A novel series of 4-aryl-5,7-dihydro-6H-pyrrolo[2,3-d]pyrimidin-6-one derivatives were designed as a phosphoinositide 3-kinase α (PI3Kα) inhibitor by scaffold hopping. The target compounds, characterized by 1H-NMR, 13C-NMR and high resolution (HR)-MS, were synthesized from diethyl malonate and ethyl chloroacetate by nucleophilic substitution, ring-closure, chlorination and Suzuki reaction, etc. The biological activities were evaluated with cytotoxic activity in vitro on Uppsala 87 Malignant Glioma (U87MG) and prostate cancer-3 (PC-3) by Cell Counting Kit-8 (CCK-8). The results showed that compound 9c displayed the higher inhibition than the positive control PI-103, and high PI3Kα inhibitory activity with IC50 of 113 ± 9 nM in the same order of magnitude as BEZ235. In addition, the Log Kow values and molecular docking studies were performed to further investigate the drug-like properties of target compounds and interactions between 9c and PI3Kα.
