Thieno(2,3-d)pyrimidine compounds of general formula (1) useful as drugs having a cGMP-specific phosphodiesterase inhibiting effect and so on; and a process for the preparation of the same wherein Q is a group represented by the general formula: (CH2)n-N(r1)-C(r2) (r3), CH=CH-CH=CH, or (CH2)m which is bonded to a and b; R1 is hydrogen or C1-C6 alkyl; R2 is C3-C8 cycloalkyl optionally substituted with G1, phenyl optionally substituted with G2, or a saturated or unsaturated heterocyclic group having 1 to 4 heteroatoms selected from among N, O and S and being optionally substituted with G3; and R3 is a saturated or unsaturated heterocyclic group having 1 to 4 heteroatoms selected from among N, O and S and being optionally substituted with G3 or a group represented by the general formula: (CH2)kC(=O)R4 or CH=CHC(O)R4.
通式(1)的噻吩并(2,3-d)嘧啶化合物,可用作具有 cGMP 特异性磷酸二酯酶抑制作用的药物等;及其制备方法 其中 Q 是由通式表示的基团:(CH2)n-N(r1)-C(r2)(r3),CH=CH-CH=CH,或(CH2)m,与a和b键合;R1是氢或C1-C6烷基;R2是任选被G1取代的C3-C8环烷基,任选被G2取代的苯基,或具有1至4个选自N、O和S的杂原子并任选被G3取代的饱和或不饱和杂环基团;和 R3 是一个饱和或不饱和杂环基团,具有 1 至 4 个从 N、O 和 S 中选出的杂原子,并可选择被 G3 取代,或者是一个由通式表示的基团:(CH2)kC(=O)R4 或 CH=CHC(O)R4。
