摘要

This study reports the synthesis of a number of 1-and 2-alkyl derivatives of the 4- aminopyrazolo [3, 4-d] pyrimidine (APP) nucleus and their evaluation as inhibitors of ADA from bovine spleen. The 2-substituted aminopyrazolopyrimidines proved to be potent inhibitors, most of them exhibiting K i values in the nanomolar/subnanomolar range. In this series the inhibitory activity is enhanced with the increase in length of the alkyl chain, ...
