4-Aminopyrazolo[3,4-d]pyrimidine Structural

What is 4-Aminopyrazolo[3,4-d]pyrimidine?

Description

4-aminopyrazolo[3,4-d]pyrimidine (4-APP), the isomer of adenine with the five-membered ring in the pyrazole configuration, is by far the most potent inhibitor of both enzymatic reactions catalyzed by Stx1. It is also a new type of mTOR inhibitor. The 4-aminopyrazolo[3,4-d]pyrimidines, a well-characterized class of compounds for tyrosine kinase inhibition, were used as a Src inhibitor module that blocks the adenosine binding site[1-2].
