Özet

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 N'-[(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)-N'-(phenylmethylidene)propanehydrazide (3p) and N'-[(2-chloro-6-fluorophenyl) methylidene]-2-(2-fluorobiphenyl-4-yl)propanehydrazide (3s) inhibited the growth of a leukemia cancer cell line HL-60 (TB) by 66.37% and an ovarian cancer cell line OVCAR-4 by 77.34% (single dose, 10 mu M), respectively at the National Cancer Institute (NCI), but had no significant effect on a panel of sixty human tumor cell lines. Flurbiprofen hydrazide- hydrazones were weak inhibitors of hepatitis C virus NS5B polymerase activity with N'-[(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 also assist in further derivatization of 3m using the green chemistry approach and improve the potency of S-flurbiprofen hydrazide- hydrazones.
