Test example 2 Effect of isoindolinone derivative-containing composition on the histopathological characteristics of the tibetan Joint of arthritic mice
The effect of a mixture of compound 8 and compound 30 at a mass ratio of 10 (MIX (8-30) (R ═ 10)) and compound i on the histopathological characteristics of the tibialis joint of arthritic mice was examined using the method disclosed in McCann FE et al (Arthritis Res ther. 2010; 12(3): R107), and the results are shown in table 11.
TABLE 11 Effect of each drug on the histopathology of the tibiotarsal joints in arthritic mice
As can be seen from table 11, when MIX (8-30) (R ═ 10) was administered at a dose of only 1/10 for compound i, the tibioarticular histopathology scores of the former-treated mice were significantly lower in part than compound i, while no statistical difference was observed in part compared to compound i.
