Design, Synthesis, and Biological Evaluation of Novel Pyrazolo[1,5- a ]pyrimidine and 1,3-Benzodiazine Derivatives as Potent Antitumor Agents

Based on the molecular docking simulation and structure of larotrectinib, some larotrectinib derivatives as antitumor compounds were designed and synthesized. The antitumor activities of the synthesized compounds were tested by A549 and H1975 cell lines with larotrectinib as the positive control drugs. The molecular docking of the selected compounds with protein was carried out to further explain the binding modes and the ADME data of the compounds were predicted, which showed that the compounds had good physicochemical property and biological characteristics. The results showed that the selected compounds had further research potential.
