چکیده
The title Schiff base compound, C(22)H(24)IN(3)O(2), adopts an E configuration about the central C=N bond. The pyrazolone ring makes a dihedral angle of 49.68 (10)° with its attached phenyl ring. The phenolate plane makes dihedral angles of 16.78 (9) and 50.54 (9)°, respectively, with the pyrazolone ring and the terminal phenyl ring. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring motif. In the crystal structure, an inter-molecular C-H⋯O hydrogen bond is also observed.

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...
