moderate to low brain uptakes with little or no specific localization in hippocampal region, where 5-HT1A receptors are concentrated. These data indicate that the new iodinated ligands showed high binding affinities and better metabolic stability but displayed unexpectedly low selective binding to 5-HT1A receptors in vivo. Additional structural modifications may be needed to correct the unfavorable properties
