Derivatives of thiocolchicine and its applications to CEM cells treatment using 19F magnetic resonance ex vivo.
2010
Abstract It was shown, that cultured ex vivo human T-Lymphoblastoid (CEM) cells respond to synthesized thiocolchicine and fluorine thiocolchicine derivatives. The preparation of derivatives with substitution at C-3 and C-7 is described. All compounds were used at concentration from 1 nM to 1000 nM. Inhibitory effects of these compounds were examined in the three-dimensional (3-D) culture and cells morphology during treatment was monitored using 9.4 T MRI system. We performed studies of these compounds in CEM cells ex vivo using 1 H and 19 F Magnetic Resonance Imaging (MRI), 19 F Magnetic Resonance Spectroscopy (MRS), High Performance Liquid Chromatography coupled with Ultra Violet (HPLC-UV) and Electron Impact Mass Spectrometry (EIMS). The results of the multi-technique approach are consistent with the fact that the new derivatives are more efficient than colchicine and thiocolchicine ex vivo .
