    Abstract:
    In trying to develop new anticancer agents, a series of sulfonylhydrazones were synthesized. All synthesized compounds were checked for identity and purity using elemental analysis, TLC and HPLC and were characterized by their melting points, FT-IR and NMR spectral data. All synthesized compounds were evaluated for their cytotoxic activity against prostate cancer (PC3), breast cancer (MCF-7) and L929 mouse fibroblast cell lines. Among them, N'-[(2-chloro-3-methoxyphenyl)methylidene]-4-methylbenzenesulfonohydrazide (3k) showed the most potent anticancer activity against both cancer cells with good selectivity (IC50 = 1.38 μM on PC3 with SI = 432.30 and IC50 = 46.09 μM on MCF-7 with SI = 12.94). Further investigation confirmed that 3k displayed morphological alterations in PC3 and MCF-7 cells and promoted apoptosis through down-regulation of the Bcl-2 and upregulation of Bax expression. Additionally, compound 3k was identified as the most potent COX-2 inhibitor (91% inhibition) beside lower COX-1 inhibition. Molecular docking of the tested compounds represented important binding modes which may be responsible for their anticancer activity via inhibition of the COX-2 enzyme. Overall, the lead compound 3k deserves further development as a potential anticancer agent. Sulfonylhydrazones was synthesized and N'-[(2-chloro-3-methoxyphenyl)methylidene]-4- methylbenzenesulfonohydrazide (3k) was identified as the most potent anticancer agent and COX-2 inhibitor. In addition, this compound docked inside the active site of COX-2 succesfully.
