摘要

In order to develop new imaging markers for brain hypoxia, two lipophilic nitroimidazoles, 1- (3-fluoropropyl)-2-nitroimidazole (FPN) and 1-(8-fluorooctyl)-2-nitroimidazole (FON) were synthesized and labeled with fluorine-18. The octanol/water partition coefficients were measured as an indication of lipophilicity, giving values of log P= 0.28 for FPN and log P= 2.72 for FON, respectively, which are in the range thought to be optimal for the diffusion of ...
