A series of urea-based compounds containing purine moieties were designed and synthesized as novel non-ATP competitive CHK1 inhibitors. The biological evaluation showed that several target compounds exhibited more potent inhibitory effects against CHK1 than the lead compound. In addition, one particular compound displayed synergistic effects with gemcitabine against HT29 cells.

Key words: CHK1 inhibitors, Non-ATP competitive, Anti-cancer synergistic effect
