A series of 6-phenylpyrazolo[3,4-d]pyrimidones is described which are specific inhibitors of cGMP specific (type V) phosphodiesterase. Enzymatic and cellular activity as well as in vivo oral antihypertensive activity are evaluated. A n-propoxy group at the 2-position of the phenyl ring is necessary for activity. A series of products substituted at the 5-position in addition to the 2-n-propoxy was prepared
描述了一系列6-苯基吡唑并[3,4-d]嘧啶酮,它们是cGMP特异性(V型)磷酸二酯酶的特异性抑制剂。评价了酶和细胞活性以及体内口服降压活性。苯环的2位上的正丙氧基是活性所必需的。制备并评估了除2-正丙氧基外在5-位取代的一系列产物。这个职位可以容纳许多无关的团体。氨基衍生物非常有效,但缺乏代谢稳定性。碳连接的小杂环取代提供了高水平的活性和稳定性。细胞活性经常与体内活性相关。在这些化合物中,1,3-二甲基-6(2-丙氧基-5-甲磺酰胺基苯基)-1,5-二氢邻苯二酚[3,
