Pyrazolo[1,5-a]pyrimidines are fused heterocycles that have produced biologically active antitumor drugs and are crucial for drug development. They have shown structural diversity and good kinase inhibitory activity, leading to their important role in the development of antitumor agents. In addition to traditional drug targets, novel small molecules with excellent activity against other kinases have emerged. Therefore, this review focuses on the structure-activity relationships of pyrazolo[1,5-a]pyrimidine derivatives and their potential applications in antitumor drugs.
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-& gamma;, 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.
