Abstract:
The present disclosure relates to a solid-phase process for the production of radiolabeled tracers, in particular for the production of 18F-labeled compounds which may be used as Positron Emission Tomography (PET) radiolabeled tracers. The disclosure also relates to radiopharmaceutical kits comprising precursors to the radiolabeled tracers, which can be converted to the radiolabeled tracers using the processes described herein.
Abstract:
[Problem] To provide a process suitable for mass-producing of iso-liquiritigenin.[Solution] A process for preparing iso-liquiritigenin, which comprises steps of coupling a 4-alkoxycinnamic acid represented by formula (I) with a 1,3-alkoxybenzene represented by formula (II) through the Friedel-Crafts reaction (A) to synthesize a tri-alkoxy-iso-liquiritigenin represented by formula (III), to crystallize out the reaction product, and eliminating the protecting groups therefrom to obtain iso-liquiritigenin, represented by formula (IV). The iso-liquiritigenin (IV), is administered as a precursor for liquiritigenin represented by formula (V) to the body, thereby obtaining in vivo a pharmacological effect of the (−) isomer of liquiritigenin.
