To obtain new anticancer agents with antimetastatic adjunct efficacy, a series of novel N4 -hydrazone derivatives of 5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one were designed and synthesized by an eight-step reaction, with appropriate yields. All the synthesized compounds were evaluated for their antiproliferative activity against A549 and MCF-7 cells and for antiplatelet aggregation activity in vitro. The results showed that compounds 25 and 35 not only showed potent antiproliferative activity against the A549 (IC50  = 15.3 and 21.4 μM) and MCF-7 (IC50  = 15.6 and 10.9 μM) cell lines but also showed certain antiplatelet aggregation activity (inhibition rates: 47.0% and 45.8%). These results indicated that the structural modification on the N4 -hydrazone moiety of 5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one is promising to obtain novel anticancer compounds with antimetastatic adjunct efficacy. In addition, a molecular docking study was performed to investigate the possible targets, and these results indicated that compounds 25 and 35 have the potential to target EGFR, HER2, and P2Y12 .
