtaining a new oxamide compound that has low toxic effects and is highly desirable as a pharmaceutical. The novel compounds provided by the present invention have the general formula (In the formula, R 1 represents a hydrogen atom, a halogen atom, a lower alkyl group, a lower alkoxy group, a substituted or unsubstituted phenoxy group, a nitro group, or a cyano group, and R 2 represents a hydrogen atom, a lower alkyl group, or a lower alkylthio group. These compounds exhibit amine-type and imine-type tautomers. Therefore, the compounds of the present invention include all these tautomers. Representative examples of the compounds of the present invention are as follows. N,N'-bis(4-phenylthiazole-2
-yl)oxamide. N,N'-bis[4-(p-chlorophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(m-chlorophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(o-chlorophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(p-bromophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(m-bromophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(o-bromophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(p-methylphenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(m-methylphenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(o-methylphenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(p-methoxyphenyl)
Thiazol-2-yl]oxamide. N,N'-bis[4-(m-methoxyphenyl)
Thiazol-2-yl]oxamide. N,N'-bis[4-(o-methoxyphenyl)
Thiazol-2-yl]oxamide. N,N'-bis[4-(p-phenoxyphenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(p-(4-chlorophenoxy)phenyl)-5-methylthiazole-2-
] Oxamide. N,N'-bis[4-(p-nitrophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(m-nitrophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(o-nitrophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(p-cyanophenyl)thiazol-2-yl)oxamide. N,N'-bis[4-(m-cyanophenyl)thiazol-2-yl]oxamide. N,N'-bis[4-(o-cyanophenyl)thiazol-2-yl)oxamide. N,N'-bis(5-methylthio-4-phenylthiazol-2-yl)oxamide. The compound of the present invention represented by the general formula (1) can be obtained by the method of the present invention by the general formula (In the formula, R 1 and R 2 have the above definitions.) It can be produced by reacting the 2-aminothiazole represented by the following with oxalyl chloride. This reaction is carried out by dissolving or suspending the starting material represented by the general formula () in a solvent or suspending it in a solvent, and adding oxalyl chloride dropwise to this solution. This can be done by adding by the following methods. The amounts of reaction components used are usually stoichiometrically calculated amounts. That is, it is appropriate to use the aforementioned 2-aminothiazoles in twice the molar amount of oxalyl chloride. Suitable solvents used in this reaction include, for example, benzene, toluene, xylene, acetone, ethylmethylketone, dioxane, 1,2-dimethoxyethane, tetrahydrofuran, and N,N-dimethylformamide. In order to remove hydrogen chloride generated during the reaction, an organic base such as pyridine or triethylamine or an inorganic base such as sodium carbonate, potassium carbonate, or sodium bicarbonate may be used. Although this reaction usually proceeds at temperatures below room temperature, it is also possible to heat the solvent to a temperature up to the boiling point of the solvent in order to accelerate the reaction. Most of the 2-amino-4-phenylthiazoles which are the starting materials represented by the general formula () are known compounds, for example, in the literature [Jacques
V. Metzger, ed. âThe Chemistry of
Heterocyclic Compounds,âVol34: Thiazole
And Its Derivatives, Part two (1979)]. The compound represented by the general formula () of the present invention has pharmacological activity. What is noteworthy is that these compounds have excellent immunomodulatory effects, and the compounds of the present invention have low toxicity, making them extremely useful as medicines. The pharmacological activity of the compounds of the present invention was confirmed as follows. Many experimental systems are routinely used to test immunomodulatory effects using animals, but the results of the most representative test, the delayed-type hypersensitivity reaction enhancement test, are shown below. Delayed hypersensitivity induced in mice by applying picryl chloride (2-chloro-1,3,5-trinitrobenzene) to the skin is known as a typical cell-mediated immune phenomenon, and as an experimental system. It is one of the systems widely used worldwide (Asherson. GLand Ptak, W.: Contact and
delayed hypersensitivity in the mouse I.
Active sensitization and passive transfer.
Immunology, 15 , 405-416 (1968)). This experimental system was used in a delayed hypersensitivity enhancement test. Test Example 1 Delayed hypersensitivity reaction enhancement test Test method: ICR male mice weighing approximately 30 g were used in groups of 8 mice. Sensitization was performed by dissolving 3% picryl chloride in a 4:1 solution of olive oil and acetone and applying it to the shaved abdomen of the mouse. Simultaneously with sensitization, the compound of the present invention dissolved or suspended in 0.2% carboxymethylcellulose physiological saline was orally administered at a rate of 50 mg per kg of mouse body weight. For the control group, 0.2% carboxymethylcellulose physiological saline was administered in the same manner. To induce delayed-type hypersensitivity (challenge), 7 days after sensitization, a felt wrapped in forceps soaked in olive oil containing 1% picry chloride was applied to the ears of the mouse. I did it. The thickness of the mouse ears was measured before the challenge and 24 hours after the challenge, and the rate of increase in thickness (average value of both ears of 8 mice) is shown in Table 1. For comparison, the results of a similar test using levamisole hydrochloride are also shown. An F-t test was performed on the test results, and those with a significant risk rate P < 0.05 compared to the control group were marked with a ã.
Significant values at P<0.01 are marked with â. Results: When the compound of the present invention was administered simultaneously with sensitization, the delayed hypersensitivity response induced by challenge was enhanced. The compound of the present invention was found to have an activity equal to or greater than that of levamisole used for comparison. That is, the compound of the present invention is considered to have an effect of regulating cellular immune response in mice (immunomodulating ability).
