✦ Synopsis


The in vitro dehalogenation of a series of para-substituted halobenzenes was studied using HPLC separation followed by scintillation counting or neutron-activation analysis. Microsomal and cytosolic deiodination were established for iodobenzene substrates whose para-substituents were CO2H, CHO, NO2, OH, and C6H5 but not for para-iodobenzonitrile. A nonglutathione cytosolic deiodinase was only indicated with 4-iodobiphenyl as the substrate. In vitro dehalogenation could not be established for 4-bromobiphenyl using neutron-activation analysis.
