The present invention relates to novel 5-substituted pyrazolo[4,3-d]pyrimidine-7-one compounds, and compositions, methods of use and processes to make therefor. The novel compounds are useful in the treatment of cardiovascular disorders, such as heart failure or cardiac insufficiency. The novel compounds bind adenosine receptors and selectively inhibit phosphodiesterase.

5-substituted pyrazolo[4,3-d]pyrimidines that were synthesized during the course of the analysis. With use of the correlation as a guide, one additional 5-phenylpyrazolo[4,3-d]pyrimidine containing a 4-[[(dimethylamino)ethyl]amino]sulfonyl substituent to improve aqueous solubility was prepared. On the basis of the high correlation between adenosinebinding affinities of analogously substituted xanthines and pyrazolo-[4
