title: Synthesis and anti-cancer activity of chalcone linked imidazolones.
abstract: A series of novel chalcone linked imidazolones were prepared and evaluated for their anti-cancer activity against a panel of 53 human tumour cell lines derived from nine different cancer types: leukemia, lung, colon, CNS, melanoma, ovarian, renal, prostate and breast. Some of these hybrids (6, 7 and 8) showed good anti-cancer activity with GI(50) values ranging from 1.26 to 13.9 microM. When breast carcinoma cells (MCF-7) were treated with 10 microM concentration of compounds TMAC, CA-4, 6 and 8 cell cycle arrest was observed in G2/M phase. Surprisingly, the increased concentration of the same compound to 30 microM caused accumulation of cells in G0/G1 phase of the cell cycle.
