چکیده
In the crystal of the title compound, C(17)H(17)N(3)O(2), the mol-ecules exist in the keto-enamine form. The pyrazole ring is oriented at 10.59 (4) and 57.98 (5)° to the phenyl and furyl rings, respectively, and the dihedral angle between phenyl and furyl rings is 73.30 (11)°. An intra-molecular N-H⋯O hydrogen bond occurs between imino and carbonyl groups. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into supra-molecular chains along the b axis.

4-Aminoantipyrine was utilized as key intermediate for the synthesis of pyrazolone derivatives bearing biologically active moieties. The newly synthesized compounds were characterized by IR, 1H- and 13C-NMR spectral and microanalytical studies. The compounds were screened as anticancer agents against a human tumor breast cancer cell line MCF7, and the results showed that (Z)-4-((3-amino-5-imino...
