%X The synthesis of a new series of flurbiprofen hydrazide-hydrazones using microwave assisted reactions is described. Substituted aldehydes were condensed with flurbiprofen hydrazide by microwave irradiation to corresponding hydrazones. Synthesis of NĄŻ-[(4-bromothiophen-2-yl)methylidene]-2-(2-fluorobiphenyl-4-yl) propanehydrazide (3o) employing microwave assisted process resulted in higher yields, in faster time and with less chemical waste compared to traditional techniques. (2-fluorobiphenyl-4-yl)-NĄŻ-(phenylmethylidene)propanehydrazide (3p) andNĄŻ-[(2-chloro-6-fluorophenyl) methylidene]-2-(2-fluorobiphenyl-4-yl)propanehydrazide (3s) inhibited the growth of a leukemia cancercell line HL-60 (TB) by 66.37% and an ovarian cancer cell line OVCAR-4 by 77.34% (singledose, 10ŚĚM), respectively at the National Cancer Institute (NCI), but had no significant ef-fect on a panel of sixty human tumor cell lines. Flurbiprofen hydrazide-hydrazones were weak inhibitors of hepatitis C virus NS5B polymerase activity with NĄŻ-[(5-ethylfuran-2-yl)methylidene]-2-(2-fluorobiphenyl-4-yl)propanehydrazide (3m) being the most active of this series. Binding mode investigations of compound 3m suggested that allosteric pocket (AP)-B may be the potential binding site for flurbiprofen hydrazones and these results will alsoassist in further derivatization of 3m using the green chemistry approach and improve the potency of S-flurbiprofen hydrazide hydrazones
