4-Aminopyrazolopyrimidine scaffold and its deformation in the design of tyrosine and serine/threonine kinase inhibitors in medicinal chemistry

Abstract

The 4-Aminopyrazolopyrimidine scaffold has been an interesting pharmacophore since the disclosure of the intimate connection between small-molecule inhibitors and the treatment of diseases. Modification of the 4-aminopyrazolopyrimidine scaffold according to different targets, especially tyrosine kinase and serine/threonine kinase, has resulted in a variety of small-molecule inhibitors. Kinase inhibitors with 4-aminopyrazolopyrimidine derivatives as scaffolds have been widely applied in the treatment of diseases. In this article, we summarized the reports on 4-aminopyrazolopyrimidine as well as its deformation and the application of its derivatives in designing small-molecule inhibitors and the treatment of diseases.
