Abstract: Pyrazolo[1,5-a]pyrimidines are fused heterocycles that have spawned many biologically
active antitumor drugs and are important privileged structures for drug development. Pyrazolo[1,5-
a]pyrimidine derivatives have played an important role in the development of antitumor agents due
to their structural diversity and good kinase inhibitory activity. In addition to their applications in
traditional drug targets such as B-Raf, KDR, Lck, and Src kinase, some small molecule drugs with
excellent activity against other kinases (Aurora, Trk, PI3K-γ, FLT-3, C-Met kinases, STING,
TRPC) have emerged in recent years. Therefore, based on these antitumor drug targets, small molecule
inhibitors containing pyrazolo[1,5-a]pyrimidine scaffold and their structure-activity relationships
are summarized and discussed to provide more reference value for the application of this particular
structure in antitumor drugs.
