  名称：

  Synthesis and heme-binding correlation with antimalarial activity of 3,6-bis-(ω-N,N-diethylaminoamyloxy)-4,5-difluoroxanthone

  摘要：

  In this study, the effect of fluorine upon the heme-binding ability of the xanthone nucleus was investigated for 3,6-bis-((omega-N,N-diethylaminoamyloxy)-4,5-difluoroxanthone (F2C5). 2-Fluoro-1,3-dimethoxybenzene was prepared by a new, improved method and used to build up the xanthone nucleus. The interaction of F2C5 with heme was investigated by UV-vis, H-1 NMR, and F-19 NMR spectroscopy. For the first time, NMR studies for the heme-drug interactions are carried out at pH 5.0, physiological for the acidic food vacuole of the malaria parasite. (c) 2007 Elsevier Ltd.
