9, 10–14 and 16–18 showed higher activity compared to doxorubicin as a positive control. The radiosensitizing ability of the most promising compounds 4, 10 and 12 was studied which showed an increase in the cell killing effect of γ-radiation after combination with these derivatives. The molecular design was performed to predict the binding mode of the most promising compounds 4, 10 and 12 with the

2,4-dienoate (3). The bipyrazoline-5-carboxylate ester 4 underwent thermal elimination of hydrogencyanide upon heating in DMF to afford bipyrazole 10. Heating the 4,5'-bipyrazole derivative 4 in ethanolic sodium ethoxide solution afforded the bipyrazole 11 via concurrent decarboxylation and hydrogencyanide elimination. Oxidation of the latter product with tetrachloro-1,4-benzoquinone gave the 4,5'-bipyrazole
