3,7-disubstituted 6-carbethoxypyrazolo [1,5-a] pyrimidines and 3,7-disubstituted 6-ethoxypyrazolo-[1,5-a]pyrimidines have been prepared and evaluated as adenosine cyclic 3',5'-phosphate (cAMP) phosphodiesterase (PDE) inhibitors vs. the low Km enzyme isolated from beef heart, rabbit lung, and kidney preparations. The results were found to be between 0.5 to 13 times as potent as theophylline as inhibitors

While 3(5)-aminopyrazole reacts with enaminonitrile to yield pyrazolo[1,5-a]pyrimidines, 3-amino-5-pyrazolone reacts with the same reagents to yields pyrazolo[3,4-b]pyridines.
3(5)-氨基吡唑与烯腈反应生成吡唑并[1,5- a ]嘧啶,而3-氨基-5-吡唑酮与相同的试剂反应生成吡唑并[3,4- b ]吡啶。
