  日期：1996.1.1

  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
