To provide thienopyrazole derivatives inhibiting PDE 7 selectively, and therefore, enhance cellular cAMP level. Consequently, the compound is useful for treating various kinds of disease such as allergic diseases, inflammatory diseases or immunologic diseases. The compound is thienopyrazole compound represented by the following formula (I):
[wherein, especially, R1 is a cyclohexyl, a cycloheptyl group or a tetrahydropyranyl group; R2 is methyl; R3 is a hydrogen atom; and R4 is a group: —CONR5R6 (in which any one of R5 and R6 is a hydrogen atom)].
为了提供选择性抑制PDE 7的噻吩嘧啶衍生物,从而增强细胞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(I)表示的噻吩嘧啶化合物:[其中,特别地,R1是环己基,环庚基或四氢吡喃基; R2是甲基; R3是氢原子; R4是一个基团:-CONR5R6(其中R5和R6中的任何一个是氢原子)]。
