Design and Synthesis of Fluorinated Dendrimers for Sensitive 19F MRI

To achieve high sensitivity for 19F MRI, a class of novel dendritic molecules with multiple pseudosymmetrical fluorines was designed and efficiently synthesized. Through iterative bromination and Williamson ether synthesis under mild conditions, a fluorinated dendrimer with 540 pseudosymmetrical fluorines was conveniently prepared without performing the group protection in a convergent way. The dendrimer is characterized by a strong 19F NMR peak and short relaxation times. Eventually, an appreciably enhanced 19F MRI at an extremely low concentration (18.5 μM) was achieved, which demonstrated the potential utility of such dendritic molecules in highly sensitive 19F MRI. (Chemical Equation Presented).

A dendritic macromolecule fluorine - 19 magnetic resonance developer and its preparation method and application (by machine translation)

The invention discloses a dendritic macromolecule fluorine - 19 magnetic resonance developer and its preparation method and application. Developer of the present invention is to fluorine-containing dendritic macromolecule as the skeleton, peripheral end group is connected with the functional molecule, its preparation method comprises the following steps: through the Lewis acid under the catalysis of the Friedel-crafts reaction of hexafluoroacetone with benzene will double-trifluoromethyl tertiary alcohol introduction benzene, in fuming sulfuric acid under the action of the iodination reaction, and then introduced into the propynyl structure through the coupling reaction, hydrogenating the resultant fluorine-containing structure unit Q; phosphorus tribromide in Q through the primary conversion of hydroxy group to bromine, then in hydroxy Q with the bromo generating ether linkage synthesis of 1st on behalf of the dendritic macromolecule, repeated brominated and ether generating reaction to obtain 2nd, three generations of dendritic macromolecule, finally through the brominated 3rd on behalf of the branched chain with the ligand through ether bond and to obtain the developer of the present invention. Developer of the present invention can be used for magnetic resonance imaging and the quantitative, visual, transmission and release and the like field. (by machine translation)
