With the aim of discovering potent and selective kinase inhibitors targeting ROS1 kinase, we designed, synthesized and screened a series of new pyrazol-4-ylpyrimidine derivatives based on our previously discovered lead compound KIST301072. Compounds I (R’ = H, Me) showed good to excellent activities against ROS1 kinase, and seven out of tested compounds were more potent than KIST301072. Compound I (R = CH₂CH₂CH₂CH₂OH, R’ = H) was the most potent with IC₅₀ of 24 nM. Moreover, compound I (R = CH₂CH₂CH₂CH₂OH, R’ = H) showed ROS1 inhibitory selectivity of about 170-fold, relative to that of ALK sharing about 49% amino acid sequence homol. with ROS1 kinase in the kinase domain. In silico modeling of 7c at ROS1 active site revealed some essential features for ROS1 inhibitory activity. Based on this study and the previous studies, we could build a hypothetical model predicting the required essential features for ROS1 inhibitory activity.
