    Abstract:
    A series of eleven N-acryloyl/N-cinnamoyl 3,5-bis(pyridin-4-yl)methylene-4-piperidones were synthesized as curcumin-based candidate antineoplastic agents. The cytostatic potency of these compounds was evaluated against three representative cell lines and all compounds were found to exhibit significant anti-cancer cell activity in vitro. QSAR studies using several physicochemical parameters and 50% inhibitory concentration (IC50) values resulted in certain important correlations which will aid design of more potent analogs. Representative test compounds were investigated in the NCI 60-cell line panel where they were found to display a profound cytotoxicity. These compounds were also potent anti-oxidants and inhibitors of human topoisomerase IIα. Representative compounds were well-tolerated by human fibroblasts and by mice during the survival/toxicity studies.
