Abstract
New heterocyclic chalcone analogues with pyridine-2,4(1 Н ,3 Н )-dione fragment were synthesized by the condensation reaction of 3-acetylpyridine-2,4(1 H ,3 H )-diones with different aromatic aldehydes in pyridine in the presence of a catalytic amount of piperidine and acetic acid. Structures of the synthesized compounds were confirmed by of IR, 1H, 13C NMR spectroscopy methods and two-dimensional NMR spectroscopy methods and elemental analysis data. Cytotoxic activity of the series of obtained compounds was investigated in vitro against human cell lines of breast cancer (MCF-7) and liver cancer (Hep G2).
