The asymmetric unit of the title compound, C11H12N2O·C25H28N4O2, contains two different mol-ecules. The smaller is known as anti-pyrine [systematic name: 1,5-dimethyl-2-phenyl-1H-pyrazol-3(2H)-one] and the larger is built up from two antypirine mol-ecules which are connected through a C atom of the pyrazolone ring to a central propanyl part [systematic name: 4,4'-(propane-2,2-di-yl)bis-[1,5-dim...
متن کاملSynthesis, Characterization and Anti-Breast Cancer Activity of New 4-Aminoantipyrine-Based Heterocycles
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...
