Abstract
We synthesized a new series of coumarin-piperazine 1,2,3-triazole hybrids (7a–7n) and screened for their in vitro anti-breast cancer activity against MCF-7, MDA-MB-468, and MDA-MB-231 cancer cell lines. The results revealed that compound 7f showed superior activity against all cell lines than the standard drug 5-fluorouracil. As well, compounds 7e, 7h, and 7k showed greater activity against MCF-7 than the positive control. Furthermore, 7f and 7h showed higher potency in inhibiting tyrosine kinase epidermal growth factor receptor (EGFR) than the standard drug erlotinib. Finally, in silico molecular docking studies on EGFR (PDB ID-4HJO) revealed that compounds 7e, 7f, 7h, and 7k possess good binding energies and inhibition constants as compared to erlotinib.
