Abstract :
An irreversible ligand (7) has been prepared based on the selective I2 ligand 2-BFI. Compound 7 displayed high affinity and selectivity for I2-sites and has been shown to irreversibly bind to these sites in rat brain. Compound 7 should, therefore, prove an invaluable tool for the further elucidation of I2-site function.
