Tropomyosin receptor kinase (TRK) is an ideal target for treating cancers caused by the NTRK gene fusion. In this study, more than 60 2,4-diaminopyrimidine derivatives were prepared to understand the structure-activity relationship and confirm the rationality of the pharmacophore model reported previously. Among them, compound 19k was found to be a potent pan-TRK inhibitor that inhibits the proliferation of Km-12 cell lines. Additionally, compound 19k induced the apoptosis of Km-12 cells in a concentration-dependent manner. Western blot analysis revealed that compound 19k inhibited the phosphorylation of TRK to block downstream pathways. Compound 19k also possessed outstanding plasma stability and liver microsomal stability in vitro, with half-lives greater than 289.1 min and 145 min, respectively. Pharmacokinetic studies indicated that the oral bioavailability of compound 19k is 17.4%. These results demonstrate that compound 19k could serve as a novel lead compound for overcoming NTRK-fusion cancers.
