Three new series of phenyl dihydropyridazinone derivatives 4b-8i have been designed, synthesized and evaluated for their anticancer activity against different cancer cell lines. Nine compounds showed strong inhibitory activity, among which compound 8b exhibited potent activity against PC-3 cell line with IC50 value of 7.83 µM in comparison to sorafenib (IC50 11.53 µM). Compounds 6a, 6c, 7f-h and 8a-d were further screened for their B-Raf inhibitory activity where seven compounds 7f-h and 8a-d showed high B-Raf inhibition with ranges of IC50 values 70.65-84.14 nM and 24.97-44.60 nM, respectively when compared to sorafenib (IC50 44.05 nM). Among the tested compounds, 8b was the most potent B-Raf inhibitor with IC50 value of 24.79 nM. Cell cycle analysis of MCF-7 cells treated with 8b showed cell cycle arrest at G2-M phase with significant apoptotic effect. Molecular modeling study was performed to understand the binding mode of the most active synthesized compounds with B-Raf enzyme. Copyright © 2020. Published by Elsevier Inc.
