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)].
提供选择性抑制 PDE 7 并因此提高细胞 cAMP 水平的噻吩并吡唑衍生物。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。该化合物是由下式(I)代表的噻吩并唑化合物:
[其中,R1 特别是环己基、环庚基或四氢吡喃基;R2 是甲基;R3 是氢原子;R4 是基团:-CONR5R6(其中 R5 和 R6 中的任一个是氢原子)]。
