Abstract | ||||
This study involved the design and synthesis of a novel series of oxindole-quinazoline hybrids targeting CDK2 in breast cancer. MTT assay investigated the cytotoxic activity of all the synthesized compounds 8a-e towards MCF-7 breast adenocarcinoma with IC50 ranging from 0.007 to 0.104 µM. The most active compound 8a was also evaluated for its cytotoxic activity on normal breast epithelial cell line MCF-10a cell line. The hybrid 8a demonstrated a high safety margin with SI = 10.57. Further assessment of 8a on its inhibitory activity on CDK2 proved its optimum potency with IC50 = 0.011 nM. Molecular docking of 8a in the binding pocket of CDK2 proved the expected binding mode. | ||||
