magnetic molecularly imprinted polymers synthesized by surface initiated reversible addition fragmentation chain transfer polymerization for the enrichment and determination of Synthetic Estrogens in aqueous solution
Journal of Separation Science, 2015Co-Authors: Fangfang Chen, Jingjing Zhang, Minjun Wang, Jie KongAbstract:Magnetic molecularly imprinted polymers have attracted significant interest because of their multifunctionality of selective recognition of target molecules and rapid magnetic response. In this contribution, magnetic molecularly imprinted polymers were synthesized via surface-initiated reversible addition addition-fragmentation chain transfer polymerization using diethylstilbestrol as the template for the enrichment of Synthetic Estrogens. The uniform imprinted surface layer and the magnetic property of the magnetic molecularly imprinted polymers favored a fast binding kinetics and rapid analysis of target molecules. The static and selective binding experiments demonstrated a desirable adsorption capacity and good selectivity of the magnetic molecularly imprinted polymers in comparison to magnetic non-molecularly imprinted polymers. Accordingly, a corresponding analytical method was developed in which magnetic molecularly imprinted polymers were employed as magnetic solid-phase extraction materials for the concentration and determination of four Synthetic Estrogens (diethylstilbestrol, hexestrol, dienestrol, and bisphenol A) in fish pond water. The recoveries of these Synthetic Estrogens in spiked fish pond water samples ranged from 61.2 to 99.1% with a relative standard deviation of lower than 6.3%. This study provides a versatile approach to prepare well-defined magnetic molecularly imprinted polymers sorbents for the analysis of Synthetic Estrogens in water solution.

effect of natural and Synthetic Estrogens on a549 lung cancer cells correlation of chemical structures with cytotoxic effects
Chemical Research in Toxicology, 2005Co-Authors: Silvana Andreescu, Omowunmi A. Sadik, D.w. McgeeAbstract:A series of Synthetic (nonylphenol, diethylstilbestrol, and bisphenol A) and natural (quercetin, resveratrol, and genistein) phenolic Estrogens were investigated for their ability to affect the viability and proliferation of A549 lung cancer cells. To assess and distinguish the cytotoxic effect of individual Estrogens, we used both the MTT tetrazolium spectrophotometric method and the fluorescence assay, while the induction of the cell specific apoptotic process was examined by fluorescence microscopy after treatment of cells with SYTO 24 green fluorescent dye. A systematic study of interferences for both fluorescence and MTT methods is presented. The results showed that both natural and Synthetic Estrogens decreased the viability and proliferation of A549 lung cancer cells in a dose-dependent manner but at different sensitivities. Nonylphenol appeared very different as compared to the other Estrogens, acting by inducing the higher inactivation rate of the cells within a very short time. The cytotoxic eff...
