The inosine or deoxyinosine and the higher fatty acid having an odd number of carbon atoms react with each other to form an ester in the same manner as in the usual reaction between a carboxylic acid and an alcohol. In the case of inosine, among the four hydroxyl groups, the hydroxyl group at the 6-position is not involved in esterification due to poor reactivity, and 2 ′
Three hydroxyl groups at the 3'-position, 3'-position and 5'-position participate in esterification. In the present invention, at least one of these three hydroxyl groups needs to be esterified, but the other hydroxyl groups may be left as they are or may be esterified. Therefore, for example, if inosine and one of the odd higher fatty acids are subjected to an esterification reaction, a total of seven inosine derivatives (esters) of the present invention are obtained.

In the case of deoxyinosine, of the three hydroxyl groups in total, the hydroxyl group at the 6-position is also poor in reactivity, so that the hydroxyl groups involved in esterification are two at the 3'-position and the 5'-position. . As with inosine, at least one of these two hydroxyl groups must be esterified, while the other hydroxyl groups may or may not be esterified. Therefore, for example, if deoxyinosine and one of the odd higher fatty acids are subjected to an esterification reaction, the resulting deoxyinosine derivative (ester) of the present invention is three in total.

On the day after the end of intraperitoneal administration of each test solution, the spleen of each group of mice was excised, and antibody-producing cells in spleen cells were detected according to the method of Gern et al. In this method, the antibody-producing ability is represented by the number of antibody-producing cells per spleen of one mouse. In addition, the antibody production inhibition rate is a value obtained by subtracting the antibody production ability of the antibody production inhibitor administered group of the example from the antibody production ability of the control group by the antibody production ability of the control group and multiplying by 100. expressed. In this evaluation,
In calculating the antibody production inhibition rate, the average value of 6 mice in each group was used for the antibody production ability of the control group and the administration group. Table 1 shows the results.
