low IC50 values in comparison with control drugs. In particular, for compound 8i, its IC50 value was 0.060 μM, suggesting its advantage as a focal adhesion kinase inhibitor. To evaluate the potentiality of these compounds as PET imaging agents in cancer detection, compounds 8a, 8c, 8h, and 8i were successively labeled with 18F. The four 18F-labeled pyrimidine derivatives showed appropriate log P values
基于计算机辅助药物设计,成功合成了一系列新型
