The present invention provides the compounds inhibiting PDE 7 selectively, and therefore, enhances cellular cAMP level. Consequently, the compound is useful for treating various kinds of disease such as allergic disease, inflammatory disease or immunologic disease. The compound is imidazotriazinone compound represented by the following formula (IA) or (IB): especially, R1 is cyclohexyl group, R2 is methyl group; R3 is a hydrogen atom; nitro group; cyano group; a halogen atom; heteroaryl group; substituted or unsubstituted C1-C6 alkyl group; substituted or unsubstituted C2-C6 alkenyl group; saturated or unsaturated heterocycloalkyl group which is substituted or unsubstituted; a group: —NR5R6, —C(O)R7, —SO2R7, —OR8, —NR8COR7, —NR8S02R7; A is CR4; and B is CH.
本发明提供了选择性抑制PDE7的化合物,因此提高了细胞cAMP水平。因此,该化合物可用于治疗各种疾病,如过敏性疾病、炎症性疾病或免疫性疾病。该化合物是由以下式子(IA)或(IB)表示的咪唑三嗪酮化合物:特别地,R1是环己基基团,R2是甲基基团;R3是氢原子;硝基团;氰基团;卤素原子;杂环基团;取代或未取代的C1-C6烷基团;取代或未取代的C2-C6烯基团;取代或未取代的饱和或不饱和杂环烷基团;一种基团:—NR5R6,—C(O)R7,—SO2R7,—OR8,—NR8COR7,—NR8S02R7;A为CR4;B为CH。
